Clever design meets technical ingenuity! The PREFA FX.12 roof panel is a unique roof element that creates a particularly futuristic surface design due to its geometric designs. Depending on sunlight, the irregular edges create vibrant light and shadow effects.

In addition to their appearance, the edges have an essential function: they reinforce the panels, thus ensuring even greater resistance. Another special feature is the tapered standing seam, which serves to absorb the resulting lateral expansion.

In addition to its individual look, FX.12 also offers many practical advantages in processing – and thus meets all the requirements of both the modern and the traditional tinsmith craft. FX.12 is extremely quick to install due to its direct mounting on the integrated fastening strip. Furthermore, due to their large format, only a few panels are needed to cover 1 m² of roof surface.

The PREFA roof panel FX.12 is fastened with nails to the substructure by means of a fastening strip on the product.

Expert tip: The noise-insulating strip makes the PREFA FX.12 roof panel quieter.

Aluminium roofs are quieter than their reputation would have you believe. Everyone perceives noise differently. The PREFA FX.12 roof panel has a noise-insulating strip (FD.TEC) to keep noise levels to a minimum.

Colour range of the PREFA FX.12 roof panel

The colour palette of the PREFA FX.12 roof panel ranges from classic brick red via modern shades of grey up to brown tones. The following PREFA roof colours are available as standard:

Notes

  • The RAL values stated are merely approximate values (~), some of which may differ vastly from the original PREFA color and, under certain circumstances, may not reflect the subjective perception of the color. 
  • Above all for color quality P.10, it is almost impossible to define values due to the surface structure. In addition, the PREFA Siding colours P.10 stone grey, P.10 sand brown, P.10 patina green, natural oak, patina grey, walnut and grey oak are based on natural colours made up of several different shades.
  • Coils and metal sheets plain aluminium: The guarantee does not cover surface appearance alterations caused by processing and environmental influences. Follow the instructions.
  • Metallic colors may vary in shade.
  • To identify exact colors for complementary components please consult original samples.

Be inspired by reference properties that have already been implemented.

Not only the irregular edges and the resulting lighting effects ensure a visual highlight. Two different panel formats (short and long) also enable the appearance of the roof to be further shaped. We have developed three laying examples for the FX.12 roof panel for you – of course, other variants are also possible.

Whether you’re re-laying your roof from scratch or renovating your old roof, you’ll find some inspiring projects here:

The Reuti hotel and Käserstatt mountain restaurant were constructed with lots of wood and stone. For the Managing Director of Bergbahnen Meiringen-Hasliberg, Hanspeter Wenger, these two new buildings in the region are particularly important, and he commissioned the architectural firm Amstutz Abplanalp Birri from Meiringen and the architect Jost Zumstein for this purpose. The high-quality PREFA products can withstand these conditions and protect the building from damage.

At Käserstatt, at 1850 metres above sea level, the snow is sometimes up to three metres deep and the winds can be up to 150 kilometres per hour.

Technical information

Material

coil-coated aluminium, 0.7 mm thick

Dimensions

700×420 mm (cover), i.e. 3.4 pc./m²
1,400×420 mm (cover), i.e. 1.7 pc./m²

Weight

approx. 2.4–2.5 kg/m²

Minimum roof pitch

17° (approx. 31%)

Supporting substrate and separation layer*

On fully boarded substrate (at least 24 mm), a separation layer is required for roof pitches between 17° and 25°; with snow loads greater than 3.25 kN/m² or in terrain categories 0, I or II, fully boarded substrate with a separation layer is required.

* Observe country-specific standards and specialist guidelines.

Standard fastening

direct, with 3 PREFA ring nails per small FX.12 roof panel, with 5 PREFA ring nails per large FX.12 roof panel (i.e. 8–10 PREFA ring nails per m²)

* Observe country-specific standards and specialist guidelines.

PREFA aluminium roofs are preferably executed with a vetilated build up, whre the substrate and thermal insulation layer is separated by a ventilated gap. This means any occasional condensation can be wicked away.

It is mostly the roof membrane that is ventilated, as shown in the first picture. However, the whole attic space can also be ventilated (second picture).
