  • 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.

  • 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.

Can I glue this product to an dry interior block crawlspace wall? What adhesive would work best?

Asked by Gary October 21, 2020
1
Answer

Hello Gary, Foamular can be attached to a block wall using an adhesive. Owens Corning does not test specific adhesives, adhesives that note compatibility with foam or foamed polystyrene can be used with Foamular. Foamular is a combustible product and in most applications needs to be covered by a 15-minute thermal barrier such as 1/2" drywall. Foamular can be installed without thermal barrier in a crawlspace, providing the conditions specified in the Underwriters Laboratories UL ER8811 are met. Please see link below to the UL Report. https://dcpd6wotaa0mb.cloudfront.net/mdms/dms/EIS/10019986/CC_UL_Code_Report.pdf?v=1591017360000. Thank you for your inquiry!

The material has consistent density and cuts fairly easily with a long blade. Definitely a quality material that bonds well with urethane expanding foam. Our build was a bit non-traditional for this material in that we used it to construct a 16.5 cuFT cooler. How do you transport 300 lbs of freezer beef four hours in the summer? Foamular 150!!

This stiff insulation sheathing is perfect for what I want. While replacing the siding on my house, I discover there is no insulation between the floors. So where my second floor overhangs the first floor, the siding sheets I remove have provided the only insulation. I am able to cut the FOAMULAR sheets and fit them under the subfloor and between the joists. Though time consuming, I believe this product is my best choice for my modification.
