Frequently Asked Questions (FAQ's)

CDECK decking is an innovative range of outdoor flooring resulting from several years of research and development of high-performance composite materials. Developed to withstand the most demanding weather conditions, CDECK decking is the ideal solution for terraces, balconies, gardens, pools, esplanades, marinas, etc., whether in private or public high-traffic areas. This outdoor flooring is manufactured in Portugal and comes in two distinct ranges, CDECK Original and CDECK WUUDE. Both combine aesthetics, resistance, and durability with ease of installation and maintenance, making them the ideal choice for those seeking high-quality and long-lasting outdoor flooring.

Both CDECK ranges are made from PVC because, compared to other polymers, PVC offers high chemical and mechanical resistance, good thermal stability, and high resistance to radiation and other weather elements. Its versatility and longevity make it suitable for various products, from the construction sector to healthcare.

Being made from PVC, CDECK offers a resistant and durable solution for outdoor flooring.

In the case of CDECK, the wood percentage is around 50%.

Wood acts as a functional filler in the mix, being the cheapest component of the raw material. High wood percentages lower the price of composite decking but increase moisture absorption and thus dimensional variation. On the other hand, low percentages improve moisture absorption but reduce the mechanical performance of the decking.

Each manufacturer finds their balance between quality and price. In the case of CDECK decking, the percentages of wood and all other components of the raw material have been defined to achieve a composite deck where quality and durability are valued above all.

Indeed, just as much as the wood or polymer, it is the other additives that create significant performance differences among various composite decks.

By adding elements such as impact modifiers, UV filters, antioxidants, stabilisers, compatibilisers, etc., it is possible to obtain decks that, while looking similar, exhibit extraordinarily different characteristics. Thanks to rich and balanced formulations, composite decks like CDECK can offer, for example, mechanical resistance 2 to 3 times higher than that of most competing composite flooring.

There are many types of composite decking, considering their composition and how they are produced. Besides these differences, there are other characteristics that allow them to be categorised differently.

Regarding board design, there are:

  • Hollow decks, which have interior holes to reduce weight;
  • Solid decks, which, as the name implies, are completely solid.

Regarding material layers, there are:

  • Monomass decks, where the boards are made with a uniform mixture of materials, such as CDECK Original;
  • Partially encapsulated decks, which have a main body made with a uniform mixture of materials and a top layer in a different material;
  • Fully encapsulated decks, which have a main body made from a uniform mixture of materials and an outer layer in one or more materials, such as CDECK WUUDE.

CDECK decking comes in various forms depending on the range.

In the CDECK Original range, there are both hollow and solid boards, all of which are monomass.

In the case of CDECK WUUDE, there are only hollow boards, which are fully encapsulated with two distinct materials, meaning they have a monomass core in a composite similar to that used in CDECK Original decking, and two layers, one lower and one upper, made from two special polymers.

Advantages of solid boards:

  • Solid boards have greater mechanical strength than hollow decking boards, particularly in terms of impact resistance, and also have less dimensional variation due to moisture.

Disadvantages of solid boards:

  • Solid boards (if made with the same recipe as hollow decking boards, as in the case of CDECK Original decking) are more expensive because they contain more raw material.
  • As they have a greater mass and a smaller exposed area, solid boards tend to heat up more than hollow decking boards due to solar radiation.

The choice between hollow and solid boards depends on several factors, starting with product quality.

For most composite decks on the market, especially those made with Polyethylene or Polypropylene, the use of hollow boards is not recommended in any situation because the mechanical strength of the deck board is usually very low (between 25 to 50% of the strength of CDECK decking).

In the case of CDECK decking, the use of solid boards is only justified in very particular situations, such as:

  • Extremely cold environments, where temperatures can easily drop below -20ºC;
  • Environments with constant high humidity, such as saunas or indoor pools with consistently high humidity and temperatures;
  • Areas with a high risk of total or partial submersion of the boards, or areas where water is likely to enter the hollows;
  • Areas with a high risk of mechanical impacts, such as restaurant zones where beer barrels, gas cylinders, etc., are unloaded.

