A traditional range of ironmongery with choice of external run through horns

Our exceptional timber box sash windows offer sublime aesthetics, beautiful furniture and a full range of glass decorations. These windows just fall into place whether it be a traditional or modern building.

We offer three timber options: Sapele Hardwood, Oak and the engineered timber Accoya. Whilst both hardwood options are extremely durable, Accoya has a durability and stability greater than that of Class 1 hardwoods such as Teak providing the longest lasting durability available.

As with all timber box sash windows, security comes by the central fitch catch locks and then for additional security you have the option of full pop out security stops if required.

The beautiful range of ironmongery and glazing also allows you the customer to then add your final touch to the finished product. The full range of glazing including decoration such as lead work or slim bar work then allows you to really tailor the product to your requirements.

Along with being beautifully made and to the highest of specification standards, the added benefit of timber is the bespoke nature in design. The standard colour range offers a great range of stains and painted finishes but also the offer of any colour you want allows you the customer to really put your stamp on that final finish. The windows all come fully finished from the factory receiving a three layered micro porous paint treatment.
