What is treated wood?
There are two types of treated wood: preservative-treated wood and pressure-preservative-treated wood (pressure treated lumber). Wood treatment chemicals delay deterioration caused by fungi (rot) and make wood less appealing to potentially destructive insects. One common misconception is that treated wood is more resistant to water, but that’s not true. Treated wood will soak up just as much water as non-treated wood.