The solid and hollow boards of CDECK Original decking have the same configuration, allowing both solutions to be combined in the same installation. It should be noted, however, that CDECK hollow decking is more resistant than most solid decks on the market.

Semi-encapsulated and encapsulated decking boards are a relatively recent solution compared to monomass boards, introduced with different objectives.

The main goal, common to all manufacturers, was to achieve different aesthetic presentations closer to the appearance of natural wood, as monomass decking boards typically have a uniform finish.

Another objective for many manufacturers was to allow the use of lower quality materials inside the boards, thus reducing costs.

As with monomass decks, there are also significant differences in presentation, performance, and durability in semi-encapsulated and encapsulated decks, depending on the materials used and manufacturing methods.

In the case of CDECK Original (monomass) and CDECK WUUDE (encapsulated) decking, the main differences lie in aesthetics, liquid absorption, and scratch resistance, with the core of CDECK WUUDE decking boards made from materials similar to those used in CDECK Original decking, to ensure similar performance and durability.

Aesthetically, CDECK WUUDE decking boards feature a unique organic design similar to natural wood, while CDECK Original decking has a more sober and uniform design.

In terms of liquid absorption, CDECK WUUDE decking boards have top and bottom faces that are easier to clean than those of CDECK Original decking, which, having exposed wood particles, behaves similarly to wood. For example, in the presence of oil or other fats, it will absorb these materials and display a stain for some time.

Regarding abrasion or scratch resistance, CDECK Original boards, if scratched aggressively, will maintain their appearance, with the scratch being practically invisible since they are made of a single mass. In the case of CDECK WUUDE decking, if the scratch is aggressive enough to penetrate the top layer, it will expose the inner material, making the scratch more visible.

Regarding the various semi-encapsulated and encapsulated decking board options on the market, it is very difficult to ensure non-slip boards when the top layer is 100% polymeric, so most of these products are not non-slip.

Contrary to most semi-encapsulated or encapsulated decks, CDECK WUUDE composite decking stands out for its exceptional non-slip capability, achieving Class 3 in the slip test, which is the required class for outdoor flooring in areas that may be wet. This performance from an encapsulated deck is very rare and is due to special processes developed by IHT, making it an ideal choice for outdoor flooring.

Abrasion or scratch resistance also varies greatly in these types of materials, with the majority of composite decks on the market being very “soft,” meaning they are very easy to degrade and scratch, which is very negative for outdoor flooring that will be subjected to all kinds of aggression.

In this aspect, CDECK WUUDE decking features an extremely resistant polymer layer, ensuring durability and longevity.

Another important aspect to highlight is that semi-encapsulated decking boards have a very high risk of warping because, with one waterproofed face and one face with exposed wood, they tend to absorb more moisture on the face with exposed wood, which will increase the likelihood of warping due to an imbalance in moisture content between areas of the board.

Advantages of CDECK Original relative to other composite decks:

  • It offers better mechanical performance (hollow decking is more resistant than most solid decks on the market, and 2 to 3 times more resistant than most hollow ones) due to its formulation and production method;
  • The boards can be custom-made (with lengths between 1.8 and 3m) to better suit each project;
  • It has greater dimensional stability and better abrasion resistance;
  • Variety of board colours (6);
  • Hollow and solid boards have the same configuration, allowing the two types of boards to be mixed in the same installation;
  • It offers a wide range of profiles and accessories that ensure solutions for almost all situations;
  • It has a patented fixing system that saves installation time, using only one screw per board and allowing individual board opening thanks to the pro intermediate clip;
  • Uses joists in PVC or Aluminium that ensure high stability and durability.

Disadvantages of CDECK Original relative to other composite decks:

  • It typically requires a higher initial investment.

