The Pool Lounge is a walkable, fully resilient (320kg/m²) and fully automated coverage fits to in ground pools, hot tubs and swims spas. The high-quality of the Pool Lounge can replace conventional insulation of any pool design as these are normally prone to water vapour and water sanitisers. The heatable rails allow smoothly opening of the coverage even at freezing temperatures. Beside the protection against contamination it reduces maintenance and the consumption of resources. It is a closed-System and therefore the preparatory work can be minimized. The insulation is based on a scientifically developed coating based on nanotechnology, produced in cooperation with Nano GmbH. The coating not only reduces the heating costs of the pool but also makes a considerable contribution to lower water evaporation reducing maintenance and the consumption of resources. The Austrian Research Promotion Agency (FFG) supported its development. The stability and functionality has been inspected and confirmed by the Chair for Chemistry and Polymeric Materials at the University of Leoben. All the components are tested and continually retested in terms of safety and function by the TÜV-Süd.
