What is the purpose of a roller shutter cover?

A roller shutter cover is a sensible investment for your pool in many ways: Since 80 percent of the thermal energy is lost through the water surface, a roller shutter cover ensures effective insulation of the pool. Thanks to integrated solar elements, it can heat the pool water using  solar energy – and at no cost. In addition, the roller shutter cover fulfills important safety and protection functions: Since the cover lowers itself at most to the edge of the roller shutter when under load, you can be sure that children or dogs will at most get wet feet if they take a misstep. Leaves and dirt enter the pool far less. Deposited dirt is vacuumed off in the roller shutter shaft, keeping the pool clean. Not to forget: of course, the cover also protects against mechanical damage to the pool surface.
