Cavity walls are made with two different walls for one purpose and with some space or cavity in between. The two separate walls are known as leaves of cavity walls. The inner wall is an internal leaf and the outer wall is an external leaf. A hollow wall is another name for a cavity wall.

The thickness of a cavity wall of the inner and outer wall might be the same or the inner wall can be thicker than the outer wall. The cavity wall hollow will never exceed 100mm and it has a uniform height.

The purpose of a cavity wall is to prevent rain penetration to the wall’s internal surface. It is important that the cavity walls are not bridged. Your masonry contractor can help you with this.

Prevents Moisture

The top advantage of a cavity wall is the prevention of moisture. If there is no solid wall to wick up the moisture from external walls and draw it in, the interior leaf will stay dry. With a damp-proof course, cavity walls offer all the moisture protection you need.

Prevents Dampness

A cavity wall will check the prevention of dampness from the outside to the inside of your building in the best way compared to a solid brick wall with the same thickness.

Sound Insulation

Lacking interior structure between the leaves will prevent sound transfer. This is very helpful when it comes to creating soundproof rooms or preventing noises from the neighborhood that making their way into your home or office.

Reduces Carbon Footprint

If most of your home is heated by electricity or gas, generating energy will involve burning fossil fuels, which is bad for the environment. If the heat leaks through the walls, then that energy is wasted. Therefore, you would have to use more to maintain the temperature. That means higher demand for energy, and more generation is required. If all homes were more efficient, the carbon footprint would drop.

Insulates Heat

The cavity wall’s ability to insulate better compared to a solid wall with the same overall thickness is a huge advantage. The trapped air and decreased thermal bridging reduce heat loss during winter and it helps prevent conditioned air from leaving the space during hotter months.

Saves Energy

It can be very effective and brings great energy savings, so it has a higher payback compared to other measures. Unlike other kinds of insulation, cavity wall insulation cannot be installed without a professional, but it is not expensive to do so as well. Insulation costs are going to vary based on which country you are in.

Saves You Money

When heat/loss is reduced through the walls of the house, cooling bills are going to fall. You can save about 35% when cavity wall insulation is added to your home with ceiling insulation. You can have bigger savings if you choose to lower the thermostat.

Where to Install a Cavity Wall

If your home has a veneer or double brick walls, there is a cavity between the internal and external brickwork/timber frame which you can use to install insulation. However, wood cavity walls, concrete walls, weatherboard and most forms of walling have negligible cavities or cavities that are dangerous to access. Therefore, it is not good to retrofit the insulation of a cavity wall, but insulative cladding can be added to the wall exteriors. A weatherboard wall can be insulated by pricing off boards for more access to the gaps between replacing them and studs or drilling holes through the internal walls.
