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.

Fears of rusting are completely unfounded because aluminium cannot rust. If the surface of the PREFA aluminium façade is damaged, a new protective oxide layer is formed and the durability of the PREFA façade remains unchanged.

Non-bearing, rear-ventilated façades are designed to prevent moisture from forming. By separating the insulation and façade cladding, there is a constant air flow in the rear-ventilated space which regulates the moisture balance and ensures dryness. Thanks to the permanent ventilation, professional installation will not result in mould formation underneath the façade.

Aluminium wall claddings are well protected against weather conditions. Nevertheless, PREFA façades should be regularly checked and cleaned. Cleaning is uncomplicated and is not part of the 40-year material guarantee against breakage, corrosion (rust) and frost damage.
