Questions & Answers

will Home Depot cut the item in pieces?

will Home Depot cut the item in pieces?
Asked by: JohnDoe
I asked and the answer was no, there was no offer to help me either. One staff member offered me his knife but need to keep the cut straight. I can get the 8ft length in my car but not the 4ft width. So just need it cut straight down the middle

Would this work to insulate a garage slab floor before installing a subfloor and hardwood on top?...

Would this work to insulate a garage slab floor before installing a subfloor and hardwood on top? I want to put down a 6mil vapor barrier, then a 1" layer of Foamular with 1/8" spacing and taped with 3/4" plywood glued to the top then hardwood floors over that. Is this the correct product for that application? If not what would you recommend?
Asked by: James
Yes, this product can be used for that application.

How can I "glue" this to another Insufoam XPS board? The ceiling already has XPS board and I want to add this pink one as well, on the bottom side. What adhesive will work to glue those suckers together, (giving me more R value)?. I can NOT remove the existing XPS. Remember that the existing XPS board is probably not porous.
Asked by: memorex
Not aware of any glue that won’t eat thru the foamular 150 You probably will have to mechanically fasten a board to the xps then glue the foamular to it Or mechanically fasten the foamular thru the xps to the substrate
