The SL800 is a slimline sliding door system. If you are looking for large sliding doors with superb energy efficiency, the SL800 will deliver in style. Minimal aluminium frames ensure huge expanses of glass for a truly spectacular installation. The SL800 offers individual panel sizes up to 4 metres high and 3 metres wide, while our SL800+ can be specified in panes up to an extraordinary six metres in height. Frame visibility for this SL800 is minimal – sightlines are only 34mm to create beautiful frameless sliding doors, complemented by discreet continuous handle design. This is the ideal system for post-free corner sliding doors and pocket door installation for homes where transition to the outside needs to be seamless.
These external sliding 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.
Despite its size, this aluminium sliding system has unrivalled performance. Its exceptional thermal efficiency makes it the ideal choice where rooms face prevailing winds and weather systems, and is advised for homes on frontline coastal locations. In addition, the 800+ meets Passive Haus standards with Uw values from 0.76 W/m²K – it will benefit your home’s energy efficiency all year round.
The SL800 is exceptionally secure and 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.
