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®.

Questions & Answers

Can this be used for the undersidee of a roof in a garage converted for living space?

Asked by: Troy
Dear Troy: Yes, although polyisocyanurate foam board will be more effective in this temperature range. See: DOW Super Tuff-R Model # 99060464, Internet #300528092, Store SKU #1002215973 Also carefully seal all of the joints and edges to block air leaks. DAP 230 or HVAC mastic work well on joints and small gaps. Use the 'Window and Door' version of Great Stuff spray foam for larger gaps. Then install 1/2" drywall over the foam board as your new ceiling surface. (This is also required; foam board is flammable and must be covered with an approved 'thermal shield' in any living space. The standard is 1/2" drywall.) If you live in an area with hot summers and/or cold winters, it would also be a good idea to start by filling the joist bays with rock wool before you install the foam board. Rock wool is much denser than fiberglass and delivers R-4.1 per inch of thickness. Versions are available to match 6" or 8" joists. For example see: Owens Corning Thermafiber Model # UB-40-P5D-15--47--121, Internet #303425926, Store SKU #1002951851. Hold the batts in the joist bays with Simpson insulation wire, which is available for 16" and 24" joist spacing. See: Simpson Model # IS16-R100, Internet #100375163, Store SKU #594333 Then install the foam board. I hope this is helpful. Mark

Where can I find this product?

My husband has been looking everywhere for this product. The website says it is "In Store Only" but it is not available within 100 miles from any zip code I enter - and I have entered codes out of state. Please let me know how this can be ordered for our basement project, or if another similar product has replaced this. Thank you in advance.
Asked by: rgonz
i contacted the representative at my local home depot pro desk. They did not have a clue as to what i was asking for. They finally had to call owens corning directly. i need 10 sheets for one wall in my basement. owens corning will only ship a quantity of 128 sheets or more. What good is it having a user friendly product if you cannot buy it.

Why has the dimension of the grove/shiplap on the foam board changed and how can it be strapped?

I've checked both Home Depot and lowes and found the same thing. That is, the depth of the grove / shiplap on the 1.5 inch foam board is greater than 3/4 inches in depth. This precludes the use of 1x3 strapping since the result is that the foam board now protrudes beyond the strapping and that make it difficult to apply the wall board. The salesman at Home Depot suggested using 5/4 lumber to fill the gap between the sheets of foam board. That works, although leaving about 1/4 inch of the wood above the surface of the foam board, but it's way more expensive than using strapping. What's going on?
Asked by: Paul
I noticed that as well. Actually, what I've noticed is that each foam board is different. No 2 seem to be alike except for that, as you point out, none of them work with a piece of 1x3. If your covering it with plywood (like in a basement workshop) you will be fine, but if your installing drywall over it, you may need to do some creative and extensive shimming. My local lumber yard sells something they cal "Super Boards" All it is, is a piece of 1x that is only dressed on 3 sides, with one side still rough. This results in a board that measures 7/8". That extra 1/8" might be just enough. The down side is they only come in 1x6 or wider, so you will have to rip them.

Basement walls with a beveled bottom portion of the wall

In my basement, the bottom four inches or so are sloped inward, probably due to some masonry designed to prevent water entry at the wall seam. In addition, there is additional masonry (1/4 inch or less) on the bottom four feet of the wall, probably for the same reason. the result is a wall that is not flush from top to bottom. Would this product be able to be attached directly to the basement wall or would you suggest framing the walls and using another product as a moisture barrier/insulator? If so, what product would you suggest? Thank You!
Asked by: Scott
Dear Scott: Yep, sloped walls create a number of problems. A couple of suggestions: (1) Poly moisture barrier: Start with a thick poly moisture barrier, laid against the concrete wall and carefully sealed at the top, sides and seams with DAP 230 -- to block air and moisture leaks. (2) Foam board: Mount 1" foam board on the concrete wall, down to the level where the wall begins to slope inward. Seal all of the edges and joints carefully with DAP 230. Then add a second 1" layer of Foamular, which will probably reach down to the floor. If a gap remains, fill it with the 'Windows and Doors' version of Great Stuff, which remains flexible. (3) Build your 2x wood wall in front of the foam board, so that the studs do not touch the concrete. To boost insulation, fill the stud bays with Roxul rock wool, which provides R 4.2 per inch. (4) Also cover your floor with a poly vapor barrier and at least 1" of foam board -- and seal all of the joints and edges carefully with DAP 230 and Great Stuff. Lay 3/4" plywood on top as the nailing / glue surface for your flooring, with the panels perpendicular to the foam board seams. Seal the plywood carefully with DAP 230. (5) If there is any hint of a water problem in your basement however, start with DriCore panels -- and make sure there is a drain / sump pump to remove water leakage. Then install the foam board and plywood, if you have sufficient head room. (6) (4) Also read up on fire blocking, which is required at the top of basement walls, stairs, etc. Do a Google search for "How to firestop your basement" from Contractor Kurt. Roxul rock wool is a good solution (also available at Home Depot). You can stuff it into the gap at the top of the wall and into the end of floor joist bays. Rock wool is much denser than fiberglass, molds kind of like clay, and stays where you put it. I hope this is helpful, Mark
