Sashless double hung windows are a popular choice to save space whilst creating a clean, modern aesthetic. They provide controlled and positive ventilation.
They are user friendly, with spring balances for ease of opening and closing. They allow for ventilation through the top or bottom of the window.
The window comes with the choice of the traditional cam lock, or they are also key lockable.
The double hung aluminium window is also available as a single hung window system with one sash being a fixed window.
