It is important that the integrity of a fire door is not compromised by incorrect installation or the addition of a new feature, such as a door viewer. To that end Astroflame supplies products to maintain fire door integrity.

Intumescent fire seals and intumescent smoke seals, independently certified to the appropriate BS:EN standards ensure that the 30 or 60 minute fire rating of a fire door is maintained. Naturally the fire seal / smoke seal should blend in with the decor of the door/frame so Astroflame manufactures fire door seals in a range of colour finishes, including wood-grains. Similarly smoke seals are available in a range of carrier colours and brush piles.

A typical example of introducing a weak point in a fire door is the installation of a letterbox or a security viewer - unless fire rated components are used. Astroflame supply three models of intumescent letter-box (fire, fire & smoke and fire,smoke & acoustic) and two fire rated door viewers to maintain fire door integrity.

Similar issues arise if down lights are introduced into a fire rated ceiling - the potential for the spread of fire and fumes must be mitigated by fitting lighting fire hoods.

In fact wherever you make a hole through a fire rated structure Astroflame can supply a correctly certified passive fire protection product to restore fire integrity - give us a call.
