Roof System Prefalz

PREFALZ offers numerous options in terms of colour and shape.Thanks to the aluminium material, it is more supple than most comparable folding materials and is thus particularly easy to work with. With its low weight of between 2.2 and 2.3 kg/m², depending on the tray width, PREFALZ is suitable for roof renovations as well as for new buildings, as it adapts perfectly to the different building methods. It can also be expanded with the wide range of PREFA system accessories.

From barrel roofs to complex roof extensions, domes or large-scale roofs — PREFALZ offers countless individual design options. Folds and bends won’t affect the paint quality at all: PREFALZ is supplied in numerous colours with a smooth or stucco surface, as required. PREFALZ coils can be ideally used as complementary coils for PREFA small-format products – suitable for various connections and flashings in the dimensions 0.70 × 1,000 mm (coil dimension 60 kg). It should be particularly emphasised that the PREFALZ aluminium roof complies with reaction to fire classification “A1” – thus non-combustible - according to EN 13501-1.

Fold details

In the case of standing seam coverings, pre-profiled or folded panels are folded together to create a rainproof joint. The angled standing seam is primarily used for façades, while the double standing seam is used on roof surfaces. The following two images show the cross-sections of double and angled standing seams:

STILL GOT QUESTIONS ABOUT PREFA PREFALZ roof?

PREFA roof tiles, roof shingles, rhomboid roof tiles and FX.12 roof panels are an excellent choice for covering over older existing roofs thanks to their light weight. They can be quickly mounted to the existing roofing material, such as bitumen shingles or bituminous sheeting. This type of covering requires an intact sub-structure, correct roof pitch and other basic structural requirements!

The breakdown of metals due to chemical or electrochemical reactions with their surrounding environment is called metal corrosion. The most well-known form of corrosion is the rusting of iron. Aluminium materials are largely corrosion-resistant and rust-proof!

The difference in sound between a PREFA roof and a fibre-cement or tile roof is just 2 to 4 dBA, which is barely perceptible to the human ear.

What do I need to know about fire safety? PREFA roof and façade products (small format as well as Prefalz and Sidings*) are classified as non-combustible in accordance with EN 13501-1 with fire behaviour class “A1”. Fire behaviour class A1 means that products made from aluminium are not flammable. Find out more about fire safety here.

* except products in the colours walnut, grey oak and natural oak (fire class "A2-s1, d0" - non-flammable).
