Flush Casement Windows offer authentic period looks – ideal in heritage restorations where equal sightlines are required – while their classic styling means they’re equally perfect for modern projects.

Every detail of our Flush Casement Window has been designed to deliver authenticity combined with market-leading performance. Features and options include mechanical jointing, a dummy sash for a balanced aesthetic, a deep bottom rail to replicate original timber frames and traditional hardware including monkey-tail handles and dummy peg stays.

Our wide colour range includes heritage shades and dual colour options, so a traditional or contemporary result can be achieved, simply by specifying a different colour, hardware or glass option.

There’s 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.
