Attributes of Tyvek®: Air Barrier

Properly installed Tyvek® WRBs can drastically reduce air leakage, thereby reducing moisture penetration in the walls, and increase energy savings, as well as comfort. In this lesson, you will examine the effects of air leakage in a building and focus on the different types of test procedures used to evaluate the air resistance of building components and wall systems

Learning Objectives

At the conclusion of this lesson, you will be able to:

• Understand how air infiltration resistance of WRBs is evaluated
• Identify and explain air barrier test methods for materials, assemblies and whole buildings
• Cite the advantages and disadvantages of different air-infiltration test methods
• Understand the ABAA Air Barrier Evaluation process
• Understand how air barriers contribute to improved energy efficiency
• Understand why DuPont Building Envelope Solutions products are a good choice for an establishing an effective air barrier
