I’ve used treated timber and I have also used untreated timber and I can tell you that treated timber when used outside is way better that the untreated one. The main reason for this conclusion is that while the untreated timber is decomposing and going to ruin, the treated version is still going strong.

In the US many of the telephone poles are made from wood treated with preservatives to make sure that they last for a long time and are also impervious to many pests such as termites. Other products offered by the Pacific Wood Preserving Companies include transmission poles, distribution poles, agricultural treated wood products and Pac-Bor treated sill plate. The thing to keep in mind is that they are the most environmentally mindful and innovative wood treater in its marketplace and that is quite rare in this day and age.
