Harvia uses energy-efficient PIR insulation

At Harvia we believe the best sauna is also an energy-efficient sauna. We carefully select the materials used in our saunas for this purpose. We are continuously working on developing and researching new materials to ensure our products give the best experience for their users. The PIR insulation we use in many of our saunas is twice as insulating as rock wool. A well-insulated sauna heats up quickly and effectively using the energy from the sauna heater.
