CWS-65 Slim

Our ultra slim steel window and door system offers you the same thin framing you would expect from a traditional steel window but with a full thermal break for enhanced thermal insulation.

Steel framed windows and doors offer you a timeless elegance and although they are having a resurgence in modern architecture they never truly go out of style. The Mondrian® CWS-65 Slim has the slimmest framing possible from a thermally efficient steel windows system. The system is made from true cold rolled steel profiles with a two-part thermal break separating the inner steel section and the outer section.

Even with a thermal break, the steel framing is impressively slim, offering a true steel window design for your project at a depth of 65mm. The frames are available in a traditional galvanised steel frame which is powder coated to any RAL colour of your choosing. But you could also opt to have the same frames in Stainless Steel, Corten Steel or Architectural Bronze.

Whether you are looking to replace traditional, low performing steel windows, to replicate a steel window design on a historical building or creating a beautifully modern industrial design, the Mondrian® CWS-65 Slim will offer you the best solution.
