About this detail

A vertical aluminum mullion aligns with a partition wall assembly containing internal insulation. Continuous fire safing with fire sealant fills the three-quarter inch gap at the mullion extension below the edge of the slab, utilizing neoprene at non-rated conditions. An interior mullion snap-on cap extension spans the entire width of the room, finished with paintable two and one-half inch tape on L-metal matching the adjacent wall color. Backer rod and fire sealant seal the joint at the mullion extension below, painted to match the mullion color.
