Overview
Polyglass VertiWrap® NPL is a single-component, vapor-permeable fluid-applied air barrier membrane engineered for commercial wall assemblies and building envelope applications. Designed to create a seamless monolithic membrane, VertiWrap® NPL helps reduce uncontrolled air infiltration while maintaining vapor permeability for proper wall drying performance.
The 55 gallon drum configuration is ideal for contractors handling larger commercial spray applications requiring extended run times, reduced material changeovers, and higher production efficiency.
The 55 gallon drum size supports production-scale fluid-applied air barrier installations using professional airless spray equipment commonly found on commercial construction projects.
