Questions & Answers

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.

will Home Depot cut the item in pieces?
Asked by: JohnDoe
We know it's easy to cut, but I assume you are asking because you can't transport something 4'x8'. I have had wood, thin sheet plastic, plastic pipe, metal pipe and trim cut because it would not fit in my sedan. YES they cut everything.

I am planning to add this all around the basement concrete walls and then use the normal fiber glass insulation between the 2x4 studs to get the required R-Value. My question is do I use faced or unfaced fiber glass insulation between the studs?
Asked by: SPID
Faced insulation in the stud walls.

FOAMULAR 150 1 in. x 4 ft. x 8 ft. R-5 Scored Square Edge Rigid Foam Board Insulation Sheathing is rated 4.7 out of 5 by 187.
Rated 5 out of 5 by from Furnace plenum & return air. I used this to build a plenum and return air on a new 97% efficient air handler in Deep East TX. I cut all the pieces on a table saw and used styrofoam adhesive to assemble. Where it runs through the ceiling into the attic I wrapped with 2X6's for support. It is very sturdy and save me money.

I slid Foamular 150 between the studs and behind the existing 2x4 walls in my basement and adhered it to the concrete basement walls using Gorilla construction adhesive (only one I saw in the store specifically rated for both foam and concrete), and stuffed pieces of Roxul mineral wool between the studs and the Foamular to hold it in place until the adhesive dried, then filled the 1/2"-3/4" gaps between the Foamular slabs with Great Stuff Pro Gaps and Cracks. The Foamular 150 was flexible enough to slide in between the studs without breaking, and in combination with Roxul R-15 mineral wool between the studs supposedly gives me an effective R-value exceeding Washington State's R-21 requirement and a highly moisture-resistant assembly. Great for a 2x4-framed basement and a LOT cheaper than spray-foam. My family is REALLY happy with this insulation scheme, in combo with insulating the rim joists in our basement with Foamular-250 that is edge-sealed to the framing with Great Stuff Pro Gaps and Cracks!!!!

It is a solid core easy to cut and does not have the issue with flying foam particles. When cut it gives off much less 'dust' than even plywood.
