However, it is important to remember that if the weight of the garage door is increased by adding glass, additional insulation, or even several coats of paint, the life of the torsion spring may be greatly reduced.
Međutim, važno je zapamtiti da, ako se težina garažnih vrata povećava, dodavanjem stakla, dodatnom izolacijom, ili čak nekoliko slojeva boje, rok trajanja torzijske opruge može biti znatno manji.
