Ventilated facade: technology for comfort and sustainability
One of the constructive technologies we have frequently adopted in our projects is the ventilated façade, a constructive system that, besides presenting itself as a great aesthetic solution for the facades, brings numerous benefits to the building and its users - such as comfort environmental, durability and low maintenance.
The ventilated facade is an external coating - which can be various materials such as ceramic, fiber cement, metal, porcelain, stone, etc. - Applied away from the closing walls by means of an aluminum substructure and semi-rigid thermal insulation plates. This "second skin" of the building
forms a space between isolation and external coating, providing a natural ventilation by “chimney effect” (when there is room for air inlet at the bottom and air outlet at the top of the facade).
Environmental comfort is one of the main benefits provided by technology. In summer, the system reduces thermal variation, as the sun is directly on the coating and not on the closing wall; In addition, the heated air between the layers ascends by convection and gives way to the fresher air, reducing heat propagation into the building. In winter, technology gives thermal stability to the building, as the facade system acts as a heat accumulator; In addition, the thermal insulation layer applied to the outer wall reduces the speed of heat loss from the internal environment. These solutions directly contribute to the substantial reduction of air conditioning energy expenses.
Another great benefit of the system is durability : Open joints of coating plates allow free expansion/retraction of parts, avoiding pathologies by thermal variations; In addition, the material comes from the factory pigmented, which does not require future façade re-pincture and reduces maintenance costs. Because it is removed from the sealing walls, the system also confers tightness to the façade - the water that enters the air chamber drips through the coating itself, protecting the inner wall of the rainwater.
System installation occurs as an assembly line: the profiles and plates are cut and fitted, providing agility and assertiveness in execution, and less waste in the construction site.
This was the technology used on the main facades of Praça4, our project for the famcorp developers and places with soul in the Menino Deus neighborhood, which is in its final phase of construction. Check out some photos of the system installation on the work:
