Spacers for decking boards

Spacers for joints

Every outdoor wooden deck needs gaps between the decking boards to allow the wood to work and rainwater to drain away. Spacers should be used to ensure that the joint spacing is even across the entire terrace. Even during terrace construction, these prevent the gaps between the joints from being of different widths.

Two construction methods

There are two types of spacers:

• permanently installed spacers, such as the Spacer Terrafix or Spacers BioMaderas
• freely movable spacers, such as the Spacers for decking boards

Fixed spacers

The permanently installed spacers are fixed between the substructure and the decking boards when the deck is installed. This not only creates a gap between the decking boards, but also between the substructure and the decking board, which ensures better ventilation of the terrace. The disadvantage of these terrace joint holders is that the requirement per square meter is significantly higher than with freely movable models. In addition, the spacers are not suitable for systems of concealed terrace screwing.

Movable spacers

Freely movable spacers are placed between the already screwed and the still to be screwed terrace boards when assembling the wooden terrace. It is best to always place a decking joint holder at the intersection of decking boards and substructure. After screwing, the spacers can be removed again and used for the next row of planks. Therefore, the need is significantly lower than with the permanently installed spacers. However, for optimal constructive wood protection, a distance profile should be used.
