Spray foam

[Diyisfun]

I have a small (6ft x 3ft) area under the stairs that is just brick.
It is a very cold area that is completely out of site & difficult to access I was thinking about using

Would this do the job?

They are really for gap filling and suchlike.....is there any chance of getting some slab insulation inside?

No. As Burnerman says, that's for gap filling. Though it could be used successfully to stick some foil-backed Celotex or Kingspan to the wall.

Are you living under the stairs.?

 

[Diyisfun]

Not living under the stairs, but due to the shape of the opening & a step inside with pipes underneath a door cannot be fitted & there is a lot of cold air that comes from the space, although we do have a curtain there.
As for putting a slab of insulation there, it wont be easy but will give it a think.
Thanks for your input.

jj, thanks for the link

Can you post some pictures of the problem space?

I think using professional foam equipment is going to be expensive, messy and potential hazardous, even with the correct PPE.

I don't need a pro..the cost will out way the saving.

I wasn't suggesting you would use a pro. Rather that it would be expensive, messy and potentially hazardous using that stuff yourself. I've done a lot of domestic insulation and I wouldn't use it. If you can get into the space, you could do a lot better with conventional insualtion materials, more easily, at significantly less cost.

Anyway, we'd be better able to make suggestions if we could see what you're dealing with.
