Residential insulation is available in a vast array of options. From batts to loose-fill and fibreglass to wool, you have a wide variety of options to ensure that your choice fits within your budget while also offering you the degree of thermal protection that you need. One solution that has been a staple in commercial spaces but that has only recently experienced a surge in popularity for residential applications is spray foam insulation.

Also commonly referred to as spray insulation, this is one of the most costly solutions that one can invest in. However, it is with good reason that it is progressively becoming the go-to option for the discerning homeowner. Before you discount spray foam as your preferred residential insulation due to the price tag, read the following brief yet thorough outline on what you should know about it.

What advantages does spray foam insulation offer over its traditional counterparts?

The first thing that you should note about spray foam insulation is that, unlike batts and loose-fill that have to be secured onto the surface, it is dispersed into the surface via aerosol. Thus, it can seal the entire area it is being applied onto, since even hard-to-access spaces and tiny crevices will be coated.

The second major benefit of spray foam insulation is that it is fully compliant with Aussie's fire standards. Unlike most other materials, spray foam will not flare up when exposed to flames. Moreover, it is easy to put out once the source of heat has been eliminated. These characteristics make it ideally suited to bushfire-prone locations.

The third pro of choosing spray foam insulation is the bonus of thermal and acoustic insulation that it offers. Once the insulation is installed, your home is not only at minimal risk of disruptions from exterior noises but you also get to improve the thermal efficiency of your residence.

How much will spray foam insulation cost you?

Several factors influence the overall expense of spray foam insulation, so the amount of money you stand to pay can vary vastly from what another household would pay. For instance, the type of spray foam insulation that you choose will affect the cost, with open-cell foam insulation being more affordable than the closed-cell variety.

Furthermore, the scope of the project will also factor into the final cost. As a rule of thumb, the insulation materials and their installation per square metre will cost more if the project entails the entire home rather than a singular room.
