What is a Sash Window?

A sash window features one or more glazed panels that slide vertically within the frame. A staple of British architecture, this classic design is known for its balanced proportions and timeless appeal. Our Legacy sliding sash windows retain traditional styling while incorporating modern UPVC performance for improved insulation, security, and longevity.

Why Choose Our UPVC Sliding Sash Windows?

Energy Efficiency

Built with multi-chambered frames and 24mm argon gas-filled double glazing, our sash windows achieve a Window Energy Rating of A and a U-value of 1.4W/m²K as standard. Warm edge spacer bars further reduce heat loss, helping prevent draughts and keep your home warm and efficient all year round. A thick 128mm front-to-back profile adds strength, while colour-matched woolpile seals protect against weather and debris.
