Durations Aluminium Doors
The Duration Alitherm aluminium doors are a very popular product of ours here at Duration and match the Duration Alitherm windows and our aluminium bi-folding doors.
The Alitherm range of doors and windows offer slim lines, modern locking and great looks. Using modern technology they are thermally efficient, strong and secure. They come with a wide range of furniture, colours, thresholds and glass - to suit any home.
Due to their modern design features, these doors comply to Document L for new build, refurbishment and extensions in dwellings and non-dwellings.
Features
- Various configurations of glass and solid panels are available, such as glass in the top and panel in the bottom, glass top and bottom, or a single panel. Many panel designs are available to view - see the Downloads section on the left side of this page.
- The optional Low Threshold greatly reduces the step-over required.
- Hook locks at top and bottom of the door, plus the dead-latch, firmly secure the door to the frame. The hook locks literally hook into the frame, preventing the door from being lifted upwards.
- Slim-line butt hinges on our aluminium doors are a lot slimmer than uPVC door hinges.
- Handles in a variety of colours and styles compliment the door.
