PVC systems
We produce our PVC joinery on Kömmerling systems, a German profile manufacturer within the profine group. Below are the systems we work with routinely, with the data published by the manufacturer.
Each system page carries the official specifications of that version. Where the manufacturer publishes a downloadable data sheet, you will find it on the page; where it does not publish one openly, we have put a direct link to its system page, so that every figure can be checked at source.
We have not carried values over from one version to another. If a system does not declare a particular characteristic, it does not appear on the page.
