Ventilated Facade

A protective layer to your building.

History

HISTORY

The idea of a ventilated facade derives from the cavity wall, which became a common building structure in the late 19th century. Cavity walls were cheaper to build than their solid counterpart, offering improved thermal insulation and better weather protection.  Furthermore, expensive and more prestigeous material could be used for the thinner outer wall offering a better aesthetic finish. Air inlets in the outer wall provide ventilation and control of humidity.

A Ventilated Facade is a two-stage construction, comprising firstly, an inner load-bearing structure and secondly, the outer rainscreen and its mounting components. This outer skin protects the structure against the elements. A ventilated facade is ideal for the use in both new buildings and renovation projects. Another key feature of a Ventilated Facade is the air gap or cavity between the outer skin and the backing wall. This allows for a chimney-effect to take place, which in turn transports air through the system, ventilating the cavity, Depending on the nature of the joints between panels, a minute amount of 0.3-0.4% water penetration may occur. This  will be easily dissipated however due to the ventilation effect
