Phil well done on build, respect for your innovation and recycling.
Inspiring and interesting. Thanks for sharing
Thank you for watching Nyali 🙂
I like your style of explaining things. Down to earth.
Thanks very much
Awesome i’m definitely going to consider that plan and thank you for sharing and taking the time to do so 👍
You are very welcome 😁
Very nice. I'm storing a lithium ebike in a plastic shed and need to keep it cool in the summer. Using rigid styrofoam and aluminum boards double sided taped and spray foam insulaltion in the gaps. Aluminum facing out. We'll see how it goes.
@@vincent.416 interesting 🤔 let me know how that goes as I haven't tried insulating a plastic shed.
@@PhillWyattProjects I'll let you know in a few days 👍
I am a novice and insulating my garden office tomorrow Phill - absolutely brilliant video, thank you. :)
Thanks very much 👍🏻 good luck 👍🏻
I just found this vidio, very helpful, I just planing on doing my shed up in the new year, the only thing is, it's a brick shed, so ya, looking at everything I can to make it warm and dry. I'm now going to look on you sight to see what eles you have.
Thanks Juliana🙂
Good video pal .. going to watch how you built it now 🙂👍
thanks mate!
Great info . Thank you
No problem 👍
You stole a bus stop 😂
I actually found that window 15 years ago and carried it home with the intention of using it one day
Great info, I’ve only just discovered these. Did you also board the ceiling too?
Thanks! I have started to board the walls. Haven't got round to the ceiling as yet though.
Hi Phill, it’s so good to find your this video, as I’m wondering 💭 how can I insulate my Shed/Workshop/Man-Cave. My Shed is same as yours (16’x8’) with concrete floor and Apex Roof. Any advice would be greatly appreciated! How many of these Rolls you had to get for your Workshop/Shed/Man-cave? What exactly you put inside the ceiling before you stick those Silver Bubble Wraps/Insulation? It would cost me £1,400 if those guys are building my Shed, which is way over my budget. It will be hard because I’m disabled, but I’ve to do it myself if I’ve to save that kind of money ££££.

4.45 mins in how good are those little plug in heaters ? Worth buying
Great video, building my first shed /workshop this year . It’s being built straight onto decking . It’s a 12x5 pent . Any advice on what to do regarding the bottom frame to fit the flooring to . Am I best to have a good 4” gap between the shed floor and the decking . Also any advice regarding floor insulation. Cheers ( advice welcome from viewers as well 👍🏻 )
Thanks 👍 an air gap is a good idea for ventilation. I think 4" would be fine. For insulation, I would suggest to use polystyrene insulation boards then cut them to fit in between the floor framing.
I've used this bubble wrap stuff but on the roof i put it straight to the beams not actually the inside then player boarded starighht to it leave a big gap behind i am getting damp in now have i done this wrong ?
Fantastic video just sorting my shed out, I’ve bought the therma wrap foil before I board it out would a layer of loft insulation make it even better or not much difference?
Thanks 👍 yes I think an extra layer of loft insulation would certainly make a difference. Similar to adding an extra layer of clothing.
Hi Phil just seen you video brilliant by the way. I ve got a metal work shed 10x6 for my tools, kit and a work bench for my little job etc. The bubble foil insolation looks just the job only problem I have a sliding double door so there will be a draft issue semi sorted by using old double glazing beading along the edges also thinking of making a strutt frame on the inside to eventually board over to as you said fix tools ect any suggestions or ideas mate
Thanks Chris👍 that all sounds like a good idea. Any ways of stopping drafts makes a significant difference. Maybe double up on the aluminium bubble wrap or use polystyrene on the metal walls and roof to prevent condensation. I made a video recently about the same topic and now I have started boarding out the walls with scrap sheet materials.
Hi Phill
Great job on the shed.
When you fixed the bubble wrap insulation to the walls and celling do you just staple them straight onto the sides or did you put another bit of timber framing in like you did when you put the boards over so it had another air gap?
As I’ve seen another shed video where they have just stapled the wrap straight onto the shed panels.
Thanks Ads
I stapled the wrap onto the panels. This worked well for me. Feather edge,wrap,then bubble wrap. There are various ways it can be done. My main air gap is between the inner board and the bubble wrap which seems to work well.
Is there a video on the wrap you used ? I really need to install something similar in my converted shed to room project
No but it was a 3 layer wrap. There are several brands available.
