Building a sustainable home starts with the exterior. The right cladding keeps heat in during winter, shields your frame from rain, and shapes the look of the whole project.
Sustainable external cladding also helps shrink a home’s embodied energy and long-term environmental footprint. Melbourne’s climate adds another layer of decision-making. Mild winters, hot days in summer and steady rainfall call for durable, low-maintenance materials that won’t deteriorate quickly.
Below, we break down eco-friendly cladding materials that balance durability, performance and sustainability.
A few traits signal whether a material will perform well over its lifespan. Look for:
These factors support both environmental goals and long-term resale value.

Embodied energy is the total energy used to make a building material, from raw extraction through manufacturing and transport. Materials with lower embodied energy require fewer resources to produce, which helps reduce the overall environmental impact of a home. |
Durable, stable and suited to bushfire-prone areas.
James Hardie™ fibre-cement cladding is one of the most widely used sustainable choices in Melbourne builds. It’s made from cement, sand and cellulose fibre, giving it toughness without the upkeep that natural timber demands. Most importantly, it has a long lifespan. Meaning fewer replacements and less waste over the life of your home.
Plaster Wholesalers currently stocks a wide selection across modern and coastal styles:
Fibre-cement works well for homeowners wanting eco-friendly cladding materials without high maintenance. It resists rot, swelling and termite damage, keeping replacement cycles low. When installed with the right cavity system and fixings, it also provides strong weather performance in line with NCC requirements.
The lighter weight compared to masonry reduces transport emissions, while stable sheets cut down on site offcuts. Builders appreciate the simple fixing patterns and predictable board movement—making install time more efficient.
Recycled materials engineered for long-term performance.
NewTechWood™ cladding combines 95% recycled content (including reclaimed timber fibres and recycled HDPE plastics) into a stable composite board. It’s designed to give the warmth of timber without the upkeep, making it a strong fit for sustainable homes with busy maintenance schedules.
Plaster Wholesalers stocks a range of NewTechWood™ products, giving homeowners an option that’s both durable and environmentally conscious.
Benefits for sustainable builds include:
Composite cladding suits homeowners who want a timber-look façade without the ongoing upkeep or environmental impact of frequent refinishing.
Lightweight fibre-cement systems designed for stable, long-term performance.
Plaster Wholesalers also stocks Cemintel™ cladding, giving builders and renovators another reliable fibre-cement option. Cemintel boards are made for modern façades and offer predictable performance in Melbourne’s changing conditions.
Popular ranges include Cemintel Territory™, Urban™ and Surround™, each offering different textures and colours without the need for heavy on-site finishing.
Builders often choose Cemintel for:
Cemintel is a strong fit for sustainable homes that want a clean architectural look with low ongoing upkeep.
| Cladding option | Embodied energy | Lifespan | Maintenance | Key sustainability benefit |
| Fibre-cement (James Hardie) | Low–medium | Long | Low | Durable sheets mean fewer replacements and reduced lifetime waste |
| Composite (NewTechWood™) | Low | Long | Very low | High recycled content (up to 95%) supports low embodied energy |
| Fibre-cement (Cemintel™) | Low–medium | Long | Low | Pre-finished panels reduce on-site painting and cut down site emissions |
Melbourne’s mix of cool winters, hot summers and consistent rainfall means your cladding must handle fast temperature changes without swelling or cracking. Fibre-cement options from James Hardie handle this well thanks to board stability and engineered weather resistance.
For homeowners looking to cut long-term environmental impact, durable materials matter most. Minimal swelling, low rot risk and long service life reduce the need for repainting and replacement—key contributors to low embodied energy across a home’s lifespan.
Plaster Wholesalers stocks a wide range of James Hardie™, NewTechWood™, and Cemintel™ cladding products across both our Hoppers Crossing and Somerton branches. You can pick up or arrange delivery across most of Victoria.

Which sustainable external cladding lasts the longest?
Fibre-cement systems such as James Hardie™ and Cemintel™ typically have the longest service life thanks to their resistance to rot, swelling and pests. Composite boards like NewTechWood™ also offer long-term durability with very low maintenance.
Is NewTechWood™ considered an eco-friendly cladding material?
Yes. NewTechWood™ uses up to 95% recycled materials, including reclaimed timber fibres and recycled plastics. This contributes to lower embodied energy while still achieving stable performance in exterior applications.
Does fibre-cement count as low embodied energy cladding?
Fibre-cement sits in the low–medium range. Even though energy is required to produce the boards, their long lifespan and low maintenance help reduce environmental impact over time.
Can I mix cladding types on the same build?
Yes. Many projects combine composite cladding with fibre-cement boards to add texture and define different parts of the façade. Follow manufacturer guidance for junctions, cavities and weatherproofing.
