Source control, ventilation, and filtration are the keys to healthy indoor air quality. Dehumidification is important too.

475 offers the CONTEGA SOLIDO IQ-D tape as a double-sided window tape option. This double-sided tape can be used for “zero-reveal” taping.  This approach can be used on the interior and/or the exterior. Zero-reveal-taping is the simplest and most robust way to air and waterproof the window. Pro Clima has put a lot of thought into airtight window installation methods, and offers additional adhesive strips integrated into their tapes to simplify Zero-Reveal-Taping. They figured out that you can save an incredible amount of time by doing much of the airsealing BEFORE the windows are installed into the rough opening.

When builders began to insulate houses in the 1920s and 1930s, the exterior paint began to peel. … 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.
