Biodegradable insulating blocks used in building

摘要

The wall element for a building acts as a heat insulator. It may form part of the cladding on the outside of the wall of a new building and may also be added to an old building. The wall element is made of biologically degradable material. The blocks may be made of raw material containing cellulose, bound with a suitable glue or adhesive material. First load-bearing blocks may be used in eg. stud walls and they may carry second facing blocks and even third facing blocks. Different layers of blocks may be held together by distance pieces.
