Air Guard VPA is a weather-resistant barrier coating designed to coat and seal the exterior surface of the sheathing. It protects the sheathing material from the elements prior to the installation of the exterior cladding while allowing the transmission of excess water vapor from the structure.
Air Guard VPA is an essential component of a weather-resistant barrier system which has been tested and is compliant with ICC ES.
AC 212 requirements for application to plywood, oriented strand board, and impregnated fiberboard (blackboard) sheathing.
The Air Guard VPA system includes:
• Air Guard VPA Membrane
• Air Guard VPA Joint Sealant
• Air Guard Joint Fabric

Air Guard VPA is an environmentally friendly, water-based membrane. It does not contain any solvents and there are no storage, handling, or VOC restrictions. It does not produce any odors, and it is safe for both the applicator and any other personnel employed at or visiting the job site. Air Guard VPA is installed by GMX Authorized Applicators to ensure the highest quality, professional application.
