Matboard sheets, or mountboard sheets, are the paper board sheets from which window mats, or window mounts, are cut by picture framers, artists and hobbyists. Window mats, or window mounts, are more often simply called ‘mats’ and are those coloured 'cards ', 'borders' , ‘surrounds’ or 'edges', which separate, and go on on top of the picture, when it is framed. These boards are of full-size, 32"x40" inches (81.6 x101.8 mm), Acid-Free, Bright White Core, Akaline Reserve 3%-5%, Fade Resistant and of the Standard 1.4mm 4-ply thickness.
