Product overview
Full-width openings with slim-sightline bifold panels
Aluminium bifold doors use a concertina action to fold and stack panels neatly to one or both sides of the opening. With sightlines from just 107mm and up to 14 leaves available, they maximise glazed area and create a seamless connection between indoor and outdoor spaces — a defining feature of modern residential extensions and kitchen-diners across London and Essex.
The 70mm thermally broken profile system incorporates a 34mm polyamide break, significantly reducing heat loss. Argon-filled double or triple glazed units achieve U-values as low as 0.7 W/m²K with TGU. A traffic door is included as standard for everyday access without opening the full set. Flush threshold options are available for level access between inside and outside.
All panels are finished in T5 powder coat in any RAL colour — satin, gloss or matt. Multi-point locking on the traffic door with shoot bolts on all other panels. CE marked to EN 14351-1. Supplied bespoke to your exact dimensions with an 8–10 week lead time. We supply to homeowners, architects, builders and developers across London, Essex, Hertfordshire, Kent and Surrey.
