Flush Casement Window

The Optima Flush Casement Window replicates the original features of timber casement windows more accurately than rival products and gives superior thermal performance too. It means you can open up heritage opportunities across all sectors.

Every detail of the Optima Flush Casement Window has been designed from scratch to deliver impressively authentic period looks with market-leading performance. Features and options include mechanical jointing, a dummy sash to give a balanced look, a deep bottom rail to replicate original timber frames and authentic hardware including monkey-tail handles and dummy peg stays. Colour options include period colours and dual colours.

All-in-all, it means there's a compelling PVC-U option for heritage homes, social facilities, commercial premises and places of work.

And because its an Optima window, the end user benefits are just the start. There is also a wealth of benefits for fabricators and installers. These include common ancillaries for reduced stockholding, easy-to-locate hardware, optimised drainage and perfectly positioned seals for long-lasting performance.

As well as recreating the traditional British cottage window, the Optima Flush Casement Window also has a French Flush Casement Window option. The combination of the flush appearance and outstanding weather protection deliver an unbeatable result.
