When selecting an air barrier system, each project must be evaluated on climate, construction condition and hygrothermal modeling, which evaluates how moisture and heat will diffuse through your wall system. So while an air barrier is intended to prevent air leakage through a wall, care must be taken to ensure that it also helps minimize the chances for condensation in a wall cavity.

Uncontrolled air flow takes a tremendous toll on a building and its occupants. IntelliWrap vapor-permeable air barrier and water resistive barrier (WRB) membranes promote a wall cavity in which water vapor can be effectively managed, which is particularly important in regions where seasonal humidity and temperatures fluctuate.

Fluid Applied Membranes

IntelliWrap LVP is a fluid-applied, water-based polymer modified air and water barrier. It is designed to provide a flexible, monolithic barrier when applied over a wide variety of construction surfaces, including masonry, concrete, exterior gypsum board, and wood sheathing. It cures to a tough, durable film with excellent elastomeric and crack bridging capabilities. (Vapor Permeable)

IntelliWrap LTVP (low-temp) is a weather resistant barrier coating designed to coat and seal the exterior surface of the sheathing. Using proprietary technology, IntelliWrap LTVP protects the sheathing material from the elements prior to the installation of the exterior cladding while permitting the transmission of excess water vapor from within the wall cavity. (Vapor Permeable)

IntelliWrap LVB (water-based) is a fluid-applied, water-based polymer modified asphalt emulsion air, vapor, water barrier. It is designed to provide a flexible, monolithic air, vapor and water barrier when applied over a wide variety of construction surfaces including masonry, concrete, exterior gypsum board, stone, wood sheathing and metal. It cures to a tough, durable film with excellent elastomeric and crack bridging capabilities. (Vapor Impermeable)

IntelliWrap LVB (solvent-based) is a fluid-applied, solvent-based polymer modified asphalt waterproofing air, vapor, water barrier. It is designed for use as the membrane component in an exterior wall waterproofing system. It forms a tough, durable membrane that bridges shrinkage cracks. (Vapor Impermeable)

Sheet Membranes

IntelliWrap MA is a 3-layer mechanically attached water-resistive barrier (WRB) and air barrier. It is water tight and vapor permeable, protecting the building enclosure from wind-driven rain while allowing moisture within the building enclosure to escape through the membrane via diffusion. Its permeability and air-tightness make it an ideal membrane for energy-efficient construction. (Vapor Permeable)

IntelliWrap SA is a 3-layer self-adhered water-resistive barrier (WRB) and air barrier. It is water tight and vapor permeable, protecting the building enclosure from wind-driven rain while allowing moisture within the building enclosure to escape through the membrane via diffusion. Its permeability and air-tightness make it an ideal membrane for energy-efficient construction. (Vapor Permeable)

IntelliWrap VB is a self-adhering air & water vapor barrier membrane. It is composed of a tough, multi-layer cross-laminated film that is coated with a rubberized asphalt adhesive. A release liner protects the adhesive and is removed as the membrane is installed. (Vapor Impermeable)

Below Grade Membranes

IntelliWrap BGLA (water-based) is a fluid-applied, water-based polymer modified asphalt emulsion air, vapor, water barrier. It is designed to provide a flexible, monolithic air, vapor and water barrier when applied over a wide variety of below-grade vertical surfaces including masonry, concrete, exterior gypsum board, stone, wood sheating and metal. It cures to a tough, durable film with excellent elastomeric and crack bridging capabilities. (Vapor Impermeable)

IntelliWrap BGLA (solvent-based) is a fluid-applied, solvent-based polymer modified asphalt waterproofing air, vapor, water barrier. It is designed for use as the membrane component in a below grade exterior wall waterproofing system. It forms a tough, durable membrane which bridges shrinkage cracks. (Vapor Permeable)

IntelliWrap BGSA is a prefabricated self-adhering sheet-type waterproofing membrane. It is composed of a tough multi-layer cross-laminated film that is coated with a rubberized asphalt adhesive. A release liner protects the adhesive and is removed as the membrane is installed. IntelliWrap™ BGSA is intended as a multi-purpose waterproofing membrane for use in sub-grade applications and under siding, exterior plaster, as a through wall flashing or anywhere it will be protected from long-term ultraviolet exposure.
