Building a deck is an investment that takes on new significance in 2026. With the climate changing, summers getting warmer and more people wanting a low-maintenance place to relax, WPC (Wood Plastic Composite) systems have become the undisputed standard. But the wide range of products on the market can be overwhelming. As experts at Gardpol.pl, we have put together a detailed comparison of three of our flagship models of composite decking: Select, Duo and Premium. Find out which one is best suited to your garden.
Deck design in 2026 – why choose composite?
Before looking at specific models, it is worth understanding why 2026 is the year of composite. Beautiful though traditional timber may be, it needs costly and time-consuming maintenance every year. In the age of smart living, people are looking for ‘ install and forget ’ solutions.
Composite decking available from Gardpol combines wood flour with modern HDPE polymers. The result is a product that:
- Does not rot or decay even in high humidity.
- Does not need painting or oiling.
- Is safe for bare feet – no splinters is a key benefit for families with children.
- Is eco-friendly – we use recycled materials to help protect the planet.
SELECT composite decking – Stability and tradition.
The Select model is the cornerstone of our range. This classic-profile composite deck board has remained popular for years. Its thickness (25 mm) makes the structure exceptionally rigid, which is essential for intensive use.
Appearance and finish.
Select decking is grooved on both sides. One side has a wide groove, the other a narrow one. Its classic appearance is a perfect fit for traditionally styled homes. The grooves also serve an important practical purpose: they help water drain from the deck surface.

Why choose the Select model in 2026?
The 2026 trend is a return to ‘safe minimalism’. With its slip resistance (class R11/R12), Select is ideal around swimming pools, on outdoor steps and on uncovered decks. It is an economical option without compromising on durability.
-
Suitable for: Large domestic decks and public buildings.
-
Key benefit: Outstanding resistance to mechanical loads.
DUO composite decking – The queen of design and functionality.
If you are looking for a product that gives you the freedom to choose even on installation day, the Duo model is unbeatable. At 148 mm wide, it covers the deck more quickly and gives it a modern, substantial look.
2 in 1 innovation.
What sets the Duo range apart is its combination of two different styles. On one side, it has a 3D wood-effect grain texture, while the other has classic fine grooves.
2026 trend: Personalisation.
In 2026, customers do not want off-the-shelf solutions – they want something unique. Duo decking lets you play with the design. You can lay the whole deck with the wood-grain side up, use the grooved side as a border (a ‘picture frame’), or simply turn the boards over when renovating after a few years, completely changing the look of your outdoor retreat.
-
Key benefit: At 148 mm wide, it means fewer joins and quicker installation.
-
Appearance: An ultra-natural look thanks to embossed grain technology.
PREMIUM composite decking – High-end elegance.
For the most discerning customers, we have created the Premium model. In 2026, this decking sets the standard for outdoor luxury. If you want your deck to be indistinguishable from exotic bangkirai or teak wood, this is the choice for you.
Deep embossing technology.
The Premium model features advanced Deep Embossing technology. The wood grain is not simply printed on, but deeply embossed into the material. This creates a striking interplay of light and shadow across the deck, lending it an elegant appearance.
Colour durability.
The Premium range offers increased resistance to UV radiation. In 2026, as the sun grows stronger, colour stability is essential. Premium decking retains its colour saturation for many years and does not fade to grey as quickly as natural timber.
-
Suitable for: Modern residences and luxury apartment balconies.
-
Key benefit: Unrivalled visual appeal and prestige.

Installation accessories – the heart of your deck.
At Gardpol.pl, we know that the decking is only half the story. The durability of your deck in 2026 depends on what lies beneath it. When you choose our systems, you can also get professional accessories:
- Composite and aluminium joists: These provide a stable base. In 2026, we particularly recommend aluminium joists for low-profile installations.
- Installation clips (hidden fixing system): They mean you will not see a single screw on the deck surface. For a flawless finish.
- Finishing trims: Corner and straight trims that complete the structure and protect the edges of the boards.
How to care for your composite deck in 2026
Although composite decking is virtually maintenance-free, it is worth following a few simple guidelines to keep it looking its best for decades:
- Occasional cleaning: Water with a mild detergent or a pressure washer will do (keep it at a suitable distance).
- Removing stains: Remove greasy barbecue stains as soon as possible to prevent them from penetrating the wood-flour structure.
- Sweeping: Regularly removing leaves and sand helps prevent damp patches forming beneath garden furniture.
Summary.
Choosing composite decking in 2026 is an investment in peace of mind.
- Choose Select, if you value strength and classic slip resistance.
- Choose Duo, if you like a change and want a wide, modern deck board.
- Opt for Premium, if you want your deck to be a work of architectural art.
