A basement where the walls have not been drywalled or plastered.
Basement walls can leak when it rains due to water seeping through cracks or gaps in the foundation. The pressure from the saturated soil outside the basement can also force water into the walls. Additionally, poor drainage around the foundation can lead to water pooling and eventually finding its way into the basement.
Using an insulation blanket for basement walls can help regulate temperature, reduce energy costs, prevent moisture buildup, and improve overall comfort in the basement.
