  • FOAMULAR 150 and 250 are available in various thicknesses and R-values, the difference is the compressive strength. FOAMULAR 150 has a compressive strength of 15 psi and FOAMULAR 250 is 25 psi
  • FOAMULAR is not rated for STC (sound transmission) and does not have any soundproofing properties. Owens Corning fiberglass batts and rolls are great options for acoustic applications.
  • When using FOAMULAR or any low perm insulation, always verify the moisture vapor flow and dew point characteristics of the wall system. Please check your local building codes for vapor retarder/barrier information.
  • If being used in an interior construction application, painting the FOAMULAR is not recommended as FOAMULAR cannot be left exposed and will need to be covered by a 15 minute thermal barrier such as drywall.
  • If being used for crafts, acrylic or latex based paints can be used with FOAMULAR products.
  • If you're looking to insulate your garage door, Owens Corning Garage Door Insulation Kit is an easy, fast and affordable way to keep your garage warm in winter and cool in the summer.
  • If you're looking to ventilate your attic rafters, Owens Corning Raft-R-Mate is a XPS foam vent designed to assure unrestricted airflow from the soffit to the ridge vent.
  • FOAMULAR is available in two edge configurations:
  • Square Edge - designed to fit flush next to adjoining boards
  • Scored Square Edge - comes with 3 factory scores, so that you can take a 4' sheet, break it in two and have two, 2' wide sheets (middle score), or you can break it into three 16" wide pieces by snapping at the left and right score.

Q:Can these panels be installed horizontally under a subfloor in between the floor joists to insulate the floor?
by|Feb 9, 2024
1 Answer
Answer This Question

A:  Hello James, While Foamular can be cut to fit between joist, the insulation is not sized for this application. It is labor intensive and typically produces quite a bit of waste. Thank you for your inquiry!

    A:  Hello fran, we do not have recommendation for this using this product in this type of application. If used, it must be protected from UV rays as it will degrade the product over time. Thank you for your inquiry!

      Q:Can I use 1 inch Foamular on new construction exterior over my Tyvek and nail my window flange directly to the foam with longer nails to reach my OSB and studs? Or do I have to buck my windows out with 1"x4"s ? Will 1 inch help thermal bridging in zone 5

      Answer This Question

      A:  Hello Kevin, We would recommend checking with the window manufacture for their recommendations. While 1" will help and provide continuous insulation, we would suggest checking with your local code officials for R-value requirements in your area. Thank you for your inquiry!

        Q:Is this insulation able to be used in a welding shop without being covered by something else? I was thinking about putting it on the inside of my sliding steel doors.

        Answer This Question

        A:  Hello Dale, Owens Corning Foamular products are combustible and must be covered by a 15-minute thermal barrier such as 1/2" drywall. Owens Corning does not have recommendations for the specific use you have described. Thank you for your inquiry!

          Warning - they raised prices by around 40%
          I bought a bunch of these in November and December 2023. Fast forward a couple months to February 2024 and the price had gone up by around 40%!! All those good reviews no longer count since the value went down by 40%. I'd suggest looking for other options based on the new pricing.

            Great product, fills my needs. I do recommend to use a fine tooth circular saw to cut the 1 1/2" boards, makes a smooth quick cut.

            Insulated my 30x40 pole barn garage with this. None of the snap off sizes fit what I needed but it was easy to cut. I can tell a big difference in the temperature inside.

            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.
