Report providing extensive guidance on controlling moisture in building envelopes through proper selection and installation on air, water, thermal, and vapor barriers.
Document covering basic moisture control principles in the design of above-grade building enclosures; driving rain as a moisture load on walls; a classification system of the various rain control strategies available for walls; and good design practises for walls.
Case study describing a Concord Cape Cod style home designed in August 2008 by architects and engineers at Building Science Corporation, who developed the drawing set and specifications for the high performance custom home in Concord, Massachusetts.
Information sheet with details on a building enclosure designed for Albuquerque, NM, as an example for building enclosures built for hot-dry and mixed-dry climates.
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.
Report investigating implementation of advanced framing in both production and prototype built homes built in a variety of climate regions across the USA.
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.
Article describing the evolution of the IRC to permit class 3 vapor retarders (latex paint) in walls coupled with exterior continuous insulation to allow drying and reduce condensation risk.
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.
Information sheet briefly summarizing double stud with spray foam wall construction including the advantages and disadvantages of this construction strategy.
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.
Report detailing a three-winter study on unvented roof assemblies in a cold climate, assessing insulation material, ridge diffusion vent presence, vapor control membranes, relative humidity, and interstitial airflow. Results indicate that utilizing air-permeable fibrous fill insulations in unvented...
