Welcome to Knelsen GmbH

The Knelsen GmbH was founded in 2004 and specializes in developing and producing fasteners for highly efficient energy-saving window systems. We offer you the load-bearing connection in every assembly situation!

In the area of structural insulation, the requirements for heat protection / energy-saving ordinance have changed significantly in the recent years. The insulation layer has doubled or rather tripled. So it is often not possible to accomplish a professional assembly with conventional fasteners. We have developed the K-Universal anchors as an innovative assembly solution for this problem.

Our portfolio not only includes window fasteners for assembly inside the reveal and in front of the facade, but also window sill brackets and fasteners for roller shutter boxes. We offer competent technical advice and custom designs, which are suitable for your assembly situation. Furthermore we host trainings for topics like window installation and fall protection. Assure yourself of our quality products and contact us.
