2021-11-01       Source:

With the continuous improvement of building energy saving requirements and frequent fire in recent years, all industries have higher requirements for smoke control and exhaust duct in buildings. It is not only required that the smoke control and exhaust duct has thermal insulation function, but also needs to have the ability of fire prevention. Fire insulation glass wool is widely used in smoke prevention and exhaust duct, for fire insulation function has played a great role.




Fire insulation glass wool has safety performance, belongs to non-combustible material, generally need to be tested by the national testing department fire performance for non-combustible A1 class.




High quality fireproof thermal insulation glass wool has good thermal insulation effect, as well as uniform slender fiber, and certain sound absorption and noise reduction performance, hydrophobic performance, can isolate water vapor, to ensure the stable thermal insulation performance of glass wool. The raw materials of glass wool, together with the formula and production process, have excellent durability, while non-corrosive, and will not produce metal corrosion and stress corrosion on the duct.




Domestic several thermal insulation glass wool production manufacturers have passed the national fireproof construction material quality supervision inspection center "detection, and satisfy the ventilation pipe refractory test experiment method (GB/T17428-2009 test, fireproof limit of 1.0 H, 1.5 hours, as long as strictly according to the report of test pieces of the structure and operation process can be smoothly through the acceptance.
