Cavity insulation

What is Cavity Insulation?

On a home built with a brick exterior there is often an air cavity left between the brick and the exterior support walls of the structure. Cavity insulation, made of a wide variety of materials, is installed in the air gap to reduce the amount of heat lost through the home's walls. An existing home will need to have the cavity insulation blown into the walls through a properly sized hole to ensure an even fill, whereas during new construction, cavity insulation panels are placed in the air gap as the walls are being erected.

Importance of Cavity Insulation.

A home's structural air cavity, used to reduce the amount of moisture that transfers from the porous brick to the house, is a poor insulator and nearly 60 percent of a home's heat loss in through the walls. Cavity insulation is used to fill the air cavity and contain more heat inside of the home.

Cost Savings from Cavity Insulation.

If a home does not have cavity insulation installed, the energy saving will be substantial. The energy savings will pay for cost of the cavity insulation, including labour, in as little as five years. There are additional benefits to installing cavity insulation beyond the reduced energy bills. Homes that are more energy efficient reduce the amount of greenhouse gases released into the atmosphere and energy efficient homes have a higher resale value.
