With the unique, concealed fastenings and the special laying technique with offset joints, your PREFA aluminium roof and PREFA façade are able to withstand even high wind speeds. The number of fasteners can be increased depending on the wind load, and the type of fastening (nailed or screwed) can be adapted accordingly.

Aluminium forms a protective layer which constantly self-regenerates to protect itself from damage. In addition, on most PREFA roofs and façades, the material is given a high-quality coil-coating finish.

At just 2.6 kg/m², a PREFA roof weighs only a fraction of a conventional roof (approx. 35–55 kg/m²). Therefore, the weight on the roof structure of a typical detached house is reduced by up to ten tonnes! The light weight of aluminium also has a positive influence on transport and construction site times.

Not even heavy snow loads, extreme temperature fluctuations or bad weather conditions pose a problem for PREFA aluminium roofs and façades. Aluminium’s particularly good properties and resistance are the reason for this.

PREFA offers infinite design possibilities. Choose from a variety of shapes, formats, colours, installation patterns and surfaces. In the complete system, each product, including accessories, can be perfectly colour-coordinated. Even bespoke colours are available on request in the required quantities.

Thanks to a special coating layer, PREFA product surfaces are highly resistant to temperature and weathering. The reason for this is the coil-coating system which is applied in up to 20 processing steps.

In the case of roof renovations, due to structural engineering reasons, old roof structures often have to be prepared so that they can cope with the extremely heavy load that they are subjected to by modern roof tiles. However, with the much lighter PREFA aluminium roof, there’s no need to make any additional reinforcements.

Not only is PREFA the strong roof specialist, it also produces high-quality products for façades, roof drainage systems, flood protection and solar panel substructures—tested and coordinated system components for the outer building shell—exclusively installed by trained specialist companies.

Aluminium can be recycled as often as necessary without loss of quality — and the best thing about it: PREFA products already consist of up to 87% recycled aluminium. In addition, 100% of the electrical power used at the Marktl production site comes from renewable energy. Furthermore, 99% of the aluminium production waste is returned to the starting point.

PREFA provides up to 40-year colour and material guarantee on PREFA roofs and façades. This provides you with optimum protection against breakage, corrosion (rust), frost damage, chips and blistering.
