Frequently asked questions
Which track should I choose?
Use the flush track for barrier-free interiors, the high track (45 mm) where water and dust resistance matter most, the floating track (65 mm) for a premium look with strong sealing, and the lift track for lift-and-slide operation.
When do I need the reinforced interlock?
Use the standard interlock sash for door heights up to 2.6 m and the reinforced interlock above 2.6 m.
Do you supply accessories with the profiles?
Yes. We supply rollers, seals, brush strips, corner pieces and hardware matched to each track, so you can order a complete kit.
What is the difference between the double-track and triple-track frame?
The double-track frame is 106 mm deep with 2 tracks and 2 platforms and needs 4H + 2W of sash per door; the triple-track frame is 159 mm deep with 3 tracks and 3 platforms (2 + 1) and needs 6H + 2W. Both share the 52 / 65 / 75 mm sash and the 18 mm interlock.
