Optio BSC94 Lift and Slide Door

AluK Door to a balcony in a stylish apartment in Cardiff

Why Choose Our AluK BSC94 Lift and slide doors?

This premium multi-configuration Lift and Slide system delivers an effortless operation along with excellent thermal performance and very slim sightlines.

Lift & Slide doors sit directly on the track, and the sliding panels are raised onto the rollers using a mechanism in the door handle. The result is an effortless, smooth operation that is not affected by the weight of the door. AluK’s BSC94’s Lift and Slide technology can support panel weights of up to 400kg, resulting in greater design flexibility and heightened operator comfort.

Slim Sightlines, Maximum Performance

Manufactured to the highest UK standards, this multi-configuration sliding door system offers high thermal performance with U-values of 1.7W/m2K (triple glazed) and a wide range of customisable options.

The slim sightlines highly desirable today can be achieved with two options: the standard 100mm or the ultra-slim 45mm option. This measurement relates to the interlock – the vertical aluminium profile between each panel of glass.


The BSC94 Life & Slide Sliding Door combines high performance with a contemporary, minimal design. This multi-configuration system provides outstanding thermal U-values of 1.7 for triple glazing (dual rail) and has a BRE Green Guide Rating of C.

This sliding door system achieves solid wind (Class C3 - 1200Pa), water (Class 7A - 300Pa)  and air tightness (Class 4 - 600Pa) test results and is fully certified to PAS 24 and Secured by Design for maximum security.

The maximum frame height available is 3000mm, and the maximum vent width is 2000mm, allowing you to achieve the large expanses of glass that create a modern, minimal aesthetic.
