Our archival matting options for artwork range from window mat, to island window mat, to float (backmat only). Visually, the window mat provides a field around the work of art, isolating it from both the frame and its surroundings. The major protective function of a window mat is to separate the work of art from the glazing surface; and to help support the perimeter of the paper sheet.
Commercially available mats are made as thin as 2-ply, about 1/32″ thick, and up to 8-ply which is 1/8” thick. At Bark, we custom mount thicker mats – always from 100% cotton rag board -- up to about 3/8” thick. Our art preservation technicians have a keen eye for detail, filing the bevels and extracting any imperfections by hand. The result is a truly flawless opening for your artwork.
