Sliding Box Sash Windows

Our sliding box sash windows are manufactured using traditional methods in hard or softwood, and are made using weights and cord or modern sash balances.  We can also offer our box sashes fitted with single glazed, slimline heritage glass or modern double glazed units.

We comply to European CE marking requirements, and we can calculate accurate U-values for each item using our unique design software. For more information please click on the regulations tab on the top of the page.
