Secure timber sliding sash windows with a U-value of 1.2 W/m²K in double glazed.
Suitable for most applications.
Particularly suitable for unlisted properties where replacement windows are required, or for new build projects which need to achieve all of the relevant building regulations but the customer does not require Passiv-Haus level performance.
Chatsworth timber sliding sash windows combine low maintenance, longevity, and excellent draught-proofing, with a classic appearance. For additional authenticity, the range is available with either spiral balances or a traditional weights and pulleys system.
They provide architects and specifiers with a reliable and visually appealing solution for unlisted properties requiring replacement windows or new build projects adhering to building regulations. With excellent value for money and wide-ranging suitability, these windows are a versatile choice for most properties.
