Counterbalance Systems
Following the market uptake of uPVC sash windows, modern counterbalance systems were introduced to replace cords and weights, including spring balances and constant force coil mechanisms. These counterbalance systems enable the sashes to move smoothly and stay in position. Specific systems appear more appropriate for windows of particular sizes, which has led us to implement the following changes:
Windows with sashes up to 850mm in height will have constant force, quick release, and standard sash stops as they do now.
Windows with sashes between 851mm and 1150mm in height will have constant force, no quick release, and extended sash stops.
Windows with sashes 1151mm and over in height will have spring balances, quick release, and standard sash stops as they do now.
Please note that windows specified with PAS 24 security must have spiral balances and a fee may be applicable.
Extended Sash Stops
As listed above (point 2), on windows with sashes between 851mm and 1150mm we will be using extended sash stops, which will reduce the sash openings slightly to ensure the full rated load of the coil mechanisms isn’t surpassed.
For reference, please note the picture of the extended sash stop fitted on a 2400mm tall sash window.
