About us

Since Knelsen GmbH was founded in 2004 by twin brothers Anatoli and Waldemar Knelsen, the family business has specialised in the development and manufacture of window fixings for energy-efficient window systems.

Waldemar Knelsen started out as a window fitter back in 1990 and was repeatedly faced with installation situations that could not be solved with conventional fixing materials. He then developed solutions that could be tested and applied directly on the construction site. His brother Anatoli Knelsen joined him and together they further developed the products. Our range now includes not only fasteners for windows in the reveal and in front of the façade, but also window sill brackets, installation aids and fastening systems in roller shutter boxes.

Today, we are characterised by our practice-oriented customer advice, a wide range of products and their pragmatic use. The continuous development of these products and our company is particularly important to us. In addition to our headquarters in Salzkotten, we now have further locations in Poland, Russia and, since 2021, a branch in Belgium.

We are happy to offer you expert technical advice and customised products to suit your installation situation. Since 2017, we have been offering training courses on topics such as window fastening and fall protection. You are welcome to see our extensive range for yourself and get in touch with us. We will be happy to help you.
