Air-conditioning duct insulation are in the form of flexible rolls, semi rigid and rigid slabs manufactured from stable glass fibers bonded with thermosetting resins, and free from coarse fibers and shot, easy to handle and cut to fit rectangular ducts and air handling equipment.
For facing, there are two options; one is non faced and the other with glass reinforced Aluminum foil/kraft laminate facing (FSK) which combines a pleasant appearance and excellent vapor resistant. The most common used roll thickness to be 40mm and nominal density 48 kg/m3 or 3 lbs/ft3. Boards are 64kg to 96kg.
