Aluminium Doors FAQ

Q: What is the minimum & maximum width per door?

Minimum
400mm if there is an odd number of doors folding in one or both directions, 700mm is there is an even number of doors all folding one way
Maximum
1200mm per door leaf

Q: What is the maximum height of the doors?

2500mm is the maximum overall height (including the frame). We can go higher however the door would then only come with shootbolt locking and no multipoint lock, therefore less secure

We offer a specially selected range of 7 bespoke colours plus 3 natural wood effects. Additionally, choose from the full range of Interpon RAL colours oak & mahogany.

Q: Are the doors top or bottom hung?

Our doors run on the bottom track and are guided by 2 wheels at the top.

We have 2 threshold options, our standard threshold comes with a severe weather rating and we would recommend this for external use. Secondly, our low threshold which we would recommend for internal use only as this is not weather proof

No, the running gear is concealed with the bottom track.
