The cladding materials contained in this installation manual have been tested for their resistance to hard and soft impact stresses in accordance with the following standards or guidelines. The technical details in this document are based on these guidelines and relevant tests:
The following guidelines must be observed in addition to the PREFA installation guidelines for balcony cladding:
The frame structure and the balcony cladding must be protected against corrosion, and possible contact corrosion must also be prevented by the selected materials.
The anchoring elements used for installation (on concrete, masonry, etc.) must be dimensioned according to the local wind loads and structural safety requirements.
In the case of both new buildings and renovations, evidence must be provided on site in compliance with the applicable rules and regulations.
Only the following rivets with increased tensile breaking force that were used and confirmed in the tests are to be used for fastening PREFA balcony cladding:
The clamping range of the rivets is from 4 to 9.5 mm.
Use the corresponding rivet nosepiece for the PREFA balcony rivet in order to fasten the PREFABOND aluminium composite panels to the PREFA balcony rivet.
We recommend using a blind rivet fastener with a setting force of 10,000 N, for example, Accubird PRO from Gesipa for the installation.
Important information
Standard aluminium façade rivets are not permitted for balcony cladding, as their tensile breaking force is too low.

Note
The span of the frame structure must be structurally checked in terms of the loads acting on it.
