Barrier systems are those cladding assemblies we have tested as single leafs within stated thresholds, for example ASTM E283 and ASTM E331. Advantages include design flexibility and a broader range of applications. Even with these systems, true environmental separation should occur behind the cladding, with a fluid-applied air barrier and continuous insulation.

Please note that NOW Specialties stores all aluminum composite materials and system components in our bonded warehouse, in the original packaging, until fabrication commences. We field-measure and shop-engineer as required to maintain the design intent and construction schedule. The material does not ship directly from the manufacturer to the jobsite.
