When used in association with specific technical solutions such as ventilated facades, the mechanical properties of aluminum can provide further, great practical benefits.
First of these is its high energy performance: the ventilation effect, with the air space created between the existing wall and the new siding “skin”, greatly improves the thermal insulation parameters. This means a substantial benefit in winter, preventing heat “dispersion” to the outside which, in turn, translates into a lower heating bill. In the summer, instead, the “natural ventilation” created in the air space dissipates the heat from the produced by the sun against the aluminum siding, thus providing savings in the cost of air conditioning to keep the rooms cool.
The ventilated facades also have another important function: they protect against the weather and, more specifically, against the acid rain and photo-oxidants responsible for most damage to reinforced concrete walls. The ability to eliminate humidity even, from old buildings, is an extremely useful quality, particular when renovating old facades where the decay process derived from the infiltration of water and moisture has already set in.
The sound-proofing and resulting noise reduction provided by ventilated walls also helps insulate the building from they typical noise of the rain, wind and environmental acoustic pollution, thus improving the quality of life of those who work and live inside.
And last, but not least, maintenance is simple and inexpensive, since it only requires ordinary cleaning of the façade, its initial appearance remaining intact with the passing of time.
