Fireproof glass wool sandwich,made of pure glass stone,using high speed radial separation process,to produce 5-8um diameter thin and uniform glass cotton fiber,internal to the pure inorganic matter,not because of time and reduce the heat insulation effect,the overall structure of matter uniform density.

 

Glass cotton advantages:

Has the incombustibility,fire resistance grade.

Is not easy to absorb water,aging resistance.

Thermal insulation performance.

Acoustic noise.

Biodegradable,environmental protection.

Acidity coefficient is low,greatly reducing the corrosion of metals.
