Fire Glass Door

The presence of fire-rated doors with glass is often overlooked. Even if it seems to be nothing more than an ordinary and clear pane of glass, its existence may suddenly become a matter of life and death if a fire breaks out. When it comes to fire safety in buildings, this specialised construction material plays a critical role because of its high resistance to flames, heat, and smoke.

How fire rated glass doors made?

Toughened glass is sandwiched between intumescent interlayers to create fireproof glass doors. When placed near a flame, the glass will swiftly heat up and shatter into many fragments. Shattering triggers the intumescent interlayer, which expands and efficiently repels flames, heat, and smoke, preventing further damage. Fire-rated aluminium doors are added to the construction, which keeps the broken parts in place during a fire and increases the overall safety and security.

Using a fire-rated glazed door as a fire barrier helps keep the flames contained and prevents them from rapidly spreading throughout the house. It lessens the amount of devastation and gives people time to escape safely. Fire-rated internal glass doors undergo rigorous testing when it is created. The results of these tests are used to provide an official fire protection grade to the glass, assuring its viability for usage in emergency scenarios.

What type of glass is used in fire doors?

According to building codes, all rated fire doors that incorporate glass must utilise fire-rated glass. This is a form of glass that has been exceptionally engineered to guard against the spread of fire. Flames and smoke can’t get through the glazed fire-rated doors. Therefore, the glass acts as a barrier to impede their spread. Frameless glass fire doors also serve as an insulator that shields other parts of the building from the heat of a fire.

Standard glass can endure temperatures of 120 degrees Celsius for just a few minutes in a fire. Fire-rated glass door residentials can resist temperatures of up to 900 degrees, which is seven times higher than conventional glass. For nearly 60 minutes, double fire doors with glass can withstand these temperatures and keep the fire from spreading, giving everyone time to get out safely and for firefighters to arrive.
