Hey from Holland. Do the two of you even half realize how useful all this information is to me as I am about to buy a property made of similar materials? I cannot thank you enough and your videos have definitely boosted my confidence about taking on a similar (albeit smaller) project .
I have seen old tradesmen take a shorter handle shovel to apply lime based products to walls. It is mixed and placed in a wheelbarrow and moved in the area of the wall. They take a half shovel full of rendering and throw it at the wall to consistently cover a patch and then trowel it out. It is fast and forces it into the mortar joints. The harder you throw, the deeper and flatter it 'splats' on the wall. Splats is a scientific word I just made up... lol.
I watch another cute couple who are using hemp bricks and then a hemp mixture (probably crete) behind the bricks to insulate their renovated, brick house in Belgium. It is quite a process for them (they have to drill holes in the bricks to secure each hemp brick.) Very interesting to see so many people are going to that as a source for insulation.
Much as I love the old stonework, of course you will have to insulate them. When they're finally all done you can hang a photograph on the wall to show what they looked like when you bought the place. With the solid, stable materials that you're using, this house will keep its residents comfortable for many generations into the future. And somewhere, I hope you will insert a bit of stone hidden behind the plaster with your names on it that secretly proclaims, "We did this".
We will be exposing some of the beautiful stonework, particularly one of the internal stone walls. It’s a fine balance between warmth/insulation and raw beauty 😀
Very interesting. The interest lies in the crazy things people did before you ... and what you're doing about it. Love your efforts. I especially like Kaleigh's (sp?) "Bye" at the end LOL.
I like the idea of hemp-crete. It's "breathable",reduces sound transmission, and insulates with natural materials that can be composted. There are hemp "panels" I have seen for sound reduction and insulation. Like cork or wood fibre, basically easily installed. Getting that hemp insulation might be the barrier (pun intended). Electrics look to be a real headache, but you've both figured out how to do things that stumped me. Congratulations.

Good to hear the "bye". at the end!! We still wait for it every time....Hehe! And chuckle afterwards....What a lesson in insulation. As South Africans, we just freeze for a week, about 3 times a season, or we sit in bed those three weeks....telling ourselves we need to do admin, then afterwards we go on with life, promising ourselves before next winter we will buy a coal stove to heat the house. And we never do it. But I must say, I often contemplating better insulated windows at least since I'm getting older. So we can't wait to see your practical solutions to insulate. A field we really know nothing about. You really inspired us to try making wine with our "Hanepoot" variety of which we have 3 pergolas full. We will have to dig a whole in the ground to make a wine room. Hope you will teach us how to make domestic wine as well one day?....all the best!!
I so look forward to all your videos, every week. My husband and I have been thinking of moving out of the US for a while now. Especially because of how our country is being run these days. All the research we've done, has lead us to Portugal. All the information you guys provide, has been so amazing! All the good AND the bad. . :) Thank you so much for all your information, it's helped us alot! :)
Great project and videos. I've only been watching for a couple of months and I'm starting to catch up on old videos. I think you will find that newer structures are required to have reinforced concrete posts at the corners and at intermittent positions with a reinforced concrete beam that runs around the top. The reinforcementsl is steel bars that are poured within the concrete box beams. This then forms a structural skeleton for the house and resists collapse or damage from earthquakes. It has the same effect to stabilize the house that steel posts and beams in commercial buildings do. Portugal is in an earthquake zone. While they aren't frequent, when they happen they can destroy cities e.g. Lisbon.
Have been watching lots of work with hemp on the channel De Hove old Belgian farmhouse renovation. They are using hemp blocks to insulate worth watching looks very good.
Hmm, wine. That's sounds very nice, but a whole year away...it will be hard to wait. With any luck maybe you can dig up a wine barrel. Wouldn't that be nice! Looks like you have enough projects to keep you busy for some time. All the better to learn from!
Getting insulation right (effective), whilst a lot of up front cost and work on a build like yours, will pay off in the long term. You'll both be sitting there comfortable in your dotage (I'm thinking you'll have to wait until you're in your 90s for dotage, the way you two are 😊 - that is a compliment!) thanking yourselves for all of the thought and hardwork you've put into this stage. I've had my first food crop fail (most of it) on my balcony garden - my garlic. It pays to follow sound instructions when you make your first attempt at growing something. which I did not do quite enough of. I've really enjoyed learning though and look forward to getting it more right for next year's planting. On a positive note, my Dwarf Meyer Lemon (her name is Lemonina) who lives in a large pot, is 6 years old (and has 'been through a lot' like her owner - but that's all on me, not her🙄😂) is coming back from the brink of another near death experience thanks to me learning some particular pruning techniques from an arborist who specialises in problematic fruit trees and doing some finely tuned specific mineral adjustments to the soil - because I messed up when I fertilised her last (potted citrus can get rather finicky about timing of such things - where I live anyway). I'm also about to embark on a new hobby - woodwork - but the right way. I'm going to start very small, with good quality, but only the bare necessity of handtools - because I like the idea of having put some grunt into achieving a result and being as I live in a total of 45m2, there aren't any huge projects going to happen any time soon. So.... quite a bit of my reinvigoration to get out there and try more things, have more of 'a go', has been inspired by you both. Thank you and keep up the great work.💖🐨💖
Hi just found you. Im undertaking a very similar project on my house here in south wales! Im at the same point in the insulation process as you. Lots of stone walls lots of holes lots of lime. Prices for everything gone through the roof here so trying to get what i want as a finished project at a reasonable cost is proving difficult. Lots of options. Keep up the good work ill keep watching!
