PREFA façades are installed as non-bearing, rear-ventilated façades. This means that there is a gap for rear ventilation between the aluminium façade cladding and the insulation. In summer, the hot air cannot accumulate behind the façade because it rises through the rear ventilation and is transported away. In the winter, this structure provides thermal protection, as the heat transfer resistance is increased in the rear-ventilated space. This temperature buffering in the rear-ventilated space ensures a comfortable indoor climate all year round.

The PREFA façade is the outermost protective layer of your house and simultaneously serves as a visual design element to improve the look of your home. Not only is it nice to look at, it also protects your home from the weather. In addition, durable PREFA aluminium cladding protects the underlying layers (supporting structure, insulation and substructure) from the effects of the weather. Owing to the fact that your PREFA façade is particularly weather-resistant, you can enjoy its beautiful appearance for decades.

It should be noted that PREFA façade products must not be confused with sandwich panels or other products with integrated insulation, as they are exclusively specialised for the functions mentioned above (protection and visual design). If you would also like to have a high-quality aluminium PREFA façade, the skilled workshop will be able to provide you with a suitable substructure and, if desired, suitable insulation in addition to improving the appearance of your home with PREFA façade cladding.

If the PREFA façade is installed properly, a perforated plate or ventilation grid will be installed at the ventilation inlet and outlet which protects against animals. As long as it is installed properly, small animals such as birds or mice will therefore be unable to damage your façade.

PREFA offers a 40-year colour and material guarantee on its products with the exceptional P.10 surface against breaking, corrosion (rust), frost damage, chipping and blistering.
