What is a Thermal Envelope? What does the project consist of and what are the benefits?
The thermal envelope is a technique for limiting heat loss in a building through the use of insulation panels installed on the external surfaces or inside perimeter walls of the building.
The main benefit of the thermal envelope is in the reduction of winter heating and summer cooling requirements as it is creates a barrier between the inhabited spaces and the hot or cold temperatures of the external environment. But the presence of this barrier doesn’t only improve wellbeing in terms of temperature: the envelope also improves living comfort by reducing humidity and outside noise levels.
There are two types of envelope: the thermal envelope and the ventilated façade thermal envelope. The thermal envelope consists of panels installed on the perimeter walls of the building that can be plastered following their installation. The ventilated façade thermal envelope consists of insulating panels, flanked by a structure set a few centimetres away from the surface of the building. This structure supports the ceramic, metal or marble panels which, thanks to the space between them and the wall, form a layer of air that further insulates the inhabited areas.
In addition to offering improved performance of thermal insulation, the ventilated façade thermal envelope, thanks to a finish using resistant and long-lasting materials, requires an extremely low level of maintenance also in the presence of aggressive environmental conditions, such as those found in coastal or industrial locations.
Both the types of envelope bring energy benefits, the renovation of the aesthetics of the walls on which they are installed and a relative increase in the value of the property.
