Roof System PREFALZ®

Name: Roof System PREFALZ®
Rating: 4 (6 reviews)

4.0(6 reviews)

Thanks to its malleability, Prefalz® is more pliable than most comparable folding materials. Planners can use it in many creative ways on roof and façade areas. Recommendation: plan a minimum substructure roof pitch of > 7º (13%). Roof pitch from 3° (according to the information/limitations of ÖNORM B 3521-1), > 7° recommended (see planning guide)

Specification

Prefalz® coils are perfect for use in standing seam roofing and cladding. Prefalz® strips are also ideal for use as flashing strips on PREFA small format components – suitable for various connections and flashings with dimensions of 0.70 × 1,000 mm (60 kg rolls).
Tip: Strong winds blowing against mono-pitched roofs with double-lock standing seams can get noisy. To tackle this problem, we recommend using Prefalz® with a strip width of 500 mm. Sufficient sound insulation measures should already be taken into account when planning the roof structure.
Caution: Combining Prefalz® strips with other colour aluminium strips should be avoided at all costs due to the different paint qualities and folding abilities.
