### What is Moisture Mapping? Moisture Mapping is a non-destructive technique used to identify areas of excessive moisture within building materials, such as wood framing. This method involves scanning the material using specialized sensors to measure moisture content. Moisture Mapping is crucial for preventing damage caused by moisture, including mold growth, structural degradation, and health issues. ### Acceptable Moisture Levels in Wood Framing Acceptable moisture levels in wood framing vary depending on the type of wood and its intended use. However, general guidelines recommend maintaining moisture content below 15% for interior structural framing and below 12% for exterior structural framing. ### Factors Affecting Moisture Levels Several factors can influence moisture levels in wood framing, including: * **Humidity:** High humidity can cause moisture to penetrate wood. * **Water Leaks:** Leaks from roofs, windows, or plumbing systems can contribute to excessive moisture. * **Condensation:** Warm, moist air can condense on cold surfaces, resulting in moisture buildup. * **Inherent Moisture:** Wood naturally contains moisture that can vary depending on the species and drying process. ### Detecting Excessive Moisture Moisture Mapping is an effective way to detect excessive moisture in wood framing. If Moisture Mapping reveals moisture levels above acceptable limits, it is important to identify the source of the problem and address it promptly to prevent damage to the structure and ensure occupant health and safety.
