Use of ventilated envelopes in building retrofitting.

The application of a continuous thermal insulation on the external face of building walls ameliorates the thermal performance of external walls and alleviates problems related to thermal bridges. However a further improvement of this insulation system may be achieved by using ventilated walls, which consist of an open ended cavity placed between an insulating board {directly applied on the external side of outer walls) and an external cladding.
