This Treated Lumber Effectively Resists Both Water and Mold

Pressure-treated wood is commonplace in building because of its ability to withstand rot but requires a slew of chemicals to be enhanced, so this treated lumber has been created as an eco alternative.
The new lumber treatment was developed by a team of researchers at Georgia Tech led by Assistant Professor Mark Losego and consists of atomic layer deposition. This process puts wood in a low-pressure chamber before flooding it with metal oxide gas; this permeates the wood and forms a coating on the inner structure to prevent the lumber from absorbing water.
The treated lumber is resistant to mold growth and is even less thermally conductive than traditional wood, which could mean less heat loss when used in building.
