Installing the storm-proof clip

The spacing between the storm-proof clip and siding tongue is decisive for tension-free installation and material expansion. For this reason, install the storm-proof clip exclusive with the appropriate installation aid to ensure consistent spacing.

The storm-proof clip must be installed on all fastening points with the following combination of material thickness and width (each siding must be fastened on at least two substructure profiles).

Note

For perforated siding, the supporting sub-structure and the fastening strip, including storm-proof clips, are visible through the perforation.

The storm-proof clip is screwed into the fastening strip (spring) and holds the overlapping siding in place:

Note

If you start off the façade with a 400 × 1.2 mm siding, for example, you must fasten the storm-proof clip to the starter profile.

Insert PREFA storm-proof clip accordingly into the PREFA installation aid (Image 1).
Then place the PREFA installation aid with the inserted storm-proof clip on the fastening strap and align it laterally. The hole on the back of the clip must be centered over the elongated hole in the siding (Image 2).

Push the PREFA installation aid with the storm-proof clip into the fastening strap (Image 3).
The storm-proof clip is then attached to the substructure (Fig. 4).

Ensure that the installation aid is positioned in the centre of the elongated hole. The side flaps on the installation aid assist in finding the right position in the centre of the elongated hole (Fig. 5).
The PREFA installation aid can now be removed from the fastening strap. This creates the required spacing for further installation (Image 6).

Next install the PREFA siding in accordance with installation guidelines, which is held in place by the storm-proof clip (Image 7).
