S140 Lift & Slide Door


Folding and Sliding Doors


The slim sightlines of the new S140 Lift and Slide mean more glass and less frame -  opening up the views to the outside and letting more natural light flood in.
The flush sash aesthetic gives the door a minimalist, contemporary look which appeals to retail buyers and developers alike, and it offers maximum configurability so that it can be used in applications from high end homes to high rise apartments.
There are double and triple track frame options available with the 140mm frame depth, a choice of double and triple glazing, and capacity for thicker acoustic glass if required.
There is no compromise on performance either – the S140 can achieve impressively low U-Values of just 1.2Uw double glazed and 0.8Uw triple glazed, it boasts excellent wind and water resistance and air permeability scores.
