Ul Number For Concrete Wall

Aci tms 216 1 14 code requirements for determining fire resistance of concrete and masonry construction assemblies lists the minimum equivalent thickness of single layer concrete walls to meet fire resistance ratings ranging from 1 to 4 hours see table on following page.

Ul number for concrete wall.

Ul is an independent third party product safety testing and certification organization. The hourly fire resistance ratings listed are f ratings. Some of our systems also have t and l ratings. Usg provides resources here for our ul wall assemblies for seamless integration into any construction project.
