What is the recommended gap in insulation in areas prone to termites?

In areas prone to termites, maintaining a small gap of 2 to 3 inches in insulation is important for several reasons. This gap helps to create a barrier between the soil and the wooden structures of a building, which can reduce the risk of termite infestation. Termites thrive in humid and dark conditions, often nesting in soil close to their food sources. By having a gap, it allows for better ventilation and drying, minimizing the dampness that can attract termites.

Moreover, this recommended gap aligns with common building codes and best practices for moisture management, which are crucial in regions where termites are a concern. A gap that is too small may not provide adequate air circulation, while a gap that is too large may not effectively deter termite access or may create other issues with insulation performance. The choice of a small gap of 2 to 3 inches strikes a balance between effective insect prevention and maintaining insulation integrity.
