Description:

Rigid foam insulation for exterior walls contains hundreds of millions of densely packed air cells to provide exceptional thermal performance. It’s also virtually impervious to moisture, preventing loss of R-value due to moisture penetration. FOAMULAR® weighs considerably less than plywood, OSB or other non-insulation material so it's easier, faster and safer to install. Plus, the product's built-in rigidity means it can be scored and snapped, cut, or sawed with common tools. Sagging and settling are never a problem.
