NatureWood Preservative

The NatureWood wood preservative is a waterborne, alkaline copper quaternary preservative system developed to provide long-term protection of wood exposed in exterior applications. The NatureWood system is based on the well-established effectiveness of copper combined with an organic quaternary compound and is applied to wood by pressure treatment. Copper and quaternary compounds are effective fungicides and termiticides. Together they provide protection from a broad spectrum of fungi and termites. Quaternary compounds are commonly used as swimming pool additives, disinfectants and sanitizers and have antibacterial properties. The active ingredients, copper oxide and quaternary compounds, are dissolved in an alkaline carrier in NatureWood products.

Depending on the desired product application, wood species, and exposure hazard, the NatureWood preservative system may be formulated with a number of specialty additives such as water repellents to enhance product performance.

NatureWood Preserved Wood Product

Properly treated and processed NatureWood products are similar to CCA treated wood products - both are pressure treated, long lasting, durable, clean to the touch and have no objectionable odor. More than a decade of field test performance and commercial use worldwide establishes the proven effectiveness of the NatureWood preservative technology against termites and fungal decay.

NatureWood preserved wood products offer termite and fungal decay protection similar to that of CCA treated wood. Ground contact testing of treated stakes confirms that while untreated SYP stakes fail in less than 5 years, stakes preserved with NatureWood preservatives perform similarly to CCA treated stakes.

Lifetime Residential and Agricultural Limited Warranty

A Lifetime Residential and Agricultural Limited Warranty is offered on NatureWood products at 0.25 and 0.40 pcf retention levels for material used in residential and agricultural applications. See Warranty for specific provisions. An independent third-party quality control is required for the use of the NatureWood trademark and NatureWood Lifetime Residential and Agricultural Limited Warranty.

Regulatory Requirements

The preservative technology in NatureWood products is registered by the EPA as a non-restricted use pesticide and does not require Proposition 65 labeling in California. NatureWood products, as described in National Evaluation Report - NER# 628, meet all major model building code requirements.