Great video… I like all the different options and applications for your insulation plans. After you press the musk do the skins go to the chickens or can you add it the the compost bin? Thanks for sharing!
We have the chickens the spent grapes but they weren’t interested - put in the compost pile instead. So for the next batch we’ll use them to make vinegar
A great and informative video as always. Thank you🥰. However, the basic rule of insulation is that it should go to the cold side. The simple reason is that otherwise you will get condensation in the structure. In your case, the moisture will condensate somewhere within the stone walls. Furthermore, running electrical cables on the cold side of things can lead to condensation within the hull of the cable. I heard of cases where the water dripped out of the sockets. I understand that you don't want EPS or similar on the building, but maybe there is something hamp based that can be used on the outside?
That notion regarding condensation is typically correct when non natural/breathable materials are concerned. Using a lime/hemp material allows any moisture to pass through, and then be evaporated …. It’s also why we want breathable materials on both sides. The inside face of a 600mm wall thick stone wall really isn’t that cold either, it’s more tepid 😀
In case you’re interested, this is an interesting read(personally I think it’s fascinating) 😀 www.researchgate.net/publication/334442341_Application_of_hemp-lime_renders_to_improve_insulation_of_walls
@@MAKEDOGROW The term "breathable" is kind of a myth. No walls allow air to pass through. So I assume you are talking about the diffusion resistance of the materials. However, my hint was referring to the condensation point being within your wall. The condensation point for 20°C/60% air is roughly at 12°C which will probably be somewhere within your 60cm wall, resulting in the wall becoming wet in winter. Depending on the temperature gradient within the wall, this might happen close to your insulation layer. This effect is worse, the better your insulation works.
@@keyem4504 ah, not breathable in terms of air, but moisture. The stone walls with earthen mortar (and no dpc) means moisture will wick up from the earth … the lime as a ‘breathable’ material allows that moisture to pass out of the wall and evaporate. As opposed to materials like cement that trap the moisture within the wall. So even if the condensation point is in the wall, the lime and hemp-lime will allow that moisture to pass through. This moisture will then evaporate (helped by internal heating) and then be removed via ventilation (mechanical in our case). Our choice of materials is based on these natural building techniques, for which there is a load of documentation and research available
one traditional way of insulating (sound and thermal)?the ceiling of the ground floor is to fill the gap between the beams with little stones/gravel or dry dirt. Effective and inexpensive.
I went with Cornerstone insulated lime render for our Welsh stone house. Breathability as you guys know is very key! Wood-board is an option too but I’d say only on internal walls or window reveals (perhaps with wool behind and a moisture barrier. Ceilings - 8-16 cm sound insulating insulation :)
Great info, again...I like it! About the sun room: Kylie said you want to insulate with hemp crete, why not use hemp building blocks? Seems easier than filling the stud wall.
Thanks for answering questions. I have a couple: 1. The lime/sand infill on the stone looks great. Wondering if you considered not covering at least some of the walls with plaster of any sort. 2. I have stayed in old stone buildings in Portugal both summer and winter but often found it comfortable with limited heating/cooling. I am not aware of the heating and cooling cost differences if left uninsulated. So, other than the roof (which must be insulated), wondering whether you determined the importance of additional insulation as a cost factor, given that you will be using solar.
I love watching you solve these problems one by one!! As for the windows heating up the interior or allowing the cold in, have you considered adding interior shutters as a temporary relief until you are able to tackle the permanent solution?
Interesting! My limited experience of sound insulation found that material density and sealing of all gaps was key to success. Hence why concrete floors are far better than wood. Even the tiniest of gaps will transmit sound so doing this yourself will allow you to make sure everything is done right (rather than trusting a builder that knows you may never know how well it was done). I'm sure you've considered this but the external wall depth opens up possibilities for the glazing as well. Renovation of the original windows and adding secondary glazing being an interesting possibility? Thanks as ever for your content.
I'm looking forward to finding out how they plan to tackle the glazing. From memory they want to keep the original windows?? Not sure. I've seen some quite interesting work arounds to this with some restoration projects in Southern European countries.
@@permissiontoshine Indeed. It occurred to me that secondary glazing would allow time for refurbishment of the originals without leaving the house open and also mean it would be less important to look at double glazing which may well be impossible with the originals. Failing that remaking them but for double glazing wouldn't be too difficult (easier said than done of course).
Our current plan is to remake all the windows, mimicking the original style. We want double glazing but might start with a couple of single glazed ones as templates before moving on the double glazed. Side note - I’ve never made windows so I know it’s an ambitious plan, but I do like to challenge myself, and we have plenty of time 😃
@@MAKEDOGROW You will do great. You think things through, do your research and if it doesn't work out you fix it. I love that about you guys. It inspires me to think and work smarter. 💖🐨💖
I already know the answer (not Portuguese tradition) but I have always thought that a Queensland verandah would look great on the house, and what a fabulous way to keep the heat out of the house. Don't yell.
