You will find four comparable heat treatments — Westwood, formulated in the United States; Retiwood, produced in France; Thermowood, created in Finland by VTT; and Platowood, produced from the Netherlands. These procedures autoclave the treated wood, subjecting it to pressure and heat, as well as nitrogen or h2o vapour to control drying within a staged remedy procedure starting from 24 to forty eight hours at temperatures of one hundred eighty °C to 230 °C depending on timber species. These processes maximize the durability, dimensional security and hardness of the treated wood by at least just one course; even so, the treated Wooden is darkened in colour, and you'll find variations in specific mechanical properties: Especially, the modulus of elasticity is greater to 10%,[citation essential] and the modulus of rupture is diminished by 5% to twenty%;[citation desired] Hence, the treated Wooden necessitates drilling for nailing to prevent splitting the wood.
PTI tension treated wood merchandise are rather new to the market position and therefore are not still widely offered in setting up supply retailers.

Boric acid, oxides and salts (borates) are successful wood preservatives and therefore are supplied under many manufacturer names throughout the globe. Just about the most common compounds utilized is disodium octaborate tetrahydrate Na2B8O13·4H2O (normally abbreviated DOT). Borate treated Wooden is of very low toxicity to people, and isn't going to comprise copper or other weighty metals. Nevertheless, compared with most other preservatives, borate compounds never turn into fastened from the wood and may be partially leached out if uncovered repeatedly to drinking water that flows absent as opposed to evaporating (evaporation leaves the borate powering so isn't an issue). Despite the fact that leaching will not likely Generally minimize boron concentrations beneath effective ranges for stopping fungal progress, borates should not be employed the place they will be exposed to recurring rain, drinking water or floor Get in touch with Except the exposed surfaces are treated to repel drinking water.
Particulate (micronised or dispersed) copper preservative engineering has long been introduced inside the US and Europe. In these systems, copper is floor into micro sized particles and suspended in water in lieu of dissolved, as is the situation with other copper goods which include ACQ and copper azole.
