Optio BSC94 Lift and Slide Door

Aluminium sliding door with a great garden

For those looking for effortless operation, look no further than our premium aluminium lift and slide door


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 raise the sliding panels 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.


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 sliding door is available in mono, dual and triple rail options to suit your design and fit the available opening space.

Available in single or dual colour polyester powder coating, texture, and anodised finishes, you have all the design freedom you require to create a truly unique space.

The BSC94 Life & Slide Sliding Door combines high performance with 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, water and air tightness test results, and is fully certified to PAS 24 and Secured by Design for maximum security.

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

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 the modern, minimal aesthetic.
