Water-Permeable Underfloor Insulation

Kingspan AIR-CELL Permifloor is an underfloor insulation innovation designed specifically for suspended framed floor applications delivering a 2-in-1 insulation and moisture management solution.

Manufactured with a patented closed-cell, cross-linked foam structure sandwiched by highly reflective foil surfaces and perforated with tiny, evenly-spaced holes, these perforations allow water and vapour to permeate through preventing moisture that can often collect under flooring when using conventional underfloor insulation systems.

500 mm wide pre-cut version is also available for a perfect fit between joists (Kingspan AIR-CELL Permifloor 500).

  • Australian made
  • 2-in-1 insulation and moisture management solution
  • Rodent and insect resistant

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 National Construction Code, calculated in accordance with AS/NZS 4859.2 2018 & 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.
