The American Wood Protection Association (AWPA) recommends that all treated wood be accompanied by a Consumer Information Sheet (CIS), to communicate safe handling and disposal instructions, as well as potential health and environmental hazards of treated wood.
Here, is the green mass of the wood, is its oven dry mass (the attainment of constant mass generally after drying in an oven set at 103 ± 2 °C (218 ± 4 °F) for 24 hours as mentioned by Walker et al., 1993). The equation can also be expressed as a fraction of the mass of the water and the mass of the oven dry wood rather than a percentage.
Thermally modified wood is engineered wood that has been modified by a controlled pyrolysis process of wood being heated to (> 180 °C) in an oxygen free atmosphere. This process changes to the chemical structures of wood's cell wall components lignin , cellulose and hemicellulose which decreases its hygroscopy and thus increases dimensional ...
The moisture content of wood is measured by the weight of water as a percentage of the oven-dry weight of the wood fiber. The key to controlling decay is controlling moisture. Once decay fungi are established, the minimum moisture content for decay to propagate is 22 to 24 percent, so building experts recommend 19 percent as the maximum safe ...
Planning for wood finishing also involves being aware of how the finishing process influences the result. Careful handling of the wood is needed to avoid dents, scratches and soiling with dirt. [6] Wood should be marked for cutting using pencil rather than ink; however, avoid hard or soft pencil. HB is recommend for face work and 2H for joint ...

The copper in ACQ treated wood accelerates corrosion of galvanized steel fasteners (such as nails and screws) 10 times or more in comparison with CCA-treated wood. Stainless steel (AISI 316) is not affected. [7] Aluminium and Galvalum fasteners should be avoided. [8] One should use fasteners made of hot-dipped galvanized steel, copper, or ...
