EP7: Commercial shaftwall enclosure design and construction essentials

Understand these critical life safety systems to avoid costly installation errors The gypsum board shaftwall system was first implemented in 1973 to accommodate increasingly tall buildings and was first used in the World Trade Center. Shaftwall assemblies enclose all manner of shafts: elevators, stairs, trash chutes and ventilation ducts to name a few. They are designed to prevent fire from spreading between floors via these shafts and to protect stairways as an escape route for building occupants during fires. Gypsum board is lighter than traditional shaft enclosure materials, such as masonry, and provides efficient and economical installation. In this episode, Sam Halverson, construction services manager with the 1-800-NATIONAL Construction Services team, talks with host Chris Whitmire about why it's important to correctly design and install shaftwall enclosures.
