What is the purpose of the insulation and vapor barrier inspection?

The purpose of the insulation and vapor barrier inspection is to confirm thermal efficiency. This inspection is crucial because it ensures that the insulation is installed correctly and that the vapor barrier is effectively preventing moisture from penetrating the wall assemblies. Proper insulation significantly influences the energy performance of a building by limiting heat loss in winter and reducing heat gain in summer, which enhances the overall thermal efficiency of the home.

This inspection not only helps in achieving energy efficiency but also plays a key role in the comfort of the occupants and the longevity of the building materials by preventing condensation issues. When insulation and vapor barriers are in place and functioning as intended, they contribute to reduced energy costs and a more sustainable building envelope.
