I uused the same roof construction on my extension. I cut thr roof in for a close fit. There are fill in panels in the catalogue on Kingspan's website. Good job for a skilled fitter team.
Top job ! You mention additional insulation to the underside.....not just a good idea to further increase the insulation vale ( future proofing) but also to prevent thermal bridging through the fixings into the purlins. Insulation and air tightness go hand in hand, do them both right when you have the chance, you'll never look back. Back in 2007/8 we completed a traditional barn conversion ( 700m2 of it). Having reroofed the lot, we had closed cell SFI applied to the underside of the membrane, between and under rafter...350mm of it. Likewise , the walls 200mm of it behind and between C channel studwork. Heating requirement approx 13w/m2 ( not quite passivhaus at 10w/m2, but not bad for an amateur ) . Looking forward to watching further progress.
Had to watch back to get the Kingspan reference! Was planning on using a Zinc roof insulated underneath my own garage but the ease of this installation has me planning a pivot!! Thanks again for all the great content, best of luck with the project.
Having lived in many metal roofed homes in Australia, rain noise has never been an issue, just simply don’t hear it even at night. These were metal roofs without any bonded insulation.
Hi there, we’re ex pats living in California in a 1970’s ranch style house. We have some velux style windows (lots of heat from them) but also use solar tubes. Not sure if they are available in the UK but if so you might consider them as alternatives for rooms that get too hot with Velux windows but still need daylight. The incoming heat is negligible and light shed is fantastic. No need for lights on in the daytime plus they have bulbs fitted for night use. Thank you for all the effort you make sharing your knowledge - always look forward to watching your progress.
I had to comment and tell you what a beautiful job you are making of your new house you will all deserve it when it is finally finished, I bet you cannot wait, Michael
I did a similar build in 2016 all beit slightly smaller. I was talked out of my kingspan roof because of the constant cracking and banging from thermal movement. When i contacted Kingspan for some advice, they advised me that their roofing system was not for Domestic use and the roof would expand and contract throughout the day all year round and that this does produce some noise. I visited a friends commercial Barn that had the same roof i desired, i was shocked at how much it banged and creaked as the morning sun hit it. I hope you dont have the same issues, but would be interested to hear your thoughts. As it would have driven me insane.
It does make some noises in heat but mainly coming from the eaves where the sheets are yet to be secured down to the new walls. Once the ceilings are up I’m hoping it will be reduced further. 🤞
We are doing something similar barn build 1/2 way ish……. We Have got the same roof insulated panel although it’s classed as a warm Roof they still wanted us to insulate the ceilings seems crazy but. Tbh it’s not a bad idea as you do hear the rain it’s not a terrible sound because it is lessened actually quite relaxing. We have 1/2 vaulted and half covered . Just a couple of things the box Guttering is not a bad idea. Firstly, it’s very neat and acts a bit of a facia board as it comes down and covers quite a lot . The reason it’s good they are very deep and the amount of rain that slides off that Roof is fast the conventional guttering system would not take it I would look into it. It’s a neat finish and cut back on the insulation panel is designed for it and it covers the insulation cuts . The roof does work well keeps it cool inside in the summer. Second thing, shame you’re sticking solar panels on that roof . Could you not stick them on the the building you have next to it ? be a shame to put them on? Are you also going to add sun tunnels? We just looking into it. Are you also having an air source heat pump. Keep up the work 👍🏻
I hadn’t ruled out the guttering completely but was looking a more agricultural large half round like it was before. Would need some calculating to make sure flow rate was sufficient though.
We will add a small amount at ceiling level however adding any significant amount would probably be worth a condensation risk analysis just to make sure the inner skin of the composite never becomes too cold and leave moisture in the build up. Going to make that decision later in build once we feel how well it’s working.
Yer good idea We was advised with a minimum 50 mil airflow on the vaulted ceiling . the others are just ceilings so it has plenty of flow We was told any condensation is designed to run on the underside ridges down and out if that makes sense. As they sit on our top plate so it works out. There’s very small gap on every ridge on the underside where it meets the edge of the building. We was advised not to foam for this as it also acts as a flow. Probably a bit different for you because you’re keeping it as a hot Roof . looking forward for the next videos been helpful and interesting
@@belucky9630 Thanks for your input on this warm roof/cold roof question, as I understand it a warm roof has the insulation above the roof, everything else is a cold roof and requires venting as was specified on your build. Perhaps Tim's roof will end up being vented above the ceiling where the purlins are??? I am not doubting what you say about the warm roof classification, however it is fair to say correctly vented cold roofs don't fail whereas 'hybrid' roofs do on a regular basis. FWIW I can see why you would insulate above the ceiling as otherwise you would get heat loss where the plasterboard and void above are cold. I think what is going on is the roof has to do many jobs, it's got to keep heat in but let moisture escape so the roof doesn't 'sweat'.
