Rated 5 out of 5 by from Pool bottom I used it for under a above ground pool, it’s awesome, I tucktaped the joints and you can’t really feel the joints or see them once the water is in. The bottom is getting dented but it feels better then sand, for the cost I feel it was worth doing

Rated 5 out of 5 by from 1” Insulation Board - Rim joists Easy to cut and use, good price, used inside to put against outside wood between rim joists before adding R20 fibreglass and then vapour barrier. Works great.

Rated 5 out of 5 by from Above Ground Pool Base Solid and easy to use. I used this styrofoam board as a base for our above ground pool. It is solid enough to not ding or crush when standing on it. It also gives a soft, flar surface for your feet on the bottom. Also, it helps keep the heat from being pulled out by the ground.

Hi there, I'm looking to use this foam for base for an above ground swimming pool. How compressible is the styrofoam? Is it weather resistant? Do you believe this would be suitable for my application? Thank you

Asked by: Ed71
This is a 10PSI and does meet code for your application however I would recommend DurpFoam Plus or a 25 PSI product that you can special order through any pro desk.

Can this be used to insulate a cold cellar? I plan on using this to cover the top 4 feet of the walls and the entire ceiling of my cellar.

Asked by: Bobby
For sure, as it is the best way to stop condensation on cold surfaces but would recommend the 2" thick sheet. Also, do not use any plastic vapor barriers as it will trap moisture..

We are trying to insulate our tiny cottage to make it warmer for use in off-season- it's sitting on pillars. We are going to put in a new floor on top the old one. Can we put this product underneath the new vinyl flooring to help insulate it?

Asked by: mpm54
Hi you can use this for sure. We do however recommend that you strap the floor to add support. PDF instructions are attached to this product on homedepot.ca

will contact with a spray foam have a negative impact on the facing or foam of this product?

Asked by: Mike
You need to ensure that whatever spray foam insulation you use is foam safe. It will state this on the container.

Is this suitable for garage door insulation? Would it be better than DuroFoam of similar thickness?

Asked by: John B
I think it would be ok cuts very clean on the table saw. I have never done this myself but would think your spring would have to be adjusted for the extra weight.

My basement already has the wood stud installed. Can I install this between the stud? Do I need to install the vapor barrier?

Asked by: Silence
The product will act as a vapor barrier (< 1 perm) and you could put it between the studs but would still need a vapor barrier because of the studs themselves and all the joints between the foam and studs. I put mine overtop of the studs and taped the joints with tuck tape. I tightly fit pieces of foam between the floor joists above and caulked the joints with accoustial caulking. I held the foam in place by screwing 3/8 inch x 2 inch wide osb strips through the foam into the studs (do not overdrive the screws) and then glued and screwed the gypsum board to the strips of osb. Please be aware that this foam should be covered with thermal protection (gypsum board) when used on the interior of a residence - please check your local codes. Good luck
