VENTILATION THROUGH RIDGE CAP

Structure characteristicts:

  • PITCHED ROOF WITH BREATHABLE UNDERLAY

  • THERMAL INSULATION BETWEEN AND OWER TIMBER RAFTERS

  • WITH PLASTERBOARDS

  • INTERNAL FINISH

Structure advantages:

  • VAPOUR OPEN

  • AIRTIGHT

  • SOUND RESISTANCE

  • SPEED OF INSTALLATION

  • TIMBER PARTS INVISIBLE FROM INTERIOR

  • REPLACEMENT OF EXISTING INSULATION WITOUT INTERVENTION TO INTERIOR
