Air Barriers
Incorporating a continuous air barrier
system in a building envelope is a complex issue. Specifying the right
system and using it in the right way is critical to ensuring building performance
and eliminating significant problems for a building and occupants alike.

Getting the performance and protection
you need depends on selecting the
right system from a manufacturer with
the technical expertise and modeling
tools to evaluate your design against
real-world conditions. Whatever the climatic
conditions or wall assembly components
or design, Tremco has an appropriate
system to fit the requirements. Our technical
support team will provide a complete wall
analysis using the WUFI® modeling tool to
determine the system requirements
and the appropriate placement. The best system
can then be determined -- our ExoAir 100 Series impermeable system or, where seasonal
temperatures and moisture variations are
high, our ExoAir 220 Fluid-Applied Vapor
Permeable Air Barrier Membrane. To ensure a comprehensive solution, Tremco
provides all the compatible ancillary products
necessary to provide continuity from the
ExoAir Thru-Wall Flashing Membrane
to ExoAir Mastic, Primers, compatible
sealants and even a patent-pending solution
to provide the critical tie-in to rough openings - new Proglaze® ETA Engineered Transition
Assembly.

Needham High School - Needham, MA
A key decision pivotal to the long-term viability of the renovation and expansion done at Needham High School was the selection of a materials supplier capable of providing a comprehensive building envelope solution, including below-grade waterproofing that could be applied over the existing building’s concrete foundation wall, flashings and window connections as well as the air barrier system to ensure compatibility of components and single-source accountability.

The air barrier system provided by Tremco included the ExoAir 120 Fluid-Applied Air & Vapor Barrier Membrane for use over the DensGlass® exterior sheathing board, the ExoAir 110 and 110LT (Low Temperature) Self-Adhered Air & Vapor Barrier Membranes, ExoAir TWF Self-Adhered Thru-Wall Flashing Membrane and ExoAir primer. Tremco’s Tremflex® 834 Siliconized Acrylic Latex Sealant was used to seal the seams in the DensGlass and Tremco’s Vulkem® 116 one-part, moisture-curing polyurethane sealant as a mastic for the edge of the self-adhered membrane to serve as a termination seal. Spectrem® 3 Silicone Sealant was used to seal various window components and create seals between the window and self-adhered membrane.
