Frequently Asked Questions
Frequently asked questions
Everything about
this product
What is the difference between a single-sided and a double-sided composite decking board?
A double-sided composite decking board is reversible: both faces are finished and usable. That gives flexibility at installation and lets you turn the board over if one face wears, doubling its useful life compared with a single-sided board.
Why choose composite wood for an outdoor terrace rather than natural timber?
Composite wood gives the look of timber with none of its upkeep — no stain, no sanding, no treatment. It does not split, does not grey and resists UV, moisture and insects, unlike natural timber, which needs regular and costly maintenance.
What does a composite terrace cost per m² ?
The price of a composite terrace varies with the quality and the dimensions of the boards chosen. For a premium composite terrace such as the DECNO Walnut-G boards, contact us through our quote form to get a price tailored to the area of your project.
Does the Walnut-G composite board stand up to high heat in Morocco?
Yes. WPC composite resists UV and high temperatures, which makes it the right choice for sun-exposed terraces, particularly in hot climates such as Morocco. The Walnut-G shade carries built-in UV protection.
How do you install a 3100 × 140 × 22 composite decking board?
The board is laid on joists spaced 40 to 60 cm apart, fixed with stainless screws or a clip system. Allow a 5 mm expansion gap between boards and 10 mm at the ends. The 3100 mm length covers large areas while limiting cuts.
Does a composite terrace need maintenance?
No. A composite deck needs no particular upkeep. Simply washing with soapy water once or twice a year is enough to preserve the look and the properties of your Walnut-G double-sided composite boards.
