Retrofit Measures for Wall Sheathing

Here you will find the data for Wall Sheathing measures available in the National Residential Efficiency Measures Database. Each measure consists of a before-component, an after-component, and the estimated cost to implement the measure. The measures are listed alphabetically based upon the name of the before-component. Where multiple costs are indicated they must be combined to obtain total measure cost (e.g., fixed ($) and normalized ($/sf) costs).
