Thermakraft Ausnet Wire Mesh

Ausnet is a galvanised steel wire mesh for used to support roof underlays, foils and glass wool insulation. Ausnet is easy to install and can be used on timber and steel framing. The product consists of a pattern of woven flat hexagonal shaped wires.

Key Features
  • For use on timber and steel framing to support roof underlays, foils and insulation
  • BRANZ Appraised — Appraisal No. 1029 (2018)
Scope of Use

General Application:

AUSNET must be run continuously across roof rafters, top truss chords or across purlins and be fixed in place. Roofing underlay that requires an intentional sag as per the building design to facilitate water drainage must have the wire mesh installed with a sag to accommodate the underlay. Where roofing underlay does not require any sag, the wire mesh must be pulled taut.

Application Direction:

The installation direction of the AUSNET mesh must be the same as the underlay, foil or insulation's installation direction. For example, if the synthetic underlay is installed from the top point of the roof to the lowest point (vertically) then the AUSNET mesh will need to follow the same direction

Limitations on Use

AUSNET is not a Safety Mesh. It must not be used at any time to replace the function of a safety mesh as it will not provide safety against falls during roof installation.
