3/16" acid free white foam board, sold in 32"x40" sheets. The professional framer’s choice for a mounting board that’s totally acid-free. Features facing paper with a pH between 7.7 and 8.5. Made with a calcium carbonate buffer that provides many years of protection against pollutants that cause paper to become brittle or yellow with age.

Foamboard is an excellent lightweight product for framing, mounting, or simply backing in a poly bag. Foamboard has a solid core and is very rigid, making it useful for a wide variety of projects.

Features double clay-coat paper surfaces with an ultra-smooth finish and tough-yet-pliable polystyrene memory core that “bounces back” after handling, cutting or mounting.
