Exterior Insulation Finish Systems (EIFS)
Exterior Insulation and Finish System (EIFS) is a non-load-bearing exterior wall cladding system that consists of Insulation board, made of polystyrene or polyisocyanurate foam, which is secured to the exterior substrate with a specially formulated adhesive and/or mechanical attachment.
A durable, water-resistant base coat is applied on top of the insulation and reinforced with fiber glass mesh for added strength and is impact resistance. An attractive and durable finish coat is applied typically using acrylic co-polymer technology, which is both colorfast and crack-resistant. It is available as either a barrier system or a drainage system.