Funnily enough I was just doing some research on the weekend on those type of verandahs, to add to our outbuildings (when we redevelop them). We aren’t allowed to change the exterior facade of the house without planning permission, and as you rightly say it would take away from the traditional look we’re trying to maintain
The irony of a Queenslander (that's a big leap, potentially, from what you wrote) telling others not to yell, is not lost on me. 🤣 I do love those big, wide all the way around verandahs. We have quite a lot of those from a particular period is urban architecture here on the west coast and also many of our inland farm and station houses are built with them. Makes a lot of sense.
@@MAKEDOGROW I love that you are committed to maintaining much of the traditional look on the outside of your home. It kinda feels like the right thing to do in your situation.
I have seen someone else's build where they used hempcrete bricks with an infill behind the hempcrete bricks. It would save on having to build a stud wall. The stud wall would be a thermal bridge for hot and cold spots. Don't know if they can be bought where you live. The folks who used them were in the Netherlands.
Aren’t you negating the thermal storage of your thick stone walls by giving it an insulating hemp plaster layer? Good ‘boots’ and a good woolly ‘hat’ is all great - but the thick stone walls are giving you excellent temperature regulating property that you’d effectively insulate away. Since it’s still sunny in the winter, the stone walls will be warmed by the sun in the day and radiate the warmth at night - free heating… In the summer you could shade the south facing and west facing walls with deciduous greenery (tree or a climber on the wall surface) and it would prevent the sun from heating the stone… so the stone, in turn would hold and ‘radiate’ the cooler temperature into your living space - free cooling! If you still need a thick plaster to cover the electrics, you could use something less insulating (like cob?). Anyway - love your channel! This isn’t criticism, just maybe something to think about and see if it makes sense for you. All the very best!
Theory shows that hemp plaster will simply add to the insulation already provided by the stone walls. It’s also a misunderstanding that the stone walls warm up much in the winter here. There’s not enough sun hours, and the sun isn’t strong enough, to mitigate the cold that the walls absorb overnight. Stone houses here are freezing in the winter without internal heating. We didn’t realise how bad it was until we spent last winter here
G'day again from downunder Kylie and Guy It will be interesting to see how much space you lose once you put your insulation in. Are you going to re-use the same windows or put new double glazed ones in ? Have you thought of a name for your first bottles of wine ?
Great minds think alike. I was hanging in there to find out what their plans are with the windows but maybe they're saving that for an episode all of it's own. 😂
I was just wondering if you plan an inside staircase. I wouldn't want to go outside to go upstairs during winter. Wonderful to see how you guys are getting along. 🌹🐝🇿🇦
Here in the United States we put insulation in the new interior walls. This is for acoustic. Example people in the bathroom . You do not hear their business. I hope you might think it over. You might have it over there. We normally usually fiber glass comes in a roll. It has a paper backing. I think privacy can be a must.....................
Don't forget you could remove the single skin portuguese brick walls and replace with lime plastered straw bale walls which would have much better insulation properties and are really easy to work with and shape.
Something to think about when you start replacing windows. Ask yourself do you want fly screens? We live in Porto and would like screens, but our windows swing open like doors and we have the percianas de exterior (metal shades that roll down on the outside). So we can't figure out how to add screens without replacing the windows. Just something to think about.
@@MAKEDOGROW I am glad. Last year (even though we have a stone house), we got termites in our wood floors. We caught it very early and it was only upstairs under a window in the room we use for an office. A room where we opened up the window all the way in good weather (something we no longer do). We believe a queen (or whoever is in charge) flew/floated in from a ruin across the street and set up shop after slipping in between the crack of the wood floor. It was only a small area effecting two boards. I HIGHLY recommend prevention, because treatment (even caught early) was no picnic.
Thank you for this most informative video. One query: I am wondering why "only" apply 40mm hemp-lime plaster on the external stone walls compared to much thicker hempcrete elsewhere? Is it a case of not needing more insulation than this, a case of extensive drying times if going thicker or perhaps not wanting to loose more internal space? [or some other factor?]
Our stone walls are already 500-600mm thick and that already provides a good amount of insulation. So wheee we would have been just plastering walls we’re hemp-lime plastering instead …. 40mm is what we need to hide all the electrical cable and boxes etc. Drying time is also a consideration, each 20mm layer will take weeks to dry
Hi guys doing great work , I’m doing something very similar here in Ireland Weather a small bit different 🙈500mm stone walls with single leaf red brick under windows the builders must have been from Portugal🥲and I’ve concrete window sills that looked to be poured in situ which are taking In Water when we have prolonged rain , question should I take out sills and replace? I was going to cut a drip channel under them first a see would that make a difference, thanks
my neighbour just finished one wall of hemp lime insulation in her barn - a huge wall. She is an experienced builder and found that a wooden batten frame on the wall to the depth she wanted - which is probably the 40mm that you talk about works well to support the hemp lime as its being applied. She then could tack on boards to the frame so that she could fill behind the boards (which she then untacked and moved up when it just gone off) which provided the straight surface without too much bother?
