As an eco house pioneer we have been using HOIZ, our unique natural insulation for a long time. It was wonderful however to have this commitment to the environment recognized with gold certification in the cradle to cradle award. HOIZ is our completely natural insulation made from wood shavings which are mixed with whey and soda to ensure it is fire retardant and fungus resistant. The gold award for the insulation is just part of the accreditation. Baufritz was awarded the highest standard, Platinum, in the categories of material and material recycling. The award is further proof that Baufritz really are market leaders when it comes to minimizing the environmental impact of a house, from the beginning to end of its life cycle.
