This month our newsletter focuses on Copper Azole.
Copper Azole (CA) is indeed a wood preservative used to protect timber against decay, fungi, and termite attacks. This treatment involves impregnating wood with a mixture of copper and an azole compound, typically tebuconazole or propiconazole. Here are some benefits associated with Copper Azole wood treatment.
Wolmanized® Outdoor® Wood made by preserving Douglas fir or hem fir with Wolman® E copper azole, combines the natural beauty of real wood with long-lasting resistance to termite damage and fungal decay. This wood is ideal for decks, retaining walls, fences, picnic tables, planter boxes, walkways, sill plate, structural members and more. At appropriate retention levels, it can be used for above ground, ground contact, and freshwater immersion applications. It is presently not recommended for saltwater immersion.
Wolman® E Copper azole preservative renders the wood undesirable as a food source for termites and fungi.
During the treatment process, preservative is forced into the wood under pressure, where it provides decades of protection. Copper is the primary ingredient, protecting against termites and most fungal decay. Protection against copper-tolerant fungi is provided by the dual azole co-biocide. Some chemical may migrate from preserved wood into surrounding soil and water over time and may also be dislodged from the wood surface upon contact.
Warranty
Wolmanized® lumber is backed by a limited warranty in qualifying residential and agricultural applications. See conradfp.com for the full warranty.
Check the Label
Be sure to check the label and choose the wood necessary for the intended application. See WolmanizedWood.com.
Recommended Hardware
The International Building Code and International Residential Code require metal fasteners in contact with any preservative treated wood to be hot-dipped galvanized material meeting ASTM A 153. Code requirements should be observed. Connectors should be made from galvanized steel sheet conforming to ASTM A 653 Class G185. For Permanent Wood Foundations, use 304 or 316 stainless steel fasteners.
Indoors, and where wood will remain dry in service, corrosion is less likely to occur than outdoors. The model code permits use of standard galvanized strapping or mild steel anchor bolts 1/2” diameter and larger for fastening Wolmanized® wood to foundations.
Maintenance
When dry on its surface, Wolmanized® wood can be stained like ordinary wood, and once dry internally, can be painted. For thorough internal drying, purchase material that has been re-dried after treatment or, after the project has been completed, allow several months of good drying weather prior to painting.
Many light-colored latex paints can be used successfully, following brush-application of an oil-based primer. Primer should not be applied by sprayer, nor should coatings be used if their manufacturer advises against an oil-based primer. Always follow the manufacturer’s directions and take special care in coating end grain, holes, and cuts.
For protection against moisture damage, regular application of a topical water repellent is recommended. Periodic cleaning can revive the color of preserved lumber.
Handling Precautions
Follow guidelines similar to those for handling untreated wood. For example: wear a dust mask to control inhalation of sawdust; wear gloves when working with wood; wear goggles to protect eyes from flying particles; and wash after working with wood and before eating, drinking, toileting, or using tobacco products. Do not use treated wood under circumstances where the preservative may become a component of food or animal feed. For other
precautions, see the website.
Disposal
Wolmanized® wood waste, such as scraps, broken boards, and sawdust, can be disposed of with ordinary trash collection. 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.
Codes and Standards
This wood meets requirements of model building codes; it is listed in standards of the American Wood Protection Association (AWPA) and a code evaluation report (ICC-ES ESR-1721) has been issued.
And It’s Wood
In addition to the preservative treatment that enables wood to last a long time, Wolmanized® wood has all of the environmental and other advantages associated with wood itself. Its source is a renewable and rapidly replenished resource grown on managed timberlands, requiring less energy to produce than alternative building materials and offering greater insulation value. Growing forests and wood products reduce greenhouse gases. Wood offers excellent workability with common construction skills and tools, plus it provides design flexibility and is generally more economical than alternative materials. Furthermore, for many applications, wood is aesthetically preferable.
It is essential to follow proper handling and disposal guidelines for any treated wood to ensure safety and environmental responsibility. Additionally, specific product formulations and regulations may vary, so it’s advisable to consult with local authorities or the wood treatment provider for the most accurate and up-to-date information.
