the organic insulating materials to the cellulose fiber is currently the most important. This is certainly attributable to the fact that cellulose insulation products are fully competitive with conventional insulation materials like mineral wool or foam insulation. In addition, the special suitability of wood frame construction.
production
cellulose flakes are made from recycled paper, which typically originates from daily newspapers. The paper is in several steps mechanically crushed and frayed. This changes the cellulose their structure is a snippet from a paper three-dimensional cellulose flake that offers through their networking with each other a high level of security setting. After the addition of boron salts (15%) is cellulose insulation in all the fire class B2 - reached normal flammability. Some new products, even the fire class B1 - entflammber. This addition also protects against mold infestation. Some manufacturers now offer free and borate cellulose flakes. As fire protection and fungicide agents are here then ammonium salts or aluminum salts. Trade names for the cellulose insulation flakes include Isoflock and Climacell.
properties
cellulose flakes have a thermal conductivity of 0.040 to 0.045 W / m² K is a very good insulation and provide good sound insulation properties. It contains no chemicals exhaling, is vapor permeable and has a moisture-regulating.
application
cellulose flakes can be used in many ways. The following processing procedures are common in practice:
- lot heaping
- Open-blowing
- Filling cavity blowing in air-tight cavities
- Feuchtsprühverfahren
The trade name for cellulose flakes include Climacell or Isflock
