Isovrac

ISOVRAC blow-in wood fiber is a multi-use insulant that can easily be installed in your building. The wood fiber has an insulation coefficient high enough to withstand very cold and extremely hot temperatures. In addition to its insulating qualities, ISOVRAC wood fiber has a high fire-resistance rating (Euroclass B) and resistance to mold (Class 0).

Areas of application

Insulation for finished and unfinished attics

Interior insulation, furring tile and glazing

Optimal interior insulation

  • Insulation for usable and unused roof space
  • Pressure drying of walls

Recommendations

Store and install in dry conditions

Work space ventilation is recommended

Must not come into contact with fire-tubes or sources of intense heat

Wood fiber is spread evenly throughout the roof space that is being insulated using a blowing machine. The different types of blowing machines are equipped with flexible hoses, allowing the insulation to be blown in over all surfaces of the roof space. It can be used with all types of machines
