Naturheld
Natural wood-fibre insulation
Naturheld, based in Grafenwöhr in Bavaria, develops and produces wood-fibre insulation systems for modern timber construction, solid buildings and energy-efficient refurbishment. The company combines renewable raw materials with practical solutions for roofs, walls, façades and interiors.
A broad insulation system
Its product range includes rigid wood-fibre boards for various applications, flexible insulation batts for spaces between rafters and studs, and blown-in wood-fibre insulation for filling cavities, including areas that can be difficult to reach with conventional products.
Thermal and acoustic comfort
Wood-fibre materials offer heat storage and insulating properties that can help protect against winter heat loss and summer overheating, while also contributing to acoustic comfort. As with any insulation, performance depends on the specified product and the complete construction build-up.
Renewable raw materials
Naturheld’s sustainability approach includes the use of wood-industry residual material from regional sources. Timber-based products also store biogenic carbon during their service life; a full environmental assessment considers production and end-of-life impacts.
Eco-Island and practical learning
Naturheld supported the 2026 building camp with insulation expertise and materials, offering a practical opportunity to discuss how natural insulation integrates into timber construction.
