The Most Extensive Composite Cladding Range in Australia
At NewTechWood, we know what our customers want, which is why we’ve developed Australia’s most extensive range of castellation wall cladding.
We offer three distinct castellated profiles to meet any of your design needs, providing a striking aesthetic that blends contemporary style with exceptional durability.
3-rib cladding panel (UH58)
The premium 3-rib (UH58) with a 50mm rib delivers high-impact visuals in a curated selection of popular colours to complement a broad range of styles and decor. The range also includes an ebony charred wood-look finish for a distinctive texture, providing the ever-popular appearance of traditional charred timber with the low-maintenance benefits of composite materials.
5-rib cladding panel (UH61)
Our 5-rib panel (UH61) has a 25mm rib and is well-known across Australia, widely utilised as a durable and stylish architectural addition to commercial and residential projects. Available in three sought-after colours: Ipe, Canadian Cedar and Ebony. This panel can effortlessly complement any number of themes and design inspirations.
4-rib cladding panel (UH93)
We’ve combined two of the panels you love and created our very own unique 4-rib panel (UH93) with both rib widths, 25mm and 43mm, for seamless integration into any architectural scheme you can think of. Suitable for both internal and external applications, it enables a cohesive design language across diverse spaces.

What NewTechWood Customers Have To Say
I couldn’t be happier with my first composite decking & wall cladding attempt. The great advice & service allowed me to achieve this amazing result. I love it & the concealed fittings. I found this a fairly easy DIY project & still smile every time I look at the end result. Thanks
We are very happy with our new tech product. We are still in the construction process, but it is looking amazing. We will send some photos when it is finished. These wide rustic boards are just perfect for the style we are trying to achieve.
Amazing material! We love our deck so much, all of our friends make a nice compliment each time they visit us. Thank you.
We’re still completing our new home & are yet to install the roof & balustrade on our front deck, but our little back deck area is great! The decking is so easy to look after & everyone comments on how great it looks, especially the colour. So happy we decided to use NewTechWood Blackbutt decking for our new home.
My dog loves laying around on these boards in the shade on a hot summers day. If only she could cook the bbq.
Great product, easy to worth with & the results are amazing. We can now use our previously dull & dirty unit balcony everyday as it’s also really east to keep clean. Highly recommend it!
We absolutely love our new space, no screws visible gives a very neat, stylish and streamline look. The Blackbutt selection is perfect for the coastal feel.
Great for non-professional ‘handy-people’ – NewTechWood is very simple to install, takes the guess work out of the construction process, and doesn’t require any maintenance. Building in a BAL25 area limited what we are able to install, and NewTechWood ticked all the boxes. We are so pleased with the stunning results (& a little proud of ourselves for doing it all in-house, too!)
We used the Canadian Cedar cladding and Coastal Beech decking to complete our pool area, we are so happy with the product and the results. So easy to clean and no major upkeep needed, also no risk of tanning bleeds on our light coloured coping tiles. Very impressed.
Decking system was easy to install using the t clip system, product was easy to work with and looks great once completed
Sensational product: I did lots of research, and I could not be happier – It’s a perfect product, no more maintenance than vinyl floors, nice to walk on, and it looks sensational. It has only been down 18 months, but as good as the first day. No more sanding or oiling for me. One of my best renovation decisions.
Backed Up With a 25-Year Warranty
We stand behind our products with confidence. What’s why we offer you peace of mind knowing that all NewTechWood composite timber products come with Australia’s most comprehensive composite timber warranty. To make sure your deck, fence, screening or cladding is performing its best, it’s important that installation follows the guidelines, including the recommended secret-fix clip systems and joist spacing.

How does composite cladding compare to traditional timber cladding?

NewTechWood composites can be cut, nailed, drilled and screwed using standard woodworking tools, making them accessible for both professional installers and experienced DIYers. Following the Installation Guide ensures proper technique and helps protect warranty coverage.
Does Castellation cladding require painting or staining?
No. Castellation cladding is supplied with a fully finished surface and doesn’t require painting or staining. Its composite coating provides UV and weather resistance so the cladding maintains its appearance without ongoing surface treatments.
