How can environmental conditions impact the installation process?

Environmental conditions play a crucial role in the installation of air barriers, and one of the most significant factors is the condition of the substrate. For a successful installation, it is vital that the substrate is clean, sound, and dry. A clean surface ensures proper adhesion of the air barrier material, as contaminants like dust, oil, or moisture can interfere with the bonding process.

Furthermore, a sound substrate is necessary to provide structural integrity, preventing issues such as cracking or deterioration over time that may compromise the air barrier's effectiveness. Lastly, a dry substrate is essential, as moisture can lead to adhesion problems and could promote mold growth if trapped behind the barrier. This focus on the substrate's condition highlights the importance of environmental factors in creating a reliable air barrier system that effectively reduces air leakage and enhances building energy efficiency.
