Namely, swimming pool covers are ideal for preserving the temperature of your swimming pool, especially if you are aware that the largest portion of energy escapes through evaporation. The protective cover prevents the water to change its aggregate states by physically limiting it, while at the same time the energy exchange between the interior and the exterior of the pool is reduced. Surely, the covers are also useful for above-ground pools, whether they have any other type of insulation or not.