That sounds more like hempcrete rather than hemp/lime plaster. Hemp plaster should have no issues sticking to the walls and holding itself up. We need to do 2 x 20mm coats, else the drying time gets too crazy
That was a lot of flies coming out of the bucket. You'll be lucky not to get infections or vinegar from that 😟 you really need a tight fitting lid and airlock
@@CLFL14256 I didn't go back and look but right as the cardboard was pulled away it looked like quite a lot of small flies flew up and out. Even if not, that's still a relatively risky approach given how simple the "proper" method is.
Not sure what you saw, but there were no flies. Airlock gets added during secondary fermentation after the must has been pressed … we’re following the traditional method which has been done successfully for decades and well documented in many wine making books
(I know I'm late to the party, but) What have you learned about any passive cooling or moisture control effects of the traditional Portuguese beam & tile roofs? Do the traditional roofs usually have some sort of sheathing under the tile? If not, I would expect convective air currents to provide some (a lot?) of ventilation & cooling during hot summer months - would you lose this benefit by closing off the roof space? (If you've answered this elsewhere, I apologize (but could you please point me in that direction?)). Also, I may have also missed your plans for dehumidifying- with all or these material absorbing & transferring & releaseing mosture, I'd expect that to become a factor at some point.
We find it’s the exact opposite of what you’re suggesting unfortunately. During the day the roof space heats up like a sauna (in the summer) and keeps the first floor very warm … we can literally feel the heat coming from above, unlike the ground floor which is very cool. And the opposite happens in the winter … the first floor is freezing as the roof allows so much cold in. There is no lining, just roof tiles on wooden beams and battens. To keep the hot/cold out we need to do a whole reroofing project to add in a thick layer of insulation. We’ll be adding a centralised ventilation system which will ventilate the entire house and control humidity. The lime and hemp plaster also has moisture control properties, yet another reason we chose it 😀
We have … but for the red brick walls where the staircase will be, we need some sturdy attach points … this will be provided by the timber framing within the hempcrete. We could work around this, but it would be more complicated. We’re hoping to use hemp bricks for another project though 😀
putting the hemp crete in direct contact with the outer wall and wood framing is fine with respect to vapor and moisture? Is the only “control” method for those the inherent breathability of the materials?
Well hello i am a fan of your channel. I would like to say, that you need to know better the properties of the material that the house is build of. Because when you say the stone walls dont have any kind of insulation, i think that's an error, because as you can experience in summer the down floor of the house is quite fresh, so the insulation is there. I Am an architect and my specialty is, old houses renovated, Stone houses, old timbers etc. If you like i can give you some tips. Best of luck
I don’t think that’s what we said (but we filmed that a while ago so I could be wrong) …. but I think what you’re referring to was when we were saying the lime we used to fill the holes in the stone wall has no insulation value. We’re very aware the thick stone walls have insulation value, the hemp plaster will just be adding to that. The sections under the windows, which aren’t very thick, definitely don’t do much in terms of insulation
Have you looked into cork infused NHL? Its expensive but may be worth it. Its suppose to be like dianthonite, and secil has an equivalent called secil tec ecocork

We have thermoflex, made by a German company called Gutex (they have loads of other insulation products). We get ours locally from a guy who imports loads of different building materials from all over the EU - in your in the Central region we can pass on his details if you’re interested
@@ninemoonplanet I thought the only addition for foamcrete was soap. But I certainly don't know. Concrete itself on the other hand, very bad for the environment. Does hempcrete use lime instead?
Sometimes when she's explaining something about a certain spot you keep the camera on her and don't show what she's actually talking about. It would just be nice to see what she's explaining. For example one of the times was when she's talking about above the window in the bathroom.
I guess when we pass out (from too much wine) on the floor that would add insulation 😂😂 We were actually talking about leca …we used it in the sub layers of the floor
I like your idea of an inside staircase so one does not need to go outside to access upstairs or downstairs.
With the window I would taper the wall from the window to the inner wall surface so you won't loose the width of the window opening from inside the room, just a thought 🤔
Still love the way Kylie says goodbye at the end.

I really admire you’re relenting bravery to identify the right method and materials in a subject you are unfamiliar with. Scary but doable.
I have seen old tradesmen take a shorter handle shovel to apply lime based products to walls. It is mixed and placed in a wheelbarrow and moved in the area of the wall. They take a half shovel full of rendering and throw it at the wall to consistently cover a patch and then trowel it out. It is fast and forces it into the mortar joints. The harder you throw, the deeper and flatter it 'splats' on the wall.

My husband I are impressed by your ethics and knowledge. I must ask Kylie. Do you have more than one coral sleeveless tshirt .
😂😂 just the one, it gets used well
🤣 The questions people ask on here. This made me chuckle
Great project and videos. I've only been watching for a couple of months and I'm starting to catch up on old videos.
I think you will find that newer structures are required to have reinforced concrete posts at the corners and at intermittent positions with a reinforced concrete beam that runs around the top. The reinforcementsl is steel bars that are poured within the concrete box beams. This then forms a structural skeleton for the house and resists collapse or damage from earthquakes. It has the same effect to stabilize the house that steel posts and beams in commercial buildings do.
Portugal is in an earthquake zone. While they aren't frequent, when they happen they can destroy cities e.g. Lisbon.
