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.

is formulae i50 R-7.5 good for basements
Asked by: ayo
We used it in our new construction basement. We glued it directly to the concrete wall, then furred over it with 2 x 4 studs, then put R-11 insulation batts between the studs and then visqueen on top for a vapor barrier. I also cut pieces of the foam board to fit in between the floor joists around the top rim of the basement walls and stuffed R-19 insulation in front of that. We then blew in insulation between the floor joists. With the dirt backfill on the exterior our basement never gets below 55 degrees even when it's below zero outside.

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 168.

Easy to use, easy to break into narrower sheets to get into tight crawlspaces and easy to mount to a foundation wall (my use case). My only concern is that this isn't 1 inch thick, it's closer to 0.7-0.8" so you're losing 20-25% of the claimed R value right off the top. If you consider it an R-4, instead of R-5, sheet then it's probably fine.

They cut and paint easily and glue together using the recommended glue and wood skewers to hold them together. The 4 star rating rather than a 5 star was because the shelf was not fully stocked and I had to take a couple culls!

Very simple but effective. We have a French door in our bedroom that has rotted wood that we will have to replace the entire door window combination but simply cannot afford to do so yet. It lets in cold air so much so you can feel the draft. Two sheets of the OC Foamular 150 and problem fixed albeit temporarily.

I used this product as a vapor barrier and first layer of insulation on inside of my in ground basement walls. Product is lightweight and easy to use, cutting and shaping with a Stanley knife, then securing to the wall with foam board adhesive. Plan to use 1 1/2 or 2 inch versions for inside of my out of ground basement walls.

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 had to make a barrier against a very cold wind in a pinch when a very large limb broke off a tree and came right on through the window and siding during the latest storm in the area. Easy to cut and break to size and with new window in place I'll be using the foam board elswhere.

Bought it to insulate the crawl space under the entry stair landing on my raised ranch. It was always very cold on the landing even though it was insulated. It made a huge and immediate difference! Easy to score, cut and fit in place. I would definatley recommend this product.

Used a foam board adhesive to create a box to push up against the fountain. Works well, easy to work with and hopefully provides enough protection against temperatures in the teens at times.
