Fletcher Joinery - Tranditional Joinery Manufacture of wood windows, doors, staircases , conservatories and more..

A sash window or hung sash window is made of one or more movable panels or "sashes" that form a frame to hold the panes of glass. The window panels are opened by sliding vertically, or horizontally in a style known as a "Yorkshire light", sliding sash or sash and case (so called because the weights are concealed in a box case).

Sliding sash box windows generally have a reputation for being draughty and cold, but we greatly reduce these problems by building in a draught excluder to the opening sashes. We generally use double-glazed glass with 20mm thick (4/12/4) thermally-coated, argon-filled, double-glazing units to comply with the new "Part L" building regulations. We can also use a narrow glazing bar system if required.

We are able to manufacture to match existing windows on listed buildings and in conservation areas where the new "Part L" regulations may not apply.

The sashes can be hung using either traditional cords and weights or the more modern spiral balances.

The timber we use is usually top quality selected Scandinavian redwood (also known as softwood or pine). Other timbers which are commonly used for these windows are Douglas fir, American or European oak and mahoganies such as Brazilian, sapele, luan, or meranti, etc.

Our windows are constructed and then dipped in a clear wood preservative. By dipping the windows after construction, all cuts and edges are treated, which would not be the case if the components were treated before manufacture. This preservative will accept either paint or stain after it has dried. If required, a further protective treatment of a water sealant can be applied to reduce expansion and contraction in very vulnerable locations.

Timber sections to match your requirements or our traditional standard profiles are used. The frame is trenched together and all sashes are morticed and tenoned with scribed joints (not routered) to form a sharp internal corner. Traditional box windows are normally putty pointed, but we can, of course, provide bevelled glazing beads if required. Sash horns can be shaped to your design if required.

Our standard ironmongery includes brass axle pulleys and quadrant fastener, but it is entireley your choice. All screws and nails used in the manufacture are coated for durability.
