What is the main purpose of spray-on insulation?

The main purpose of spray-on insulation is to provide a seamless thermal barrier. This type of insulation is designed to conform to the surfaces it is applied to, filling in gaps and voids that may exist in more traditional forms of insulation. This seamless application significantly reduces air leakage and improves the overall energy efficiency of a building by minimizing thermal bridging, which occurs when heat transfers through materials that are more conductive than insulation.

Spray-on insulation also creates an effective barrier against both heat loss in the winter and heat gain in the summer, helping to maintain a comfortable indoor temperature and reducing reliance on heating and cooling systems. Additionally, the adhesion properties of spray-on insulation ensure that it remains securely in place, further enhancing its effectiveness over time.

While this method can contribute to faster installation compared to some traditional insulation methods, its primary purpose is centered on thermal performance rather than efficiency in installation time or aesthetic appeal.
