Maximise speed of construction.

HardieSmart™ Intertenancy wall system is a high performance, lightweight system with a single layer design that is up to 30% faster to install than other comparable commonly available wall systems. 18% more compact, delivering significant increases in usable living space and increased land yield.

Made-easy specification.

HardieSmart™ Intertenancy wall system does not require a fire lining in-between tenancy frames; minimising risk of weather exposure to non-water resistant linings and unforeseen mould growth whilst simplifying complicated construction methods.

Simplified construction.

HardieSmart™ Intertenancy Wall System is an alternative to plasterboard, aerated concrete, blockwork and other options that involve multiple components. By removing excess material and trades, the HardieSmart™ Intertenancy Wall System simplifies construction and gives you a complete system with all James Hardie components covered by the one product warranty.**
