How does continuous insulation relate to air barriers?

Continuous insulation is a crucial component when discussing air barriers because it directly impacts both thermal performance and the integrity of the air barrier system. When continuous insulation is applied properly, it minimizes thermal bridging — which occurs when heat bypasses the insulation through conductive materials like structural elements — by creating a consistent layer of insulation across the exterior of the building. This is important as thermal bridges can allow for significant air leakage and energy loss, making it more challenging to maintain indoor temperatures and energy efficiency.

Moreover, by reducing thermal bridging, continuous insulation also helps in minimizing air leakage. Air barriers are designed to control the movement of air into and out of buildings, and when insulation is continuous, it complements the air barrier's role by ensuring that there are fewer gaps or weaknesses through which air can escape or infiltrate. This synergy between continuous insulation and air barriers is essential for achieving effective building envelope performance, promoting better energy efficiency, and enhancing occupant comfort.

The other options suggest inaccuracies regarding the relationship between continuous insulation and air barriers. For instance, the idea that it creates additional air leaks contradicts the principle that effective insulation and air barriers work together to reduce leaks. Additionally, while insulation installation can be complex, it does not inherently complicate the installation process of an air barrier but
