Junction Details

Application

This James Hardie junction booklet provides the most common junction details between different James Hardie cladding products and James Hardie and other cladding products. These junction details have been developed based on the current knowledge and considering the current construction practices being followed in the industry.

These details have been carefully developed to minimise the moisture ingress through these junctions. The performance of these junctions rely on the workmanship of persons installing the products.

While every care has been taken in detailing these junctions, still the designers, specifiers or installers should ensure that the selected details are suitable for the project they are working on. When using a James Hardie cladding product, refer to the relevant James Hardie product literature for further information regarding installation, product sizes, accessories and warranty.

Fixings, flashings and other components used must meet the durability requirements of 'Clause B2' of NZBC. The construction method to be selected should be as per the relevant product literature.

Note: The junction flashings shown in the details are available through the merchants.
