Beaumont Composite Windows

Developed by Dempsey Dyer, the Beaumont composite window features an innovative jointing system that rivals the aesthetics of a traditional timber window whilst featuring all the benefits of a PVCu window.

The Beaumont composite window utilises mechanical joints on both the frame and sash making this the first window to do so that features a stormproof casement sash.

As with all our product offerings we’re able to tailor this product to meet your requirements. A comprehensive range of styles, ironmongery and finishing options can be utilised to create a highly bespoke solution. Foiled finishes come as standard to achieve true timber aesthetics.

BFRC Window Energy Ratings – Our PVCu open out casement windows are registered with the BFRC under the window energy rating scheme. As our Beaumont composite window solution utilises the Deceuninck 2800 profile, we are currently able to offer our customers the most efficient rating available under this scheme – an “A” rating.

We are also able to simulate any glazing specification with our product range to prove its thermal performance (whole frame U-Value).

Our Beaumont composite windows are supplied with shootbolt and mushroom adjustable cams. With our espagnolette featuring an impressive salt spray corrosion resistance you can be sure our products are manufactured to last.

When you are pushing the boundaries of any product, it is important to ensure there are no ill effects to other areas of the design. In this case, the improved sash corner aesthetics meant a complete new jointing system had to be created which then must be proved to be at least to the same performance as a welded joint.

Our 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.
