Insulation is one of the most prominent factors in maintaining the comfort and energy efficiency of Perth homes while protecting them from extreme temperature fluctuations. As with any component of a home, insulation does not last forever. It can sometimes wear, become compromised, or become damaged over time — which can lead to increased electricity costs, decreased comfort, and possible health issues. Many homeowners do not acknowledge that the insulation itself is not the only cost; the long-term cost of ignoring the problem far exceeds the cost of the actual insulation.
