Howya Des, AKA 21st Century Caveman. I'll start with me purchasing two sheds in Jan 2020, pre Covid. One is 20'x10' and the other is 14'x10'. We only got round to putting insulation in over the last few weeks. My son and I have finished the large shed known as The Den where only Super Heros are welcome "Your welcome!" I am almost finished my shed AKA The Bunker. All this is down to your videos on the subject, which gave me the confidence to take on such a massive task. Thanks very much for all the help! My son loves his Den for computer gaming and I just don't seem to be able to leave The Bunker without feeling hard done by. There were lots of mistakes made and a lot of cursing to booth. However, just like life with all its up and downs we got there in the end. A very big THANK YOU again from Ireland

Hi Des, These videos are great, watched the series a couple of times now! I'm actually buying my garden building (summer house) to save on some time. But I plan to insulate and board it myself. I was hoping you could advise on the best way to protect the insulation from moisture.. Basically the frame will be cladded in 22mm Tanalised wood. No OSB and no outer cladding. So that would rule out installing the outer breathable membrane. But where you've protected the insulation from moisture on the inside with the waterproof sheet, what would be the best approach to take to protect it on the other-side (against the cladding)? Thanks in advance for any help you can provide! Liam

@21stcenturycaveman332 жыл бұрын
Hiya buddy and appreciate you dropping by. I think there's 2 ways of looking at the ceiling lining issue. The problem with your suggestion is this. Warm air rises and condenses on a colder surface (i.e. the ceiling). Obviously the ceiling slopes at a good angle. If you line the ceiling first so you can tuck the plastic behind the wall lining then what happens to any moisture that has built up and drains off? It will seep BEHIND the plastic sheet on the wall and soak into the insulation which it is supposed to be protecting, thereby defeating the purpose of lining it in the first place. See what I mean? Best wishes mate, Des

I think you were thinking of the fiberglass insulation, which was a nightmare for itchyness; what you have there is like Rockwool, which is quite inert. Still wise to use a mask and eye protection though. I am sure you will be glad yo did the insulation down the line. For the summer as well as winter. Doing a section and swapping to another thing can help ease the boredom. I'm reading a Dexter book at the moment, lol.

I picked up some "YBS AIRTEC DOUBLE REFLECTIVE FOIL INSULATION" from Toolstation for my shed, but now that it's fitted, the temperature logger is effectively showing the same reading as without it on.

Great video. I'm doing a similar build myself! I have question though. It looks like you've got a cold roof but with no ventilation above the insulation. I was lead to believe that I needed around 50mm of ventilation above the ceiling insulation, even with a vapour barrier in, as some moisture will likely still get through somewhere. Just out of curiosity, what have you done to get around this?

Use insulation board so that it can be pushed up tight to the osb , there should be no where for the condensation to then form. Using the insulation type in the video will 100% cause condensation and won’t last.
@TheGlitchy333 жыл бұрын
It's a valid concern and one I' m struggling with on my shed build. Cold roof needs min 50mm uninterrupted airflow across the top of the ceiling insulation and the plastic shed (vapour control layer) needs to be completely and absolutely airtight. Staples, nails and screws through the OSB and plastic sheet compromise the barrier and moisture will condense on the underside of your roof OSB. I have to put sizeable holes in noggins to allow end to end airflow between rafters. Yes, it's only a shed but when you build to this level (I've gone to the expense of EPDM roof) a badly designed or badly installed cold roof might not last long.

Hi Des, need abit of advice of you if you don't mind. I've just insulationed my shed and am in mixed minds with barrier to go for? Is it better to do go with the black barrier like yours or the vapour barrier like out side? I've had a look online on I can only find a breathable one from wicks or should I just get the visqueen roll like yours? Any advice would be much appreciated thanks
@21stcenturycaveman333 жыл бұрын
Hi there, no problem at all. If you've insulated your shed (especially if you've used loft insulation like I did) then you definitely need a completely waterproof barrier such as the one I used. They're readily available at Wickes but not always that easy to identify on a basic search of their website. Here's a link to the one I bought: www.wickes.co.uk/Wickes-1000-Gauge-Black-Damp-Proof-Membrane---4-x-12-5m/p/152859 Please read all the questions and my replies to similar queries in the comments sections below the vid for explanations. If you install a similar / same) breathable vapour barrier as you put on the outside this will not work as moisture will eventually seep into the insulated cavities leading to damp, mould and eventual deterioration, etc. TBH, I think it depends on how much time and money you've invested in your project. If this is considerable and you want your shed to last for a very long time then you need to follow above guidance. I hope this doesn't sound arrogant but I am very confident about this. However, if your time and expense is minimal then if you've got some vapour barrier left then it's obviously better than nothing at all and will prolong the life of your shed but it will not last anything like as long as the waterproof sheet referred to above. Hope this helps, Des

Aha. This will actually be fine. This vapour barrier is NOT breathable and will therefore be perfect. But, it is half the thickness as the one I recommended and will therefore tear much easier. However, it is also one third of the price. My external vapour barrier was waterproof AND breathable - that's the difference. Buy whichever gives you best value for money my friend.

Des, ive been watching all these videos religiously as I’m going to be renovating my 8 x 6 shed to give it an update. Main question I need answering is, how can I locate the floor base joist beams? The shed was erected previously to me buying property, it’s definitely a wooden frame it’s on but for laying some fresh OSB boards to strengthen he flooring I’ll need to know: A) Which way the base frame joists run B) How many there is in total Obviously need to know where the joist/beams are so I can have sufficient screw grip/anchor point. Any advice wouldn’t be greatly appreciated buddy
@21stcenturycaveman333 жыл бұрын
Hi there buddy. Good to hear from you my friend. Assuming the ENDS of the floor joists aren't visible from underneath & outside the shed, I'd definitely use a magnet to identify where the nail / screw heads are. Mark accordingly. You may be able to scratch away the tops of them to expose them. Once you've marked as many as you can find this should give you a clearer picture as to where the joists are and which way they run. If you're still uncertain, it may be an idea to use a cheap circular saw bit (no more than 25mm dia / inch) and drill a hole an inch or so to the side of the nail / screw head to see whether you can detect the edge of the joist. This should also be wide enough to poke your finger through to check if still unsure. You may need to do this 2 or 3 times to determine how wide the joists are in order to better gauge how much of an anchor pint they will give you (particularly where boards butt together). Hope this makes sense and helps. Best wishes to you and yours, Des

Line inside of shed with waterproof plastic sheet to protect insulation from any moisture / water vapour 4. Mark position of all timbers so you know where to fix sheets so you can line internally 5. Line with boards 6. Put the kettle on and make yourself a nice cuppa ;?) Good luck, Hope this helps, Des

Hiya Stan. No buddy. The reason for the vapour barrier on the outside is to waterproof the building but also to allow it to breathe, thus reducing likelihood of rot. Conversely, however, on the inside, you need a completely waterproof membrane such as a thick plastic sheet to stop moisture penetrating into the insulation and timbers. Therefore, internally you do NOT want to fix a breathable membrane. Hope that helps Stan.
