Terrace system Character Massive /

Ideal for pool sides and curved shapes

The Character Massive system provides maximum flexibility and adaptability. At the same time, the solid boards are extremely robust and durable. Unlike other Twinson boards, the solid boards have no cavities. The advantage of this is that the boards are as easy to cut to size accurately as wood, but thanks to the innovative wood-plastic composite they are highly robust, durable and easy to maintain. Solid boards are therefore particularly suitable for curved shapes and heavily used areas by the pool.

Construct your terrace with curves!

Round edges can be cut very easily and precisely with Character Massive.
A special rotatable clip has been developed for laying organic shapes. The clip makes it easy to fix the planks to the substructure even if it is not at right angles. This means that there's no longer anything standing in the way of free laying of the type needed around pool sides, garden paths or flower beds. And best of all: Both sides of the massive plank can be used. One surface is finely grooved, the other side has a smooth texture. No other Inoutic product has this wood grain texture.

The innovative click system is used as a stable substructure for Twinson terraces. Twinson Click is a screwless, efficient, modular and durable system, which is completely recyclable. Consequently, Twinson terraces can be installed much faster and easier. And the more complicated the shape of the terrace, the more time is saved.

Your terrace says thanks to nature

Twinson terraces save natural resources, they are environmentally friendly and a true alternative to tropical hardwood. Our Twinson products made by an innovative wood-PVC composite all carry the PEFC seal. This guarantees that the wood originates from sustainable forestry and that the forest's biodiversity is preserved.

In addition, for the first time, Twinson decking WPC boards have been awarded the VinylPlus certificate. The VinylPlus® product label is a labelling system that facilitates the identification of the most sustainable and best performing PVC products.

Moreover, the plastic content in Twinson decking is completely made of recycled PVC. In order to preserve the resource-saving PVC for the eco-core, old plastic windows are first roughly shredded and materials such as glass are sorted out in the recycling plant of the Deceuninck Group in Belgium. The coarse material is then cleaned, processed and regranulated. These granules are used, for the core of the decking. According to VinylPlus, 2 kg of CO2 emissions are saved per kg of recycled PVC. In addition, the short intra-European transport routes reduce CO2 emissions. We make an important contribution to environmental protection.

All products are 100 % recyclable at the end of their service life.

Character Massive

From linear designs to playful geometric shapes – with two different surfaces the Twinson Character Massive terrace system accommodates all wishes and requirements. At the same time, these solid 
floorboards are extremely resilient, durable and easy to clean, given that they do not have any hollow chambers unlike other floorboards and therefore, the floorboards can be cut as easily and accurately as wood. Character Massive is therefore ideal for pool borders and curved shapes.
