Abstract

Information about tensile properties of exterior insulation finish system (EIFS) laminas has been unavailable to the engineering profession. Knowledge of the tensile properties of the reinforced laminas over the exterior surface of the insulation is key to 1) comparing EIFS performance and 2) establishing rules for spacing expansion and control joints in EIFSs for different thicknesses in different climates. This is a report that 1) establishes a procedure for tensile tests that may become an ASTM standard and 2) presents first-cut results on a variety of EIFS laminas, presented generically and anonymously. The paper discusses the results in detail and discusses what remains to be done to establish design guidelines for expansion and control joints in EIFS applications.

Keywords:
insulation, exterior insulation and finish system, EIFS lamina, tensile strength, tensile modulus, expansion joints, cracking
