AIR-CELL Permicav XV

Vapour-permeable Insulation for Walls with Cavities

Australian-made Kingspan AIR-CELL Permicav XVTM is the next generation of vapour-permeable insulation. This insulation is specifically designed to reduce the risk of condensation in walls with cavities. The micro perforations allow water vapour to permeate through while keeping moisture out and maintaining thermal resistance.

Kingspan AIR-CELL Permicav XVTM is manufactured with a patented perforated closed-cell core sandwiched by highly reflective foil facings.

The Kingspan AIR-CELL Permicav XVTM is suitable to provide a vapour-permeable insulation solution on low rise structures. For consideration in high-rise buildings, please contact Kingspan Insulation’s Technical Services Team.

  • Australian made
  • 3-in-1 insulation, vapour-permeable membrane and radiant barrier
  • Wall cavities remain unfilled and accessible for services
  • Water-resistant and unaffected by moisture

Assumption and Key

NCC 2019 prescribes different methods to determine Total R-value Calculations for Volume 1 and Volume 2.

The R-values shown are Total R-values for the building element as required by the Energy Provisions of the NCC Volume 2, calculated in accordance with AS/NZS 4859.2 2018 and NZS 4214, as required.

General Requirements

  1. Fit Kingspan AIR-CELL neatly around doors, windows, and any penetrations, and tape if necessary to prevent air leakage.
  2. When taping a plastic squeegee or blade must be used to apply appropriate pressure to the tape. Surfaces must be dry and free from dust, oil or grease prior to taping (please refer to brochure ‘Kingspan Insulation Tape’ for further information).
  3. Leave minimum 100 mm clearance around heat producing flues or light fittings (refer to light fitting manufacturer).

The instructions in this document are guidelines only and should be interpreted with consideration for the specific building design. The installation of Kingspan AIR-CELL should be in conformance with the applicable clauses from AS 3999 and AS/NZS 4200.2 unless otherwise specified.

Kingspan AIR-CELL can be damaged by intense heat above 105° C and contact with sparks and flame from blow torches, welders, cutting tools, etc. must be avoided.

The installer must make due provision for safety when installing Kingspan AIR-CELL in any application.

Condensation

As thermal performance requirements for the building fabric continue to rise, condensation is becoming an increasingly important design consideration for healthy buildings. Ineffective management of
moisture and vapours can potentially lead to indoor health issues and structural defects which require expensive remedial works.

Interstitial condensation (condensation that occurs within the cavities of the building fabric) can go unnoticed for long periods of time and when persistent it promotes the growth of mould, rot in timber, and corrosion of metal framing and fixings. This interstitial condensation can be effectively mitigated by carefully selecting an appropriate building membrane with a suitable water vapour permeance, allowing moisture to harmlessly pass through the structure.
