Balance Calculator
Please complete the form below in as much detail as possible and we will calculate the required sash balances.
It is always more accurate to weigh your sashes and input the weights in lbs below. However, if you do not know your sash weights, leave the boxes blank and we will calculate the weights for you.
Please note:
- The Value of A must be less than B + C - 25 MM
- Our Calculators are designed to calculate balances for Softwood windows only. To have us calculate your balances requirement for any other window (including titling and hardwood windows) please call our Sales team on 01223 497097
