INTRODUCTION

When fire strikes, gaps around doors are a perfect escape route for the fire to travel, therefore it is crucial to halt the spread of flame and smoke by fitting Intumescent Door Seals. Intumescent surface-mounted seals offer an easy and speedy solution to this problem. Below are some of the key benefits offered by these seals:

  • No rebating or drilling needed
  • Labour cost-saving
  • Only requires a 3½mm gap at head and closing edge and 1mm at hinge edge of door
  • Available in a range of colours and wood veneer finishes
  • Available in sets for single or double doors
  • Can be fitted directly over hinges with no hinge binding
  • An alternative version with twin rubber blades is available for larger gaps and distorted doors
  • Independently tested to BS476 Part 22 (1987)
  • 60 minutes of fire integrity – even with a gap of 11mm at the head of the door!
  • Intumescent paper supplied for locks
  • Supplied with “FIRE DOOR – KEEP SHUT” self-adhesive labels and panel pins

Fitting these seals will greatly reduce the risk of serious injury and minimise fire damage, preventing fire and smoke from penetrating into escape routes. Firewise is your one-stop shop for passive fire prevention products, from door upgrades to complete refurbishment and new building fire solutions.

 

DESCRIPTION

A surface-mounted intumescent fire seal or fire/smoke seal available in black, brown, red, white, and real wood veneer finishes. No routing is necessary. Supplied with intumescent paper for use around lock and hinge areas and two labels printed “Fire Door – Keep Shut”.

USE

This product can be fitted to door frames in minutes. A 3.5mm or greater gap down the closing stile and across the door head is all that is required. Seals fit directly over hinges with no
hinge bind and no special gap is necessary on hinge side.

Once fitted, the face of the seal can be painted, although the brush smoke seal must NOT be painted. If the brush is painted in error, it is easy to replace. Pins are supplied for pushing into the brush seal, although the brush has a self-adhesive strip at the back.

PERFORMANCE

In a test on an old door with a head gap between 7mm and 11mm, the seal just expanded and remained in place for the whole test. Tested to BS476 Part 22 (1987), achieving an integrity of up to 66 minutes with an 11mm gap at the head of the door.

The intumescent strips included have also been successfully tested to BS476 Part 23 (1987).
