EPA has released the first of seven technical guidance modules - moisture control - to assist home builders, subcontractors, architects, and other residential construction professionals in implementing the construction requirements of the Indoor airPLUS labeling program for new homes. The Moisture Control module addresses the construction methods and component materials necessary for managing water intrusion from exterior and interior sources. Best Practice Installation Procedures are provided as additional practices that builders and others may adopt (these practices are not required) as they continue to address indoor air quality.
