Aluminium Sliding Patio Doors — London & the Home Counties
Where bifolds fold, sliders disappear. For an uninterrupted view of the garden all year round — and glass panes up to 3m tall on a single leaf — nothing beats a slim-frame aluminium slider.
The 20mm interlock
Where two sliding panels meet, conventional systems show a 60–70mm frame stripe blocking the view. Ours meet at a 20mm interlock — a hair-thin vertical line at eye level that all-but-vanishes when you're looking through it.
Overview
A closer look at what makes the sliding doors range distinctive — the specification, the styles, the process, and the answers to the questions we get asked most.
Thermally-broken aluminium profile · precision stainless roller carriages · Q-lon weather seals · A-rated argon glazing · PAS 24 multi-point hook locking
20mm Interlocks
The slimmest sightlines available on the UK market — maximum glass, minimum frame, minimum visual interruption.
Huge Panes
Individual panels up to 3m tall and 2m wide. Perfect for garden-facing rear elevations and view-driven coastal or lakeside homes.
Glide-and-Lock Mechanism
Precision-engineered stainless rollers plus multi-point hook locking. Silent to open, immovable when closed.
Lift-and-Slide Option
Premium gear where a single handle rotation lifts a 400 kg panel a millimetre off its track — allowing effortless slide on the largest configurations.
Flush Threshold Available
Weathered sill as standard or a fully flush level threshold for barrier-free access to the garden.
Three material ranges, one configuration.
The sliding configuration is available across every one of our door ranges — the material choice is yours.

Practical answers.
Everything homeowners ask us about sliding doors — survey, lead times, guarantees and coverage.
Sliders or bifolds?+
Sliders keep the view open all year round and provide strong thermal performance in winter. Bifolds fully open the wall in summer. Many clients specify sliders on shaded elevations and bifolds where they entertain — we'll walk through the trade-offs at survey.
How large can a single sliding panel be?+
Up to 3m tall and 2m wide on our premium lift-and-slide system — around 400 kg of glass moved on a single handle. Bigger than that and we specify a fixed picture window alongside.
Are they warm?+
Yes — 1.2 W/m²K on a thermally-broken frame with argon-filled A-rated glass. Modern sliders are as thermally efficient as a solid wall of the same era.
What's a pocket slider?+
A configuration where the sliding leaves disappear entirely into a wall cavity, leaving an unobstructed opening. Requires a plasterboard-lined wall pocket at build stage — we survey and detail this at design.
