The inventors of Wolmanized® pressure-treated wood - acknowledged leaders in wood preservation – have introduced their latest breakthrough: a long-sought low-impact preservative based entirely on organic chemistry. This preservative is now being used by Northeast Treaters in the production of new non-metallic Wolmanized® EraWood, the first decking product protected by a nonmetallic solution.
In the bulk of exterior wood uses – everything except in-ground applications – new non-metallic Wolmanized® EraWood stands up to wood-destroying organisms, and satisfied the concerns of demanding consumers. Despite its effective performance, the preservative formulation has low impact throughout its production, distribution, and installation.
This wood is intended for out-of-ground use only.
Most uses for treated wood fall into this category:
For in-ground needs, use Genuine Wolmanized® Residential Outdoor wood that is tagged for ground contact.
The preservative in new non-metallic Wolmanized® EraWood is an unusually effective blend of commonly used organic components. Only 1/10 of the amount of chemicals is needed to provide the same protection as copper-based formulations.
This waterborne preservative consists of tebuconazole, propiconazole, and imidacloprid. Tebuconazole is commonly used as an antimicrobial in adhesives and glues as well as in post-harvest wash for cherry crops. Propiconazole can be found in commonly used textiles and canvas, such as shower curtains, because of its antimicrobial properties. The combination of tebuconazole and propiconazole, both fungicides, has been patented for its synergistic efficacy. The final component, imidacloprid, is an insecticide often used in cat and dog flea control.
Together, the three ingredients result in a formidable defense against wood-destroying organisms in out-of-ground applications.
With the elimination of metals in the preservative, the features of this preservative have been improved to a point unattainable by copper-based counterparts.
Impact on regulatory requirement. There are no issues with copper run-off from storage areas.
Impact on environment. The biocides in the preservative are know to undergo bacterial degradation in soil, and they are not bioaccumulative.
Impact on exposure. Each component of the preservative system is orders of magnitude lower in mammalian toxicity than sodium fluoride, a common ingredient in toothpaste.
