Everything You Need to Know about Cavity Walls

A cavity wall is generally provided for insulation, structural stability, and protection from water and moisture infiltration. The construction of a cavity wall is fairly straightforward and consists of two exterior walls with a gap or cavity between them. This cavity serves as an air barrier that helps to keep air from entering the home, while also providing extra insulation and preventing moisture from entering.

Benefits of Cavity Walls

Cavity walls provide several benefits when it comes to the construction and insulation of a home. They are a great way to insulate the home, since the air space between the two walls acts as an insulator, trapping the warm air inside. This helps to keep the home warm during the winter and cool during the summer. Cavity walls also provide protection from moisture, as the air gap between the walls helps to keep out any moisture that may enter the home. Additionally, cavity walls can provide extra structural stability to the house by providing extra support to the walls.

Materials Used in Cavity Walls

Cavity walls are usually constructed using two layers of masonry, such as brick, stone, or stucco. The two layers are separated by a gap or cavity, usually around 2 inches wide. The outer layer of masonry is usually the structural layer and provides the most support, while the inner layer is the insulation layer. Depending on the type of insulation used, a third layer of insulation can be added to the cavity wall. This layer helps to further increase the insulation of the wall.

Installation of Cavity Walls

Cavity walls are generally installed by a professional contractor. The contractor will first prepare the area by making sure the walls are level and flat. Then, the contractor will install the two layers of masonry, making sure to leave a gap or cavity between them. The contractor will then fill the gap with insulation, such as foam or fiberglass, and seal the wall with a waterproof membrane. Finally, the contractor will finish the wall with an appropriate coating, such as paint or stucco.

Maintenance of Cavity Walls

Cavity walls can last for many years with proper maintenance. The walls should be inspected regularly to ensure they are in good condition and any cracks or other damage should be fixed promptly. Additionally, the insulation should be checked regularly to make sure it is still providing the correct insulation value. Finally, the waterproof membrane should be inspected and replaced if it is damaged or has aged significantly.

Conclusion

Cavity walls are a great way to provide insulation, structural stability, and protection from water and moisture infiltration. They are relatively easy to install and can last for many years with proper maintenance. If you are considering installing a cavity wall, it is important to make sure you hire a professional contractor to do the job correctly and to ensure the wall is installed properly.
