Cellulose Insulation

The good insulation capacity of cellulose insulation material is guaranteed by:

  • Low air permeability
  • Seamlessness
  • Breathability
  • Cellular structure of wood fibre
  • Good moisture resistance
  • Careful installation

Cellulose wool has excellent moisture resistance, which is demonstrated by its outstanding ability to maintain the insulating capacity when the atmospheric humidity increases. The indoor air humidity is kept at an optimal level and the risk of mould formation is minimised.

With a lambda value of 0.041*, the thermal insulation capacity of Fibratus cellulose wool bears comparison with corresponding products. Its good insulation capacity is based on low thermal conductivity. The cellulose wool features the essential properties of a quality thermal insulation material - it has low air permeability, yet it absorbs air well. The use of Fibratus cellulose wool brings savings in heating costs.

Cellulose wool is also known as cellulose insulation, wood fibre insulation and eco wool.

*Low lambda value; the lower the value, the better.
