Composite decking for your patio – why is it the best choice in 2025?

What exactly is a composite decking board?

At first glance, it resembles traditional timber, but it has much more to offer. A composite decking board (WPC – Wood Plastic Composite) is made from a combination of:

• wood flour (approx. 30–60%)

• plastic (most commonly HDPE or PVC)

• additives that improve durability, colour and resistance to UV radiation

The material is formed into boards with a uniform structure. They resist external factors and require no maintenance.

What types of composite decking boards are available?

Composite decking boards can be divided according to their construction:

Solid board

• Heavier, more substantial and durable, ideal for heavy loads and intensive use; more expensive, but long-lasting.

 Hollow board

• Lighter and cheaper, strong enough for domestic terraces; may require end caps and better ventilation.

Composite decking boards – all the benefits in one place.

There’s a good reason why this material is growing in popularity year after year. Here’s a list of the benefits of composite decking boards – and it’s no marketing spin.

1. No maintenance

There’s no need to oil, paint or protect the boards. Simply wash off dirt with water and you’re done. Your terrace will always look good.

2. Highly weather-resistant

Rain, snow, frost and scorching sunshine – none of these conditions are a problem for composite. It won’t rot, grow mould or warp.

3. Long lifespan

Composite decking boards can last up to 25 years. It’s an investment that really pays off.

4. Modern appearance

The range of colours and textures is so varied that you can easily match the boards to the style of your home, garden or furniture. Looking for a Scandinavian, rustic or modern look? No problem.

5. Safety

Composite decking boards are slip-resistant and splinter-free, making them an ideal choice for families with children and dog owners.

6. Sustainability

More and more manufacturers are using recycled materials. By choosing composite, you’re supporting the environment.

What about installation?

Installing a composite decking terrace isn’t as difficult as it might seem. Here’s a basic outline:

Step by step:

1. Prepare the sub-base – usually concrete, patio slabs or composite joists.

2. Lay the joists – leaving the appropriate spacing (usually 35–40 cm).

3. Screw down the boards – using a fixing clip system (so the screws are hidden).

4. Fit the trims and finishing pieces – to give the whole terrace a neat appearance.

Installation time: 1 to 3 days, depending on the size of the terrace and your experience.

What about the price?

How much does a composite decking terrace cost?

In 2025, composite decking board prices range on average from:

• 180 zł to 350 zł/m² – for materials only

• +50–100 zł/m² – installation accessories (clips, joists, trims)

• +100–200 zł/m² – if you hire professionals to install it

By comparison, a tropical hardwood deck (e.g. bangkirai) can cost as much as 600–700 zł/m² with maintenance every 1–2 years. Composite? One cost – and peace of mind for years to come.

How do you choose a good composite decking board?

Not all boards are created equal. Before buying, check:

• Board density – the higher it is, the better the quality

• Type of material – HDPE is more flexible and durable

• Surface type – better grip means greater safety

• Certifications and warranty – reputable companies offer warranties of up to 20 years

Pro tip: Avoid cheap Chinese alternatives – they are often brittle, fade in the sun and can delaminate.
