Can I pour 1.5" of concrete on top of this for my radiant heating system? There is a slab below this... I only have 3 inches total space and i'd like to keep my concrete a 1.5" thick slab.
Asked by: Spikes
Hello Spike, FOAMULAR 150 is designed for both under and over slab use as follows: For Under Floor Slabs, FOAMULAR 150 or 250 can be used for residential and light commercial applications where floors are subject to normal loads (use FOAMULAR 400, 600, or 1000 for industrial applications where floor areas will be exposed to heavy loads). Use gravel fill to establish a stable, even base. The gravel must be thoroughly tamped before installing insulation. Be sure to butt the insulation boards tightly together and against foundation walls or adjacent vertical insulation. But in your situation, over concrete slab floors, FOAMULAR rigid foam boards offer long-lasting thermal protection. It can be mounted directly over the concrete slab, and abutt the FOAMULAR wall insulation where it meets the floor. In specific with radiant heat - this is a great choice (see attached picture). I had a similar situation. I had a furnace plenum that was in my garage floor exiting into my basement. I didn't want this hot air plenum against the ground, so I made a box of 2" foam all the way around and pour concrete between the foam and ground with the duct nested inside the foam box. This keeps my heat in the duct and not running into the ground. Heat tries to go where it's not - which can be in any direction! So you would be wise to insulate below the radiant heat so it rises to the cold floor and not to the colder slab. Hope this helps. Jeff

Do you still need to use roll insulation along with this? looking to finish a basement. Or is just this board enough?
Asked by: jaxck
I am using this based on an experienced friend's recommendation. I am using rolls in the ceiling to the first floor (for sound as well as heat), but I am not using rolls for the walls that have these panels behind them. I think where the panels are located, that is enough.

will it repell bugs and mold ?

Asked by: susy
I am a consumer however if you call the technical dept. at Owens Corning they can give you the correct answer. The product is closed cell insulation and I used it as a vapor barrier against my concrete basement wall. It is not supposed to allow moisture and if you drop water on the product it beads up and does not absorb the water. Great stuff for my application.

FOAMULAR 150 1-1/2 in. x 4 ft. x 8 ft. R-7.5 Scored Squared Edge Rigid Foam Board Insulation Sheathing is rated 4.8 out of 5 by 105.

I used this to line my basement concrete walls before framing and finishing. I used this type because of its moisture barrier properties. I haven't finished the framing yet or tried a temperature comparison or anything like that, but I would recommend this for general insulation. It cuts and shapes easily and seems to create a good solid barrier. I used foil tape to block the seams which also helps seal it as a barrier. I have used it around a few windows that seemed to be leaking air and this insulation seems to have helped quite a bit. For general insulation, especially where a full barrier is needed and makes sense for your application, I would definitely recommend. I used some tables to hold the insulation tight against the wall while the liquid nails behind it dried.
