The dust cover, also known as the backing of the frame, is the finishing touch for conservation framing. This material, as its name suggests, protects the inner frame from any dust particles. Additionally, our selection of backing types includes both PVC foam boards as well as plywood.
The benefits of selecting a PVC foam backing board varies from frame to frame. One key benefit is that PVC foam board is an anti-absorbent layer that prevents moisture from seeping into the inner frame.
PVC foam board is also a much lighter material, reducing the overall weight of the frame, and increasing the ease with which it may be stored or transported.
