Our unique range of timber windows feature stepped sashes for improved performance yet retains traditional sight lines. We supply them fully glazed with 24mm Low E insulating glass units.

Ventilation is achieved through a concealed ventilator (s) in the head section. All windows have extended horns on the top sash and flush-to-frame sills as standard. With large windows we may supply the sashes separately – to make frame fixing and handling easier, and to reduce the risk of damage.

We supply all vertical sliding sash windows with concealed flush-fitting ventilators as standard in white or brown. Windows less than 488mm wide are not fitted with ventilators. 8000mm2 geometric are supplied fitted on windows 860mm and wider, 4000m2 or below that size down to 488mm wide.

A “no vent” option is also available please ring our sales team on 01205 363999
