Double layered expandable polystrene exterior insulated and finish system, with an intermediate mesh, utilizing at least one layer of very dense expandable polystyrene

摘要

An External Insulated And Fixed System (EIFS) and method for making the same. The method provides a cost effective procedure for constructing an EIFS that can meet current hurricane high impact test protocol, especially for non-combustible EIFS "Systems". A reinforcing high impact layer of fiber glass mesh is eliminated, and a high density compression molded expandable polystyrene board is provided that yields significantly improved impact resistance
