The Naturplus® independent expert panel rigorously evaluated the environmental, health and technical properties of THERMOFLOC insulation prior to certification. Only sustainable products with a high renewable raw material content can be certified since it has been shown that these materials have a positive effect on the indoor climate. The strict limits on harmful gas emissions mean using THERMOFLOC helps prevent the emission of harmful gas from insulation within the building fabric as well as minimising the consumption of fossil energy sources. What’s more, these strict limits ensure that no adverse effects on health come from THERMOFLOC. The Natureplus® mark also backs up the durability and long service life of the insulation.
