90 minutes fire rated glass (integrity only) doors/windows/partitions(E90)
The "Integrity" (E) rating signifies that this glass maintains its structural integrity under extreme heat, crucially preventing:
- ✓ Flame Penetration: Absolutely no passage of flames to the unexposed side, maintaining a critical fire barrier.
- ✓ Smoke and Gas Migration: An impenetrable shield against lethal smoke and toxic hot gases, which are the primary threats to life in a fire.
The 90-minute fire resistance glass far exceeds standard requirements, offering invaluable time for complex evacuations, specialized firefighting efforts, and the protection of high-value assets.
For the most demanding fire protection scenarios, 90-minute integrity fire-rated glass (E90) stands as the ultimate transparent barrier. This advanced glazing is engineered to deliver an unparalleled level of safety, providing a robust, certified defense for a full hour and a half during a fire event. When building codes require extended fire containment, or when protecting highly sensitive areas, E90 fire glass is the solution you need.