Thanks Phil. I am about to build a workshop and I have learnt a lot from your video. I want the build to be insulated AND sound proofed both being contained both within depth of the framing (either 3 or4 ins). So I plan to place in my walls/roof sound some Insulation slabs (like Rockwool) on top of the bubble wrap. Will having the slab layered on top affect the the insulation performance of the bubble wrap at all?
Thanks Ray. In my opinion if you use Rockwool, then I probably wouldn't bother with the bubble wrap as the Rockwool should be sufficient enough. If you do use the bobble wrap, I don't see why it could cause any problems. The air is sealed inside the bubbles so it maintains its form.
@@PhillWyattProjects Thanks Phil. Sorry, I don't think I explained clearly that it would be acoustic Rockwall slabs but your explanation of the sealed air in the bubble wrap would I think answer my question.
Hi Phil, thanks for the video.
I need to insulate my shed/workshop and I'm going to buy some Superfoil. In some of your video footage, it looks as though the insulation on the walls has been fastened but without using the foil tape too. That's actually what I was planning on doing and just wanted to check if I really need to buy the tape too? I would eventually fit plywood over the top. Cheers, Andy.
That's correct Andy I haven't used it to apply the foil bubble wrap. The reason being that the shed already has a breathable membrane which has been sealed with aluminium tape. So I don't see a need to seal it again. If your shed doesn't have a breathable membrane already on it, then it might be worth using it. You can pick up a roll of aluminium tape cheaply online and they go quite far. Useful stuff.
@@PhillWyattProjects That's good to know and thanks for replying so quickly. I'm keen to get the stuff ordered as the shed is baking hot at the moment! 🔥
Great video, impressive work you've done on that shed! I have just bought mine which is 20ft x 12ft and the floor is made of four panels just sliding in together (and they're of course lying on base beams sort of) but now I am not sure how to prevent the condensation from occurring. I will do the walls and ceiling the same way you did but do you have any recommendation when it comes to the floor since I don't have any insulation underneath, it's just a concrete base and straight on it the floor on a bit of elevation. Do you think just laying a plastic membrane and vinyl flooring on it would do the trick? I hope you will find some time to answer my question, it would be much appreciated :) thanks!
Hi sorry just noticed your message. Laying down a membrane under the vinyl would certainly help I think. Another thing is to insulate and possibly board out the roof as this is where the warm air will rise to and hit. If the roof is cold and uninsulated then it can reach the dew point and feel moist in the colder weather. Hope this helps
Exactly where I am at the moment Paula what did you end up doing ?. TIA
I built my Mad cave insulated the walls used a breathable membrane all round the outside under the cladding but i didnt put it under the osb sheets on the roof (layer of roofing felt then a double layer of pond liner on top of that) on the outside my Question is could i add the foil insulation to the shed roof in the same way as you have in this video without any problems ?? Its pretty chilly at times in winter in there lol
I'm not sure what your exact set up is for the building although it seems to be working fine for me at the moment. The shed has been up 3 years now with no damp or mould so far. Using insulation such as bubble wrap or polystyrene on the ceiling should help to lower the surface temperature of the ceiling therefore preventing dew from forming on the surface. If a ceiling is cold to the touch, it can form dew when the warm air rises up and hits it.
Hi mate how did it fare in the cold of winter? Thinking of using the same stuff on my shed but I want to be sure it’s warm enough 👍
The bubble wrap is fairly good but I think because I wrapped it with the membrane and sealed up all the seems with aluminium tape this really boosted it's effectiveness because it made the shed draft proof. Draft is a big problem in winter so that's the first thing to eradicate.
Great vid!!....what thermal wrap you used?...as too manny out there?cheers
I just used a generic one. They are all very similar. Any aluminium bubble wrap is probably fine. I just shopped around.
Nice video!
I ve got a metal shed with uneven surface walls and want to apply bubble wrap insulation. How do i do it? Just silicone it on the metal walls ? I can t use nails or clips?!? How do i go about this?
You could use a solvent free grab adhesive. Or you could buy the version of aluminium insulation which is designed for vans to dampen sound. This has it's own adhesive backing. You can find it online.
Hi mate do you think It would be ok to use this insulation on a concrete floor before putting carpet over the top of it.
Going to damp proof the concrete floor before hand tho with either a sheet of it or painted black Jack.
Cheers
Hi Adam, I think it might be better to use a kind of underlay. It is similar to this, but instead of bubbles it is like aluminium foil with a spongy foam. If you have a look on my video list I did one about insulation my loft hatch. In that video I use the stuff I'm talking about. It can be used as an underlay for laminate flooring and has insulation properties.
