When builders began to insulate houses in the 1920s and 1930s, the exterior paint began to peel. Many painters concluded that insulation draws moisture and refused to paint a house if it was insulated. By 1938, the problem was common enough that Architectural Record published an article titled "Preventing Condensation in Insulated Structures." The author, an architect named Tyler Stewart Rogers, argued that insulation was not the problem; indoor humidity was. He proposed a two-part solution: vapor barriers and attic ventilation. Unfortunately, Rogers jumped to prescriptive solutions without fully understanding the problem, says Bill Rose, research architect at the University of Illinois and one of our country's most respected building scientists. Rogers didn't account for the effects of temperature on wood siding, and he didn't address rain leaking in, which Rose says is "the greatest source of water in building envelopes."
