How the 2020 (7th Ed) FL Building Code and ASTM Standards Make Stucco Work in Florida

This course takes a deep dive into the specific IBC/IRC and Florida Building Code regarding proper design and application of Exterior Stucco. It first reviews and explains the ASTM C926 and C1063 standards that are the basis of the stucco and lath application standards in the code. It highlights the specific climatic concerns of the warm/humid Florida environment and teaches the proper design for building envelope water management using the ASTM E331 water resistance test listed in the building code. Then using a specific example, the course details and explains the methodology of calculating and designing a wood framed exterior stucco assembly for the proper wind resistance necessary for the Florida hurricane prone climate using ASCE 07 and the ASTM E330 structural wind resistance test in the building code. The course lays out the proper fastening needs for the wind loads and the proper use of sealed face barrier systems to mitigate the water intrusion. Finally, the course suggests options for warranting the envelope and providing a long-term maintenance schedule.
