About this detail

An insulated metal panel bears on a 16-gauge galvanized steel base channel set over a concrete foundation with a waterproofing membrane. A heavy bead of butyl sealant is positioned in the warm side corner of the channel, underneath the base channel, and below the membrane. A 26-gauge trim piece is set in a continuous bead of sealant and secured to the insulated metal panel using fasteners installed per the manufacturer specifications. Prefinished metal base trim is sealed at the top with pourable urethane and a marriage bead tying into the panel joint sealant. Exterior grading and paving occur at the base, maintaining a minimum clearance relative to the floor line.
