TABLE NOTES: * For increased heights, stud size may need to be increased. Please refer to James Hardie Fire and Acoustically Rated Walls Application Guide for more information.
# Stud spacing is based on a load bearing capacity of 5 kN/stud. The stud spacing may need to be reduced in accordance to wind pressure installation requirements for the selected external cladding product, please refer to the relevant and respective literature for more information. The loadbearing capacities of the timber-framed walls must be determined in accordance with AS1684 ‘Residential timber-framed construction’ and AS1720.1 ‘Timber structures’
+ Thermal value is based on using a single reflective vapour permeable membrane (e.g. HardieWrap™ weather barrier) with an emissivity of 0.16. The total R-values for common systems are in accordance with AS4859.1:2002 and Amendment 1:2006 Materials for Thermal Insulation of Buildings. Note that the R-value will be reduced in cavities that are ventilated.
^ Additional fastener and design considerations may be required. Refer to James Hardie Structural Bracing Application guide for more information.
~ Stud spacing may be increased to 600mm centres with a reduced loadbearing capacity of 3.4 kN/stud. Please note that if specifying 600mm centres, cutting of HardieFire™ Insulation will be required as sizes have been optimised for 45mm studs at 600mm. It is recommended to install 560mm batts horizontally to minimise cutting. Ensure a 5mm compression throughout and no gaps.
^^ A larger minimum timber stud size may be required, Please refer to framing section under design considerations.
** HardieSmart™ ZeroLot wall system consists of two external boundary walls with minimum offset and construction is commonly staged; therefore, acoustic requirements and above performance values are only measured for each external wall.

SMART. HardieSmart™ ZeroLot wall system is a game-changing smart system. In multi‑occupancy projects, it has the distinct advantage of enabling construction of all dwellings in your development independently. This results in flexibility of building process and improved business cash flow.

SPACE MAXIMISER. HardieSmart™ ZeroLot wall system also offers a higher property value for the same block of land by providing fully detached dwellings and increased internal liveable space. For instance, on every 10m wall length you gain 2.45m² of internal space per dwelling#.

SIMPLIFIED CONSTRUCTION. HardieSmart™ ZeroLot wall system is an alternative to conventional brick walls. By removing excess material and trades, HardieSmart™ ZeroLot wall system simplifies construction and gives you a complete solution with all James Hardie components covered by the one product warranty.**

# Compared to a standard brick veneer wall of 230mm in wall thickness
** Terms and conditions apply and does not cover installation.
