Aluminium Sliding & Patio Doors

Inline doors run on rollers and move with a straight push. Lift-and-slide doors lift the sash off its seals on the handle turn, glide, then drop to compress the seals shut. Lift-and-slide suits heavier sashes, up to 2.2 m by 2.87 m and 420 kg where specified, and seals firmer. We confirm the action at quote.

Two-track and three-track configurations in 2, 3, 4 and 6-sash layouts, sliding to one side or splitting from a central meeting point. A 35 mm slim interlock keeps central sightlines narrow, and pocket runs slide sashes into a wall cavity. Track count drives stacking and clear opening width. See our sliding door range.

Sashes run up to 2.2 m by 2.87 m at up to 420 kg where specified, with the achievable figure set by glass make-up and roller rating. Glazing spans 24 to 48 mm, including double, triple, laminated and integral-blind units. We confirm sash dimensions, weight and the rollers required when we prepare your quote.

Whole-unit U-values run from 1.0 W/m²K where specified on lift-and-slide routes, with triple glazing up to 48 mm. Weather ratings reach air permeability Class 4, watertightness to Class 8A and wind resistance to Class C5. Acoustic reduction runs up to 45 dB. Confirm the whole-unit Uw at quote. See energy efficiency.

Standard upstand thresholds for weather performance, or low thresholds and floor-recessed tracks for level, step-free access. Tested-security routes are available where required. Corner posts let two runs meet at an open corner, and a moving corner post slides clear so both runs open fully. See security or ask a vetted installer.
