The Fech-Jet-System® can be installed in most standard sandwich facades. This can be done irrespective of wheter the window opening has been created via structural measures or via retrospective cut-out.

Depending on the sandwich profile, the profile spaces between frame and sandwich panel are reliably sealed by means of differently moulded special seals.

Thanks to the adjustable aluminium outer frame, the window system is suitable for sandwich panels in all standard thicknesses form 40 to 160 mm as well as for many different windo structures.
