Ventilated rainscreen

Ventilated rainscreens

For a ventilated rainscreen, the cladding will not be applied directly onto the masonry, but mounted onto a substructure. Thus, insulation (moisture, thermal, sound and fire protecions) and weather protection are construc­tionally seperated. This method creates a ventilation space between the components, which regulates the moisture balance within the building structure.

Today's ventilated rainscreens are amongst the most successful façade systems. Current studies of the façade market verify that, besides its functional safety, architects most highly appreciate the creative possibilities of a ventilated rainscreen.

The system of the ventilated rainscreen allows for a choice of the most different claddings. Therefore, the design of the façade can be individually matched to the characteristics of a building. Even combinations of different materials can be easily implemented – by the use of different cladding materials.

Longevity and efficiency

Due to their long lifetime and the low maintenance and repair costs, ventilated rainscreens prove a very efficient and sustainable investment. Furthermore, the constructional seperation of the functions of thermal and weather protection makes it less damage prone than other façade systems.

Design variety and building culture

A wide range of materials is available for the cladding of a ventilated rainscreen. Durability, light fastness and frost-resistance of these materials are the basic requirements for the increasingly demanded longevity of the façade. Proven materials are ceramics, porcelain stoneware, natural stone, HPL and fibre-enforced resin composite panels, fibre cement panels etc.


The substructure is the statical connection between the exterior bearing wall and the façade cladding. Substructures are three-dimensionally adjustable and lie tension-free around the building structure. Uneven surfaces and wall projections can be counterbalanced and special requirements concerning fire protection, sound insulation or lightning protection can be implemented without any problems and in a creatively appealing way.

Climate control

Within the system of the ventilated rainscreen, the components of insulation (thermal insulation, cold insulation and fire protection) and cladding (weather protection) are construc­tionally seperated. The use of mineral insulation materials with heat conductivity groups 035 or 032 is a frequent practice with ventilated rainscreens on buildings of any height or use. The requirements of the current energy saving regulations are fulfilled, as the system allows for the incorporation of any required insulaton. The ventilation space between the components regulates the moisture balance within the building structure. Building moisture and moisture due to occupancy are discharged reliably through this ventilation space. Moist external walls will desiccate within a short period of time, permanently ensuring the optimum indoor climate.

KEIL and TILE EZE are both founding members of the new rain screen association in the USA.

The FVHF is the lobby of the manufacturers of claddings, substructures  and thermal insulation materials as well as anchoring, connecting and fixing elements for ventilated rainscreens (VHF).
