Maintaining the façade: Rear ventilated façade offers a long service life


The rear ventilated façade

The name "curtain ventilated facade" (VHF) describes the structure of the facade cladding: An air layer separates the outermost facade cladding from the underlying insulating layer. This is how the ventilated façade protects and insulates the masonry from the effects of the weather. The materials used must be frost resistant and lightfast, i. that even strong sunlight does not change the hue. For this, panels made of wood cement, fiber cement or highly compacted rock wool, ceramic and porcelain stoneware, bricks or fiber-reinforced resin composite panels have proven to be suitable.

Good for building and indoor climate

The air can circulate through the cavity between the facade and the insulation. This regulates the moisture and reliably dissolves moisture from building and use. This has two advantages: Construction and insulation remain dry and the interior climate is regulated. Because moist outdoor spaces dry out within a very short time. By separating heat and weather protection, any insulation thickness can be realized. This creates a comfortable room climate and also saves energy.

The requirements of an energy-saving façade are met.

Pre-ventilated facades are predominantly made of mineral insulating materials that easily meet the required requirements of the Energy Saving Ordinance. This also applies to the thickness of the insulation, which can even be increased later on in ventilated facades.

Looks good, insulates well and lasts a long time

Ventilated facades are not only practical and efficient, they can also look good. There is something for every taste: In addition to façade cladding such as wooden shingles, metal sheets, natural stone or frosted glass, it is also possible to realize very unusual clothing such as a media façade, photovoltaic elements or greenery. The comparatively high price is compensated by the long service life of more than 50 years. For example, the ventilated curtain wall is a sustainable and efficient solution for giving your home an attractive and resistant second skin.
