These products were tested and recertified to meet AW Architectural Performance Class requirements set by the North American Fenestration Standard AAMA/WDMA/CSA 101/I.S.2/A440-11 (NAFS). The standard includes criteria for air, water and structural performance. In addition, Wausau expanded the available battery of test reports on these products to include acoustic performance, thermal transmittance and condensation resistance, which are considerations in modernization projects.
