What is Fire Resistant Glass?

Fire resistant glass (sometimes just called “Fire Glass”) is a type of specially-treated glass designed to resist the effects of a fire for much longer than ordinary glass could, acting as a barrier to the fire and preventing it from spreading for a time.

Fire rated glass is a vital component of many fire safety programmes, buying valuable time for evacuation to occur and countermeasures to be deployed. Able to resist direct exposure to flames for up to an hour, properly-installed fire glass can also work as an insulator – stopping not just the flames and smoke of the fire, but the heat as well.

Where fire control is concerned, containment and time are extremely important factors. An uncontrolled fire will spread rapidly, and may pose a serious danger to your staff, your premises and your building – help to ensure it never gets out of control with high-quality fire glass from The Glass Warehouse.

Fire Resistant Glass

Fire resistant glass is treated to make it much more resistant to heat than normal (with some fire resistant glass from The Glass Warehouse able to resist direct exposure to flames for up to an hour). In addition, many types of fire rated glass are able to stop the transfer of heat through the glass for a certain time period, containing not only the fire, but its heat as well.

Fire glass brings with it a set of safety advantages that ordinary glass simply can’t offer – even tempered glass yields much more quickly to flames, letting them spread through the area uninhibited.

The Safety Advantages of Fire Resistant Glass

Fire resistant glass is able to contain the spread of fire for a time, with a much higher melting point than ordinary glass and the ability to resist high heat for a set length of time. By comparison, ordinary “annealed” glass and even tempered safety glass are destroyed very quickly by fires, often falling from their frames or melting entirely almost immediately when exposed to flames.

How Fire Rated Glass is Made

Fire resistant glass is made in a number of ways, depending on the fire rated glass you choose. Georgian wire glass, for example, has an internal wire frame (often visible as a crosshatched steel wire pattern in the glass), which is inlaid while the glass is being made. This wire acts to hold the glass together at high temperatures, preventing it from sagging out of its frame and collapsing.

Another prominent fire glass type is made quite differently, by the Pyroguard and Pyrobel brands. These fire glass types are made with a heat-resistant, fire-resistant resin which is protected by two or more layers of glass, creating a transparent pane of glass which is able to resist the attacks of fire and high heat for up to an hour.

Many other types of fire glass are available from the Glass Warehouse, with many made in their own ways to achieve their impressive results.

The Capabilities of Fire Glass from The Glass Warehouse

The fire glass available from the Glass Warehouse is part of a range, with variety of capabilities to help protect your business and staff from fire. The ratings available for fire resistant glass are explained below.

The Ratings Available for Fire Rated Glass

When you are browsing fire glass from The Glass Warehouse, you will see a range of ratings for the glass – for example, “60/30” or “60/60”. Fire rated glass is rated this way to show the length of time in minutes which fire rated glass is able to resist before melting as the first number, then the length of time (in minutes) which the glass is able to insulate heat from the fire for as the second number.

Therefore 60/30 indicates that, when exposed to flames, that piece of fire-rated glass will be able to remain solid in its frame for 60 minutes, and can contain the heat from the fire for 30. After 30 minutes, heat from the fire will have completely conducted through the glass, but it will still remain solid for the remainder of its 60 minute lifespan.

Using Fire Glass as Part of a Fire Safety Programme

Fire glass should never be the entirety of your fire safety programme. Fire resistant glass is able to delay and limit the spread of fire around your premises, but it can’t stop the fire on its own – that’s the job of a fire suppression system such as a sprinkler system, or the local fire department.

However, the resistance to a fire’s spread offered by fire resistant glass often contains the fire to a small enough area that suppressing it completely becomes a much simpler matter. The containing effect of the fire resistant glass creates time for emergency services to respond or your own suppression methods to kick in, too, stopping the blaze from spiralling out of control.
