Our historical sash is a single glazed window fashioned on the original Georgian box sash, with a box depth of 125mm and delicate lambs tongue glazing bars with external silicone putty.

We regularly provide windows for use in conservation areas and in Listed buildings, where exact replication of the existing design is required.

Our windows are supplied complete with lead weights, factory finished in any RAL paint colour, with a choice of furniture including insurance approved locks as standard. We use 4mm optically perfect glass as standard, however it is also possible to use antique (Polish or Crown glass) to recreate the original distortions that existed in hand made glass.  

For detailed information on our timber specification and environmental policies please see the technical and environmental sections on our website.

Please contact us on 0208 877 8920 or via the email address to discuss your requirements. Our windows are delivered 8 weeks from design sign off.
