Wood Moisture Content A Comprehensive Guide

Moisture Mapping

Moisture Mapping is a technique used to measure the moisture content (MC) of wood and wood-based materials. The process involves the use of a moisture meter, which can be inserted into the wood to measure the electrical resistance. The resistance is then converted into an MC reading, which is typically expressed as a percentage.

Wood Moisture Content

Wood MC is a crucial factor that affects the properties and performance of wood and wood products. It influences the wood’s strength, stability, and durability. High MC can lead to problems such as rot, decay, and mold growth. Conversely, excessively low MC can cause wood to become brittle and prone to cracking.

Ideal MC for Firewood

The ideal MC for firewood varies depending on the type of wood and the intended use. However, as a general rule, the MC of firewood should be between 15% and 25%. This range provides optimal burning efficiency and reduces the risk of sparking or creosote buildup.

  • Too High MC: Firewood with a MC above 25% will produce more smoke, less heat, and is more likely to produce creosote.
  • Too Low MC: Firewood with a MC below 15% will burn too quickly and produce less heat.
