The ventilated faade or trasventilada is a building envelope system composed of an inner sheet, an insulating layer, and an outer sheet unsealed. The system is anchored on the facade of the building (constituting the inner sheet) metal aluminum or steel substructure that supports the outer sheet (finishing up the building). between the front and finishing a layer of insulating material is placed and an air chamber which enables air flow continuously and help reduce Portada Web thermal losses of the building.
The materials used for finishing is varied: ceramics, stone, wood, sandwich panels, all of them highly resistant to thermal inclement so it guarantees a good appearance of the facade for a long time. Regarding the insulation materials that are usually used most frequently they are: polyurethane foam plates of expanded polystyrene (EPS) and extruded (XPS), glass wool and mineral wool (rockwool), plates of agglomerated cork and cellulose and cellulose projected.
The ventilated facade system provides energy savings of between 70 and 75 in energy consumption. Advantages of ventilated facades: wide variety of durable finishes and high quality, excellent thermal and acoustic performance, reducing thermal jumps, removing dampness, perfect adaptation to structural support and low maintenance costs. Conversely economic cost of this type of insulation is superior to other systems and there is a risk of detachment of the finished plates.
