No adhesive, just nails
It doesn’t just look good, it’s quick to lay too: By attaching directly to the integrated click-bar, the R.16 roof plate makes the tinsmith’s life a lot easier. It also allows for completely new approaches to roof design. With its large size, boasting a component length of 70 cm and width of 42 cm, roofs can be covered using just 3.4 R.16 roof tiles per square metre, whilst at the same time giving the whole thing an elegant shine.
The R.16 roof tile can be used from a minimum pitch of 17°. With a weight of just 2.5 kg/m², this creates a truly lightweight roof that is also stormproof and even rust-proof thanks to the aluminium.

Expert tip
:
The noise-insulating strips make the PREFA R.16 roof tile quieter
Aluminium roofs are quieter than their reputation would have you believe. Everyone perceives noise differently. The PREFA R.16 roof tile has noise-insulating strips (FD.TEC) to keep noise levels to a minimum. For even more comfort in residential buildings, we recommend additionally using a thicker separation layer.

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.

Still got questions about PREFA roof tiles?: FAQs
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 tiles, shingle, roof panels, rhomboid 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.
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!
Small hailstones will not do anything to a PREFA roof with a stucco surface. As is the case with all roofing materials, it is not possible to exclude the possibility of functional damage to the roof in the event of a hailstorm with very large hailstones. However, it is possible to exclude with absolute certainty the possibility of PREFA roofing being penetrated, even during the most extreme hailstorms.

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 fastening, 3 PREFA ring nails per R.16 roof tile (i.e. 10 PREFA ring nails per m²) |
Roof structure
PREFA aluminium roofs are produced with a ventilated sub-structure, with the roof cover and thermal insulation layer separated by a ventilated gap. This means any occasional condensation, for example, can be wicked away.
It is mostly the roof membrane that is ventilated, as shown in the first picture. However, the entire attic can be ventilated too (image on right).
