Moisture Mapping plays a crucial role in ensuring the longevity and integrity of wooden structures. Understanding wood moisture content and its effects is essential for building and maintaining healthy and lasting infrastructure.

### Wood Moisture Content

Wood moisture content (MC) refers to the amount of water present within the wood fibers. MC is typically expressed as a percentage of the wood’s dry weight. Due to its hygroscopic nature, wood absorbs and releases moisture from the surrounding environment, leading to fluctuations in MC.

### Why is Moisture in Wood Bad?

Excessive moisture in wood can have detrimental effects on its properties and performance:

– **Structural Integrity:** High MC weakens wood’s tensile and compressive strength, potentially compromising its load-bearing capacity.
– **Durability:** Moisture creates a favorable environment for mold growth, decay, and insect infestation, reducing wood’s resistance to damage.
– **Stability:** Moisture fluctuations can cause wood to swell and shrink, leading to warping and cracking.
– **Thermal Performance:** Excess moisture impedes heat transfer, reducing wood’s insulating properties.
– **Fire Safety:** Dry wood is less flammable than wet wood, increasing the risk of fire spread in moisture-laden environments.
