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.

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 |

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).
