About this detail

This firestop system detail shows the maximum allowable opening sizes for penetration firestop devices installed within a minimum six inch thick reinforced lightweight or normal weight concrete wall, or alternatively a UL classified concrete masonry unit block wall. The assembly achieves a two-hour F rating, a quarter-hour T rating, and specified ambient and elevated temperature air leakage ratings under ANSI/UL 1479, ASTM E814, and CAN/ULC S115 standards. Openings may be oriented either vertically or horizontally through the wall assembly.
