The timber sash window is a classic window design and features heavily on some of the most distinguished buildings in the UK. Our hardwood sash windows offer that same timeless elegancy with modern performance.
By crafting our windows from the highest quality timber, we can ensure a highly durable finish, perfect for the harsh and wet British climate. Each timber sash window is finished from our range of lacquers and paints to suit the project requirements.
Our hardwood timber frames are highly insulating and, when paired with a double or triple glazed unit these timber frames offer excellent thermal insulation.
Our timber sash windows are available to be designed and manufactured using the following timber options:
Exotic hardwood species that boast impressive resistance against hard weather, shrinkage, bending and swelling. The surface of the wood is exceptionally elegant and is often chosen for its beauty, it can look outstanding with just a transparent paint.