For the floor above you can take a look at Pavacoustic. It's a top floor product made of OSB and woodfiber.
Have been watching lots of work with hemp on the channel De Hove old Belgian farmhouse renovation. They are using hemp blocks to insulate worth watching looks very good.
Sounds a daunting task. I wish you luck x
Thanks for the update, and these videos are just terrific!
Batt is the word you were looking for 😄
A batten is a wood strip - a sheet of insulation is a batt.
Hmm, wine. That's sounds very nice, but a whole year away...it will be hard to wait. With any luck maybe you can dig up a wine barrel. Wouldn't that be nice! Looks like you have enough projects to keep you busy for some time. All the better to learn from!
Getting insulation right (effective), whilst a lot of up front cost and work on a build like yours, will pay off in the long term. You'll both be sitting there comfortable in your dotage (I'm thinking you'll have to wait until you're in your 90s for dotage, the way you two are 😊 - that is a compliment!) thanking yourselves for all of the thought and hardwork you've put into this stage.
I've had my first food crop fail (most of it) on my balcony garden - my garlic. It pays to follow sound instructions when you make your first attempt at growing something. which I did not do quite enough of. I've really enjoyed learning though and look forward to getting it more right for next year's planting.
On a positive note, my Dwarf Meyer Lemon (her name is Lemonina) who lives in a large pot, is 6 years old (and has 'been through a lot' like her owner - but that's all on me, not her🙄😂) is coming back from the brink of another near death experience thanks to me learning some particular pruning techniques from an arborist who specialises in problematic fruit trees and doing some finely tuned specific mineral adjustments to the soil - because I messed up when I fertilised her last (potted citrus can get rather finicky about timing of such things - where I live anyway).
I'm also about to embark on a new hobby - woodwork - but the right way. I'm going to start very small, with good quality, but only the bare necessity of handtools - because I like the idea of having put some grunt into achieving a result and being as I live in a total of 45m2, there aren't any huge projects going to happen any time soon.
So.... quite a bit of my reinvigoration to get out there and try more things, have more of 'a go', has been inspired by you both. Thank you and keep up the great work.💖🐨💖
Hi just found you. Im undertaking a very similar project on my house here in south wales! Im at the same point in the insulation process as you. Lots of stone walls lots of holes lots of lime. Prices for everything gone through the roof here so trying to get what i want as a finished project at a reasonable cost is proving difficult. Lots of options. Keep up the good work ill keep watching!
I found it fascinating!
This will be a very interesting insulation journey 😊 We are going to learn a lot as you try, adapt and succeed. 👌👍
Love the sun room. This home is going to be even more beautiful when your done with all your renovations. Enjoy following you on your journey 😊
Great video… I like all the different options and applications for your insulation plans. After you press the musk do the skins go to the chickens or can you add it the the compost bin? Thanks for sharing!
We have the chickens the spent grapes but they weren’t interested - put in the compost pile instead. So for the next batch we’ll use them to make vinegar
Well now, when presented like you've done, it's very interesting!
A great and informative video as always. Thank you🥰.
However, the basic rule of insulation is that it should go to the cold side. The simple reason is that otherwise you will get condensation in the structure. In your case, the moisture will condensate somewhere within the stone walls.
Furthermore, running electrical cables on the cold side of things can lead to condensation within the hull of the cable. I heard of cases where the water dripped out of the sockets.
I understand that you don't want EPS or similar on the building, but maybe there is something hamp based that can be used on the outside?
That notion regarding condensation is typically correct when non natural/breathable materials are concerned. Using a lime/hemp material allows any moisture to pass through, and then be evaporated …. It’s also why we want breathable materials on both sides.
The inside face of a 600mm wall thick stone wall really isn’t that cold either, it’s more tepid 😀
In case you’re interested, this is an interesting read(personally I think it’s fascinating) 😀

@@MAKEDOGROW Hi, thanks for the link. Interesting read for sure.
@@MAKEDOGROW The term "breathable" is kind of a myth. No walls allow air to pass through. So I assume you are talking about the diffusion resistance of the materials.
However, my hint was referring to the condensation point being within your wall. The condensation point for 20°C/60% air is roughly at 12°C which will probably be somewhere within your 60cm wall, resulting in the wall becoming wet in winter.
Depending on the temperature gradient within the wall, this might happen close to your insulation layer.
This effect is worse, the better your insulation works.
@@keyem4504 ah, not breathable in terms of air, but moisture. The stone walls with earthen mortar (and no dpc) means moisture will wick up from the earth … the lime as a ‘breathable’ material allows that moisture to pass out of the wall and evaporate. As opposed to materials like cement that trap the moisture within the wall.
So even if the condensation point is in the wall, the lime and hemp-lime will allow that moisture to pass through. This moisture will then evaporate (helped by internal heating) and then be removed via ventilation (mechanical in our case).
Our choice of materials is based on these natural building techniques, for which there is a load of documentation and research available
*You two are doing it... finding the right way that suits your home... rock onto the next video.*
one traditional way of insulating (sound and thermal)?the ceiling of the ground floor is to fill the gap between the beams with little stones/gravel or dry dirt. Effective and inexpensive.
