INSUL GLASS HT FIB AL SI 25 800 C: Tri-layered fire-resistant heat insulation - 800 C


INSUL GLASS HT FIBAL SI 800INSUL GLASS HT FIB AL SI 25 800 C is a tri-layered fire-resistant heat and sound insulation made of unwoven glass fibers and silica fabric on the hot side and aluminized linen made of glass fibers on the outer side, with a cumulative thickness of 25mm.

The inner layer is made of silica fabric constantly resistant to 1000°C and wool made of fire-resistant glass fibers that effectively isolate heat up to a temperature of 800°C.

The outer layer made of glass fibers is resistant to a constant temperature of 550°C, aluminized, which excellently reflect heat radiation.

The insulation is densely sewn over with an annealed aramid thread.
