Overview
Polyglass VertiWrap® VPL LT is a single-component, vapor-permeable fluid-applied air barrier membrane engineered for low-temperature application environments. Featuring advanced SWIFTSET™ technology, this membrane delivers faster curing performance and dependable air barrier protection during cooler weather conditions.
The seamless monolithic membrane helps reduce uncontrolled air movement through the building envelope while still allowing vapor permeability for proper wall assembly drying performance.
The 55 gallon drum configuration is ideal for larger commercial wall assemblies, extended spray applications, and contractors using high-production airless spray equipment.
