The SL800+ is a slimline sliding door system. It has superb energy efficiency to meet Carbon Zero Passivhaus standards to support homes achieving a high level of comfort but using very little energy for heating and cooling. Its exceptional thermal efficiency makes it the ideal choice where rooms face prevailing weather systems, and with Uw values from 0.76 W/m²K, it will benefit your home’s energy efficiency all year round.

Frame visibility for the SL800+ is minimal – sightlines are only 34mm to create beautiful frameless sliding doors, complemented by discreet continuous handle design. The system has extraordinarily strong aluminium frames capable of supporting panels up to six metres high and weighing up to 1000kg for a truly architectural installation.

This is the ideal system for post-free corner sliding doors and pocket installation to achieve that seamless transition to the outside. These slimline glass doors can be flush-mounted to maximise that essential indoor/outside flow and the high specification steel carriage sliding mechanisms ensure that even the largest slimline doors we manufacture open effortlessly and smoothly with minimum applied pressure.

The SL800+ is exceptionally secure and comes with alarmed glass and bullet-proof glass as options. It can be connected to high-level control and security monitoring systems for complete peace of mind. It offers a high level of sound insulation and like all our sliding systems, can be finished with solar control coatings appropriate to your room’s orientation.
