What makes Naturheld products special?
- Local and circular: The products are made exclusively from sawmill by-products sourced from regional, sustainable forestry.
- 3-in-1 protection: They provide outstanding protection against both winter cold and summer heat, while also offering excellent acoustic insulation.
- Positive CO₂ balance: During its growth, the wood wool insulation absorbs carbon dioxide and permanently stores it within the building structure, directly reducing the ecological footprint.
