  • 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:What do the different R values mean? If using this product to insulate a 20’ container which would be best? Thank you

1 Answer
Answer This Question

A:  Hello KimC, the R-value is the thermal resistance of the insulation. The higher the R-value the greater the insulating value. Thank you for your inquiry!

      Answer This Question

      A:  Hello gerard, if the product is being used for crafts it can be painted with a latex paint. If being used as a building material, the product is combustible and must be covered by a 15 minute thermal barrier such as 1/2" drywall. Thank you for your inquiry!

        A:  Hello, All Foamular is combustible and requires a protective barrier or thermal barrier. To comply with building codes, all foam plastics must be covered with a 15-minute thermal barrier. Gypsum board minimum ½” thick is a common covering. Thank you for your inquiry!

          I used the sheet to make my elder border collie an in-garage warming station. She’s too old to get into a dog house any more, so I created a walk-in insulation shelter for the garage. With a small ceramic heater, the warming shelter works great. Unfortunately, my dog doesn’t want to use it. Oh well, good product, just a bit pricey.

          Easy to cut and install
          I had to use washers and screws to keep these up. It worked great to keep my insulation in my attic up between the walls for my vaulted ceilings

            Garage door insulation
            Easy to work with, doesn’t leave a HUGE mess of little styrofoam balls. Easy to cut with razor knife and framing square. Used on west facing NE FL garage doors (single & double) Lowered the inside temp of the doors from ~130 to 100. Will certainly help keep ambient temperature of garage down too.

              Great for installing Window AC Units
              Our AC went down and we need to upgrade from a 4 ton to a 5 ton system w/ additional duct work/electric costing $7000min here in Central Florida. Bought x5 Window units, and installed with this R-5 Foam Insulating Board. Got the idea at first off Reddit, which brought me here. The smaller 1"x2'x2' panels weren't in stock, so had to get the 8' board instead. Very easy to cut down with a box cutter knife. Sealed up with some window/door flashing tape (which was recommended by the sales associate). As we are in a area that gets lots of bugs and rain, wanted to be sure everything was tight.

                I had to use this product on an attic re-insultation project that required a new engineered approach to the solution. The product was a success in its application. It is super easy to use and cut or trim in place, especially for tight quarters. The house was a 1930s cape cod with shallow 2x4 ceiling joists. The detail required building up the 2x4 ceiling joists to provide a cavity depth that accepts 2 layers of R-19 or one layer of R-38, then cap the enitre area of rolled insultation with R-10 rigid foam to provide a minimum R-rating of 48. Additionally, capping the entire area with rigid foam enabled a platform working surface for future attic accessibility and wiring/ventilation/interior roof maintenance. Overall, very impressed with the product.

                Product does what I needed to. Used as full sheet to insulate along my basement walls and then frame next to it. This helped reduced install time so I wasn’t cutting them to fit perfectly in between studs. You can feel the difference in temperature and the price was better on my wallet too

                Did not work as advertised
                I put up Foamular sheets under polycarbonate roofing panels in my gazebo. Figured since the sheets were advertised at able to withstand temperatures of 165 Deg F, they would be fine. Not so. The sheets just buckled and warped and stuck to the polycarbonate. They also shrank in thickness from 1in down to less than 1/2in. The sheets became very brittle and just cracked. The temperature was over 100 Deg F, maybe 110 Deg F, but nowhere near 165 Deg F. Looks like they do not handle being exposed to sunlight - even if under polycarbonate sheets. Have to peel them off - they are stuck to the polycarbonate - in pieces. Also the polycarbonate sheets are ruined. Have to figure out how to maybe sand down the stuck on bits of Foamular.
