Weights Calculator
Please complete the form below in as much detail as possible and we will calculate the required sash weights.
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 weights for Softwood windows only. To have us calculate your weights requirement for any other window (including hardwood windows) please call our Sales team on 01223 497097
