Report providing extensive guidance on controlling moisture in building envelopes through proper selection and installation on air, water, thermal, and vapor barriers.
Research study discussing how housewraps restrict or permit the passage of water molecules based on size, but cannot control the direction in which the water vapor molecules move.
Case study describing a 2013 DOE Building America Top Innovation for the installation of rigid foam insulation on the exterior of home roofs and walls as a thermal, air, and moisture barrier.
Research study describing a number of promising foundation and basement insulation strategies that can meet the requirement for better thermal control in colder climates while enhancing moisture control, health, and comfort.
Report explaining moisture-related concerns for high R-value wall assemblies and discusses past Building America research work that informs this study.
Report exploring four questions to determine the level of risk associated with adding drained exterior insulation to the exterior of an existing home during an energy retrofit.
Research study developing baseline engineering analysis to support the installation of thick layers of exterior insulation (2 in. to 8 in.) on existing masonry walls and wood framed walls.
Report describing wall assemblies that use layers of rigid exterior insulation thicker than 1-½ inch and require a secondary cladding attachment location exterior to the insulation.
Measure Guideline research report providing simple, long term, and durable solutions when using tapes and flashing membranes in conjunction with the exterior face of rigid polymeric foam sheathing to create the drainage plane of a wall system.
