System Description

    The system is assembled on the standard MIRA wood cross section.

  • Very good thermal insulation technical properties.
  • In combination with a triple-glazed pane (Ug = 0.7 W/m2K) and a 68 mm or 78 mm wood
    cross section (fir frame material) that only requires addition of an insulating core in the
    frame, the further development of the MIRA therm 08 is passive house certified.
  • The structure is based on the principle of a rear-ventilated attachment shell secured by
    a PVC bracket.
  • The thermally insulated MIRA therm 08 system profiles may be ordered in production
    lengths (6,000 mm) or as frames with welded or punched corner connections.
