FREQUENTLY ASKED QUESTIONS2017-06-06T01:38:49+00:00
How do you maintain composite wood?2023-01-06T18:16:57+00:00

To maintain composite wood, it’s important to keep it clean and free of debris. This can be done by regularly sweeping the surface with a soft-bristled broom or using a garden hose to wash away any dirt or grime. Additionally, you must periodically inspect the composite wood for signs of damage.

How long does composite wood last?2023-10-25T23:54:02+00:00

Composite wood can last for a long time, but the specific lifespan will depend on various factors, including the quality of the material, the intended use of the product and the way it’s maintained. In general, however, composite environmentally friendly timber can last for 30 years or more. COEN composite wood products feature industry-leading warranties of up to 25 years!

Can composite wood be painted or stained?2023-01-06T18:14:47+00:00

Yes, composite wood can be finished similarly to natural wood. This means you can use a wide range of paint and stain products to give it the desired colour and appearance.

Can you build furniture with composite wood?2023-01-06T18:14:20+00:00

Composite wood is not as strong as hardwood, but it can still be used to make furniture. You must use the right glue and proper joinery techniques to keep your furniture together. Composite wood has long since been used to create cabinets and tables.

Does composite wood need to be sealed?2023-10-25T23:56:43+00:00

No, composite wood does not need to be sealed because it’s already treated with a waterproofing agent, which protects it from moisture damage. This makes it ideal for environmentally friendly decking construction.

Does composite wood hold up?2023-10-25T23:58:20+00:00

Yes, composite wood can be very durable and long-lasting. It’s resistant to many factors that can damage natural wood, such as rot, insect infestation and moisture. This makes it a popular choice for outdoor applications, such as environmentally friendly decking and furniture.

What is composite wood made of?2024-05-02T00:04:40+00:00

The composition of composite wood can vary depending on the manufacturer and the material’s intended use. COEN composite wood, however, is made by mixing 60% wood powder with 28% HDPE and 10% additives, creating a sustainable form of environmentally friendly timber. This mixture creates a robust and durable material often used in decking, cladding, screening, fencing or making timber sleepers. Browse our product range today!

What is Composite Wood?2018-07-12T01:47:38+00:00

Composite wood is  the future of building; which is often referred to as Wood Plastic Composite (WPC), Plastic Decking or Composite Decking. Composite wood is made via a process of combining recycled wood flour, plastics and binding agents, then extruding them into various products. COEN is a co-engineered product which uses the latest technology to produce a superior and consistent composite wood.

What is COEN Composite Wood made from?2021-06-22T04:17:17+00:00

The journey for manufacturing COEN Composite Wood starts with high quality base materials. There are 3 basic ingredients. Wood flour, made from recycled and rejected manufactured wood products, recycled plastics with HDPE compounds and additives for bonding, UV & insect protection etc. Each raw product is tested to ensure the purest of raw material, and rejected if any substance such as Asbestos, Formaldehydes are present. By mixing 60% wood powder with 30% HDPE and 10% additives, then extruding through our modern CNC high pressure / temperature extrusion machines, you end up with a high quality COEN product.

Is COEN recycled?2018-07-12T01:55:34+00:00

Yes.  COEN products are made from 88% recycled product, in wood flour and HDPE plastics.  As part of our manufacturing process, we also recycle off cuts and any rejects from this process.

Are the products consistent?2020-07-22T05:28:14+00:00

All COEN products are manufactured with premium raw products that are tested, then fed into the latest extrusion machines to produce products with consistent width, thickness, patterns and colours. This consistency gives builders less headaches when installing your COEN products, as there is no warping or twisting. Saving you time and money

Does it warp?2017-06-06T02:30:57+00:00

COEN Products do not warp, twist or bend when stored and installed correctly.

Why do I need to leave a gap?2017-06-06T02:15:33+00:00

All Composite Woods have a lineal thermal expansion rate.  As COEN products use high quality raw products and 60% wood flour, their lineal expansion isn’t as high as other composite wood.  We suggest a 2mm to 4mm gap at each end of your COEN product to cater for any thermal expansion.

Does it expand?2017-06-06T02:15:47+00:00

Only linearly, COEN products don’t grow thermally in width and thickness.

Will it splinter or crack?2017-06-06T02:16:03+00:00

Due to the raw material and our manufacturing processes, COEN products won’t splinter or crack.

What lengths are available?2021-06-22T04:19:35+00:00

COEN products come in standard lengths; however, if you require a specific length, please let us know and we can have it customised.

COEN Decking comes in a standard 5.4m length; or can be cut to size with a minimum order quantity.  COEN cladding comes in a standard 4m length; or can be cut to size up to 4m.  Our Fencing panel range comes in a standard 1.83m length.

Will my product fade?2018-07-12T01:54:33+00:00


Typically COEN products only fade 3% to 5% within the first 3 months, after this time the colouring remains stable.

I want to paint it. Is that ok?2018-07-12T01:57:32+00:00

Absolutely, and there are a few different methods and paint types you can use.  However, composites are both financially and time effective; as such there is no need to paint or seal COEN products.

How do you clean it?2018-07-12T01:59:02+00:00

Cleaning COEN Composite Wood is simple – please see the Care & Maintenance sections in each product guide.

Does it get mouldy?2018-07-12T02:00:03+00:00

No – COEN composite wood is an extruded product that has built-in additives that give the products stability with an anti-mould agent.  Like any product, if water does pool for long periods, mould will form; however, with COEN Composite products this mould does not penetrate the product surface; therefore it is easy to clean off.

Do I need to oil or stain it?2018-07-12T02:01:38+00:00

No – this is the beauty of COEN Composite products. Once installed, sit back, admire and enjoy the time you now have rather than re-staining as needed with wood products.

Additionally, 18 months down the track you will have saved $1,000 per 20sqm, due to no ongoing staining, oiling or painting requirements.
