Air-Cell Insulbreak Wedge

3-in-1 Insulation, Thermal Break, and Vapour Barrier

Kingspan AIR-CELL Insulbreak is a 3-in-1 insulation, vapour barrier and thermal break solution for steel-framed construction.

In steel-framed buildings, Kingspan AIR-CELL Insulbreak delivers the R0.20 thermal break required for NCC BCA compliance*, reducing thermal bridging and conductivity between building elements. It is also commonly used in non-steel framed applications such as timber framed roofs.

Assumption and Key

The R-values shown are Total R-values for the building element as required by the Energy Provisions of the Building Code of Australia. Kingspan AIR-CELL products are manufactured, tested and packaged in conformance with AS/NZS 4859.1.

The contribution of the product Total R-values depends on installation and environmental conditions. The R-value will be reduced in the event of the accumulation of dust on the upward facing surfaces and in those cavities that are ventilated.

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 50 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.
