Aluminium Bifold Doors — London & the Home Counties
The traffic-door leaf
One leaf on every set works as a hooked single door — same handle, same key, no need to fold the whole run open to step out for the bin. It's the difference between a bifold you love in July and one you love in November.
Overview
Concertina open your kitchen to the garden. Our aluminium bifolds run on precision German rollers, glide with one finger and span up to 7 metres — bringing outside living within reach for even modest British homes.

Practical answers.
Everything homeowners ask us about bifold doors — survey, lead times, guarantees and coverage.
How wide can bifold doors go?+
Our systems span up to 7m in a single run and up to 12m across a corner. Beyond that we specify a slim-frame slider or a combination — we'll advise on the right choice at survey.
What U-value do aluminium bifold doors achieve?+
Our thermally broken aluminium bifold doors achieve whole-door U-values of 0.9–1.4 W/m²K. We confirm the exact glass, frame and threshold specification for each London and Home Counties opening.
Are they secure?+
Yes. Our bifolds carry multi-point shootbolt locking on every panel, laminated inner glazing, and PAS 24 accreditation. The traffic door has its own hooked multi-point mechanism.
Should the panels fold inside or out?+
Out-fold is standard because it keeps the internal space clear. In-fold is specified when a canopy, porch or overhang prevents outward opening. We survey the reveal and advise before manufacture.
What affects a bifold door specification?+
Opening width, panel count, traffic-door position, threshold, colour and glazing all shape the final design. We confirm each detail after checking the structural opening on site.
