Cavity is the space immediately behind the cladding of a wall. It allows for drainage, which is key for managing water in and around the building. Cavity space is important to the construction of buildings as it allows for ventilation between the external and internal walls. Construction cavity is particularly important for managing water in and around buildings. In more recent times the cavity has been a space which has been used to add additional insulation to a building, this being particularly important nowadays as it is noted in the regulations for new builds that a property has to have an efficient energy rating.
