Designs, savings and comfort
Ventilated façade:
The concept of a ventilated façade refers to a constructive solution that allows the exterior of a building to be cladded.
It involves adapting the building to sustainable building, which provides a series of improvements such as: greater energy savings and a reduction in maintenance costs.
The purpose is to make buildings refurbished with ventilated façade comply with the new demands of the CTE and, with this, ensure that the owners have greater comfort and savings in the home.
How
does it work?
The ventilated façade guarantees an improvement of the thermal insulation of the building, since it allows to install continuous insulators between the external support of the supporting wall and the exterior cladding of the façade. The cladding of the ventilated façade protects the supporting structure, the thermal insulation and the substructure against the climatic influences, since it is resistant to rain.
Features
In summer
the sun shines directly on the floor and not on the building, heats the air in the chamber, decreases its density and convection rises, with fresh air taking its place. This is the phenomenon called “the chimney”, which prevents the accumulation of calories in the façade. The thermal insulation provides additional protection against atmospheric agents.
In winter
other factors come into play, since solar radiation is not enough to achieve these air movements. In this case
the façade acts as a heat accumulator with the air chamber helping the system to reach thermal stability of the system. The thermal insulator provides a
maximum thermal accumulation of the interior component that prevents the loss of heat inside the building.
Elimination of thermal bridges
Ventilated facades allow the correction of thermal bridges producing energy savings by eliminating contact between brackets and walls.
Elimination of condensations
The external bearing walls and insulation always remain dry and, therefore, fully preserve their function. The impact rain that could have been filtered through open joints will dry quickly due to the circulation of air in the ventilation space.
