Foamboard & Backing Board
Foamboard & Backing Board are the support layers that sit behind your artwork inside a frame. Foamboard provides a smooth, rigid surface to mount or stabilize your piece, preventing warping or buckling. Backing board is the final protective layer, sealing the frame from behind to guard against dust, moisture, and handling. Together, they keep your artwork flat, secure, and well-protected over time.