@@TheRestorationCouple Would be good to hear more about how this roof works in terms of moisture and condensation. And also why they call it a warm roof when the insulation is below the roof???
Skylights: nice, but on hot summer days it WILL get awfully hot inside, unless you get the light to stay outside on those days... I know from experience in exactly the same setup. It was remedied by having solar panels drive the AC
Interesting video, my thought was why not. Warm roof to keep the rain off, done in a day, what’s not to like. With a roof that size what size is gutter? A deluge would produce a ridiculous amount of water!
Give Oval Renewables a call for the Solar, fellow youtubers, so you could get a bit of a collaboration going. Fantastic work ethic by yourself and them.
Hi mate, roof looks amazing. Great work. I'd definitely go for all black solar panels. I'd say go for heat pump as I have a aurothom plus and it's amazing. They work in see way as gas but 350% plus better. Get big tank too and zone it.
Sorry if this is too basic a question but what is to stop warm air moisture going through the plasterboard and then rapidly cooling on the steel and metal purlins above??? Is the idea that the MVHR system ensures this never happens??? With regards to sunpipes they would have to be protected against upward light spill in the same way as the rooflights have to be, there is also the question that they are not an element found on agricultural buildings like rooflights are, worst ways that could mean going back to planning. Another aspect with the windows is the technical aspect of which are the escape/rescue windows for the fire regs if you are on an escape window plan. Perhaps you could go with a deeper gap filled with gas between the glazing on the rooflights, surely there is a solution for heat gain???
@@dannymurphy1779 yes you said it yourself. Below the insulation so warm. Condensation would only be an issue if metalwork was outside the insulated envelope of the building or bridging through the insulation.
I came to ask something similar, but rather than condensation specifically, I want to know if they thought about the general buildup of moisture. I guess it's not that important for somewhere you're not spending ages sweating, cooking, or showering, but isn't there the possibility that moisture will build up in there with nowhere to go... making all your tools rusty and whatnot?
What sort of technology are you looking to include in the final build? You must have terabytes of footage for example, so are you considering including a server room? What about smart home products - are you considering audio or lighting? Or going “old fashioned” with regular lights and switches?
We have flat ceilings in most of it so was easier to just use loft insulation, plus the cabin had to be able to split in half so would need more engineering for ridge beams. Could have worked though.
Nice job and overview! What was the name of the roof window company that retrofit to these roof sheets? thanks. also what was the gap sealing method used between the sheet over laps?
Correct me if I’m wrong but If yours is 150mm Quadcore then it should be fine at 0.12 W/m²K? (Building regs part L and for new elements in existing dwellings, the U values for roofs is 0.15 W/m²K). Assuming yours is not a new build as such?
Looks fantastic! I'm considering using the same roofing on my garage, with the intention of adding solar once it's up. Is there some way of preparing the roof so adding solar is easier? How easy is it to add solar to this kind of roof, do you know?
There are brackets made for this profile. Some approved some not so depends on if the install is MCS. Either way, it’s a very simple type of roof for brackets compared to tiles.
The big question! 😂 Hard to say as the only way we can do it is to take longer and do as much as we can ourselves, no crazy urgency to hit a deadline. On paper it should be well over 1M which is many times what we have or intend to spend! We will do a detailed budget video at some point once we know ourselves. 👍
@@TheRestorationCouple Sorry, my misunderstanding as you mentioned solar panels I assumed you were just talking about electricity not hot water. Keep up the good work and I wish you and your mum to be all the best.
@@devilmaycare2809 ah sorry. Yes we had solar thermal on the plans but been designed out now to PV only I think. I put them in the design for the pool but been advised against by most who have run the figures. Still possible though.
@therestorationcouple : from experience in our own home, solar thermal seems to be many times more efficient than converting into electricity in terms of MW... also the "battery" ie water tank is so much cheaper and more efficient than installing normal batteries... Could you shed some light on why you were advised otherwise???
Have you consulted with an HVAC pro regarding your plans. These decisions at this point will result in years of pleasure or years of compensation for poor planning. One of the ill neglected areas of concern is how air circulates in and out of a home. A super insulated home does not always result in a comfortable or energy efficient home. Air must be exchanged in both cooling and heating and you certainly don't want to open a window to compensate for poor air exchange..
Hi Folks. Lot's more info later in the video covering most of the recent questions and comments on the roof. 👍 Enjoy!
I uused the same roof construction on my extension. I cut thr roof in for a close fit. There are fill in panels in the catalogue on Kingspan's website. Good job for a skilled fitter team.
Love the roof! But I came here to give a shout out to your perfectly popped collar! This 80s kid approves!
Currently looks like a new supermarket! Looking forward to see it turn into a house and your home. Love your channel!

