QUAD SEAL - Installation Guide
Introduction
Introduction
The purpose of this document is to give guidance to approved contractors
and suppliers who are engaged in the fire stopping of fire rated structures
using Astro Quad Seal. All Timber fire door assemblies must be fire stopped
to prevent the passage of fire, smoke and hot gases. The key points for
passive fire protection products are :-
-
Prevent the spread of fire, smoke and hot gases through a building by containing it in the
-
compartment of origin
-
Maintain the integrity of escape routes from a building.
-
Reduce loss or damage to property from the effect of fire and smoke.
-
Maintain pressure differential between compartments and ventilation channels.
THE ASTRO QUAD SEAL SYSTEM
Quad Seal is an intumescent Fire, Smoke, Acoustic & Thermal seals
for fire door assemblies
The
seal is constructed form an Astro intumescent graphite based fire seal
combined with a Schlegel Aquamac Smoke, Acoustic & Thermal seal all
contained within a PVC sleeve.
It fits into a rebate to either the leaves or the door frame.
In the event of a fire, the seal expands (intumesces) to many times its original volume and seals the gap around the door to provide a safe and effective barrier against the passage of fire, smoke and hot gases.
Supplied in 2100mm lengths with a self-adhesive backing tape to facilitate quick and easy fitting. The seals are available in a choice of colours to suit your requirements or blend with decor.
Passed at BS 476 part 22 & 31 for 30 or 60 minutes rating Certifire
approval
Smoke seal to 100,000 cycle test
NHBC Type Approval.
Astro Quad Seal is passed and certified for use in single and double door
assemblies (single and double action), and can provide fire and smoke
resistance in excess of either half an hour or one hour.
If your fire door or frame is not pre-grooved check the door manufacturers data and test sheets to establish the size and quantity of intumescent seals required.
You should also note the tested position of the seals and whether any additional protection is required around the particularly vulnerable areas of the lock and hinges (see Astro Protecta).
Rebate the door or door frame to accommodate the chosen seal which should be fitted so that the PVC sleeve finishes flush with the face of the timber.
An allowance in the rebate width may be necessary to allow for timber shrinkage or for paint/stains, so we recommended grooving 3% greater than the chosen seal size. We recommend that the gap between door and frame should be no greater that 4mm.
To fix remove the release paper from the self-adhesive backing tape and push the seal firmly into the rebate along its full length. For alternate fixing methods use Astro Intumescent Mastic or steel pins
If the door or frame is to be painted/stained care should be taken to ensure the paint/stain does not come into contact with the Schlegel Aquamac seal. Periodically check the combined Astro intumescent seal & Schlegel Aquamac seal to confirm the integrity.
