2.1.4 Installation of a ventilated façade

2.1.4 Installation of a ventilated façade

Description

It is a double façade system provided with an external coating fastened with metal profiles to the internal part of the enclosure. Between both, there is an air chamber partially filled in with thermal insulation. The ventilation is raised through top and bottom openings or through the design of the envelope seals.

Benefits

  • Protection of the internal enclosure and of the insulation against the action of the wind, the rain and solar radiation.

  • Elimination of thermal bridges

  • Decrease of the solar contribution in summer conditions

  • Thermal inertia

  • Ease of assembly

  • Easy maintenance

  • Valid solution for retrofitting of buildings without discomfort for occupants and without affecting its useful surfaces.

Limitations

  • More complex installation than other systems

  • Bad fire resistance

Economic assessment

Initial investment: high. About 164 €/m2. Higher costs than the other interventions of facade insulation and the maintenance and cost replacement must be realistic and amortizable for the ownership of the building
