Fixing types: Visible and invisible terrace fixings

Each type of terrace fixing has its advantages. Here is a summary of the various fixing options available.

Visible terrace fixing systems

The innovative screws from SIHGA® for visible terrace fixing reduce splitting and cracking in almost all wooden decking boards. The newly developed product Alu-TeFix® is available in two versions - made of hardened, rust-free stainless steel and in A2 quality. Pre-drilling or pre-sinking is not necessary. This makes assembly much easier and faster.

  • time-saving
  • simple installation
  • low-cost procurement
  • reduced splitting and cracking

Invisible terrace fixing

With the SenoFix® FT screw and connector system, decking boards can be screwed together invisibly. The aim of the invisible terrace fixing is to ensure a beautiful appearance as well as a long service life of the terrace. The decking boards are screwed into the joint or from below, which means that no screws are visible on the top of the boards. This considerably prolongs the durability of the terrace and reduces rotting due to weathering. The invisible decking fixing also provides better support, but still allows the decking boards to work naturally without the fixing warping or coming loose.

Fixing for the terrace substructure

Timber is being used more and more frequently in terrace construction due to its excellent properties. As a specialist in timber construction, SIHGA® therefore presents innovative rail systems with which wooden decking boards can be easily installed. SIHGA® is offering a new development in the area of terrace substructures, among other things, with the TefaFix® T rail system. The system, which was developed for fixing wooden boards, offers a firm grip, efficient water drainage and good ventilation of the entire terrace.

Terrace fixing with structural wood protection

Outdoor terraces are permanently exposed to the elements. Structural wood protection is therefore an indispensable measure to prevent rot, fungus and algae infestation. With TerrassenFix Air® and TerrassenFix Aqua® SIHGA® offers two aluminium profiles as a drainage grid and ventilation element. This will prevent the wood of the terrace from weathering, ensure sufficient ventilation and allow good water drainage.

Frequently asked questions about terrace fixings:

The type of terrace fixing has a major influence on the terrace's appearance and significantly affects the overall appearance of the outdoor area. The various terrace fixing systems from SIHGA® offer a wide range of advantages. The invisible fixing, for example, scores with its clear and modern lines and blends inconspicuously into its surroundings. It is therefore advisable to choose the type of fixing carefully when building a terrace to ensure that it fits harmoniously into the outdoor area.

When installing decking boards, there is the option of concealed or visible screw fixings. The visible screw connection is the traditional method and requires less time during assembly. Here, the boards are simply fixed to the substructure with screws, and the screw heads remain visible. With special systems from SIHGA®, however, the terrace can also be fixed invisibly. This offers the advantage that the screws are protected from the weather, thus extending the life of the terrace.

One essential factor when using timber outdoors is structural wood protection. Especially with decking boards, always make sure that a spacer is used between the boards and the substructure. This provides adequate ventilation and allows moisture to dry off quickly.

It is crucial to maintain the correct spacing between decking boards as wood has a tendency to shrink and expand due to the absorption and release of water. For this reason, there should be a minimum distance of 4-5 millimetres between the boards, even in damp conditions.
