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.

Makes the installer's life easier.

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 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. 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 colours may vary in shade.
  • To identify exact colours 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 tons of inspiring projects using aluminium roof panels from PREFA in our Reference Gallery and Renovation Gallery. Check out a few examples 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.

Still got questions about the PREFA FX.12 roof panel?

It would be too easy if we could offer you a total price here and now or tell you that a roof tile or façade shingle costs such and such. But unfortunately, it’s not that easy. That’s because every PREFA roof or façade needs to be carefully budgeted by one of our master roofers.

Metal roofs can be integrated into the exterior lightning protection system in accordance with the standard ÖVE/ÖNORM EN 62305-3. PREFA flat band roof panels (Prefalz and Falzonal) are therefore permitted as a natural part of the arrester and PREFA small format components (roof tilesshingleroof panelsrhomboid roof tiles) as natural components of the conductor (installation of an additional arrester and connection to the earth). Some standards stipulate exceptions according to which, for example, property at increased risk (e.g. potentially explosive premises) must be specially designed. The integration of PREFA roof and façade systems in the exterior lightning protection system must therefore be planned depending on the specifics of property in question. Information on the necessity and type of lightning protection on a property can be obtained from a lightning protection system engineer or approved electrician. Find out more about lightning protection here.

Thanks to their light weight, PREFA roof tiles, shingles and rhomboid roof tiles, FX.12 roof panels are ideal for covering existing old roofs.

Small hail stones cannot damage a PREFA roof with a stucco surface. In the case of extremely large hail stones, as with all roofing materials, functional damage cannot be excluded. However, even in an extreme hail storm, the piercing of a PREFA roof can almost certainly be ruled out.

Aluminium materials are largely corrosion-resistant and rust-free!

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)

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).
