✔ PU foam, high thermal resistance
✔ 30mm thickness, optimised insulation layer
✔ Seamless layer, no thermal bridging
✔ Low-temp stable, consistent performance
✔ Reduced losses, improved energy efficiency
✔ Full coverage, uniform heat retention
Additional thermal insulation is used to ensure the tubs work at low temperatures and to save energy resources. The back of the tub liner is coated with 30 mm of three-
component polyurethane foam, which reduces the thermal conductivity of the walls of the tub to almost zero values. The polyurethane foam is applied to the curved surface
of the bowl without seams or joints. The thickness of the layer is optimal to prevent heat loss.
