Questions & Answers

can this be used under a basement slab?

can this be used under a basement slab?
Asked by: crh
I would not suggest that.. This stuff is foam so it would have some foamy attributes like when you step on it, it squashes down but doesn't come back like a sponge would. It just compresses. So I would not recommend this for a floor at all.

I want to use it to insulate a wall on my shed, my question is do I place the foil paper side facing inside or facing Out? What is the correct way to use It? BTW, my wall won't have drywall installed on top of foam board
Asked by: Jaygeo2020
I don't know about a shed if it would matter. I use this in a north facing window to block light and cold with the silver side out. I have no problem with moisture and my room is dark and warm all winter. I work a graveyard shift so dark and warm is important. I would think with a shed it wouldn't matter but for the moisture issue. Good luck M. Ps this stuff is great and go with the high R value and make it work

When you cut it, Is this a crumbly type of foam or a high density one.

Asked by: JK
"superior closed-cell, lightweight and resilient expanded polystyrene...." as stated in the specifications online. I would not describe it is high density. It is appears as small white pieces adhered together and some do come loose when cutting but not anything significant when cutting with a sharp knife, such as a new disposable break-away utility knife using a sawing motion. Minimal loose pieces of the foam core detach when cutting and handling. Having cut many window size pieces to insulate single pane windows lightweight R-Tech has proved very good at not crumbling and remaining rigid.

Can it go on a window to keep a bedroom cool in hot AZ SUMMERS?

Asked by: Cathy
This R-Tech foam worked great to insulate windows. Much better than curtains or shades. Be sure to cut to shape precisely, so there are no gaps around the edges. If there are gaps, warm air from your home interior will leak in between the foam and the window and condense on the window when it is cold outside. If you frequently install and remove your foam window covers, they will erode along the edges. Adding a strip of adhesive tape long the edge of the foam provides a handle to pull the foam cover off of the window
