Sliding Sash - spring Sash Windows

The sliding sash on our spring sash windows is balanced with a spring system as opposed to weights. These ‘vertical sliders’ are more suitable for modern buildings that have the same brickwork dimensions both inside and outside, as these windows do not have a hollow box frame, but a solid frame.
