Webinar Description
The design, construction, and installation of smaller punch or ganged glazing systems have been regulated through standards and building codes for decades. However, glazing systems like window wall, curtain wall, sloped glazing, storefront, and the newer glazed architectural structures from other countries are not strictly covered by these codes. Architects, designers, and AHJs have haphazardly turned to various standards developed in North America and other countries in an attempt to regulate their use, but with limited success and inconsistent results.
This shortcoming in regulation was addressed in the 2015 NBC under Sub-section 5.9.3 Other Fenestration Assemblies. The OBC adopted these changes for projects starting in January 2020 under Sub-section 5.10.3. Requirements include resistance to structural and environmental loads, air leakage, water penetration, heat transfer, and condensation resistance. Guidance in Appendix A describes background and intent behind the requirements, as well as definitions. This session will explain the intent and application of these requirements by those who were directly involved in their development in the NBC.
Learning Objectives
- Gain awareness of the new OBC requirements for curtain wall, window wall, storefront glazing, and glazed architectural structures.
- Understand how performance criteria can be demonstrated through code-accepted standards for laboratory and field testing.
- Gain the ability to change architectural practice to reflect these new provisions.
- Learn the definitions of these systems.