Iv got 12ft by 8ft and looking to get it all insulated and then start making my work bench in there
That sounds like a plan 👍
Great job on the build mate!
I have a 20x10 wooden shed with apex roof, which I used for storage and as a part time workshop. I am having problems with moisture in the shed causing mold and condensation on the items being stored (not the shed itself). I haven't done anything to the shed as yet, but I need to tackle this issue! I'm not sure what I need to do though... Do I need to make it as air tight as possible? or should I allow it to vent through the eaves gaps? Should I block up my eaves and install an extractor fan? Any advice/help would be greatly appreciated. Thanks in advance
Thanks👍 I would suggest providing adequate ventilation to allow the rising warm air in the evenings to escape. Add some vents around head height. If your floor is not sealed underneath with say a layer of damp course then you will always have warm air rising up through the floor. So the easiest way to prevent condensation would be good ventilation. This would be my first step advice.
@@PhillWyattProjects thanks for the reply. my concrete base has a damp proof membrane under the slab, that should stop moisture rising up through the floor. In one of your videos, you said you boxed off your eaves... is there a reason for this?
My eaves have gaps down both lengths of the sidewalls, is this not for ventilation purposes? Appreciate the help 👍
Good video mate,
What is the membrane called and the bubble wrap insulation, also where did you buy them? I want something like this for my workshop. Thanks
Hi, the membrane is called Cromar Vent 3. I got this from eBay. The foil bubble wrap was also from eBay you can find it there. Cheers👍
@@PhillWyattProjects thanks
Hi Phill. Hope you keeping safe and well. Just wondering where did you purchase the bubble wrap please. All the best, Ian
Hi Ian I'm good thanks 👍🏻 I bought mine on eBay I think although you can get it from many different sites online. I think they sell it in Wickes too.
upvc does expand
Slightly although nothing in comparison to wood.
Mine still getting moisture after covering the walls idk what to do ?
You might need to add some ventilation to allow warm air to circulate and exit the space.
nice build just a question you said about the damp course im laying aa 16x8ft wood shed on a concrete base how do i put a damp couse down is it the tape stuff and do i put it under the wood floor
I prefer to put it under the floor. If you do you just need to make sure rain can't get to it so that it doesn't act like a giant rain catcher. If you put it over the floor frame then add the flooring on top that should be fine it worked for me. You can staple it to the wood. The tape is not essential.
thank you for that info cant wait to get my man cave up
whats the music in the background? Nice workshop too :)
Thanks. Sorry I have no idea what the name of the track is although you can find it somewhere on the free RUclips music library.
Yo Phil, ive started taping my shed and where the sun hits the alu tape is pealing in the heat (south facing). Any other tape you would recommend or expanding foam was another option. Thanks for your info here, going to be my art studio and so thinking i may look for some bulkier 2nd hand insulation perhaps. May try the bubble wrap for this winter however!
Hi Kyle, yea when it's exported it does start to peel. Not much you can do about it apart from covering it over I think. Mine peeled until I covered it with the feather board. If you can get the thick insulation second hand that might be a good idea it's good stuff.
@@PhillWyattProjects thanks Phil! What do you mean exported? Im up on the Moray coast in Scotland so thinking cold and damp may get intense. Just moved house to this place with a pre existing garden shed, so this is to seal an old shed up.
Phil here Phil can I ask you if you stapled the Thermawrap insulation roll directly on to the shed wall or would it be better to have another protective layer first. I thought about weed fabric control directly on to it first then the insulation thermal wrap on top then board over the wall studs if you know what I mean. I look forward to your reply it all looks great you done a great job I hope that mine turns out likewise. Cheers. 🏴
Hi Phil, yea you could always add an extra layer although it might not be so breathable then. If you have adequate ventilation then that should be fine. I wish I had added another layer to my roof although everything is fine after 2 years now.
@@PhillWyattProjects that’s great mate thanks for replying I’m going to buy one of the trickle vents and instal one on the top area as you directed a good idea and I’ll leave the existing shed door until I can source a pvc one with glass. Thanks again Phil 🏴
I have a 3 car garage here in USA california. It's my man cave. Have a game room and my gym inthere. I insulated the walls, ceiling and doors too. I will install a minisplit system but before I do that I would like to know if I need so seal all gaps between garage doors and the door that goes out to yard. Somebody told me a long time ago not to seal it completely because the water heater in garage or something like that. I just want to be able to keep heat and cool in here. In summer time it gets up to 110 Degrees farengiht and in the winter time the coldest it gets is about 34 degrees farengiht
You might not want to completely seal it up to allow some decent air flow. It sounds like a large space so I would be more concerned with how you can heat it. Do you currently have any form of heating in there?