CDECK Original decking is a semi-natural product, so variations in colour and texture are likely to appear over time. During the first few months after outdoor installation, the colour will gradually change until it stabilises. The final colour of the boards will take on a lighter, more natural tone than the original colour due to the absorption of water by the wood fibres. Once stabilised, the colour and texture will remain virtually unchanged.

Yes. CDECK decking, besides being free of knots and splinters, is an extremely non-slip flooring even when wet (Class C3).

Yes, it is also resistant to treatments used in pools.

Like any other material, CDECK Original decking heats up when exposed to solar radiation, with darker colours heating more than lighter ones. Compared to wooden decking, and if we compare similar colours, CDECK decking will heat up a bit more, but the difference is not very significant.

Hollow boards will heat up slightly less than solid ones due to allowing some ventilation inside.

The CDECK decking system has an expected lifespan of over 30 years.

CDECK, when installed and maintained according to the guidelines presented in the technical data sheet, has a warranty period of twenty-five (25) years for residential private space installations, or ten (10) years for commercial or public access space installations.

The CDECK fixing system is a unique and patented system. It is very easy to install and uninstall because it is a click system and requires only one screw per board. It consists of various types of clips for different situations, including a clip that allows individual board opening, whether to access a drain, a manhole cover, or simply to perform a deeper cleaning. In addition to these advantages, the fixing system allows the deck to float, ensuring greater adaptability of the flooring to dimensional variations, and thus greater dimensional stability over time.

PVC or Aluminium joists ensure greater durability because, in most cases, the joists are in direct contact with the ground, making them more susceptible to the effects of moisture, biological agents, etc. Additionally, they are in an almost inaccessible area for treatment or maintenance over time, hence the need to use materials that guarantee stability and durability without the need for maintenance, to ensure the longevity of the entire system.

If the board you want to remove is located at the edge of the deck, you should remove the end clips and proceed with removing the board normally. If the board is in the centre of the deck and does not contain intermediate pro clips, you should cut the intermediate clips using a grinder, and then reinstall the board with intermediate pro clips.

No. Since CDECK boards are made of WPC (Wood Plastic Composite), they contain wood, and if permanently submerged, they may undergo irreversible changes in their configuration due to excessive water absorption.

No, decking boards should never be installed directly on the ground. It is necessary to ensure an air gap between the boards and the ground, which is provided by the joists.

No, CDECK decking joists must be fixed to the ground or to other profiles that ensure a stable structure, as described in the technical data sheet.

Yes, provided it is installed with a stable structure, as described in the technical data sheet, ensuring soil compaction in the support areas and that the lower air gap is not obstructed, specifically by using a geotextile fabric.

No, it is absolutely essential to ensure the proper spacing between boards because temperature and humidity variations will cause dimensional changes in the boards. If the gaps indicated in the technical data sheet are not maintained, the deck may warp, lift, or break. However, due to the extraordinary mechanical performance of CDECK decking, it is more likely that the deck will force the materials around its perimeter to give way, potentially even breaking surrounding walls.

No. CDECK decking has been developed and tested as a system, where each component plays a specific role. Therefore, it should always be installed with the corresponding accessories and in accordance with the guidelines provided in the Technical Data Sheet, to ensure long-term durability and stability.

Yes, anyone can install CDECK decking, provided they have the right tools and some DIY aptitude, as the installation is easy. IHT provides a very comprehensive technical data sheet and online videos that explain step-by-step how to do it.

  • CTOOL
  • Rubber mallet
  • Drill
  • Screwdriver
  • Circular saw (with wood blade)
  • Measuring tape
  • Materials described in the Technical Data Sheet

Maintaining CDECK decking simply involves periodic washing to maintain its good appearance and to ensure that residues do not become permanently deposited.

CDECK decking should be washed using a high-pressure washer, ensuring a minimum distance of 30 cm between the nozzle and the boards, with a maximum pressure of 150 bar, always washing along the length of the boards. You can also use a mild detergent or a chlorinated solution (water with a bit of bleach) and a soft brush.
