ROOF SYSTEMS ROOF SYSTEM PREFALZ®

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)

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 and integrating a bitumen separating layer. Sufficient sound insulation measures should already be taken into account when planning the roof structure.

Caution: Don’t try to hide damage with a coat of paint! Combining Prefalz® strips with other colour aluminium strips should be avoided at all costs due to the different paint qualities and folding abilities.

¹ The colours P.10 stone grey, P.10 sand brown, P.10 rust brown, P.10 patina green, light wood, dark wood, patina grey and natural blank reflect natural colouring and are therefore subject to minimal variation, which gives the products their unmistakable character.

² The warranty does not cover changes to the surface appearance due to processing and environmental influences. Please refer to information sheet.

³ Metallic colours may vary in shade.

Notes

• The RAL and NCS values stated are merely approximate values (~), some of which may differ vastly from the original PREFA colour and, under certain circumstances, may not reflect the subjective perception of the colour. 
• Above all for colour quality P.10, it is almost impossible to define values due to the surface structure. Furthermore, the colours P.10 stone grey, P.10 sand brown, P.10 rust brown, P.10 patina green, light wood, dark wood, and patina grey reflect natural colourings that are composed of several colour tones.
• To identify exact colours for complementary components please consult original samples.
