spring sash windows
DESIGNED FOR NEW BUILD PROPERTIES
The Scotts New Build Range is highest performing and certified to enable its selection in a new build property where the highest levels of thermal performance and security are mandatory.
Scotts New Build spring sash windows are market leading and retain the beauty of a traditional sash albeit with a 24mm double glass unit and an applied glazing bar system. It is comprehensively weather sealed and certified to BS6375.
HOW IT WORKS
Spring Sash Windows are made using a head, cill and two jambs to create a frame and the frame is divided into two ‘runs’ – the inner and the outer. The runs are separated by the ‘parting bead’ that is positioned centrally on the inside face of the frame and are stopped on the inside by the ‘staff bead’ and on the outside by the ‘external liner’.
The ‘top sash’ slides up and down in the ‘outer run’ and the ‘bottom sash’ slides up and down in the ‘inner run’. The sashes are counterbalanced by ‘spring balances’ that are invisibly situated on each side of the window and are attached to the sashes and the frame.
The resulting window allows either sash to be opened individually or simultaneously in exactly the same way as the traditional cord and weight sash window. Sashes can be locked shut by engaging the sash stops in the closed position or locked in an open position to allow some secure ventilation. For full security the sash stop should be engaged in the closed position and both sash catches securely engaged and locked using the key provided.
