What are uPVC and aluminium sliding sash windows?
Sliding sash windows were a common sight in Georgian and Victorian homes and consist of a movable panel which allows you to easily control the ventilation in your home. Our sliding sash windows allow you to retain the original character of your home while improving its performance. They offer a simple operation with the use of tensioned balances. Either sash can also be tilted inwards to allow for easier cleaning. Spring balances are concealed within the framework for easy adjustment and eliminating the need for cords. With traditional features such as an oval-shaped frame and classic sash horns, the authenticity is retained, and they can be approved for use in conservation areas.
