Timber sash windows

Upgrade the security and thermal efficiency of your home without sacrificing aesthetics with an Inspire timber sash window.

Wooden sash windows maintain the classic charm of your property, while offering all the high performance benefits of slimline double glazing and precision manufactured frames. With low-level maintenance, our sash windows can last upwards of 50 years.

Inspire sash windows can be manufactured using a weights and pulleys system which closely replicates those used in original sash windows, or with spiral balances more suited to a modern property. Every window is made to measure and can replace modern double glazing or traditional box sashes, with period features such as a deep bottom rail, Georgian bars and run-through sash horns.
