When it comes to weatherboards, James Hardie weatherboards have earned their reputation across Australia and the globe as a top-of-the-line home cladding material. Known for their durability, versatility and distinctive appearance, James Hardie fibre cement weatherboards are a popular choice for both new builds and renovation projects. With a range of profiles, finishes and colours available, they can be used to achieve everything from classic weatherboard façades to more contemporary architectural designs.
In this blog, we’ll dive into everything you need to know about James Hardie weatherboards, including their key benefits, durability, weather resistance and what Perth builders should consider when choosing weatherboard cladding for a project.
What makes James Hardie weatherboards great?
As the pioneer of asbestos-free fibre cement products, James Hardie’s line of weatherboard cladding is locally manufactured here in Australia and has been carefully designed to weather through any environment. Compared to other traditional weatherboard materials, its fibre cement composition offers added durability that can help support and protect homes for years to come. Its key features include:
Versatile design options
One of the biggest advantages of James Hardie weatherboards is their versatility. Available in different profiles and designs, they can complement a wide range of architectural styles, from traditional and heritage-inspired homes through to modern and contemporary builds.
Easy to install
James Hardie fibre cement weatherboards are manufactured to consistent shapes and sizes, making them practical for builders to install and helping achieve a uniform finish. Their stable composition avoids many of the inconsistencies associated with timber and helps prevent shrinking, swelling, warping and rotting.
Weather-resistant
James Hardie weatherboards are designed to withstand the changing weather conditions experienced across WA. Fibre cement cladding provides a durable external surface that can handle exposure to sun, rain and changing temperatures, making it a practical option for homes in WA.
Fire-resistant
For homes in bushfire-prone areas, choosing appropriate external cladding is an important consideration. James Hardie weatherboards can be used in applications designed to meet bushfire construction requirements, with some systems suitable for Bushfire Attack Levels (BAL) of up to BAL40, subject to the specific product, wall system and installation requirements.
Resistant to splitting and warping
Unlike some traditional timber weatherboards, fibre cement weatherboards are not susceptible to the same splitting and warping issues associated with natural timber. This helps maintain a more consistent appearance over time, particularly when the cladding is exposed to changing temperatures and moisture.
Resistant to termite damage
Termites can cause significant damage to timber building materials, particularly when they gain access to external elements of a home. Fibre cement weatherboards provide a termite-resistant cladding option, helping reduce concerns associated with termite damage to the external wall surface.
Resistant to water damage
James Hardie weatherboards are designed to perform in external applications where they may be exposed to rain and moisture. Their fibre cement composition provides a durable alternative to materials that can be more vulnerable to moisture-related deterioration when improperly protected or maintained.
Thanks to its unique composition, it is perfectly suited to the varied WA climate and landscape, exposing homes to dry summers, wet winters, and coastal wind.
