Description
Westbury timber wood sash windows slide open with ease and smooth movement, offering exceptional security, thermal and acoustic performance. The spring balanced sash window is a contemporary alternative to the classic box sash window, using a spring-loaded mechanism instead of the pulleys, cords and weights found in a traditional box sash window. They are often used in new builds where a flush reveal has been detailed by the architect. Legacy sliding sash windows have thinner frames, sash and glass sections and are suitable for replacing draughty single glazed windows. They give a modern performance without losing the traditional heritage sash window aesthetics.
Features and benefits:
- Distinctive style, period authenticity and have traditional sight lines.
- Contemporary alternative to the classic box sash window.
- Uses spring-loaded mechanism instead of the pulleys, cords and weights found in a traditional box sash window.
- Legacy design incorporates slimmer double glazed units in a thinner sash section for a more traditional appearance.
- These energy-efficient timber windows are made from premium grade, knot-free engineered Accoya and European Redwood. Accoya is a sustainable wood that is laminated to provide excellent stability and a superior finish.
- Treated with a three-coat, spray-applied, microporous paint system prior to delivery.
