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 Counter Flashing
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.
