paint iconPerfect Finish

All our windows are finished to an immaculate standard, sprayed with four coats of microporous paint or stain in our factory. You can choose from a painted, stained or clear lacquered finish.
You can also choose to have dual colours, for example: white on the outside and a colour sympathetic to your interior inside. Your windows will be fully finished with no need to paint after installation, and providing they are well maintained they will not need re-painting for an average for 10 years.
For the colour conscious client, we also offer colours from Farrow and Ball’s® paint range. See our paint and stain options for more details.

Heritage iconHeritage Casement Windows

Our heritage profile casement windows are designed to preserve the period aesthetic of your property, while still benefitting from the latest in thermal technology. Our heritage casements have a slimmer opening sash than our modern casements, they are particularly suited to properties subject to Article 4 Direction conservation area requirements and especially listed buildings. The use of a slimmer sash maintains the aesthetic of a period single glazed casement window, but with all the benefits of a modern double glazed window. Our heritage profile windows can also be made with proud frames (where the frame sits proud of the opening sash), common thought-out homes built in post-war Britain.
Our heritage profile casements come with traditional butt hinges, and a choice of casement fasteners & stays.

Casement window iconFlush Casement Windows

The Sashed modern flush wood casement windows are designed with tradition in mind, by using the latest technologies we adhere to the highest thermal and acoustic performance criteria. The flush design is characterised by an opening sash that sits level with the frame. Externally, this gives a completely flush finish to the outer elevation of the window.
