Betsy and Joe's 100-year-old farmhouse was retrofitted a couple of decades ago in one of Building Science Corporation's early examples of a "deep energy retrofit." Remodeler David Joyce digs into the walls to check the performance of the exterior foam and construction tapes.

By removing the replacement window and the original window frame and then reframing the opening, David makes the viewable area bigger. By using triple-glazed windows, he makes the bigger area more comfortable.
