Description
Sash window weights are used to counterbalance the weight of a sash in a box sash window. With the correct weights fitted, the sashes can be positioned at any opening height without them slipping down or rising. Opening and closing will be simple and effortless. Original sash windows contained single panes of glass and the sashes were relatively light. Modern sashes are double or triple glazed and as a consequence, much heavier. As older windows are upgraded, the sash window weights require replacing. Heavier weights are needed to compensate for the increase in glazing weight. Back in 1985, Mighton Products recognised this and developed the Steel Sash weight. They are now a standard in the sash window manufacturing industry. Steel weights are denser than their traditional cast iron counterparts, so you can squeeze more weight into a sash window box. Allowing you to compensate for heavier sashes. A simple solution and easy to fit.
We can calculate which steel weights you will need if you enter your sash sizes & glass configuration into our Sash Weights Calculator.
Steel weights offer great value and cost significantly less than traditional lead sash weights. We stock them in a whole range of sizes for next day delivery.
Whilst steel sash weights will fit the majority of sash windows*, unlike lead, steel weights are unable to be cut down to size.
To avoid errors, after calculation, please check the steel weight section size will fit your window’s sash box or call us for advice on 01223 497097.
More information on fitting sash fitting weights is available in our Knowledge Hub.
*Work with over 95% of all sash box sizes for both retro-fit and new build.
**IMPORTANT: Owing to manufacturing processes our steel weights can vary by up to +/- 5% in both length, section size and weight.
