Air barriers are only effective when designed as a holistic, continuous system. Tremco offers the industry's only comprehensive vapor-permeable and vapor-retarding air barrier systems formulated for compatibility, including engineered transitions to ensure continuity at critical terminations and connections.
Tremco has passed full-scale NFPA 285 tests with air barrier membranes, sealants, transitions; ASTM E2357 air leakage testing; and ASTM E331 water leakage testing…all with the same air barrier systems. View the test.
ExoAir Vapor-Permeable Air Barrier Systems are designed to seal walls from air infiltration and exfiltration, while allowing vapor molecules to pass through so they do not get trapped within the wall. Trapped moisture vapor could cause condensation to occur within the wall cavity which can lead to structural deterioration and shortened structure life.
ExoAir Air & Vapor Barriers are designed to block moisture vapor as well as air
ExoAir 120 - ExoAir® 120 Fluid-Applied Air & Vapor Membrane is a monolithic, elastomeric membrane designed to seal exterior above-grade wall assemblies and prevent air infiltration/exfiltration, vapor transmission and water penetration.
ExoAir 110/110LT - ExoAir® 110 and 110LT Self-Adhered Air and Vapor Membranes are 36 mils (.90 mm) of self-adhering SBS rubber asphalt laminated to a 4 mil (.10 mm) cross-laminated, high-density polyethylene film with a siliconized release liner.
Transition Assemblies assure that tie-ins or transitions from air barriers to window or curtain wall systems will not be a source of problems from air and moisture infiltration into a structure. Tremco provides PROVEN solutions from a single source to simplify the installation of transitions from window systems to wall assemblies.
Patented engineered transition assemblies for connections from the air barrier system to the window system.
Tremco’s T3 Building Enclosure Solutions seal out weather around windows and doors while sealing in comfort and energy savings. The T3 approach employs three layers that work in unison: an outer layer that provides weather protection while allowing for vapor diffusion; a middle layer that provides a thermal barrier; and an airtight, vapor-resistant inner seal.
ExoAir Duo Membrane - ExoAir® Duo Membrane is composed of a tear-resistant fabric embedded into a polyethylene copolymer with a large expansion pleat for variable joint sizes and absorption of movement to create a unique window flashing membrane.
ExoAir Air Barrier Systems include sealants, mastics and other system accessories formulated to ensure continuity, compatibility and long-term performance.
ExoAir Primer - ExoAir® Primer is a VOC-compliant adhesive primer formulated for use with ExoAir 110/110LT and ExoAir TWF.
ExoAir Termination Mastic - ExoAir® Termination Mastic is a single-component mastic formulated for use sealing or repairing ExoAir Air & Vapor Barriers.
ExoAir TWF - ExoAir® TWF (Thru-Wall Flashing) is a 40-mil (1.0 mm) composite sheet of 32 mils (.80 mm) of self-adhering SBS rubberized
asphalt laminated to an 8-mil (.20 mm) cross-laminated, high-density polyethylene film with a siliconized release liner.
