Problem Definition Study of Requirements for Vapor Retarders in the Building Envelope.

摘要

This document provides a state-of-the-art review and evaluation of current design criteria for vapor retarders. It also suggests general criteria for vapor and air leakage control in Navy building envelopes and recommends specific RDT&E to resolve conflicting criteria, develop remedial measures for existing buildings and prepare guidelines for new construction to prevent the types of moisture and fungus problems currently being experienced, particularly in tropical and subtropical environments.
