Composite decking has become one of the most popular outdoor flooring, thanks to its durability, low maintenance and modern aesthetic.
But what is the actual price of composite decking in 2026? For CDECK composite decking, the indicative board prices start at 19.07 € for the CDECK Original hollow board and 20.21 € for the CDECK WUUDE.
These figures provide an initial reference, but the real cost per square metre depends on several factors — and that is exactly what we will cover in this article.
Factors That Influence the Price of Composite Decking
The price of composite decking per square metre is not fixed and can vary considerably. To better understand the investment required, it is important to be aware of the main factors that impact the final cost.
Product quality
Not all composite decking is the same. Products vary significantly in terms of characteristics, durability, performance and warranties, even when they are all referred to as composite decking. This variation means prices can differ considerably from one product to another.
Installation type
The way the decking is installed has a direct impact on the cost. It can be as straightforward as screwing down substructure profiles and clipping the boards in place, or it may require self-supporting substructures, adjustable bases and specific adaptations for residential or commercial areas. Each installation type affects the final project cost.
Area complexity and special accessories
The decking may be laid on a uniform rectangular surface or on an area with cut-outs, curved shapes, level changes or steps. In these cases, finishing profiles, stair profiles and other accessories will be required, which increases the overall project cost.
Average Price per m² of CDECK Composite Decking in Portugal (2026)
Before presenting the material estimates and prices, it is important to understand the three CDECK installation types, which define how the decking is applied and influence the quantity of materials required:
Type 1 – Regular Base (screw fixing)
For level and drillable bases, where the Quick-Fix joists rest fully along their entire length.
Type 2 – Irregular Base (screw fixing)
For irregular and drillable bases, where the Quick-Fix joists cannot rest fully along their entire length.
Type 3 – Raised Installation and/or where screw fixing is not possible
Ideal when the base cannot be drilled or the floor level needs to be raised. Can be installed over protective membranes, on compacted ground, etc.
Below is the indicative material estimate per m² and the recommended retail prices for each CDECK installation type. The tables detail indicative quantities for residential use — private areas with moderate footfall, such as gardens, balconies or pool surrounds in private homes — and commercial use — spaces subject to higher levels of use, such as outdoor dining areas or pool surrounds in hotels and resorts. This breakdown helps identify the products and reference values associated with each installation scenario.

Note: These figures are indicative only and are intended as a reference. The final cost of composite decking per m² will depend on the installation type, accessories used and the specific characteristics of the project.
The price of composite decking in Portugal is never fixed. It varies according to the product type, installation type and the specific characteristics of each area, such as geometry, cut-outs and the need for accessories. Having a reference for board prices and the indicative material estimate per m² helps with planning, but every project will always have its own unique costs.

Frequently Asked Questions
Every project is unique. The final cost depends on several factors, including:
- Product type: CDECK Original Hollow Board, CDECK Original Solid Board or CDECK WUUDE Encapsulated Hollow Board.
- Installation type: Regular Base (Type 1), Irregular Base (Type 2) or Raised Installation (Type 3).
- Area characteristics: presence of cut-outs, steps, curved shapes or the need for special accessories.
The Quick-Fix installation system has 3 different types:
- Type 1 — Regular Base (screw fixing): for level and drillable bases, where the Quick-Fix joists rest fully in place.
- Type 2 — Irregular Base (screw fixing): for drillable bases with irregularities, where the joists cannot rest fully in place.
- Type 3 — Raised Installation or without screw fixing: when the base cannot be drilled or the floor level needs to be raised, such as on compacted ground or over protective membranes.
IHT’s material estimate per m² distinguishes between:
- Residential use: private areas with moderate footfall (gardens, balconies, pool surrounds in private homes).
- Commercial use: public or business areas with higher levels of use (outdoor dining areas, walkways, pool surrounds in hotels or resorts).
The difference is not in the board price itself, but in the quantities of joists, clips and screws required, which influences the final price per m².
The material estimation and reference price tables, available in the technical data sheet, provide a starting point. For an accurate quote, taking into account the area geometry, installation type, and additional accessories, consulting an IHT specialist or running a simulation is recommended.
