Composite, wood-plastic, or WPC – these are the different names used at our market for materials with different composition. In the case of our Terafest composite wood, it is a mix of HDPE polymer and sawdust from sustainably managed (PEFC certification Nr. PEFC/. 08-32-0018) forests. Not a single tree has to be cut down for our composite deckings, because we buy the offcuts which are then turned into sawdust.

The Terafest composite wood is, due to resistance to adverse weather conditions, an increasingly popular material, especially for deckings. In winter, when the deckings are exposed to extreme temperatures, snow and moisture, Terafest proves to be the ideal choice. It has a longer board life and fewer maintenance requirements compared to the traditional timber.

No WPC is the same

If you decided for a WPC material, be aware that the quality of all products is not the same and that frequently a product appears on the market of unknown origin and quality. It isn’t at all easy to tell good WPC boards. The price given by the seller might not be a sufficient quality guarantee. In China alone, around 200 companies were established in the last three years which manufacture WPC boards of various qualities. This is the toll of the high demand for this practical novelty. You also hear it from disappointed customers: “With increased frequency we are approached by people who had their decking made from hollow WPC boards from some no-name manufacturer and are now disappointed with its quality. It is not uncommon that these boards get completely deformed after just a couple of years and the customers turn to us with a request to have them replaced with ours,” Petr Hromek, a sales representative of WPC – Woodplastic notes.

We believe that it is only a question of time when the good products find their place in the market and the poor quality ones will end. In western countries, such as France and Germany, where these products have been present on the market for longer, the problems with poor quality boards completely disappeared. The manufacturers brand and the quality of the goods are the decisive criteria for the customers there when buying WPC deckings.

The North American manufacturers are the market leaders who came up with the idea of producing deckings from WPC boards. They have not only many years of experience, but they also massively invested into research and new technologies. They keep their processes and the material composition highly secret. Our company has decided to join forces with high quality and bought the licence from the US manufacturer Strandex which is especially dedicated to research in this field and keeps bringing innovations to the WPC manufacturing process. That is also why we are one of the highest quality composite board manufacturers in Europe.

Thanks to the investments in research and production, the European and North American companies can treat their customers to a warranty of up to 25 years. The fact that the EU manufactured products must also meet strict environmental regulations is yet another important factor.

How to distinguish good quality WPC from poor quality WPC?

HIGH QUALITY COMPOUND MIXTURE

Common composite material composition

60 % wood
The hardness and/or origin of the wood have no effect on the quality. In America, the boards are manufactured even from rice, grain or paper. What matters the most is the length and thickness of the fibre.

30 % plastic
Several types of plastic are used, each one of them with different features. The cheaper plastics (such as polypropylene) get brittle in freezing temperatures, whereas HDPE and PVC are the best quality materials for the making of wood-plastic.

Quality products contain about 10 % of silicone, UV stabilizers, colouring agents and adhesives.
Although it is only a small proportion, it is the most important and expensive item. In addition, each company has its own production method and proportion of ingredients – and these few per cent become a protected know-how. If the company decided to save on costs of any of these items, the boards would disintegrate and the material would deteriorate in a short time.

Architect's Tip

Terafest® can bend to your expectations

As opposed to the WPC materials which contain, for instance, PVC, the Terafest® boards can be bent by heat. This proves to be a great advantage, for example, for pool decks which are circular or drop-shaped. At the same time, they are minimally absorbent and they are resistant to pool chemicals and salt water. High quality boards feature a special non-slip surface which does not form splinters. Their profile is full so they do not warp or crack and are easy and quick to install.

Matures like wood, but doesn't turn grey

Colour maturation of the material

The Terafest composite material is characterised by its colour stability. Over the years, the colours and surface texture change slightly, but the original colour character remains unchanged throughout its entire service life. This colour maturation which is most intense in the first months after installation, gives the deckings their natural look and patina.

The Terafest composite wood contains a high percentage of wood which – being a natural material – reacts to sun and water. Lignin and tannin are gradually expelled to the surface of the boards, causing them to gradually turn grey. At the beginning of this process, the board surface acquires a slightly yellowish tinge, but this fades relatively quickly.

The speed of this process depends on the sunshine and rainfall intensity. The homogeneity across the decking is determined by its orientation and/or by how it is covered by roof or furniture. For this reason, we recommend not leaving any garden furniture, flowerpots, parasols, barbecues and other accessories on the decking for the first couple of month, but moving them around constantly. For covered deckings, it is advisable to replace the rain effects with more frequent washing with water.

The time of maturation is about 3 to 6 months for an open decking and one year for a covered one. After this period, the board surface acquires a final shade which no longer changes, unless it is mechanically damaged.

How to choose a quality manufacturer

The best and easier way of finding out about the product quality is reading the history of the company and verifying the origin of the boards. The company with many years of manufacturing experience and/or valid license from a well-known and experienced manufacturer should be a sufficient guarantee of quality. There are several companies on the European market which meet these parameters and the guarantees they present are built on a quality basis. All their products have passed the tests and their deckings are highly popular.
