What is pressure treated lumber?
In: Engineering
Wood is naturally very porous. This creates a huge number of places for moisture damage to start, fungi to take root, etc.
Pressure treated wood has preservatives applied to it and then is placed in a highly pressurized chamber. The high exterior pressure forces the preservative chemicals deep into the pores of the wood, so it is not merely an exterior coating.
This makes it far more resistant to rot, fungi, and insects.
