Properties
Cellulose fibres are vapour diffusible, moisture-balancing and sound insulating. The thermal conductivity λ is 0.039–0.045, the water vapour diffusion resistance μ 1–3.

Area ofapplication
Cellulose fibres are ideally suited for insulating cavities between rafters in the roof area, beam ceilings and timber stud walls. Cellulose insulation panels can be installed between rafters, in partition walls and with rear-ventilated facades for external insulation. Cellulose fibre flakes are loosely poured or blown up openly between upholstered timbers of floor constructions or on top floor ceilings. Cellulose is blown under pressure into cavities of roof and ceiling constructions, timber stud walls, etc. using special machines and results in windproof and custom-fit thermal insulation without losses. Even irregular cavities can be insulated seamlessly using the blow-in process. Depending on the type of cavity, different compaction is required so that no empty spaces remain and no settlements occur. There are wet processes for constructions where dry blowing is not possible. 10% pure water is added to the cellulose and this mass is sprayed open. The wall must remain open until it dries out.
