New Process for Preserving Lumber

Phys.org: Pressure treating – which involves putting lumber inside a pressurized watertight tank and forcing chemicals into the boards – has been used for more than a century to help stave off the fungus that causes wood rot in wet environments. Now researchers at the Georgia Institute of Technology have developed a new method that could one day replace conventional pressure treating as a way to make lumber not only fungal-resistant but also nearly impervious to water – and more thermally insulating.  More about it here at phys.org
