The numerous design possibilities of PREFALZ are impressive. With different panel widths and lengths and different installationdirections as well as the extensive colour range, you can design your standing seam façade entirely according to your ideas. PREFALZ offers  a wide range of creative applicationsfor wall (single lock seam) or roof (double lock seam) applications. Thanks to the material aluminium, it is more pliablethan most comparable seam materials and therefore particularly easy to work with, plus it is rust-proof even after decades.

The pliability of the material does not affect the quality of the lacquer. PREFALZ façades and roofs score points for stability and durability and last throughout the life of a house.

Rainproof joints can be easily achieved thanks to the concealed, invisible fastening. With its low weight of between 2.2 and 2.3 kg/m², depending on the tray width, PREFALZ isideal for both refurbishments and also new builds.Rainproof joints can be easily achieved thanks to the concealed, invisible fastening.

It should be particularly emphasised that the PREFALZ façade made of aluminium complies with reaction to fire classification "A1" - i.e. non-combustible - according to EN 13501-1. You can find more information on fire protection here.

PREFALZ combines flexibility, elegance and infinite design possibilities. Like all our PREFA façades, the aluminium angled standing seam façade is also designed as a rear-ventilated façade

Seaming details

The angled standing seam is mainly used for façade cladding. This is an alternative to double lock seam but without closing the seam completely.

Installation systems and application types

In the case of strip covering, the PREFALZ strips, also known as panels, are produced on roll formers from strip sheets.

These metal sheets can beinstalled using longsliding clips up to a length of 12m. The long sheets allow an easy, safe and economical installation of the roof covering.

For panel roofing or mirror roofing, shorter PREFALZ sheets are cut to size, which are connected by staggered cross welts Façade surfaces can be structured better in this way.

Let yourself be inspired by already implemented projects with PREFALZ façade

PREFALZ can be used to clad the entire building envelope, i.e. façade and roof as well as trimmings, giving it the appearance of being cast from a single mould. Give your façade an individual touch by varying the width of the panels or using conical panels. You can incorporate your own individual preferences by using different installation directions (horizontal, vertical or diagonal). Use PREFALZ as a façade system for modern new buildings or extensions with a flat roof as a parapetcappings

Notes

  • The RAL 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.
  • Plain aluminium: The guarantee does not cover surface appearance alterations caused by processing and environmental influences. Follow the instructions.
  • Metallic colours may vary in shade.
  • To identify exact colours for complementary components please consult original samples.

PREFALZ technical information

Material

coil-coated aluminium, 0.7 mm thick

Standard dimensions

PREFALZ for façades: 0.7×500 mm
complementary coil: 0.7×1,000 mm

Weight

approx. 1.89 kg/m²
actual consumption with PREFALZ 500: approx. 2.3 kg/m²

Supporting substrate and separation layer*

on fully boarded substrate (at least 24 mm)

* Observe country-specific standards and specialist guidelines.

Fastening

PREFA preformed fixed and long sliding clips (stainless steel) according to static requirements

Caution: Mixing PREFALZ coils with colour coatedaluminium   fromcompetitive manufacturers, but also with FALZONAL material of supposedly the same colour, should be avoided at all costs because of the different paint qualities and subsequent differences in the weathering. Only in this way can you enjoy a harmonious-looking façade even after many years. This must also be observed for weatherings, cappings and the like.

Do you have any questions about the PREFALZ façade?

Fears of rusting are completely unfounded because aluminium cannot rust. If the surface of the PREFA aluminium façade is damaged, a new protective oxide layer is formed and the durability of the PREFA façade remains unchanged.

Non-bearing, rear-ventilated façades are designed to prevent moisture from forming. By separating the insulation and façade cladding, there is a constant air flow in the rear-ventilated space which regulates the moisture balance and ensures dryness. Thanks to the permanent ventilation, professional installation will not result in mould formation underneath the façade.
