Schüttdämmstoffe

Schüttdämmstoffe, also known as loose-fill insulation or blown-in insulation, are granular or fibrous materials used for thermal insulation in buildings. They are typically installed by being poured or blown into cavities, attics, or wall spaces. The loose nature of these materials allows them to fill irregular shapes and small gaps effectively, creating a continuous insulating layer. Common materials used as schüttdämmstoffe include mineral wool (rock wool or glass wool), cellulose (recycled paper), perlite, vermiculite, and cork. Each material has distinct properties regarding thermal conductivity, fire resistance, moisture permeability, and environmental impact. The installation process often involves specialized blowing machines that distribute the insulation evenly within the building structure. This method is particularly advantageous for insulating hard-to-reach areas and existing buildings where access is limited. The effectiveness of schüttdämmstoffe depends on proper installation to avoid settling and to ensure a consistent density throughout the insulated area. They contribute to energy efficiency by reducing heat loss in winter and heat gain in summer, thereby lowering heating and cooling costs. Furthermore, some schüttdämmstoffe offer acoustic insulation benefits.
