Fire Resistant Glazing

Glazing has a major impact on fire performance – the aperture shape and position, and style of bead and glass – are all major influencers.

 

Therefore, when forming a glazed aperture in a fire resistant door or wall it’s essential that correct fire resistant glass is installed.

Fire Resistant Glazing

Choosing the Right Glass

There are three main fire related threats to consider when choosing glass for an application.

 

Smoke is one of the main causes of fire deaths and obscures visibility which impacts on seeing escape routes if a fire breaks out.

 

Flames will cause the fire to spread which will destroy property and potentially cause fatal injuries.

 

Radiated Heat causes the spread of fire through combustible materials.

Insulation and Integrity

There are various glazing options which, when combined with the appropriate glazing system, will provide a solution to combat smoke, flames and radiated heat. These are classified as E, EW and EI.

Fire Glazing Components

The glazing cassette comprises of the fire resistant glass, a fire glazing system and the glazing bead.

 

The fire resistant glazing system holds the glass firmly in place during normal use, but in the event of fire the intumescent material expands, securing and insulating the glass and protecting the surrounding timber.

Glazing Beads

Glazing beads are required on both sides of the glass and will be aesthetically finished to match the door. We can provide a variety of bolection beads or a flush bead depending on design requirements. The flush bead provides cleaner sight lines whilst a bolection bead offers a more traditional look suitable for all applications apart from sliding doors.
