| Abstract: |
| Atlantic Canada Wood Framing Moisture Survey Moisture causes more problems in buildings than any other single factor. Researchers are discovering that the air quality in air-tight houses with little or no ventilation is quite poor, and that a major contributor to this poor air quality is moulds, mildews, and wood-inhabiting fungi. These are often the result of excess moisture. One of the major contributors of moisture is the framing material. Wood materials used in construction often contain significant quantities of moisture. For example, the framing lumber used in construction today is usually quite wet, or "green." During the first year or two after a house is constructed, the drying lumber releases moisture, causing high relative humidities and condensation problems. This moisture could remain for months or years, depending on construction materials and technical details, leading to material degradation and decay. |
