ABSTRACT
Building air leakage issues are described in detail in this entry. The advantages and disadvantages of the most popular techniques and materials used to reduce air leakage are discussed. Information concerning the most often missed avenues for air leakage through penetrations and air flow bypasses is also provided.Each major building component that contributes to air leakage, such as floors, ceilings and walls, is described in detail. The proper application method for each technique used to reduce air leakage is explained in both the text and illustrations. Measurement techniques utilizing blower door technology are also introduced. These techniques have been used to measure the success of the goal of reducing unintended building air leakage.
