Ecoline bi-folding door
A wide choice of floor tracks, openings and colour options, with only a 99 mm frame sightline
With a building depth of 67 mm, maximum panel width of 1 metre and maximum height of 3 metres, the aluminium Ecoline bi-folding door system boasts an unbroken, slim sight line of 99 mm at the panel joint.
This is thanks to the heart of the bi-folding door: the bionicTURTLE®, a multi-functional break profile that houses the locking mechanism and the fittings while keeping the profiles exceptionally slim.
The Ecoline bi-folding door is PAS 24:2016 certificated.
