Penthouse Plus Sliding Patio Doors

Penthouse Plus Aluminum Sliding Patio Doors

Our Penthouse Plus S (Slide) and Penthouse Plus LS (Lift & Slide) are large sliding patio doors offering maximum glass and minimum frame, dramatically increasing the natural light into a room. Constructed from strong thermally broken aluminium profiles they can achieve U-values as low as 1.6 W/m²K and high weather performance; making them suitable for use in exposed locations. Huge glass panels up to 2.5 metres wide provide unobstructed views of the world outside and the panels slide with ease.


Our 'Penthouse Plus' has a specially designed threshold enabling them to be dropped into the floor, to bring the internal floor level flush with the top of the threshold; negating any step over, and minimising any trip hazard. All panels can be made to slide and a triple track system with three panels can achieve approximately a two thirds clear opening. Fill your property with light & make the most of a beautiful view with these superb sliding doors.
