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 & 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

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.

GLAZING SCREENS

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.

Secured by Design is the official UK Police flagship initiative supporting the principles of ‘designing out crime’.

Secured by Design focuses on crime prevention of homes and commercial premises and promotes the use of security standards for a wide range of applications and products.

The principles have been proven to achieve a reduction of crime risk by up to 75%, by combining minimum standards of physical security and welltested principles of natural surveillance and defensible space.

The objective is to reduce burglary and crime in the UK by designing out crime through physical security and processes.

We offer a range of Secured by Design multifunction front entrance door systems which hold Dual Certification for both enhanced Security PAS24:2016 and resistance to fire to BS EN 1634-1 and part ‘M’ of the building regulations.

We offer a wide range of PAS24 high security doorsets which are designed to offer a higher level of security for dwellings and other buildings exposed to comparable risk. They meet the enhanced security performance requirements for doorsets and windows in the UK.

PAS 24: 2012 provides a method for testing and assessing the enhanced security performance requirements of external doorsets and windows providing an easier specification requirement for developments. PAS24 covers doorsets and windows of all material types.

Products are still obligated to meet the material specific requirements as detailed by the product standards for doorsets and windows.

The entire manufacturing process is carefully controlled and monitored. From the selection of raw materials, through to design, precision machining, manufacture and technical support on every aspect of door provision for both domestic and commercial properties.

Our doorset offer is diverse and consists of:
