30、 outlines requirements for exterior insulation and finish systems (EIFS), used in combination with a drained air space as an exterior wall cladding system. It also outlines the requirements for water resistive barrier systems that are to be used with EIFS.The EIFS wall cladding system is comprised o
31、f liquid-applied water resistive barrier, an adhesive for attachment of the thermal insulation boards to the substrate, rigid thermal insulation boards, a glass fibre reinforcing mesh embedded in a base coat on the face of the thermal insulation boards and a finish coat.The use of mechanical fastene
32、rs is outside the scope of this document, but is acceptable as a complement and/or as an alternate to adhesive for attachment where the substrate will not support adhesive attachment of the EIFS.In EIFS, the thermal insulation boards support the base coat with integral glass fibre reinforcing mesh.
33、Systems where the reinforcement is the supporting element of the rendering, e.g. conventional stucco, are not covered by this document.This document does not purport to address all the health and safety aspects associated with its use. Anyone using this document has the responsibility to consult the
34、 appropriate authorities and to establish health and safety practices, in conjunction with any existing applicable regulatory requirements, prior to its use.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requireme
