Moisture Mapping Defining Acceptable Moisture Levels in Wood Framing

Moisture mapping is a valuable technique that allows for the identification and quantification of moisture content within wood framing. This process is essential for ensuring the structural integrity and long-term performance of buildings.

### What is an Acceptable Moisture Level in Wood Framing?

The acceptable moisture level in wood framing varies depending on the wood species, intended use, and location. However, generally, moisture content should not exceed:

– **19%** for structural framing members
– **16%** for sheathing and decking
– **12%** for interior trim and woodwork

Moisture content above these levels can lead to:

– Structural weakness
– Rot and decay
– Fungal growth
– Warping and buckling

### Determining Acceptable Moisture Levels

Moisture mapping surveys are conducted using specialized equipment, such as moisture meters and ground penetrating radar. These tools allow for non-destructive testing and provide accurate measurements of moisture content.

By comparing the measured moisture levels to acceptable thresholds, buildings professionals can determine if moisture levels are within an acceptable range or if further investigation and remediation are required.
