What Does The Term Cavity Mean In Construction?
A cavity is a wall construction with a hollow space at the centre. In layman’s terms, a cavity wall can be described as two skins that have a hollow space separating them. These two skins are usually made out of cinder blocks or bricks, both of which are absorbent and draw in a considerable amount of rainwater.
The cavity between the skins helps drain this water, which can be detrimental to the integrity of the wall. Water is drained out of the cavity using weep holes at the bottom of the wall or the windows located above. The weep holes at the wall base provide a passage for the air into the cavity, which in turn takes the water to the outside environment via evaporation.
Owing to their excellent water evaporation capabilities, weep holes are also installed above wooden framed windows to prevent dry rotting of their frames. Cavity walls that have brick or cinder block construction in both their inner and outer layers are also known as double wythe masonry walls.
How Does a Cavity Work?
The two skins of a cavity wall are firmly held together by blocks or metal ties. A water barrier is also installed to prevent water and moisture from affecting the inner surface of the wall. Additionally, a flashing component is also incorporated within the wall to provide a passage for water expulsion. The flashing component starts from the inner wall and ends at the weep holes located at the base of the outer wall. The component is typically located near the wall base, to help the maximum collection of water making its way down the wall.
Modern construction methods have allowed for the addition of another cavity insulation layer between the two skins. This insulation layer can be easily added through the slabs, further minimizing the creation of thermal bridges and achieving proper insulation.
