Ventilated facades- Description
The ventilated facade is a system of construction, consolidated over time and appreciated in north European countries; only in recent decades is it being increasingly adopted in Italy thanks to its advantages of energy-saving. The system is formed, from interior to exterior, by an insulating layer anchored to the supporting structure, and by a layer of cladding tied to the building through means of an appropriate fixing system. Between insulator and cladding an air space is thus created which, due to the "stack effect", creates effective natural ventilation, with notable benefits for the entire system.
Compared with cladding applied directly to the wall structure, the advantages of a ventilated facade are:
1. reduced risk of cracking and detachment;
2. easy installation; elements are assembled "dry" on site without the use of adhesives, by means of mechanical-type fitting and anchoring devices.
3. maintenance: work may be done separately on each individual slab
4. protection of the wall structure against atmospheric agents;
5. energy-saving;
6. elimination of cold bridges;
7. elimination of surface condensation (the presence of an air space helps expel water vapour from inside, reducing dampness caused by infiltrations).
