Questions & Answers

Q:I need to insulate my garage door. Can the 2" Foamular be used for this purpose?
by|May 12, 2024
1 Answer
Answer This Question

A:  Hello David, Hello Arch, Owens Corning Foamular products are combustible and must be covered by a 15-minute thermal barrier such as 1/2" drywall. We do not recommend using Foamular to insulate a garage door. There are better choices such as the Owens Corning Garage Door Insulation Kit. Thank you for your inquiry!

          Rigid, strong, lightweight, sticks well with spray foam, I used it on interior basement wall replacing sheet rock. This doesn’t mildew. Applied stocko over it.

          Product was fine. Delivery arrangements were good. Product wasn't protected from the tightened truck straps causing a return of 9 sheets $$$ which somewhat defeated paying for a delivery.
