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.
Article describing research encouraging use of exterior insulation to warm interior sheathing surfaces in walls and roof assemblies to reduce the likelihood of condensation during cold weather
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.
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 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...

Research study describing the impact resistance performance of advanced framed wall systems with insulating sheathing as the primary sheathing from wind blown debris.
How hard can it be to insulate a flat sheet of concrete? I mean you only have three choices – on the top, on the bottom, or on the edge. OK, you might have some combination of the three as well.
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.
Article describing the importance of air sealing, insulation, and roof ventilation in reducing the likelihood of ice dam formation on roofs in cold snowy climates.
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.
Case study describing a 2013 DOE Building America Top Innovation about construction of net-zero energy ready homes, by several builders working with various DOE Building America research partners including Steven Winter Associates, Building Science Corporation, Home Innovation Research Labs, IBACOS...
Report discussing how to create livable space in the attic that meets IRC code requirements by either creating a ventilated roof assembly, or and unvented attic assembly.
