Slim XL Sliding Doors

Sieger Systems

The system outperforms the competition for both design and performance. This enhanced version of the standard Slim Slider holds a triple glazed unit in sliding panes of up to 4m wide or 4m tall.  There are a broad range of sliding configurations possible from a single pane sliding pocket door to a six pane opening corner sliding system. And of course, automation is available.

The XL version of our Slim Sliding Doors offers a higher level of performance both in strength against wind loading and insulation. The 25mm frames hold a triple glazed unit as standard which allows you to achieve much higher levels of thermal insulation.

These large format sliding glass units can be made in impressive sizes of up to 4m tall or 4m wide per sliding pane. Automation is recommended if the sliding units weight more than 400kg to make the system manageable with an overall maximum unit weight of 700kg.

There are many sliding configurations possible from pocket doors to opening corners. Linear elevations of the XL Sliding Doors can be up to 3 panes sliding in one direction. For a longer elevation of glass you can specify the sliding panes as bi parting and create a single elevation of sliding glass up to 6 sliding panes wide.

The XL Slider also has a unique base option which allows the floor finish to continue right across the base from inside to out. This even further blurs the division between inside and out.

Further information about this system and costing can be obtained by contacting a member of the Sieger team.
