Timber Box Sash Windows
Westbury’s timber sash windows offer unique style, period authenticity and have traditional sight lines
Our Box Sash Windows use pulleys, cords and weights to counterbalance the top and bottom sashes. The weights are housed in a ‘box’ created by liners extending the frame on each side internally and externally.
Offering the best of tradition and modern technology, our timber Box Sash Windows retain authentic heritage styling with the latest technology for improved security, thermal and acoustic performance.
Distinctive design features include decorative sash horns, a concealed trickle vent detail, deep moulded lamb’s tongue profiles with 21mm glazing bars and internally moulded staff beads.
Operating with a finger-touch push, our timber sash windows are an elegant addition to any new build or refurbishment project. Westbury’s timber sash windows are available in traditional box cords & weights or solid frame with pre-tensioned heavy-duty balances.
All of our Sash Windows incorporate a heritage design, suitable for conservation areas. They are 68mm deep and can therefore incorporate a thicker and wider choice of energy-efficient and sound-reducing glass, from our 16mm Classique to our triple glazed options.
