Pool covers are used in order to achieve perfect thermal insulation through hollow sections. Evaporation and heat emission are drastically reduced. This will extend the bathing season both in spring and in fall. Clear benefits of a pool cover are reduced water pollution and chemical consumption and almost no algae growth. For economic reasons, a pool cover is required when a pool heater is used. We offer pool covers supplied by Bieri Alpha Covers, a leading Swiss manufacturer now based in Germany. Ettlingen has been the new site since 2014.
