See General Information for Exterior Wall Systems

GENERAL

This category covers components for exterior wall systems, such as air barriers, air-barrier systems, water-resistive barriers, insulation, substrates, etc., designated for use in specific assemblies covered under Exterior Wall Systems (FWFO). Information concerning the exterior wall assembly details is described in the individual systems. Air barriers are installed for the purpose of controlling unintended movement of air into and out of a building envelope. Water-resistive barriers are installed for the purpose of resisting bulk water penetration and wind-driven rain that penetrates the exterior cladding from intruding into the wall assembly.

Exterior non-load-bearing wall assemblies incorporating these components are investigated to ANSI/NFPA 285, "Standard Fire Test Method for Evaluation of Fire Propagation Characteristics of Exterior Non-Load-Bearing Wall Assemblies Containing Combustible Components," as required by the "International Building Code," or ANSI/NFPA 5000, "Building Construction and Safety Code."

These individual components are not intended to be interchanged between assemblies, but rather are designated for use in a specific design in order that the performance of the system may be achieved. Consequently, the substitution or elimination of components required in a system should not be made unless specifically permitted in the individual system or in these general guidelines.

The materials are installed in accordance with details that directly relate to the established ratings. These components are additionally intended to be installed in accordance with the manufacturer's instructions provided with the material.

Authorities Having Jurisdiction should be consulted before installation and use of these components.
