Sensitive to the architecture and period of your building
Often referred to as horizontal sash windows, our timber Yorkshire sash window design couples a smooth gliding mechanism with advanced draught proofing using our patented seal system to provide unrivalled performance.

We also offer narrow sash rails for historic properties that need to meet strict conservation and listed property planning requirements.
We have carefully selected an elegant and traditional sash furniture collection which provides high levels of security.
For maximum security, toughened glass can be specified to meet the demands of Part Q.
From windmills to traditional stone cottages, the Yorkshire sash is a charming addition to the George Barnsdale range.
