Sliding Doors For Extension

A glass extension with sliding doors

This home in South West London extended, improved natural light and provided better links to the garden thanks to a glass extension with sliding doors.  

Keller minimal windows sliding doors were used within the frameless structural glass extension by IQ Glass. Set within the west elevation of the glass extension is a set of minimal windows. The sliding glass doors were installed into the structural glass assembly to provide the much needed link from the house to the garden.

The minimal windows were chosen as the sliding doors for the glass extension due to the slim nature of their frames. The structural glass extension was designed with a fully frameless aesthetic. Slim framing was required to the sliding doors to continue this design to the patio door design.  

A steel ‘goal post’ design was used for the west elevation of the glass extension with sliding doors fitted into this opening. Externally, the steel of the glass extension was covered with back painted glass to merge this solid structure into the sheer faces of glass.

A two pane minimal window was used for the glass extension sliding door. A typical internal lock was used operated via a thrust lever handle (the type 2 lock). The locking operation sits within the slim leading edge of the sliding door to minimise its impact on the visual design.  


Using a dark finish to the sliding doors complemented the black silicone joints of the structural glass box and the black sheer glazing that surrounded the door opening.
