Timber Window Services

Traditional Wooden Box Sash Windows
Our conventional box sash windows are designed to replicate the traditional form, to keep in line with period properties and conservational area appearance. Our improved insulation minimises condensation, draughts and heat loss in comparison to single glazed sash windows and can look identical to the windows you are looking to replace. By using engineered timber, this allows us to make frames slimmer and lighter with the use of modern interpretations of the cords and counterweights for improved functionality.

Traditional Wooden Slim Box Sash Windows
Our Conventional Slim Box Sash windows are ideal for replacement windows where internal shutters or decorative features restrict the depth of new windows due to the slim design. This design is also perfect for bay window replacements and they are quickly becoming one of the most popular window types in the U.K. In addition they are ideal for conservation areas as the sash horns and glazing bars are available in different widths to match existing window designs.

Traditional Wooden Flush Casement Windows
Traditional Flush Casement Windows are the easiest way of restoring the traditional look to older houses or adding character to new properties. They are beautifully designed to complement and add value to your home. They offer the same benefits that uPVC windows can but with the use of engineered timber for a classic look.

Contemporary Wooden Flush Casement Windows
Our Contemporary Flush Casement Window is a traditional window design that has been revamped for a more modern look. The design is incredibly simple and perfect for adding individuality to a period refurbishment or for allowing natural light into a barn conversion.

Wooden Tilt & Turn Casement Windows
Tilt & Turn windows have been designed using a dual hinge system, and are increasingly used in modern buildings and apartments due to the functionality and ease of cleaning. These windows look very modern and are highly practical at the same time. With a choice of opening, Tilt & Turn windows are higher in demand than ever and we put it down to the versatile design.

This includes but is not limited to centre pivot Velux windows, top hung Velux windows, integra roof windows, sloping and vertical combinations, Velux cabrio balcony and roof terrace windows.
