While There May Be Alternative Means to Achieve Closure and Termination, Accessories Developed Specifically for CI Stucco Systems May Provide Simplified Solutions and Detailing.
The thermal performance of a stucco clad exterior wall assembly has traditionally been achieved by installing insulation in the wall cavity. However, with design trends and energy codes driving the need for more thermally efficient walls, incorporating continuous insulation into the wall assembly may be a necessity depending on the compliance path used to achieve energy efficiency, type of substrate, and climate zone.
For example, compliance with Table C402.1.3 of the 2018 International Energy Conservation Code using the prescriptive R-value method for commercial buildings requires R7.5 CI or higher on above grade, metal framed walls in all but the warmest climate zones across the United States.
