The PTI preservative imparts very little color to the wood. Producers generally add a color agent or a trace amount of copper solution so as to identify the wood as pressure treated and to better match the color of other pressure treated wood products. The PTI wood products are very well adapted for paint and stain applications with no bleed ...

International Standards For Phytosanitary Measures No. 15 (ISPM 15) is an International Phytosanitary Measure developed by the International Plant Protection Convention (IPPC) that directly addresses the need to treat wood materials of a thickness greater than 6mm, used to ship products between countries.
Sonti Kamesam (1890–30 November 1952) was an Indian timber engineer and scientist who worked at the Forest Research Institute, Dehra Dun. He is best known for his patented wood preservative, ASCU, from the chemical symbols for Arsenic and Copper.
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 ...
Currently, all creosote-treated wood products—foundation and marine pilings, lumber, posts, railroad ties, timbers, and utility poles—are manufactured using this type of wood preservative. The manufacturing process can only be a pressure process under the supervision of a licensed applicator certified by the State Departments of Agriculture.
Pressed wood, also known as presswood, is any engineered wood building and furniture construction material made from wood shavings and particles, sawdust or wood fibers bonded together with an adhesive under heat and pressure. [1]
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 ...
