The component is discreetly set and hidden within the window frame, making this one of the finest, secure and energy efficient methods to combine with your sash window, read more information on our products here.

The “block & tackle” Balance Systems Innovations company became aware of the need to produce additional products that complement the balances. In so doing, we provided the window manufacturer with a full range. We are a one source supplier to the fenestration industry. Contact us to discuss any requirements.

The company’s objective has been to develop and design a cost effective way of supporting your sash windows.

We have a range of products to service the fenestration industry within Europe with quality hardware products for vertically sliding sash windows.

 The prime product since our formation, has been the “block & tackle” sash balance, a vital component to manufacturers of vertically sliding sash windows. 

The block and tackle principle of pulleys and ropes is a tried and tested method of moving and supporting weights.

When incorporated within a channel section and using modern cords giving a 5 to 1 mechanical ratio and supported by specially treated steel springs, as a balance, it now becomes a component suitable for the application to modern windows and an alternative to a spiral balance.

The window manufacturer obtained subsequent performance advantages of a pre-tensioned alternative product.

“Balance Systems Innovation are proud to be supplying the balances for the sash windows of Quadrant House on Regent Street.”
