Solar foil is the most common way of covering the water surface. It protects the pool from getting dirt inside it. Thanks to numerous air bubbles, it significantly reduces the evaporation of water and therefore it reduces the expenses associated with heating. The solar foil is a rigid foil 400 microns thick, it is resistant to weather conditions (it does not fade or crumble). The shape of the foil can be adjusted to a specific basin by easily cutting it. Thanks to aluminium retractor, to which the foil is attached, it is to easier to unfold it on the surface of the pool. The rolling machine located at the edge of the pool is available in a fixed or mobile version.
