Sliding Sash Windows
Classic vertical sliding sash windows that combine traditional elegance with modern energy efficiency and security.
Classic Sliding Sash Windows
Sliding sash windows are a quintessentially British window style, found on properties from the Georgian era right through to the present day. Our UPVC sliding sash windows faithfully replicate the charm of traditional timber sash windows whilst delivering all the benefits of modern materials.
Featuring a smooth spring-balance mechanism, authentic run-through sash horns, and deep bottom rails, our sliding sash windows are virtually indistinguishable from timber — but they'll never rot, warp, or need painting.
Both sashes tilt inward for easy cleaning from inside your home, and advanced multi-point locking provides excellent security without compromising the traditional aesthetic.
