Outdoor wooden decking These are a group of flooring materials specifically designed for outdoor spaces such as balconies, gardens, swimming pools, outdoor walkways, or terraces, with the core requirement being resistance to sun, rain, high humidity, temperature changes, and long-term weather effects.

This group currently includes both specialized natural wood decking and outdoor wood-look decking (synthetic materials).

Currently, there are five main types of outdoor decking that are highly regarded for their durability, aesthetics, and quality, suitable for various budgets and usage needs.

"Outdoor wood-plastic composite decking is a composite material composed of wood powder, HDPE resin, and additives, achieving dimensional stability with an expansion rate of only 0,1%," according to the European Committee for Standardization (CEN) 2025.

Decking

Outdoor wood-plastic composite (WPC) decking is manufactured using extrusion technology.It is composed of 55-60% wood powder, 30-35% HDPE plastic, and 10% additives. This combination creates a product that possesses both the beauty of wood and the outstanding characteristics of plastic, with a low expansion rate of only 0,1%.

There are currently two popular types of outdoor wood-plastic composite decking on the market:

1. Single-layer plastic Laminate flooring: Without a surface coating, it has a lifespan of approximately 7-10 years at an affordable price. This flooring is suitable for home gardens, apartment balconies, or small cafes. The product loses about 10%-25% of its color in the first 3 months, after which the color remains stable.
2. Double-layered polymer-coated wood-plastic composite flooring (2-layer wood-plastic composite flooring): The surface is coated with a 0,1-0,8mm thick layer of polymer. The product has a lifespan of 15-20 years and maintains its color stability throughout its use.
