The 12mm Spa Heat Retention Cover has been specifically designed for use on spas (hot tubs) and hydrotherapy pools due to their high temperatures, increased chemical levels and significant water evaporation.

This lightweight 12mm foam blanket (Weighs: 0.49kg per sq.m) has a laminated top and bottom with an embossed clear protective layer. It is double the thickness of most swimming pool covers in order to reduce the water evaporation in the spa by up to 90%. Water evaporation accounts for 70% of heat loss in spas.

This premium material can withstand water temperatures up to 39 degrees C and with this carries a 1 year guarantee.

This cover is not suitable for use with swimming pool reel / roller systems and is also not hemmed. Covers can easily be removed from the spa / hydrotherapy pool by hand.