Great point. We had them in my parents house growing up and they worked really well. Definitely worth thinking about. 👍
I concur. A number of friends houses here on the Canadian Tundra have solatubes, and I’m always shocked how much light comes down the pipe.
I had to comment and tell you what a beautiful job you are making of your new house you will all deserve it when it is finally finished, I bet you cannot wait,

Loving the work so far!
I think that roof looks really good. I would prefer that to tiles on a house.
I think the roof's great. Good job.
looks great
Watching all the remarkable work you have done, makes me wonder exactly what the planning commission was preserving. Footprint? Shadow?
Looking great, keep up the good work
Hi guys the roof looks well 👋
Always check your watch, when considering seasons ... 🤣

I got Velux with covers on the outside, good for night, rain and sun ... they are not cheap but really worth any penny ...
That's what has been specced. 👍. May try on the bedrooms first as they are at highest risk of overheating.
You will hear the rain on the roof. It transmits sound quite well. I imagine the internal structures will help dampen the sound though.
a job well done mate
Can you get the BiL to colour in the plan once a section has been completed? Slowly it'll be full colour as you progress!
Quick tip put a mesh round the solar panels to avoid birds nesting underneath them.
Cool 😎

Dont zone it. Properly ballanced and pure weather compensation should.get you closer to 500% with a well designed system.

Roof is insulated so no cold metal to condense on.

There is insulation above the timber and steelwork. Billy Basics

This channel has gone a long way from building a garden shed!😇
Just a bigger shed really! 😂
Are you considering light tubes for the rooms and spaces away from the perimeter?
Has the 150mm insulation exceeded your planning hieghts ??
No, we specified this roofing in our full app.
What sort of technology are you looking to include in the final build? You must have terabytes of footage for example, so are you considering including a server room? What about smart home products - are you considering audio or lighting? Or going “old fashioned” with regular lights and switches?
Yes there shall be switches for lights, and they will be called Light Switches
Will water blow up inder that ridge straight into your newly insulated ridge void?
Sorry, missed that bit. There are profiled seals along there under the cap which are weatherproof.
Can I ask why you never used this type of roofing on your log cabin build, as you had it on your house workshop. Cheers regards Steve
We have flat ceilings in most of it so was easier to just use loft insulation, plus the cabin had to be able to split in half so would need more engineering for ridge beams. Could have worked though.

Have you considered rain noise? How much sound insulation does that type of roof provide.
Covered it in the Q&A but not that much and less once new ceilings are up. This alone is 0.12.
Great roof ! I was just wondering if you considered solar thermal panels as they are a great way to save money.
Especially if the swimming pool happens, solar thermal panels will definitely help.

Yes we have the MVHR design already done.Will be a two stage install as it's multiple systems.
Are you going to use sealant on the underside of the joins?
Sealant where visible like above pool but will probably use an airtight tape on the main part of the roof.
Windows going in afterwards i presume?
