Ali SLIDE is a slimline, high-performance range of inline aluminium sliding doors with PAS 24 security. This stylish, mid-range, sliding door has been designed to fit all budgets and is suitable for both domestic and commercial use.

Ali SLIDE is available as both a Standard version with a 79mm interlock and as a Slimline version with an interlock of just 50mm to give maximum daylight and uninterrupted views. Both versions use the same locking hardware, which is why the Slimline version can also achieve PAS 24.

Ali SLIDE doors have a polyamide thermal break to give impressive thermal efficiency with U values as low as 0.9 W/m2K and are fully weather tested.

Like our Ali VU windows and Ali FOLD doors, the most popular configurations of the Ali SLIDE door are available in pre-painted stock of 7016 Anthracite Grey and 9910 Hipca White, for immediate delivery within 3-5 days.
