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
