Cavity Wall: Definition and Usage

Cavity wall is a type of construction method that is used to better insulate a structure. It is made up of two walls, which are separated by an air pocket or cavity. This type of construction is commonly used in residential buildings, especially in colder climates.

The inner wall is usually made out of brick, concrete, or stone. The outer wall is usually made out of metal, wood, or vinyl. The air pocket provides insulation and prevents heat from escaping. This helps to keep the building warm in the winter and cool in the summer.

Cavity walls can also be used to help protect a structure from moisture and humidity. The air pocket can also act as a sound buffer, reducing noise from outside sources.

Cavity walls do require routine maintenance. The exterior walls need to be pressure washed and resealed on a regular basis to prevent water from entering the cavity. Inside the structure, the walls should be regularly inspected for cracks or leaks.

Cavity walls are an energy-efficient and cost-effective way to reduce energy costs and provide protection from outside elements. They are also an environmentally-friendly option, as they require little energy to make and can last for a lifetime.
