Advantages of clip fixation in general:

  • Ease of installation: The clip fastening is easy to install, as you simply slide the clips between the wooden boards and attach them to the structure below. This avoids having to drill holes in the wooden slats, which can damage them and reduce their lifespan.
  • Clean Appearance: Clips (depending on systems) are invisible, giving your deck a clean, crisp finish.

Disadvantages of clip fastening in general:

wood Wakeup call !!

Wood is a natural material that is subject to movement due to the absorption and release of moisture. When it is humid, the wood can absorb moisture from the surrounding air and expand. Conversely, when it is dry, wood can release moisture and shrink. This movement can cause cracks, splits and warping of the wood planks. It is important to consider these natural movements when designing and building a wood deck, and to use proper fastening methods to allow the wood to expand and contract without being damaged. Thanks to the clip in technical composite material, the Softline clips are both able to hold the board well but also to allow it to vary dimensionally in width. This technical prowess allows the board to limit the phenomenon of curling and/or camber.

Some types of wood are better suited for fixing with clips!

Wood flooring that uses screws restricts the wood’s natural movement by holding it firmly in place. This may seem like an effective solution to prevent warping and cracking, but in reality it can cause more damage to the wood in the long run.

The screws prevent the wood from freely expanding and contracting, which can cause internal tension in the wood slats. Over time, this tension can lead to cracks, tears and warping of the wood. In addition, the screws can sag or deform under the effect of tension, which can make the terrace unstable and dangerous in use.
