This high quality equipment is not to be confused with the infamous ‘spiral balance’. Although it may at first look very similar it works on very different mechanical principles.
The Sashpro Balance has been around for a while now and we’ve used it exclusively in our timber box sash windows when new double glazed sashes outweigh lead or iron counter-balance weights. Due to the Sashpro Balance dimensions box sash window frames can now be installed into window apertures, dormer window frames and modern buildings in much the same way as casement windows, with no exposed timber linings. Email us for a data test sheet. You’ll be surprised at how this solution provides for an efficient alternative from toxic lead.
