Conservation Sash Windows

“Balancing traditional appearance with modern technical performance and comfort”

Constructed from selected European Redwood from sustainable sources, all sections are double vacuum treated with preservative and primed with white microporous primer unless otherwise specified.

Sash windows in this profile can be 1 pane, 2 pane, 6 pane, 8 pane and so on. Arched and Swept Headed sashes, Venetian Windows, Bay Windows and horizontally sliding “Yorkshire Lights” can all use the same profiles for the sliding sashes.

Sashes can be supplied unglazed but are generally supplied ready glazed, with traditional linseed oil putty bedding and face pointing. 4 mm float glass is used as standard; various glass types are available on request including safety glass, patterned glass and special glass where faithful reproduction of historic detailing is required.

The patented Ventrolla System is built into all new case and sash windows to make them draughtproof beyond the highest requirements of BS6375. They will also open and close easily. Ventrolla “Sash Removal System” is fitted as standard to facilitate long term maintenance.

Brass centre catch and sash lifts are fitted as standard; many decorative and security options are available to order. Sashes are normally hung on cords, pulleys and weights. Spiral balances can be fitted if required.

Windows are made as reproductions of originals and are therefore suitable for Conservation Areas and Listed Buildings. It is advisable to check each specific case with the Planning Authorities. We can provide any samples and drawings that may be required in applying for permission to use our windows.

All joinery and Ventrolla systems are covered by a written 5 year warranty.
