Steve Fronek
Wausau Window and Wall Systems

Building design professionals’ desire to provide occupants with expansive views and a connection to the outdoors has led manufacturers to develop new and innovative exterior door systems. These can be used in retail, residential or mixed-use environments to access terraces, patios, decks, outdoor seating areas, mall fronts, balconies and lanais. Choices include storefront doors, architectural terrace doors, folding doors, and sliding glass doors – in both conventional and European “lift and slide” options.
This Wausau presentation presents the characteristics of each balcony door option, along with their respective functionality and inherent performance limitations.

Topics include fenestration provisions of the International Building Code, some key local/regional codes, determination of design criteria, testing and evaluation. Accessibility, energy efficiency, acoustical performance and condensation resistance are addressed at a high level. As the fenestration industry’s primary standards development organization, American Architectural Manufacturers Association (AAMA) standards are reviewed.
