Intumescent Glazing

Glazing in fire doors and screens is an important safety measure. It lets people see hazards ahead, including fire and smoke.

But adding glazing to a door creates a point of weakness. Where the timber and glass meet, fire can take hold. Also, without support, the glass can quickly slump and fail in the extreme heat of a fire.

Our intumescent glazing systems hold the glass firmly in place. In everyday use, this stops the glass from rattling. In a fire, the glazing channel or strip expands, preventing the glass from slumping. It also stops heat transferring to the timber, so fire cannot take hold around the edges of the glazing aperture.

Our systems include a glazing channel or strip, beading, and in some cases an intumescent liner. Glazing can be only installed in a fire door if the test evidence permits; and systems should always be installed exactly as stated.

Fire resisting glazing is more than just glass.  The selection and fitting of an appropriate fire seal to glazing in fire resisting doors and screens is vital to the performance of the system.  Our comprehensive range includes:
