Knudsen Wedge


Secure, fast, inexpensive

building assembly


The Knudsen wedge has been used by the Danish building industry for more than 40 years - for the last 25 years the wedge has been made of plastic, which is how we know it today.

Knudsen Kilen A/S is a modern company that develops and produces a series of plastic items of high quality for the building industry. All our products are made in accordance with ISO 9001 : 2000.

As well as producing wedges, we are also involved in a number of cooperative projects concerning improvements, new developments

and production planning.

We carry out tests on an ongoing basis in cooperation with the Technical University of Denmark and other partners.

In addition we are available to assist with:


  • Contacts with architects
  • Information on step sound
  • Information on pressure loads
  • Requirements assessment
