Baufritz’s HOIZ insulation awarded C2C Certified® GOLD

We are proud to announce that our HOIZ organic insulation has been successfully certified under the Cradle to Cradle Certified® programme in the Material Health category. This independent certification from the Cradle to Cradle Products Innovation Institute verifies that HOIZ contains no substances that are harmful to human health and supports a healthier living environment. This fits perfectly with Baufritz’s long-standing commitment to sustainable, toxin-free homes.

HOIZ is made at our factory in Erkheim, Germany, using wood shavings sourced from nearby sawmills as a by-product of softwood processing. The wood shavings are treated with natural soda to provide flame, fungal and pest protection without resorting to chemicals. HOIZ is installed in all Baufritz roofs, walls and ceilings as thermal and sound insulation.

As part of our continued focus on circular design, we are also working to gain certification for HOIZ in another, equally important category, Circularity. We expect to complete the process in spring 2026. This certification will be further recognition of our efforts to ensure that HOIZ can be reused or fully recycled at the end of its life.

These achievements reflect Baufritz’s holistic approach to using healthy, eco-friendly building materials and underlines HOIZ’s leading role as an organic insulation product in the UK market.
