Wooden Sash Windows

Traditional wooden sash windows, our installers can offer solid timber windows, using oak, hard woods or softwood. Being a natural material, solid timber can twist and move over time. Warped timber destroys any weather performance and sash windows rely upon precision manufacturing and touching brush seals. To avoid any such problems we use high performance laminated or engineered timber. This construction makes a solid, timber section, free from knots with incredible strength properties.

You can have the choice of two Bygone ranges; the traditional timber sash window hung on weights and pulleys or hardwood sash windows hung on spiral metal balances that also allow an easy cleaning option.
