EIFS, also known as synthetic stucco or Dryvit, is a multi-layered exterior finish with four layers – foam insulation board secured to exterior wall surface substrate, base coat of acrylic or polymer-based cement material applied to top of insulation, reinforcement mesh embedded in the base coat material, and textured, decorative finish coat that offers protection.
Stucco is a decorative exterior finish made of sand, cement, lime, and water that has seen a resurgence in popularity because it is affordable, durable, noise-resistant and relatively maintenance-free. It can be textured and tinted and has versatile design capabilities.
