NatureWood NER Report |
NatureWood preserved wood is offered as an alternative to traditional CCA pressure treated wood. NatureWood preserved wood products provide retailers, treaters, consumers, builders and architects an option in their selection of pressure treated wood products. The preservation technology in NatureWood products has been commercially used since 1991 throughout Europe, Asia, and the United States. For many backyard and commercial projects such as decks, fences and landscaping, NatureWood products are an ideal alternative to traditional pressure treated wood. Here's why:
Characteristics of the NatureWood Preservatives
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 ammonium compound and is applied to wood by pressure treatment. Copper and quaternary compounds are effective fungicides and termiticides. Together they provide protection from 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 in NatureWood, copper oxide and quaternary compounds, are dissolved in an alkaline carrier. 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.
Characteristics of the
NatureWood Preserv 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 Weathering Information Freshly treated NatureWood products begin with a familiar greenish color and will over time turn to a light tan/brown color upon exposure to sunlight. As with most outdoor wood products, NatureWood products will eventually fade to gray over time. Lifetime Residential and Agricultural Limited Warranty A Lifetime Residential and Agricultural Limited Warranty is offered on NatureWood products at 0.15, 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 agency is required for the use of the NatureWood trademark and NatureWood Lifetime Residential and Agricultural Limited Warranty. NatureWood preserved wood products are designed for long-term performance in outdoor applications and, therefore, require high quality, corrosion-resistant nails, screws, and hardware. Use hot-dip galvanized, stainless steel, or other fasteners and hardware as recommended by the hardware manufacturer. Direct contact of NatureWood preserved wood with aluminum fasteners is not recommended.* *When using NatureWood preserved wood in close proximity to aluminum products such as aluminum siding, flashing, furniture, and door and window frames, a 1/4" minimum spacing must be allowed between the NatureWood and the aluminum products. An option is to use a polyethylene barrier, with a minimum thickness of 10 mils between the NatureWood preserved wood and the aluminum product to prevent direct contact of the wood and the aluminum. Certain adhesives add extra holding power. For best results, use hot-dipped galvanized, stainless steel, or other fasteners and hardware as recommended by the hardware manufacturer. |
