Insulating Crawlspace Walls

Because heat m.igrates to cold through the bottom of the house, an uninsulated crawlspace means you’ll use more energy to heat your home during winter and to cool it in summer. Insulate your crawlspace with Owens Corning® FOAMULAR®.

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

Asked by: ANVIL
Dear Anvil: I assume you are describing a basement upgrade. If so, yes, Foamular XPS foam board is the ideal solution. Here are some tips for insulation etc in a basement: (1) Make sure there are no cracks and leaks in the walls. Fill and seal cracks with Sikaflex Model # 7116110, Home Depot Internet #300934565 Store SKU #652010 If moisture is coming through the wall, apply damp-proofing to the surface. Products like Drylok can provide an important layer of moisture protection. See: Drylok Model # 28615, Home Depot Internet #202610896 Store SKU #1000531519. This product will minimize diffusion from the soil through the foundation. (2) Use Foamular XPS foam board. XPS does not absorb moisture; a 2" thick layer will provide R-10 insulation plus a strong vapor retarder. Foamular 150 or 250 are fine for walls. Use Foamular 250 on floors. (3) Using foam board compatible glue, fasten sheets of foam board to your concrete walls. Apply a thick bead around the perimeter of each sheet, to create an air seal when it is pressed against the concrete wall. See: Loctite PL300 Model # 1421941, Home Depot Internet #202020476 Store SKU #780400. You can lean a 2x4 against each sheet to hold it in place while the glue sets, or pin them in place with a RamSet. After all of the sheets of foam board are installed, seal all of the joints and edges to block air leaks. DAP 230 works well for joints and small gaps; the 'Window and Door' version of Great Stuff foam is good for larger gaps. (4) Build your new 2x interior wall in front of the foam board. Use pressure treated (PT) lumber for the sole plate. If water leaks could occur and the floor may be damp, install a piece of Veranda cellular PVC trim on the floor first, to lift the sole plate off the concrete and keep if from rotting; leave small gaps every few feet for water to trickle through under the DriCore panels noted below. Use a RamSet to drive nails into the concrete, or drill holes for expansion bolts. We use bolts in areas with high stress, e.g. near doorways, stair landings and the ends of pony walls. See: RamSet Model # 00022, Home Depot Internet #100091715 Store SKU #107708. Be sure to wear ear and eye protection when you use a RamSet. (5) Insulate and seal the rim joist pockets: Install 2" thick pieces of Foamular 250 in the pocket at the end of each floor joist -- to insulate and seal the rim joist. Seal the edges with the 'Window and Door' version of Great Stuff foam to block air leaks. Then fill the rest of the end of each bay with rock wool. (6) Run your electric lines to receptacles and lights. Fire block (seal) the holes in the studs with 3M Fire Block sealant. See: 3M Model # FB 136, Home Depot Internet #100390499 Store SKU #191728 DO NOT use any type of spray foam, even if it says "Fire Block" on the label, e.g. Great Stuff. These spray foam are actually very flammable. Informed building inspectors can fail an inspection if they find spray foam used for fire blocking. (7) Fill the stud bays with rock wool. See: Owens Corning Model # UB-40-P3D-15--47--121, Home Depot Internet #304633821 Store SKU #1003061505 (8) If there is any possibility of a water leak into your basement, install DriCore panels on the floor first. They have a rubber surface on the bottom with channels that water can trickle through. Make sure, of course, that you have a drain with a dry well or sump pump for the water to escape to. Carefully seal all of the joints and edges of the DriCore panels to block air / moisture leaks. Then install 1" of Foamular on top of the DriCore, and seal the joints and edges. Cover the Foamular with 3/4" plywood as the subfloor / nailbase for your new flooring. Run the plywood 90 degrees from the direction of the foam board, with a 1/2" gap around the edge for expansion. Again, seal all of the joints and edges. See: DriCore Model # CDGNUS750024024, Home Depot Internet #202268752 Store SKU #361018. We installed DriCore at a recent project as a fail-safe, even though the basement was dry. Water leaked in unexpectedly through a window during a downpour, and DriCore saved the new floor. If you are certain that there is no possibility of a water leak into your basement, install 1" thick Foamular on the concrete floor -- and seal the joints and edges. Cover this with 3/4" plywood, running 90 degrees to the foam board panels. Leave a 1/2" gap around the edge to allow for expansion. Again, seal all of the joints and edges. (9) Also read up on fire blocking, which many people overlook. This is required at the top of basement walls, along the walls, at the top of stairs, etc. Do a Google search for "How to Firestop Your Basement" from ContractorKurt. Roxul rock wool is a good solution. You can stuff it into the gap at the top of the wall and into the end of floor joist bays. To seal holes created for pipes and wiring, use fire resistant caulk, e.g. 3M Model # CP-25WB+, Home Depot Internet #100166701 Store SKU #163096.. DO NOT use the "Fireblock" version of Great Stuff foam; as noted above. I hope this is helpful. Mark
