摘要

The natural fibers as chopped insulating material are used in buildings and have a relative moisture of between 12 and 20 per cent, and preferably 14 per cent, and the length of the fiber component parts come to between 0.1mm and 50mm. The diameter of the fiber component parts comes to between 01.mm and 30mm. The natural fibers used as insulating material are mixed with other natural fibers which could be recycled material and especially cellulose fibers as with the utilizing of old paper.
