Scope: 1 Scope This document outlines requirements for exterior insulation and finish systems ( EIFS ), used in combination with a drained air space as an exterior wall cladding system. The document includes requirements for a water resistive barrier assembly that are used as part of EIFS . This document outlines testing procedures with pass/fail criteria for an exterior insulation and finish system . The procedures cover the liquid applied water resistive barrier, which forms a second line of defense against water penetration, individual material components and the complete system to demonstrate durability . The use of mechanical fasteners is outside the scope of this document. In EIFS , the thermal insulation boards support the base coat with integral glass fibre reinforcing mesh . Systems where the reinforcement is the supporting element of the rendering, e.g. conventional stucco, are not covered by this document.
