  • Any moisture build up between the outer metal roof covering and the Permo Sec will be channelled safely to the eaves due to the nature of the 8mm mesh outer layer.

  • With an accoustic value of 8db, Permo Sec will help to reduce the transmission of external structure borne sounds e.g. rain hammer.

  • Will cover any irregularities within the roof deck, that could de-form the metal roof covering.