Weight insulates sound, air insulates heat/cold 😉
Please watch “De Hoeve “ on RUclips they used the hemp insulation in their Reno …. It looks really good 👍
Wow!!! Never realized insulation was so complicated. Seems Kylie is getting a handle on it. Best to you both.
I went with Cornerstone insulated lime render for our Welsh stone house. Breathability as you guys know is very key! Wood-board is an option too but I’d say only on internal walls or window reveals (perhaps with wool behind and a moisture barrier. Ceilings - 8-16 cm sound insulating insulation :)
Always fascinating and educational. Such a variety of problems and solutions required for your interesting house!!
Hugs from 🇨🇦
Another very informative episode! Thank you, Kylie and Guy❤️❤️
Great info, again...I like it! About the sun room: Kylie said you want to insulate with hemp crete, why not use hemp building blocks? Seems easier than filling the stud wall.
Good call. I've recently watch a couple renovating an old building in Belgium do just that. Worth considering.
Thanks for answering questions. I have a couple:
1. The lime/sand infill on the stone looks great. Wondering if you considered not covering at least some of the walls with plaster of any sort. 2. I have stayed in old stone buildings in Portugal both summer and winter but often found it comfortable with limited heating/cooling. I am not aware of the heating and cooling cost differences if left uninsulated. So, other than the roof (which must be insulated), wondering whether you determined the importance of additional insulation as a cost factor, given that you will be using solar.
Lots of work and a big Commitment. ❤
I have nothing to say really, but I appreciate your content, and wish to help with the yt-algorithms.
I love watching you solve these problems one by one!! As for the windows heating up the interior or allowing the cold in, have you considered adding interior shutters as a temporary relief until you are able to tackle the permanent solution?
Even curtains might help some.
Interesting! My limited experience of sound insulation found that material density and sealing of all gaps was key to success. Hence why concrete floors are far better than wood. Even the tiniest of gaps will transmit sound so doing this yourself will allow you to make sure everything is done right (rather than trusting a builder that knows you may never know how well it was done). I'm sure you've considered this but the external wall depth opens up possibilities for the glazing as well. Renovation of the original windows and adding secondary glazing being an interesting possibility? Thanks as ever for your content.
I'm looking forward to finding out how they plan to tackle the glazing. From memory they want to keep the original windows?? Not sure. I've seen some quite interesting work arounds to this with some restoration projects in Southern European countries.
@@permissiontoshine Indeed. It occurred to me that secondary glazing would allow time for refurbishment of the originals without leaving the house open and also mean it would be less important to look at double glazing which may well be impossible with the originals. Failing that remaking them but for double glazing wouldn't be too difficult (easier said than done of course).
@@jonathankeenan5163 good point. They have so much to think of and plan out.
Our current plan is to remake all the windows, mimicking the original style. We want double glazing but might start with a couple of single glazed ones as templates before moving on the double glazed.
Side note - I’ve never made windows so I know it’s an ambitious plan, but I do like to challenge myself, and we have plenty of time 😃
@@MAKEDOGROW You will do great. You think things through, do your research and if it doesn't work out you fix it. I love that about you guys. It inspires me to think and work smarter. 💖🐨💖
I was strangely captivated about insulation!! I’m now questioning my life 🤣🤣🤣
😂🤣😂
I already know the answer (not Portuguese tradition) but I have always thought that a Queensland verandah would look great on the house, and what a fabulous way to keep the heat out of the house. Don't yell.
Funnily enough I was just doing some research on the weekend on those type of verandahs, to add to our outbuildings (when we redevelop them).
We aren’t allowed to change the exterior facade of the house without planning permission, and as you rightly say it would take away from the traditional look we’re trying to maintain
The irony of a Queenslander (that's a big leap, potentially, from what you wrote) telling others not to yell, is not lost on me. 🤣 I do love those big, wide all the way around verandahs. We have quite a lot of those from a particular period is urban architecture here on the west coast and also many of our inland farm and station houses are built with them. Makes a lot of sense.
@@MAKEDOGROW I love that you are committed to maintaining much of the traditional look on the outside of your home. It kinda feels like the right thing to do in your situation.
its actually called Mash and you are meant to do a punch down at least once per day.to remove the bubbles.caused by the fermentation process.
Look at De Hoeve, old belgian farm renovation. They use Hemp blocks.
Illia from "De Hoeve" Old Belgian Farm House. Is installing hempcrete in his old brick house!
Bye , back to work ,what a lot to do ❤️❤️👋👋👏👏🙏🏻
I have seen someone else's build where they used hempcrete bricks with an infill behind the hempcrete bricks. It would save on having to build a stud wall. The stud wall would be a thermal bridge for hot and cold spots. Don't know if they can be bought where you live. The folks who used them were in the Netherlands.
Nice job 😊🎉
You can trying asking to the Leroy Merlin about isolate or other things, they help people with good suggestions 😊🤗
Unfortunately Leroy Merlin know nothing about natural building solutions
Aren’t you negating the thermal storage of your thick stone walls by giving it an insulating hemp plaster layer?
