Dempsey Dyer Beaumont Composite Window

The Beaumont window from Dempsey Dyer has been designed to bridge the gap between uPVC and timber products. KJM believes this product is an excellent addition to our range, as its a uPVC window with "timber looking joints".  The Beaumont has hand-crafted joints and this jointing system sets the window apart from other conventional uPVC windows. The product is currently only available as a casement window, there are no door options for this system.

Our manufacturers two main areas of concern were its structural integrity and weather tightness. There are two British Standards that are relevant to these areas which we now have indicative test results for on the Beaumont Window.

  • BS7950 – stipulates each corner and every locking point must pass a load of 3KN. The Beaumont Achieved 7KN.
  • BS7412 – has no minimum requirement rather a rating and the Beaumont achieved 600PA.
