3/16" Acid-Free Foam Core

3/16" Bainbridge Acid Free Foam Core Boards

Bainbridge 3/16" Acid-Free Foam Core is the finest available. Unlike other foam core boards sold elsewhere, ours are 100% cotton and acid-free, never yellowing, becoming britte or harming your work. Foamboard makes a perfect addition to our archival mats, protecting your valuable work for generations to come.

The 3/16" thickness is sturdier and has more depth that our 1/8" size., making it just the thing for freestanding displays, frame fillers and mounting. Super lightweight, yet very sturdy, Foam Core makes a great mounting surface, offering the right balance of rigidity and lightness. When framing your pieces, use our archival Foam Core, instead of acidic cardboard as a backing or filler. No acid will be introduced into your frames and your artwork will truly be protected.
