About this detail

The exterior storefront window jamb assembly integrates a storefront frame with metal panel Type 2 cladding and continuous building insulation. An air-water barrier membrane, designated as step 10, aligns with a foil-faced self-adhering membrane at step 5A. The transition between the exterior metal panel and the storefront frame is sealed with backer rod and sealant at step 8. An interior backer rod and sealant air seal, designated as step 12, finishes the perimeter joint at the storefront frame step 7F.
