Naturdämmstoffen

Naturdämmstoffe, also known as natural insulation materials, are building materials derived from renewable resources or readily available natural materials. Their primary purpose is to reduce heat transfer in buildings, contributing to energy efficiency and thermal comfort. These materials are often chosen for their perceived environmental benefits compared to conventional synthetic insulation.

Commonly used naturdämmstoffe include cellulose, derived from recycled paper, wood fiber, hemp, flax, sheep's wool, and cork. Each material possesses unique properties regarding thermal conductivity, moisture regulation, sound absorption, and fire resistance. For instance, cellulose is known for its good insulating value and affordability, while wood fiber offers excellent thermal mass and breathability. Hemp and flax are valued for their renewable nature and good moisture-handling capabilities. Sheep's wool is recognized for its ability to absorb and release moisture without significant loss of insulating performance and its natural fire-retardant properties. Cork, a renewable bark product, provides good insulation and is resistant to moisture and pests.

The production of naturdämmstoffe typically involves less energy than that of synthetic insulations, and many are biodegradable at the end of their service life. Their use can contribute to a healthier indoor environment due to their often lower levels of volatile organic compounds (VOCs). However, properties like fire resistance and susceptibility to pests can vary and may require specific treatment or construction methods. Their installation can sometimes differ from conventional materials, requiring specialized techniques to ensure optimal performance and longevity.
