System Solutions for Decking Construction

WPC accessories should be selected to match the respective decking system, the substructure, and the planned assembly. Fastening systems and substructures support clean installation and must account for material-related expansion and contraction of the WPC boards.

Selecting the Right Substructure for the System

Depending on the decking system, substructures made of WPC or aluminum may be suitable. Aluminum profiles are characterized by high dimensional stability and weather resistance. Our WPC substructures are water-repellent and equipped with UV protection. Crucial factors include a load-bearing surface, sufficient ventilation, appropriate center-to-center spacing, and professional drainage.

Cleaning & Maintenance

For the cleaning and maintenance of WPC surfaces, you will find suitable cleaners and care products. Choose the respective product according to the surface and the intended application.

FAQs

For WPC decking, depending on the system, you will need suitable accessories for the substructure, fastening, finishing, and maintenance. This includes, for example, WPC clips, starter clips, substructure profiles, finishing trims, side panels, wall connections, and suitable cleaning products. It is important that the accessories and the boards are technically compatible.

WPC clips are used to fasten decking boards to the substructure. They hold the boards in position and allow for a clean, usually concealed installation. At the same time, they support uniform spacing and account for the material-related expansion of the WPC boards.

Depending on the system, WPC or aluminum substructures are suitable for WPC decking boards. Aluminum substructures offer high dimensional stability and weather resistance. The WPC substructures from Gunreben are water-repellent and equipped with UV protection. A stable foundation, sufficient ventilation, a slope, and appropriate center distances are also crucial.

Finishing trims and side panels ensure a neat edge finish for the WPC terrace. They cover open edges and give the terrace a finished, cohesive overall look. Matching profiles are particularly useful for visible end faces, steps, or wall connections.

Accessories for WPC decking are designed more for system installation, clips, finishing profiles, and the material-specific expansion of WPC. In contrast, accessories for wooden decking take into account the moisture-related swelling and shrinking of wood, different fastening methods, maintenance, and structural wood protection. Therefore, the accessories should always match the specific type of board and the system being used.
