What is one consequence of having unsealed insulation cavities?

The presence of unsealed insulation cavities leads to greater air leakage and energy loss. When insulation cavities are not properly sealed, air can freely flow in and out of the space, allowing conditioned air from within the building to escape. Simultaneously, unconditioned outside air can enter the building, leading to increased heating and cooling demands. This condition hampers energy efficiency, as HVAC systems must work harder to maintain comfortable indoor temperatures, resulting in higher energy bills and a less comfortable living environment. Additionally, air leaks can introduce moisture, contributing to potential issues like mold growth and reduced indoor air quality. Thus, sealing insulation cavities is crucial for maintaining energy efficiency and overall building performance.
