Spiral/Slide & Tilt
Sash Windows
Spiral balanced windows feature pre-tensioned spiral balances instead of traditional weights. This method of opening allows the window frame section to be reduced. A solid frame replaces the box housing of weighted windows, which enables the window to be used in tighter and modern reveals. This is also a more cost-effective alternative to weighted and pulley sashes without compromising the aesthetics of the traditional sash window.
