Revisions log for Answer #2563

There are at least 7 manufacturers (groups) of PVC window profiles in Germany. These include:

— Rehau

— Veka / Gealan

— Profine (Kömmerling / Trocal / KBE)

— Salamander / Brügmann

— Schüco

— Aluplast

— Inoutic (formerly Thyssen).

They supply their profiles to window manufacturers. Some window manufacturers assemble the windows themselves, others sell their windows to resellers/dealers who install the windows. Some window manufacturers or dealers assemble them with their own people, and many do window replacements.

Thus, on the way to a quality-assembled window, carefully made from strong profiles, with durable hardware and flawless glass, there are still many unsightly moments.
