In May of 2001, Peterson Wood converted 1 of 2 wood treatment cylinders to an alternative wood treatment process called Wolmanized® Copper Azole. In January of 2004, the second treating cylinder was converted. Genuine Outdoor Wood™ carries the same limited-lifetime warranty and uses the same hardware recommendations as CCA. Developed in the mid-80’s, copper azole has been in use since 1992. This proven product protects the same as CCA while being less corrosive than other alternative treatments. Peterson Wood has had great success with copper azole and will continue to provide new cutting edge products to your yard.
