Product Description

The flexible duct fire roll material is a fire-protection material specially designed for ventilation or smoke exhaust ducts in building engineering. It is mainly composed of aluminosilicate (silicate) fiber blanket and a high-temperature insulation material made of calcium oxide, magnesium oxide and silicon dioxide, which can provide good insulation performance below 1260°C for a long time.

Flexible fire roll materials are mainly composed of inorganic non-combustible substances. Even if a fire occurs, it will not disperse harmful gases due to changes in ambient temperature. It has good fire resistance performance, can control the fire in the initial unit, effectively isolate toxic gases, and allow people enough time to evacuate and rescue, avoiding major casualties and property losses.

Product Features
