Flush Casement Windows

The principle is very simple. We take the appearance of a traditional window frame, its proportions and its sightlines and we replicate it. We add all the extra features: period hardware, ancillaries, cills and glazing bars. We select period colours and finishes. To that we add the benefits of 21st-century, easily maintained materials, weatherproofing, thermal and acoustic insulation, and security.

Fabframes Defendoor

We’ve studied all the finer details of historical window design, but we haven’t forgotten that someone has to fabricate and install these windows. We made it part of the design brief that these windows should be easy to live with and to work with. Our Flush Casement suite is compatible with other components from our Optima range so that your stockholding is easier to manage.

The whole of the Optima range is made to the highest possible standards using advanced technology and tooling. Not only does this ensure superb surface finish, but also precise dimensions, wall thickness and internal webs. Hardware is easy to locate, drainage is optimised and seals perfectly placed for long-lasting performance. The system surpasses the requirements of UK and EU Building Regulations and PAS24 and is accredited by the British Standards Institute.

The Optima difference

There are other flush casements on the market, but in developing Optima, we’ve refused to compromise. Optima Flush Casements replicate more accurately the original features of timber casements and at the same time, give superior thermal performance over rival products. They look better and insulate better, and that’s the Optima difference.
