Diffuser Board
Diffuser Board is a 4 pcf density board made from strong, resilient glass fibers bonded with a thermosetting resin. The airstream surface of the Diffuser Board features a black coated surface that minimizes visibility of the board at the diffuser and register boxes. Diffuser Board is available plain or with an FSK (foil-scrim-kraft) facing laminated to the exterior surface of the board.
