FLAX INSULATION PROPERTIES

Manufactured in thermobonding airlaid process for three-dimensional stability.
Standard thicknesses are: 50, 75, 100, 125, 150 mm.
Standard widths: 565mm (thicknesses 50/75/100/125/150mm)
and 865/870mm (thicknesses 100/125/150mm).

ENVIRONMENTAL AND HUMAN HEALTH ADVANTAGES

• fibres form no possible health risk
• biodegradable and disposable
• low load on the environment
  
  • no pollution of air and water,
  • no emission of harmful chemicals like formaldehydes,
    isocyanates, organohalogens, (H)CFCs, etc.
  • total process: good energy balance
• the annually regrowing crop is an inexhaustible resource that does not contribute to global warming.
  even better; during its growth it converts the greenhouse gas carbon dioxide (CO₂) into oxygen (O₂).

APPLICATION ADVANTAGES

• roll-form reduces the amount of seams (points of heat loss)
  and speeds up installation process (one piece from ceiling to floor)
• plate form can be easier to handle in places difficult to reach
• no need to wear various inconvenient personal protection means
  to avoid irritation of the eyes, skin and lungs
• areas need not be forced ventilated during installation.

PHYSICAL ADVANTAGES

• very good thermal and acoustical insulating properties
• flax insulation offers excellent temperature buffering characteristics,
  resulting in gradual temperature changes for a comfortable indoor living climate
• very good “breathing” properties due to its hollow-fibre composition
  which can have beneficial effects on surrounding constructions as well.
