Trespa® Meteon® panels are installed as a component of rainscreen cladding or ventilated facade system. This “breathing” envelope system, employed the world over, can contribute a number of advantages to building designs.

Rainscreen and decorative facade
Trespa® Meteon® panels cut to size are used as a rainscreen and decorative facade; a building solution with both technical and aesthetic benefits. Joints between panels can remain open.

Cavity depth and ventilation
The free air cavity depth between the rainscreen cladding and the insulation or wall construction allows for ambient air to flow through from the ventilation inlets and outlets. For continuous ventilation behind the panel, a certain cavity depth between the rainscreen cladding and the insulation or wall construction is needed. The cavity depth as well as the minimum size of the ventilation inlets and outlets must be in accordance with applicable building standards, regulations and certificates.

A ventilated facade can be constructed using different tested and certified fixing systems, each with their own advantages in terms of aesthetics (e.g. invisible fixing, joinery details), installation and performance, to fix Trespa® Meteon® panels on a sub-frame.


First, a chimney effect draws air through the cavity, aiding in the removal of heat and moisture from rain or condensation. Second, the rainscreen blocks some solar gain and accommodates continuous insulation, considerably reducing air-conditioning. Third, these results are shown to improve comfort within occupied zones. Residents and users not only find themselves in a low-maintenance-environment, but the dry and comfortable conditions of the building may also make a positive contribution to indoor environmental quality
