Aluminium lift and slide patio doors create wide openings with large expanses of glazing. They are the perfect choice when you want extensive and panoramic views of your garden or exterior space. The KLS lift and slide patio door system provides end users with an effortless opening action with every operation. It slides smoothly open and can be securely locked to protect any property interior.

KLS patio doors are compatible with domestic and commercial applications. They can even be used as an openable partition between two interior areas. Mechanical cleats and chevrons are used for ease of fabrication and the door’s heavy-duty sliding roller system can support individual door leafs up to 3300mm x 3200mm in height. The system’s maximum weight capacity is 400kg and each section is internally beaded to maximise security.
