Structural foundations of roof covering and information

Double-lock standing seam roofing is to be planned and executed according to structural requirements (relating to building and site).

PREFALZ solar panels 500 and 650 are designed for double-lock standing seam roofing in coil widths of 500 mm and 650 mm. If PREFA fixed clips, PREFA preformed sliding clips, PREFA preformed long sliding clips and PREFALZ solar panel clamps are used professionally in combination with PREFALZ solar panels, the thermally induced change in the length of PREFALZ
Panels is still guaranteed.

The determined tray width and the statically determined maximum spacing between clips must be taken into account during installation. In order to meet the static requirements of the solar panels clamped to the fold, the following specifications must be observed:

Maximum spacing between clips: 33 cm
The product is only to be used in combination with a PREFALZ or FALZONAL® double-lock standing seam roofing, installed on full formwork of at least 24 mm in accordance with the applicable standards and specialist guidelines, a structurally stable timber sub-structure framework and original PREFA fixing materials.
