EIFS (Exterior Insulation and Finish System)

"A multi-layer exterior wall cladding combining rigid foam insulation, a base coat with embedded mesh, and a synthetic stucco-like finish. Common on modern residential and commercial buildings in the US."

In detail

EIFS improves thermal performance and allows wide design flexibility. Early 'barrier' EIFS suffered moisture issues in the 1990s; current 'drainage' EIFS systems include a weather-resistive barrier and drainage plane behind the foam. Professional installation and proper flashing are critical.
