Pool Lounge is a walkable, fully resilient and automated cover for in-ground pools, hot tubs and swim spas, able to withstand 320 kg/m² of pressure. Heated rails allow for a smooth opening, even at freezing temperatures. Thanks to its dirt preventive properties, Pool Lounge reduces the use of water cleaning agents, and, furthermore, brings down water heating costs to a considerable degree and minimises the evaporation of water. The innovative insulation is based on a nanotechnology coating.
