NOW Specialties, Inc. was selected to design, fabricate and install the exterior composite wall system with strong, 4mm Metal Composite Materials that would reduce buckling and oil canning. Fluid applied weather barrier was specified behind the metal panel system, but the demanding requirements of the application went beyond the capabilities of standard products available. The most stringent requirements included:
- Temperatures up to and in excess of 180 °F.
- Self-gasketing capability where fasteners penetrated through the membrane so additional detailing wasn’t required.
- The ability to withstand UV exposure for up to a year without degradation.
A tested system with documented performance was required. With the ability to withstand temperatures up to 240 °F, ExoAir 230 surpassed NOW’s performance requirements with ease. The membrane was formulated to withstand UV exposure so extensive documentation was readily available to match this need. ExoAir 230’s nail-sealability testing made it ideal for NOW's requirement of a product that would self-gasket.
Other components used during construction included ExoAir 110, ExoAir Primer, Spectrem 1 Silicone Sealant, Tremflex 834 Acrylic Sealant and Proglaze SSG Silicone Sealant, which could withstand the airport winds up to 100mph.
