Clement now manufacture Jansen cold formed steel systems

November 6th, 2023

Clement is excited to announce that it is now able to manufacture and install cold formed steel systems by Jansen.  The slender Jansen steel window profiles meet the highest thermal, security and fire protection requirements and are suitable for restoration work and new builds.  Jansen steel door profiles are appropriate for situations where higher levels of safety, insulation and soundproofing are required, but where slim steel frames are still desirable.


Clement was selected to supply and install the custom made steel windows and door screens used for the shop fronts on the ground level at 90-104 Berwick Street in London’s Soho Conservation Area.  The site has recently been transformed from an unattractive 1950s block into a stylish, contemporary mixed-use development with a combination of fenestration products.  These include Clement W40 steel windows which sit beside and above the doors, the Jansen Economy 50 range of single and double doors and the Jansen Economy 60 range of bi-fold doors.

More case studies can be viewed here, together with further information about the Jansen products we manufacture.
