FIRE DOOR PROTECTION from Astroflame

FIRE DOOR PROTECTION

Astroflame supply a range of products to complete or enhance the protection provided by standard fire doors.

While the door itself is designed to slow down the progress of a fire the frame and fittings must also be upgraded to provide the proper level of protection. Where vents of windows have been introduced into the door these features must be upgraded. This applies to door furniture too.

The objective off passive fire protection is the containment of fire and toxic gases by inhibiting flame penetration, heat transfer and transport of toxic gases from the site of a fire to other parts of a structure.

FIRE & SMOKE SEALS:

Even where the door is supplied complete with appropriately protected vents or windows the gaps around the door must be sealed to prevnet the spread of fire, smoke or gases.

For sealing the perimeter of fire doors we supply fire seals based on intumescent materials that undergo a chemical change when exposed to heat or flames. These become viscous then form expanding bubbles that harden into a dense, heat insulating multi-cellular char. The pressure exerted by the expanding seal must be sufficient to seal off flames and gases but not so great that fire and rescue services have great difficulty in opening doors while carrying out their jobs.

To provide fire and smoke protection together with acoustic and thermal sealing we have developed QuadSeal which has been certified to fulfill all relevant requirements of Approved Documents B, E and M in a single seal.

CERTIFIRE APPROVAL:

All seals are tested by an independent laboratory to ensure that they meet the required BS or EN standards.

Our products also have UK approvals for -
British Building Regulations Approved Document B.
Lantac Building Control Approval
NHBC Type Approval.

FIRE DOOR PENETRATIONS:

Letterboxes, grilles & vents, glazing and door furniture compromise the function of a fire door unless these fittings also have passive fire ptotection properties. We supply products to maintain fire door integrity and also an approved safe fire door retainer that releases automatically when fitted as part of a fire alarm system.

DOOR DECORATION:

Burning paint can flake off and spead fire and we sell a range of paints and coatings for treating timber to prevent or reduce this risk arising. The range includes a clear fire varnish as well as a range of decorative flame retardant paints in gloss, eggshell, matt and vinyl finishes.
