EIFS chimney cladding enhances aesthetics and insulation while reducing weight on structures compared to traditional masonry. Proper installation requires a sound, flat substrate like brick or masonry with metal lath if irregular, plus critical flashings: oversized sheet metal chimney caps overlapping sides by 2+ inches with drip edges, kickout flashings where roofs meet chimney sides, and crickets on upslope roofs to divert water. Avoid low-slope EIFS tops to prevent soot staining and sparks; use foam shapes matching the main system for stone-like accents, ensuring sealant joints at material transitions and 4-8 inch ground clearance to resist ice and termites in coastal areas like Norfolk.
