Guidelines for infiltration reductions in light-frame structures.

Comments on the benefits of tighter house construction and gives a summary of the current tightness levels of the US housing stocks, based on a 300-house survey of infiltration measurements. Looks at 2 case studies of energy-efficient houses both for the details of their construction and for the air quality in the finished houses. Presents a set of drawing details that illustrate specific techniques for reducing infiltration. Includes methods of weatherstripping doors and windows, caulking and sealing, possible leakage points, and installing vapour barriers.
