Roof Weather Resistive Barrier

connect variant with self-adhesive strips

Advantages

  • Excellent UV resistance
  • Highly vapour-permeable
  • Long-term durability and high strength
  • Weathertight & airtight weather-resistive barrier (WRB)
  • Helps protect a building from condensation
  • Fire Retardant (FI <5 as per AS/NZS1530.2)
  • Can be installed on Walls and Roofs
  • Can be installed vertically down to 3 degrees when supported by corrosion resistant material

Areas of application

SOLITEX MENTO® 3000 provides superior weather and condensation protection for your roof under all weather conditions . With type R4 classification (NZS 2295), it is suitable to be used in self-supported applications up to and including extra high wind zones. SOLITEX MENTO® 3000 protects your roof and building envelope from the elements during construction while allowing any internal moisture to escape through the vapour permeable, non-porous TEEE layer. For skillion roofs, fibrous insulation can be installed hard up to the underside of the membrane as it is non-porous. Can be used directly under metal roofing as per E2/AS1, or with a ventilated cavity as per pro clima construction details (or ASV system).

For Application guidance when using SOLITEX MENTO® 3000 as a wall underlay, refer to the SOLITEX EXTASANA Wall Application Guides.
