High-Stress Monolithic Fire-Rated Glass

This fire-resistant glass is manufactured by applying a special fire-retardant solution onto the surface of float glass, followed by tempering. Tempering enhances the glass surface’s resistance to thermal shock and mechanical strength, while the fire-retardant coating reflects heat during a fire and forms a protective layer on the surface, delaying glass breakage at high temperatures.

Product Structure

Monolithic Structure: Thickness ranges from 5 to 19 mm.

Key Features

  • High Strength: Tempered to develop high surface stress, the glass can withstand greater mechanical impact and temperature fluctuations.
  • Fire Performance: Coated with a special fire-retardant layer, it resists penetration by flames and smoke during a fire, delaying fire spread (Class E fire rating) with a fire resistance duration of 0.5–1.5 hours.
  • Lightweight and Transparent: Compared with multi-layer insulating fire glass, it is lighter, thinner, and offers high visible light transmittance and excellent visual clarity.
  • Cost-Effective: The manufacturing process is relatively simple, making it less expensive than laminated insulating fire glass or high-borosilicate monolithic fire glass.

Applications
