ESSENTIAL - Because an environmentally-friendly road also means more natural road restraint systems
The concept is based on the exclusive use of Douglas heartwood, which is naturally resistant to attack by wood-eating insects and rot-proof.
This characteristic enables the wood to meet the requirements of use classes 3.1 and 3.2 according to standard NF EN335.
By choosing Douglas fir for its products, Tertu guarantees exceptional durability and quality, while offering environmentally-friendly solutions.
THE HEART OF DOUGLAS WOOD IS :
RESISTANCE TO FUNGAL
fungal and insect attacks
NATURALLY
sustainable
REFRACTAIRE
to moisture absorption
Advantages of the ESSENTIEL concept
Untreated: No chemical agents are used in the treatment process, which avoids any discharge into the soil through drainage.
Authentic colour: The wood retains its vivid Douglas fir colour, which naturally greys over time, giving it an authentic, natural look.
Technical performance: Devices designed according to the ‘Essentiel’ concept maintain the same performance as crash-tested models, guaranteeing user safety.
Ultra-durability: The wood used in the ‘Essentiel’ concept comes with a 10-year NovaVita guarantee, ensuring its durability and resistance over time.
Recyclable: Products designed according to this concept are fully recyclable, which helps to reduce their environmental impact at the end of their useful life.
Reduced embodied energy: The manufacturing process for ‘Essentiel’ products reduces embodied energy, notably because no drying is required and the untreated wood is not subjected to autoclave treatment, which contributes to a reduced environmental footprint.
