About this detail

A curtain wall head connection meets a metal canopy soffit. The assembly incorporates continuous backer rods and sealants alongside a silicone transition sheet adhered to the curtain wall shoulder and clamped by a pressure plate. Poly-SAM and FF-SAM weather-resistive membranes lap over the rough opening framing and extend onto the soffit sheathing with designated minimum overlaps. An insect screen is integrated at the soffit condition, and composite shims position the metal flashing. Gypsum wallboard transitions utilize a J-bead with a paintable sealant joint.
