Overview
Polyglass VertiWrap® VPL LT is a single-component, vapor-permeable fluid-applied air barrier membrane engineered for low-temperature application conditions. Designed with advanced SWIFTSET™ technology, VPL LT delivers faster curing and dependable membrane performance even during cooler weather installations.
This seamless air barrier membrane helps control uncontrolled air movement within the building envelope while still allowing vapor permeability for proper wall assembly drying performance.
VertiWrap® VPL LT is specifically designed to maintain workability and curing performance in lower temperature jobsite conditions where standard fluid-applied air barriers may slow down.

FAQs
What is VertiWrap VPL LT used for?
VertiWrap VPL LT is used as a vapor-permeable fluid-applied air barrier membrane for commercial wall assemblies and building envelope protection.
What does the LT stand for?
LT stands for low temperature, meaning this formulation is designed for improved application and curing performance during colder weather conditions.
Is VertiWrap VPL LT vapor permeable?
Yes. It is designed to allow vapor transmission while reducing uncontrolled air infiltration through the building envelope.
Can VertiWrap VPL LT be spray applied?
Yes. It is commonly applied using airless spray equipment, but can also be rolled or brushed depending on the project requirements.
What sprayers are commonly used with fluid-applied air barriers?
Contractors commonly use Graco airless sprayers such as the GH 833, Mark V, Mark X, and Ultra Max II series depending on project size and material requirements.
Do you offer training and support?
Yes. Spray Foam Systems offers equipment support, application guidance, and bilingual customer support for contractors working with air barrier and coatings equipment.