@@PhillWyattProjects thank u for yoir reply:) no I do not have anything in there. Is just well insulated...like I mentioned before I wanna add a minisplit unit that does both heats and cools
What has been the coldest winter outside temp and the temp inside w/ o a heater?
Well so far I think the coldest has been about minus 5 but that's a guess. Inside, it continually gets warmer the longer the heater is on. So it depends how long I'm in there for really
Hi, Nice Job!
Is it possible to just insulate the walls with the foil and keep it like that (no panels over it)? Or is it dangerous?
I want to turn my small shed into a mancave/pub to watch sports, play darts and drink some beers with friends. But I am not a DIY talent and also dont want to spend too much money.
There will be only older and second hand stuff in it.
Thanks for the advice!
Thanks Frank👍 you can leave it as I have for the past year with no problem. I am now panelling it just to add tools to the walls. It is not strictly necessary to panel over it.
@@PhillWyattProjects Thanks!
I have one other question. Maybe you have a suggestion. In the shed there is a floor with concrete tiles (its also the foundation of the shed). I want to insulate it some how without building a new floor over it. Is there some foil or sail that I can just pull over it that will insulate a bit?
will this help keep shed cool in summer?
In my opinion, it does but only if you make an effort to cover any windows as the sun light coming through the windows in summer will heat up the shed and the insulation will then hold it inside the shed for longer. Blinds on the windows could help.
Hi, what did you use to seal the gaps between the floor boards? Thanks
Hi I used an acrylic based gutter seal. Then directly underneath the floorboards there is a damp proof course sheet.
@@PhillWyattProjects Great idea - thanks will do that.
Are you going to add anymore insurlation on the walls? If so what will you use?
Hi
I don't think I will put more if anything I might board over the top.
@@PhillWyattProjects has it been warm enough with just the foil bubble wrap?
@@ryanedgeworth3966 it's been fine I just seat it the same as I would inside a room in the house. It holds the heat a d there's no drafts at all
Can that. Insulate be reversed to keep things cool? Needing help in florida
It's silver on both sides so I think it works the same either way around.
Hi mate, could you tell me what wrap did you use ? Thanks
Hi yea it's called cromar vent 3
Phill Wyatt Outdoors thank you, can i use these to insulate my garden shed? So it will stay warm during cold weather here in canada
Just been in my shed for the 1st time in a week to find frost on the inside roof how can I fix the problem
The frost on the inside of the roof may be caused by warm air rising through the floor during the evening and then condensing on the cold surface of the roof. I would start by adding sheets of polystyrene insulation to the roof sticking them in with an instant grab adhesive. This should help to insulate the roof and reduce the level of warm air condensing onto it. Also I would suggest adding an air vent up near the roof to allow warm air to escape out of the building at night when it rises up.
I bought this foil and have had a sensor going for 4-5 days now showing before/after being basically the same. I've not boarded over yet, but everything I've found has said that double foil bubble wrap is a "scam", certainly the data logger is showing it's having basically no effect.
Did you go on to also add celotex to your workshop? How's it holding up now?
I have not used celotex. I wouldn't say that the bubble wrap is one of the best solutions but it may be the cheapest. I do not agree that it is a scam. It has its uses and for me it has made a difference. It does depend on your set up also.
@@PhillWyattProjects My setup is a 2x2m shed with shipclap cladding and 30mm framework on the inside. I wanted to insulate it and this video was one of the ones that took me in the direction of the double foil bubble wrap. I did expect some difference, but the charts are basically the same unfortunately. There are some small gaps in the door where it's warped and in the single-gazed window, but not massively.
I think if I had the chance to do it again, and had the budget I'd get the 25mm foil-backed PU/PIR - but it would take 2x 35GBP sheets per side (3 sides plus roof, plus doors), and the same again on the roof, so works out a lot more expensive.
Have you noticed that your setup is insulating and retaining heat?
Foil helps to reflect infra red ie radiant heat. Double foil bubble wrap has very little conventional insulation for convected heat, which is needed. You need thicker insulation for that, 25mm solid insulation or glass wool, but make sure the glass wool is protected from the condensation which will form on the cold wall behind it, as when insulation gets wet it loses its insulation value. You need a vapour barrier which can be as simple as plastic sheeting on inside of insulation layer and tape it at all joins to prevent as far as possible the humid air getting in to condense on the cold face. Ordinary packaging bubble wrap could provide some insulation very cheaply, say 2 layers with the bubbles facing each other.
