The Definitions of Fire Glass

When normal untreated glass makes contact with raised temperatures and the intense pressure caused by a fire it will more frequently than not buckle under the acute pressure and will crack or shatter totally and in some cases explode.

If this glass were to be part of a door it may be catastrophic for the inhabitants of a building as the shattering glass could cause injury to person and property. There is also the added danger that any crack in the cup of a door could cause the door, which would be otherwise providing an insulating barrier against flames or smoke, to lose its integrity and let dangerous fire thru where it might cause harm or just allow smoke to go through the frame and cause damage to person and property.

Specifically Treated Glass

For reasons of personal and property safety, as well as the legislation which governs public safety and building and business owners as part of H&S regulation as well as the Regulatory Reform (Fire Safety) Order 2006, it is essential that any doors can withstand fire.

It is obvious therefore that any glass which is employed in doors, particularly those which are labelled and classed as fire doors with glass, have received special treatment and may be able to bear the effects of a fire, however harsh it could be.

When it is considered that untreated glass can withstand temperatures of up to 200c while tempered glass can withstand 500f and fireproof glass can put up with temperatures up to 1600f it is no wonder that home and business owners favor safety as well as adhering to their legal needs when it comes to buying fire doors with glass.

How is Glass Treated?

There are a bunch of ways in which glass can be handled to give it the capabilities which would be needed to allow it to stand up to the intense temperature and pressure which can often be created by a fire. Given the temperature of a fire can rise dramatically within a particularly short period it's important that fire doors with glass may be able to work right away and can be sure to function in even the most extreme fire scenarios.

The diverse coatings which are part of the producing process are being constantly developed and evaluated by experienced and qualified fire engineers in laboratory conditions which mirror real life fire conditions to ensure that at every point the door and accordingly the glass contained within fire doors with glass are able to guarantee at least a 30 minute integrity and insulation period of time in the face of fire which would mark them out as an FD30 certified door.
