Insulating the hot tub against the coldest environments
Nordic Insulation System is a total insulation system, especially suitable for any outdoor hot tub and in cold environments. It is a 10 mm thermal insulation material made up of 5 layers, in this order:
- Aluminum
- RC9 bubble + low-density polyethylene (with a double layer).
- FONPEX non-cross-linked polyethylene foam (20kg/m3).
- RC9 bubble + low-density polyethylene (with a double layer).
- Aluminum
This material completely covers the entire lateral surface of the hot tub (in addition to the lower insulation, standard in all hot tub ), and creates an air chamber that prevents heat leakage, maximizes energy efficiency and, logically, leads to significant energy savings .

According to our quality department 's tests, to maintain the water at 38ºC with an outside temperature of -15ºC , the Nordic Insulation system guarantees an energy saving of 80% compared to a hot tub without this insulation. Nordic Insulation System considerably improves the energy savings of the EcoSpa service ( 69% saving).