Good ‘boots’ and a good woolly ‘hat’ is all great - but the thick stone walls are giving you excellent temperature regulating property that you’d effectively insulate away. Since it’s still sunny in the winter, the stone walls will be warmed by the sun in the day and radiate the warmth at night - free heating…
In the summer you could shade the south facing and west facing walls with deciduous greenery (tree or a climber on the wall surface) and it would prevent the sun from heating the stone… so the stone, in turn would hold and ‘radiate’ the cooler temperature into your living space - free cooling!
If you still need a thick plaster to cover the electrics, you could use something less insulating (like cob?).
Anyway - love your channel! This isn’t criticism, just maybe something to think about and see if it makes sense for you.
All the very best!
Theory shows that hemp plaster will simply add to the insulation already provided by the stone walls.
It’s also a misunderstanding that the stone walls warm up much in the winter here. There’s not enough sun hours, and the sun isn’t strong enough, to mitigate the cold that the walls absorb overnight. Stone houses here are freezing in the winter without internal heating. We didn’t realise how bad it was until we spent last winter here
For the roof. If you use Gutex Multiplex Top, on top of the stucture, underneath the counterbattens, then you dont need a membrame.
G'day again from downunder Kylie and Guy
It will be interesting to see how much space you lose once you put your insulation in. Are you going to re-use the same windows or put new double glazed ones in ?
Have you thought of a name for your first bottles of wine ?
Great minds think alike. I was hanging in there to find out what their plans are with the windows but maybe they're saving that for an episode all of it's own. 😂
I was just wondering if you plan an inside staircase. I wouldn't want to go outside to go upstairs during winter. Wonderful to see how you guys are getting along. 🌹🐝🇿🇦
Here in the United States we put insulation in the new interior walls. This is for acoustic. Example people in the bathroom . You do not hear their business. I hope you might think it over. You might have it over there. We normally usually fiber glass comes in a roll. It has a paper backing. I think privacy can be a must.....................
Yep, we have gutex (wood fibre insulation) for our one internal stud wall - it provides both acoustic and thermal properties
Don't forget you could remove the single skin portuguese brick walls and replace with lime plastered straw bale walls which would have much better insulation properties and are really easy to work with and shape.
Since you live in Portugal, you might consider spray cork instead of plaster.
Something to think about when you start replacing windows. Ask yourself do you want fly screens? We live in Porto and would like screens, but our windows swing open like doors and we have the percianas de exterior (metal shades that roll down on the outside). So we can't figure out how to add screens without replacing the windows. Just something to think about.
We’ll be making our own and have already worked out how screen fit into the design.
We’re also quite lucky that both window and shutters open inwards
@@MAKEDOGROW I am glad. Last year (even though we have a stone house), we got termites in our wood floors. We caught it very early and it was only upstairs under a window in the room we use for an office. A room where we opened up the window all the way in good weather (something we no longer do). We believe a queen (or whoever is in charge) flew/floated in from a ruin across the street and set up shop after slipping in between the crack of the wood floor. It was only a small area effecting two boards. I HIGHLY recommend prevention, because treatment (even caught early) was no picnic.
Have you watched De Hoeve on YT they used the hemp for their insulation on an old Belgium farm house.
Can Kylie tell us more anout her Australian adventure i.e. where, what, when, who and why?
Do u have pet's? By end October all pet's must be registered in Portugal.
Thank you for this most informative video. One query: I am wondering why "only" apply 40mm hemp-lime plaster on the external stone walls compared to much thicker hempcrete elsewhere? Is it a case of not needing more insulation than this, a case of extensive drying times if going thicker or perhaps not wanting to loose more internal space? [or some other factor?]
Our stone walls are already 500-600mm thick and that already provides a good amount of insulation. So wheee we would have been just plastering walls we’re hemp-lime plastering instead …. 40mm is what we need to hide all the electrical cable and boxes etc. Drying time is also a consideration, each 20mm layer will take weeks to dry
Hi guys doing great work ,
I’m doing something very similar here in Ireland
Weather a small bit different 🙈500mm stone walls with single leaf red brick under windows the builders must have been from Portugal🥲and I’ve concrete window sills that looked to be poured in situ which are taking In Water when we have prolonged rain , question should I take out sills and replace? I was going to cut a drip channel under them first a see would that make a difference, thanks
my neighbour just finished one wall of hemp lime insulation in her barn - a huge wall. She is an experienced builder and found that a wooden batten frame on the wall to the depth she wanted - which is probably the 40mm that you talk about works well to support the hemp lime as its being applied. She then could tack on boards to the frame so that she could fill behind the boards (which she then untacked and moved up when it just gone off) which provided the straight surface without too much bother?
That sounds more like hempcrete rather than hemp/lime plaster. Hemp plaster should have no issues sticking to the walls and holding itself up. We need to do 2 x 20mm coats, else the drying time gets too crazy
@@MAKEDOGROW yep; interesting scent whilst drying too..😄 its pretty impressive as an insulation on an exterior (inside) wall.
Another RUclipsr recently used hemp for the same reasons you talked about. The hemp & lime looked like larger bricks.
That was a lot of flies coming out of the bucket. You'll be lucky not to get infections or vinegar from that 😟 you really need a tight fitting lid and airlock
my eyesight must be shot, I saw no flies, possibly one but that could have been a lens flare
@@CLFL14256 I didn't go back and look but right as the cardboard was pulled away it looked like quite a lot of small flies flew up and out. Even if not, that's still a relatively risky approach given how simple the "proper" method is.
