Wednesday, 7 August 2019
By John Kitchen
In proprietary tests undertaken by two reputable international cladding manufacturers and their respective New Zealand Distributors, GIB Weatherline® was included in combination with claddings to pass two separate NFPA285 full scale Façade fire tests.
MBIE have recently announced the “Building Performance Guide: Fire Performance of External Wall Cladding Systems” which summarises available pathways for NZ Building Code Clause C3 External spread of fire and includes a risk matrix for fire testing protocols.
In buildings deemed Low Risk applications, GIB Weatherline® Rigid Air Barrier Systems meet or exceed the requirements of NZBC Performance Clause C3.5.
For Medium Risk applications, to comply with MBIE Protocol P1, GIB Weatherline® has been tested in accordance with ISO 5660-1 meets the requirements of C/AS2 to C/AS7 paragraph 5.8 and can be used as a component in medium risk applications provided other cladding components also comply with MBIE Protocol P1 guidelines.
However, to meet High Risk Applications MBIE protocol P3, 13mm GIB Weatherline® Rigid Air Barrier was tested on timber framing with internal insulation in two separate NFPA 285 full scale façade tests in combination with both Alucabond and Reynodual claddings systems.
