Monitoring of Unvented Roofs with Diffusion Vents and Interior Vapor Control in a Cold Climate

Building Science Corporation and partners will evaluate the use of a vapor control membrane, or diffusion vent, which could substantially reduce the risk of moisture issues in roof assemblies with fibrous insulation. This project will field test this solution in a cold climate new construction test house over three years, and will also test the approach in a high impact existing home weatherization application to be determined through stakeholder engagement.
