Wolmanized® Residential Outdoor® Wood: Real wood. Natural beauty. Trusted Name.
A recent addition to the trusted family of Wolmanized® pressure-treated wood products, Wolmanized® Natural Select™ wood combines the natural beauty of real wood with a next-generation, patented new preservative and a lifetime limited warranty against termites and fungal decay. Ideal for decks and a host of backyard projects, Wolmanized® Natural Select™ wood costs less than substitutes such as redwood, cedar or plastic composites, and has many environmental benefits. Natural Select wood is treated with a patented copper-based preservative and an organic fungicide. Proven for more than a decade and across four continents, Natural Select wood is being used for decks, playsets, retaining walls, sill plate and structural members. Copper is the active ingredient in Natural SelectTM wood, protecting against termites and most fungal decay. Protection against copper-tolerant fungi is provided by an organic azole, which has also been used as a fungicide for fruits, peanuts, and other crops. The formulation renders wood useless as a food source for termites and fungi while keeping the wood attractive, clean, and odorless. The preservative in Natural Select wood is not a “restricted use” pesticide and does not meet the definition of hazardous waste. As a result, fewer environmental restrictions apply. No EPA precautions apply to handling the wood, there is no required Consumer Awareness Program (CAP), and California’s Prop 65 labeling is not required. Treating procedures, warranties, and handling procedures are nearly identical Natural Select wood is made like traditional treated wood, in a pressurized cylinder using a closed system that recycles excess preservative for future use and releases no air pollutants nor wastewater. Since it is a patented product, only licensed producers such as Follen, who follow stringent quality control measures, are permitted to manufacture Natural Select wood. Inther treating process, copper azole preservative is pushed into the wood under pressure. It bonds with the wood in a reaction called fixation and is leach resistant. However, some chemical may migrate from preserved wood into surrounding soil over time and may also be dislodged from the wood surface upon contact with skin. On typical 2” material, 90-95% fixation occurs immediately. Fixation of the remaining preservative is time and temperature dependent.  Wolmanized® Residential Outdoor® wood can be used for almost all applications where protection against termites and fungal decay is desired. It is ideal for many residential, commercial and agricultural applications.
Note: At the present time, Wolmanized® Residential Outdoor® wood is not recommended for saltwater applications. Different applications may require different amounts of preservative protection. Below are the standards of the American Wood-Preservers' Association for the two copper azole formulations.
Wolmanized® Residential Outdoor® wood meets requirements of model building codes for many applications, and a code evaluation report has been issued by National Evaluation Service. See NES National Evaluation Report No. 669 for allowable values and/or conditions. Such reports are subject to re-examination, revision, and possible closing of file. The preservative treatment is listed in the standards of the American Wood-Preservers' Association as in two formulations, CBA-A and CA-B. It is suitable for above-ground and ground contact applications (Use Categories UC1, UC2, UC3, UC3B, UC4A, and UC4B). Internationally, it is approved by government and trade agencies throughout Europe and in Australia, New Zealand, and Japan. Hot-dipped galvanized fasteners (meeting ASTM A 153) and connectors (ASTM A 653 Class G185 sheet), or better, are recommended for protection against the moisture often present where treated wood is usually used. For Permanent Wood Foundations, use 304 or 316 stainless steel. Aluminum should not be used in direct contact with this wood. For indoor applications, while galvanized fasteners are preferable, the use of non-galvanized nails or screws of sizes and types approved by the Model Code is acceptable when attaching joists, studs, or other framing to Wolmanized® Residential Outdoor® sill plate, provided the wood will remain dry in service, protected from weather and water. Likewise, the use of standard galvanized strapping, anchor plates, or mild steel anchor bolts 1⁄2” diameter and larger is acceptable for fastening Wolmanized® Residential Outdoor® wood to foundations, provided that the wood will remain dry in service, protected from the weather and water. Additional information on the corrosion of fasteners and connectors used with alternative preservative treated wood. At the present time, there are no EPA-approved precautions similar to the Consumer Safety Information Sheet. We recommend following the same guidelines as for CCA, which are essentially the same guidelines that should be followed when handling untreated wood. For example, wear a dust mask to control inhalation of sawdust, wear goggles to protect eyes from flying particles, wash after working with wood and before eating, and do not burn treated wood. For a complete listing of handling precautions, click here. Wolmanized® Residential Outdoor® wood waste, such as scraps, broken boards, and sawdust, can be disposed of with ordinary trash collection. Neither the wood nor the preservative residues are considered hazardous wastes. If a particular landfill has restrictions against CCA-treated wood, it may accept Residential Outdoor® wood. Treated sawdust and shavings are not recommended for composting, mulching, or animal bedding, and the wood should not be burned except in approved commercial incinerators. Natural Select wood waste, such as scraps, broken boards and sawdust, can be disposed of with ordinary trash collection. Treated wood from commercial or industrial use (e.g., construction sites) may be burned only in commercial or industrial incinerators or boilers in accordance with state and Federal regulations. No maintenance is needed to renew resistance to fungi and termites. Natural Select™ wood has a lifetime limited warranty against these organisms. However, protection is required to maintain the outwood wood's appearance against weather. Sun and rain cycles cause stresses in lumber and result in swelling, shrinking, warping, and cracking.
We at Follen offer KDAT tongue and groove flooring that has been treated with the Natural Select preservative as well as Wolmanized Extra water repellent. The specially formulated Extra water repellent is driven into the wood to provide deep-seated protection against the effects of weather. Surface coatings are helpful, but they can’t match the benefits of pressure-impregnated water repellent. The Extra solution remains in the lumber for the life of the project, reducing dimensional changes. However, sunshine, rain, and foot traffic will break down the water repellency on the wood’s surface. For maximum surface protection, apply a topical water repellent after a year or so and then yearly thereafter. Unlike plastics, steel, and concrete, Natural Select wood's source is a renewable resource grown on managed timberlands. It requires less energy to produce than plastics and offers greater insulation value; and, because of its lighter weight, preserved wood can often be installed with lighter equipment which has less environmental impact. |
