Widely used in buildings ranging from retail/office complexes to hospitals, storefront and window wall systems are specified for ground-level fenestration and entrances, and for punched and horizontal bands (or ribbons) of windows.
The American Architectural Manufacturers Association (AAMA) released its “U.S. Industry Statistical Review and Forecast,” highlighting the window, door, and skylight market trends. The forecasts are based on projections of construction activity as of March 2015.

American Architectural Manufacturers Association/Window and Door Manufacturers Association/Canadian Standards Association (AAMA/WDMA/CSA) 101/I.S. 2/A440, serves as the basis for product certification as required by the International Building Code (IBC).
After multiple years of collaboration, the American Architectural Manufacturers Association (AAMA), CSA Group, and Window & Door Manufacturers Association (WDMA) have released a ‘user guide’ to the 2011 AAMA/WDMA/CSA 101/I.S.2/A440, North American Fenestration Standard/Specification (NAFS).
