The same finish, the same six colours and the same installation system. The difference lies inside the board and in the performance your project requires.
| Criterion | Hollow | Solid |
|---|---|---|
| Dimensions | 2300 × 140 × 24 mm | |
| Structure | Board with internal cavities, lighter | Board filled across the whole section |
| Weight | Lighter, easier to handle (5.58 kg) | Heavier (9.58 kg) |

NA — Not assessed.
Yes, slightly and predictably. It is a composite containing wood fibres: in the first few months, the colour lightens to a more natural shade and then stabilises. From then on, the colour and texture remain virtually unchanged.
Hollow boards are lighter and suitable for most projects. Solid boards offer greater impact resistance and lower water absorption in the declared tests, and are recommended for intensive use or demanding conditions, such as extreme cold or high humidity.
The choice depends on how the decking will be used, the site conditions and the installation method. Our team can help you choose the right profile.
Yes. Both profiles have the same dimensions, colours and fixing system, so they can be combined in the same project. Installation must follow the applicable technical guidelines.
Yes. CDECK Original® resists moisture, salt and chlorine and achieves slip resistance Class 3 in wet conditions, in both directions tested.
It is important to ensure proper drainage and regular cleaning. The product is not designed for permanent submersion.
Yes, like any outdoor flooring. The surface temperature depends on the colour, sun exposure and installation conditions. Light shades stay cooler than dark ones, and hollow boards tend to heat up less than solid boards.
For spaces with a lot of sun, choose a light colour such as Beech Beige and consider creating shaded areas.
Yes, with proper ground preparation and a suitable substructure. The boards must not be laid directly on the soil.
The supports must be stable, with drainage and ventilation underneath, in line with the installation manual.
Boards can be produced in lengths from 1.8 to 3 metres, on request. Talk to our team to confirm the supply conditions.
For routine cleaning, use water, a neutral detergent and a soft brush. Remove spills as soon as possible and don’t let debris build up between the boards.
For specific stains or pressure washing, see the instructions in the cleaning and maintenance guide.

The main difference is the look. Original® has a classic, grooved finish with clean lines and is available as a hollow or solid board. WUUDE® recreates the look of natural wood.
WUUDE® is also capped, which makes cleaning even easier: for everyday cleaning, a mop is all you need.
Discover CDECK WUUDE®
The patented Quick-Fix® system clicks into place and lets the decking accommodate the natural dimensional changes of the material over time. With Quick-Fix PRO® clips, boards can be removed individually, for example to reach an inspection chamber or for a deeper clean.
