2 Hour Fire Rated Building Glass / Fireproof Glass

Borosilicate fire rated glass not only has superb fire resisting performance but is extremely hard for glass. With low expansion coefficient, high softening temperature, light weight, high mechanical strength, and good fire resistance. It is the preferred material for monolithic fire protection. It can also be made into building energy-saving fireproof materials with better overall effect by coating, hollow, sandwich and other methods.

The advantage of Borosilicate fire rated glass:

1.  Excellent fire resistance

The ultra-high softening point provides a fundamental guarantee for the fire resistance stably, and the fire resistance time exceeds 120 minutes. With ultra-high transparency, colleagues who maintain the transparency and beauty of the building can still ensure people’s vision for escape and rescue in the event of a fire.

2. Super high chemical stability

Acid resistance       Level H2 (1.1 mg/dm2 6h)

Alkali resistance      Level A2 (86 mg/dm2 3h), 

Good fire resistance, stable and not afraid of ultraviolet rays;

3. High-strength and ultra-light performance

The glass is more than 8% lighter than ordinary glass, and at the same time has ultra-high mechanical strength, extremely strong and light characteristics, significantly reducing the weight of the building;

4. Excellent optical performance

Low iron, environmentally friendly formula, high light transmittance, visible light transmittance 92%, excellent optical quality provides distortion-free visual effects
