Frame Backings

Farme Backing
When choosing a FRAME BACKING you can choose either a pH-neutral buffered  board (long term storage) or an acid & lignin-free buffered board (indefinite storage).

We stock three different materials for frame backings:
•  Long-term Display - Matboard - White, pH-neutral, buffered, 1/16" thick.
•  Indefinite Display - Conservation Board - White, acid & lignin-free, buffered board (.040" thick) for 8 x 10" thru 12 x 18" frames.  Foam Board - White, acid-free, buffered, 1/8" thick for 16 x 20" thru 24 x 36" frames. Both are Approved by the Library of Congress for indefinite display (hundreds and hundreds of years).
