CODE: SBC
|
The Natac range of spiral sash balances are designed for use in both conventional vertical sliding windows and vertical sliding windows with a tilt-in-facility, together with serving hatches and counter screens.
Natac spiral balances are in use throughout the world in PVC-U, aluminum and timber windows. They are designed to counter balance a sash, holding it in any position. Whilst balances are not designed as a mechanical opening device, they do give a degree of assistance when operating the window.
Principally specified for timber windows or secondary glazing screens, Spirex balances are suitable for sash weights between 1kg and 13.5kg and sash heights of 200mm to 1200mm. Spirex balances are sprung in a 14mm diameter aluminum tube and offer approximately a 25% mechanical advantage.
