EIFS, or Exterior Insulation and Finish System, is a non-load-bearing cladding system that provides thermal insulation, weatherproofing, and an attractive exterior finish for commercial buildings. It is commonly used in New England to enhance energy efficiency and protect structures from harsh weather.

EIFS (Exterior Insulation and Finish System) is considered a water-resistant barrier, not completely waterproof. Modern EIFS systems are designed to repel and manage water through protective coatings, drainage planes, sealants, and flashing systems. When properly installed and maintained, EIFS provides effective moisture protection and energy efficiency.
