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.
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.
Fire Glazing Systems
We use a variety of fire certified glazing systems to meet the required specification and fire door ratings.
Listed below are the most common ones used based on the typical performance criteria required. These are all independently tested and accredited under the BWF-CERTIFIRE scheme.
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.
Vision Panel Designs
Glazing designs improve safety in busy environments because of the ability to see through them as well as offering improved design attributes. The panel design choice will depend on the performance requirements of the door set.
Our technical team will assist you to explain the options and ensure the correct glazing is specified.
We can offer clear, obscure and manifestation designs of glass for fire and non-fire glazed doors.
Why not add some full glazed side screens with your doors to lighten up a dark hallway?
We can offer a wide range of 30-minute and 60-minute fire rated screens and walls to complement your door designs or create airy work spaces. We can also offer a range of acoustic screens and walls to achieve 29dB and 50dB.
Our vision panels are manufactured from high performance hardwood timber suitable for any residential or commercial application. All glazing is fully tested and certified to meet fire regulations.