Have you got a link to the 3 part thermal wrap please?
Hi sorry I don't but it's called cramar vent 3. Check on Google
@@PhillWyattProjects thanks
I'm getting condensation on the inside of my wood panels of my shed. If I do this would it stop the condensation? I'm worried that if it will still condensate this will make it a bigger issue because now the water will be in between the wood panels and the insulation and stay wet for a longer time
It depends, do you have ventilation in your shed? Do you have any leaks? and what kind of base is your shed on?
@@PhillWyattProjects I don't have any ventilation, it's pretty sealed, but Im sure I have some air leakage if that's what your referring to, and it's sitting on a few cinder blocks, so it's not touching the geound
@@sakomardirosian3439 I recommend to install a vent towards the roof area near head height.
@@PhillWyattProjects I did double layer of insulation and it seemed to fix the issue. One layer of the r13 and on top of that added a half inch foam board
How did you ventilate it
For ventilation, I have a window that opens. Also, I have another window which has a trickle vent in it which is always open.
me again where did you get your bubble wrap from
I got it from eBay although I have also seen it in Wickes
Does this keep the temperature down in the summer?
Yes it does help to control the temperate although the main factor in summer is the amount of Windows. I have many windows that creates a green house effect. If you have less windows then it is much more effective at deflecting the heat from the sun.
@@PhillWyattProjects thanks for responding man
plastic does expand and contract
I suppose but not much when compared to wood.
The aluminum bubble wrap will help to reduce the sound when using power tools
That's also a benefit it's a win win 👍

I've got a 20ft x 12ft timber workshop...done loads to it ....getting mould problems and cannot use it or go in there now. I've had several ppl out who claimed they could sort it or find the cause ...absolute jokers.
Its been a money pit and just taken away the excitement...its now the brain of my life ... and from what I've understood and what you've basically confirmed is a condensation problem... HELP 😬😩
Where are you in the country??
Hi I'm in the Midlands. Do you have a damp course under your floor or vapour barrier or any kind of insulation? Also, have you tried installing a vent?
@@PhillWyattProjects have you apart from youtube somewhere i can contact you? Facebook??
@@PhillWyattProjects I'm in Reading ... want to go through what I've done and how i built mine then maybe you can advise. Already seen a couple of things on your videos i need to do.
I built the base ....scalpings whacked down , rebar etc ..7-8" of concrete BUT forgot DPM 🙈 ...theres a 1 brick later of engineering bricks around the circumference of the workshop which were painted with 2 coarse of bitumen and before sitting the panels on the put a DPM covering the bricks even though they had 2 coats of bitumen. ...had to seal the floor with concrete dustproofer bc the concrete company were a joke so it was a bit porous ( created a fair bit of dust ) ... roof was 12mm structural ply sealed between each panel with GB pro silicone sealant as were each of the structural panels. On top of the 12mm structural ply i put a fair bit of bitumen then laid polyester lined felt ( overlapping by 5" and plenty of bitumen between the overlaps....then a metal box profile roof was put on ....
Internal walls had a DP membrane put on from the company I bought the workshop from but i preserved the outside and back of the panels with Premier Q wood stain / preserve...it did coat a lot of the panel DP membrane but I've been told should affect it??
Walls inside were then insulated with 50mm polystyrene sheets leaving approximately 15-20mm between the outside cladding and foam insulation then boarded inside with 6mm structural ply.
No vents were added at this time. That winter whole workshop inside was black mould ..under ceiling and walls ....added vents now andits just on the ceiling boards ( not the 12mm structural ply roof as I put a ceiling up with a void between the 2 if that makes sense? ..there are 2 x 76mm round vents either end of the workshop to air the roof space void . ) ...so basically only thing on the floor concrete is the floor dustproofer sealant which isn't damp proof .. just stops dust kicking up.
I do have the bubble foil coated insulation under the perlings just under the 6mm ply ceiling boards ... doing my head mate.
I'm on hoarders next week ..,you should see the bungalow 🤪😂 lawnmower ..tools everything
@@martynj-c4965 If it still getting cold and damp with the air in the winter then it will always accumulate mould...maybe put one of those greenhouse bar heaters on a thermostat on about 5 degrees to take the chill out the air....if its insulated well enough. Refit the floor with some barrier underneath too and exclude all draughts.
@@martynj-c4965 if u could check the roof and see if the bitumens still wet, if it is thats ur issue i reckon
