Overview
More glass, less frame
Aluminium sliding patio doors glide open along twin or triple tracks, bringing in daylight and opening your home to the garden without taking up floor space. Slim aluminium frames maximise the glass area while remaining strong and secure.
Choose a low threshold of approximately 30 mm for easy access, or a raised threshold for exposed, rain-prone locations. Standard or thermal break profiles are available.
Security comes from a claw-locking system and toughened or laminated glass.
