Fire Rated Glass Door

The SG20 is a versatile, slimline steel and glass door, with matching glazed screens and windows. When used as main entrance doors to public and commercial buildings, the SG20's welded steel construction is capable of withstanding very heavy use over many years. When used internally, the fire rated SG20 is often used in corridors, stairs or lift lobbys in multistory buildings.

Fire Rating

Our SG20 doorsets have been tested to BS 476 or BS EN 1634 and have achieved integrity ratings from 30/0 to 180/0, and integrity and insulation ratings from 30/30 to 90/90.

Size limitations do apply, so please contact us for further advice to achieve your required specification.