Not sure what you saw, but there were no flies.
Airlock gets added during secondary fermentation after the must has been pressed … we’re following the traditional method which has been done successfully for decades and well documented in many wine making books
(I know I'm late to the party, but) What have you learned about any passive cooling or moisture control effects of the traditional Portuguese beam & tile roofs? Do the traditional roofs usually have some sort of sheathing under the tile? If not, I would expect convective air currents to provide some (a lot?) of ventilation & cooling during hot summer months - would you lose this benefit by closing off the roof space? (If you've answered this elsewhere, I apologize (but could you please point me in that direction?)). Also, I may have also missed your plans for dehumidifying- with all or these material absorbing & transferring & releaseing mosture, I'd expect that to become a factor at some point.
We find it’s the exact opposite of what you’re suggesting unfortunately. During the day the roof space heats up like a sauna (in the summer) and keeps the first floor very warm … we can literally feel the heat coming from above, unlike the ground floor which is very cool. And the opposite happens in the winter … the first floor is freezing as the roof allows so much cold in. There is no lining, just roof tiles on wooden beams and battens. To keep the hot/cold out we need to do a whole reroofing project to add in a thick layer of insulation.
We’ll be adding a centralised ventilation system which will ventilate the entire house and control humidity. The lime and hemp plaster also has moisture control properties, yet another reason we chose it 😀
Have you Considered Laying mall width hemp bricks & filling the gap with hempcrete.
We have … but for the red brick walls where the staircase will be, we need some sturdy attach points … this will be provided by the timber framing within the hempcrete. We could work around this, but it would be more complicated.
We’re hoping to use hemp bricks for another project though 😀
putting the hemp crete in direct contact with the outer wall and wood framing is fine with respect to vapor and moisture? Is the only “control” method for those the inherent breathability of the materials?
Well hello i am a fan of your channel.
I would like to say, that you need to know better the properties of the material that the house is build of.
Because when you say the stone walls dont have any kind of insulation, i think that's an error, because as you can experience in summer the down floor of the house is quite fresh, so the insulation is there.
I Am an architect and my specialty is, old houses renovated, Stone houses, old timbers etc.
If you like i can give you some tips.
Best of luck
I don’t think that’s what we said (but we filmed that a while ago so I could be wrong) …. but I think what you’re referring to was when we were saying the lime we used to fill the holes in the stone wall has no insulation value. We’re very aware the thick stone walls have insulation value, the hemp plaster will just be adding to that. The sections under the windows, which aren’t very thick, definitely don’t do much in terms of insulation
Have you looked into cork infused NHL? Its expensive but may be worth it. Its suppose to be like dianthonite, and secil has an equivalent called secil tec ecocork
Yes, we have looked at it but are trying to avoid having to use NHL on our walls
Elephants are very quiet it would be a herd of buffalo because as I believe a family of elephant
Sorry elephants are my favourite animals? Adorable don’t remember a lot of things and I’m just so so cute.
I think your house is absolutely amazing and beautiful and if I could help you guys out I totally would but I live in Canada and you live in Portugal.
Do you have any more detail on the wood fiber please. We have a similar job to do, and I'm looking at all sorts of solutions. Thank you
Ps we are also in Portugal so if you can get it, we can too
We have thermoflex, made by a German company called Gutex (they have loads of other insulation products). We get ours locally from a guy who imports loads of different building materials from all over the EU - in your in the Central region we can pass on his details if you’re interested
@@MAKEDOGROW That would be fabulous. We are central. Near Aveiro. So Central coasty type thing 👍
It's a bit sad to loose all the pretty stone walls behind the insulation.
They won’t all be lost, we do plan to point and expose some
بالتوفيق
Are y’all going to make some of it an air b&b or a bed & breakfast? Will you allow people to come stay and help y’all short term?
Given all the work yet to do on the house, do you have an estimate of when you might move in?
2030 😂🤣😀
Are you doing a LIME WASH COAT on the out side walls. to bring out the colour of the house
Eventually, yes. There’s quite a bit of work to do externally to the house before that though (removing some cement render and lots of patch work)
How willyou be installing the electrical circurts in each room
🍻🍻🍻
Wouldn’t an electric mortar gun work faster as it’s pressurized and then just trowel it in as you go?
the best isolation material it's cork ..
I'm sure you've covered this question, but in terms of insulation, foamcrete?
I think they want to steer clear of chemicals, fossil fuel industrial products. Hemp-crete is actually compostable, foam definitely isn't.
@@ninemoonplanet I thought the only addition for foamcrete was soap. But I certainly don't know. Concrete itself on the other hand, very bad for the environment. Does hempcrete use lime instead?
I rent a small appartment,,,, Im just fine. No digging no damp problem
De Hoeve
Sometimes when she's explaining something about a certain spot you keep the camera on her and don't show what she's actually talking about. It would just be nice to see what she's explaining. For example one of the times was when she's talking about above the window in the bathroom.
Do you really mean that licquor has insulation properties on the floor?
I guess when we pass out (from too much wine) on the floor that would add insulation 😂😂
We were actually talking about leca …we used it in the sub layers of the floor
