Calculation of opening / closure force
Using the formulas on this page, approximate calculations can be made for the force required to open or close the
window considering all the factors that determine the calculation.
Symbols used for the calculation:
F (Kg) = Force for opening or closing
P (Kg) = Weight of the window (mobile sash only)
C (cm) = Opening stroke (actuator stroke)
H (cm) = Height of the mobile sash
F
For horizontal light domes or skylights
F = 0,54 x P
(Eventual weight of snow or wind on the cupola should be
calculated separately).
