Superglass Contract Mat 44 is designed to be used as thermal insulation between and over the timber joists of new and existing lofts/cold pitched roofs.

Superglass Contract Mat 44 is a lightweight, non-combustible glass mineral wool insulation roll. The flexible roll is cut at 2 x 570 mm widths to allow friction fitting between and over common joist spacings, reducing the need for on-site cutting and waste.
