Like the sustainably grown natural forests around the country, the number of interested parties, it is pleasing to note, are growing by the day. These interested parties make up most of what could be considered a natural heritage in the sense that many North American domestics and businesses are still depending on wood in their applications towards building and retaining their homes and small to medium sized businesses.
While there is still some way to go towards creating the one hundred percent sustainable development ideal, farms can be considered a good example of dependence on penta treated wood, mainly in the form of penta poles and/or strips used in the construction of boundaries and farm buildings or barns. Penta (pentachlorophenol) poles are essentially utility poles that have been in common use for more than seventy years.
Market capture remains steady at nearly fifty percent. Like most other wood preservatives, penta acts as a pesticide which, in turn, acts against wood-destroying fungi and insects. Penta wood popularity comes by way of being a highly effective and economically preserving material that is able to control just about every form of wood-destroying agent. Stake tests and actual use has shown that the penta substance can preserve wood anything between eight to twenty times beyond normal service life expectancy.
An oil solution, interestingly, is applied to penta. Properly coated, penta treatments will remain in treated wood products for many years. But only in low concentrations, penta becomes degradable by sunlight and certain bacteria. Over time, the wood surfaces with low concentrations of penta will, of course, deteriorate a lot quicker. Wood that is treated with penta also does little to harm the picturesque effects created by the utilization of wood across the board, if you will.
