Insulating brick shed

[Tomzo47]

Hi all, we might be moving house soon and one we're looking at has a brick shed (old coal store) that id like to use as a bit of a workshop. I'd like to insulate it to make it bearable in the winter. Only problem is we're renting and likely to only stay for a couple of years, so whatever I do has to be cheap and removable when we leave. Any thoughts?

How big is it, Tomzo47? What's the roof made of? Pictures?

Hm, you'll have to balance heating cost with insulation cost.

Ceiling: 6x 12 1/2mm plasterboard ~£30, 6x 25mm EPS sheets ~£35.

So that's about £70 which equals (say) 500 units electricity equals (say) 40 days of 2x 2Kw fan heaters for three hours a day.

How much more do you want to do/spend?

Bung up gaps etc. Put something on the floor to keep your feet warm, I'd suggest getting used carpet off eBay or similar. Insulating the walls will be more expensive unless you go for a nasty bodge like bubble wrap with hardboard over.

[Tomzo47]

Thanks mate, the cheaper the better as it's only a short term thing. If we were planning on staying for longer I'd do the job properly. If I could get away with spending about £100 On materials I'd be happy. Current thoughts are timber batons on the walls and ceiling with chipboard instead of plaster board, filled with Rockwool. Not sure about damp control there though. Also know that's going to be well above budget, but not sure what else to use.

Battens/rockwool/chipboard might put you rather over budget unless you know somewhere really cheap/2-hand, what have you costed that at? Possibly use thinner EPS, 1000x500x10mm external wall insulation, overboard with hardboard? Lots of options....

Hang rugs on the walls, wear Merino wool thermals and socks.

For a couple of years. Heat it and be dammed.

The equation is determined by the cost of heating versus the cost to keep the heat in.
Sometimes the return on the investments take several years to be realised.
Two years is nothing if the cost of what you need to keep the heat in is properly considered.

Plywood is more expensive that Gyproc.

How long are you really going to be in there, for a small space a fan heater or halogen style heater will be ample for a couple of hours vwithout insulating it.
The only thing is with no insulation it likely won't be frostproof so watch your tins of paint or whatever

If it's single skin brick, it could be quite damp. I'd be more worried about keeping it dry than warm. My conservatory has brick pillars with no cavity. One is SW facing and damp wicks through it over the winter.

You can paint a waterproof liquid on the bricks which helps. If the roof is letting water through, just stick a sheet of EPDM over the felt as a temporary fix. It's about £7 a square metre.

If you do want to insulate the walls, maybe some Celotex sheets would be cheap and easy?

You'll be wanting a job on a construction site then! I used about £150 worth of Celotex or equivalent in my shed build, and I only paid for £50 worth delivered.

Its the double thickness bubble wrap foil lined on both sides that I'd like to find a cheap source for. That stuff is silly expensive but so damn useful anywhere really.

I would invest in a very good space heater and forget about doing anything to the walls if you are only going to be there 2 winters.

Buy one second hand and than flog it on when you move. You'll probably get you money back as a bonus.

Its not a very big shed and insulation takes up space. Space that would be better used by a bigger lathe. Heated insoles and perhaps heated floor would be my suggestions.

What are you using shed for? I need to have the door open when Im using the lathe, it makes plenty of oil fumes, then any kind of room heating or insulation becomes pointless,

[RhynoCZ]

Buy a nice coat. I would need some pictures and more info. Many times people start with insulating the walls, roof etc., to only end up with a damp shed (house) with condensation dripping from the ceiling/roof.

Heating a brick workshop is all well and good but if you're going to put any machine tools in there then they are going to rust if the shed is very thermally inefficient. Far more so if it has a tin roof.

I'd find a way to insulate it, even if it was just rockwool, battens and hardboard.

In Bristol there is a wood recycling project. If you have something like that, you might be able to reduce the cost. (they give pallets for free)
So you could potentially batten it for free. You could even cover it with the wider boards so free if you can joint the edges. Then you could spend your budget on kingspan / rockwooll / screws / plugs.
I wonder if you could fill the void with sawdust? Might be a bit fire risky.
Doing the same on the floor and covering it in carpet (off cuts or free to collector from gumtree), it will help it feel warmer too. (depending on use)
Having some sort of timber walls will make hanging tools and nudie pics easier

[Tomzo47]

Had another look last night, I don’t think there’s enough room to dry line, so would have to look at other options. Weirdly it was rather warm in there so might not be too much of a challenge…. Bit of damp on the walls so my current thoughts are paint on a DPC and give it a fresh coat of paint, have a little fan heater and maybe a dehumidifier (although running this might be ridiculously expensive).
