How Closed-Cell Spray Foam Helps Control Air and Moisture

Closed-cell spray foam forms a rigid, compact structure after application. It generally provides higher thermal resistance per inch than open-cell foam and can act as an effective air-control layer when installed continuously at the required thickness. These properties make it useful to evaluate in assemblies where space is limited or air movement must be controlled. Air control and moisture transport Moving air can carry substantial moisture through gaps in a building en
