Treated wood is used almost identically to ordinary wood. No special preparation is needed unless the wood is going to be painted or installed in an application in which the wood must first be allowed to dry out.




This treated timber avoids the issues associated with an arsenic or chromium based treatment and extends the life of treated timber with minimum health or ecotoxicity issues.

The AWPA, CSA, and ICC-ES credentials mentioned above are recognised nationally and internationally.




IARC has classified untreated hardwood and hardwood/softwood mix wood dust as a Group 1 human carcinogen. The wood dust classification is based primarily on IARC's evaluation of increased risk in the occurrence of adenocarcinomas of the nasal cavities and paranasal sinuses associated with occupational exposures to untreated wood dust.  NTP has classified all untreated wood dust as a carcinogen. However, applying work safety guidelines can reduce the risks, such as wearing a dust mask to control inhalation of sawdust; wearing gloves when working with wood, wearing goggles to protect eyes from flying particles and washing after working with wood and before eating, drinking, toileting or using tobacco products.

The treated timber does not present any additional hazards than what are associated with untreated wood.


There are no known direct impacts on comfort. However, use of treated wood for some applications (e.g., decks, walkways, playsets) can result in people enjoying the outdoors and spending more time outside.

Indoor Environment Quality

IEQ is largely irrelevant since very little of the product is used indoors – it is intended for exposed applications.

Emissions – While it is generally recognized that copper is lost from treated wood in service the rate of loss varies over time. Release rates are highest immediately after installation and then decrease rapidly becoming asymptotic as wood ages. In the context of the long service life of treated wood, short-term releases are negligible because they are limited to a few months (e.g., the first 200 mm of rainfall, with nearly 1,000 mm of annual rainfall in a typical climate) after installation. (source:  Copper Leaching from Treated Wood, American Chemistry Council Copper Task Force, Unpublished Study, 2014).

During a fire, irritating and toxic gases may be generated by thermal decomposition or combustion. Hazardous combustion/decomposition products may include but are not limited to: Carbon monoxide. Carbon dioxide (CO2). Toxic gas. Nitrogen oxides (NOx)., Copper Fumes, Copper metal and Copper oxides. However, the MSDS clearly states that burning treated wood is not allowed. Refer to NFPA 654, Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids, for safe handling.

Physical – In addition to enabling wood to last a long time or resist flames or mold, Wolmanized® Outdoor® Wood has environmental and other advantages associated with the wood itself.  For example, wood: (1) Is a renewable resource grown on managed timberlands. Trees remove carbon dioxide from the atmosphere, thus reducing greenhouse gases.  (2) Requires less energy to produce than alternative building materials; it is made from sunlight and soil nutrients, rather than fossil fuels.  (3) Offers greater insulation value than alternatives.  (4) Is lighter in weight, and can often be installed with lighter equipment which has less environmental impact.


Emissions –The use of tebuconazole or propiconazole in the preservative has associated Risk Phrases stating that it is toxic or very toxic to aquatic organisms. Thus, all downstream users should be notified of possible contamination if and when accidents happen.

Physical –  Not known.


Greenhouse gas (GHG) – There is a low amount of energy required to manufacture wood products compared to alternative materials (steel, concrete). The ability of timber products to store absorbed carbon and emit minimal greenhouse gases during production is a major consideration. The carbon sequestered during the life cycle of timbers has the potential to offset the emissions from the use of the preservative and result in a carbon neutral producer even a carbon sink.

Greenhouse intensity – Information not available.

Wolmanised® E is manufactured in USA.  Transporting the concentrated treatment chemicals is significantly more efficient than transporting finished treated timber. Local impregnation of lumber minimises greenhouse gas emissions associated with transport of timber products.

The use of wood preservatives prolongs the life of timber products thereby reducing pressure on timber resources.

This product assessment relates predominantly to the timber treatment.  Purchase of sustainably sourced and certified timber is a separate issue for the specifier/purchaser.



Resource Efficiency

Preserved wood extends forest resources, allowing one tree to do the work of many. In addition to enabling wood to last a long time, treated wood has all of the environmental and other advantages associated with wood itself. It is a renewable resource grown on managed timberlands. Trees remove carbon dioxide from the atmosphere, thus reducing greenhouse gases.  Wood requires less energy to produce than alternative building materials; it is made from sunlight and soil nutrients, rather than fossil fuels.  It offers greater insulation value than alternatives and is lighter in weight, and can often be installed with lighter equipment which has less environmental impact.

Embodied Fossil Fuel Energy

Embodied energy information for product is not available.

Transport intensity – Product is manufactured in USA and sold in USA and elsewhere. Local manufacture minimises embodied fossil fuel energy associated with international transport of products.

Embodied Water

Copper azole-treated lumber deck consumes 53.00L/functional unit of water (using a 320 square feet (approx 31m2) decking as a functional unit). According to a third-party accredited life cycle report provided by the manufacturer, this product reduces 75.71L/functional unit of water compared to wood plastic composite deck.


The preservative treatment enables ordinary wood species to resist damage from wood-destroying organisms (termites and decay fungi), thus extending its life significantly in exposed applications.


When wood treated with Wolmanized® Outdoor® Wood is dismantled due to deteriorating appearances after years of service, it can still be used for other applications as it is still resistant against termites and fungi decay. Moreover, it can still be effective in other applications where aesthetics are less important, such as in driveway edging, retaining walls, or planter boxes.


Wood is readily repaired with common tools and widely held skills. Boards can be replaced, re-nailed or re-screwed. Decks can be enlarged, railings can be replaced.

Design for Dematerialisation

Not known.

Design for Disassembly

There was no design for disassembly, but wood inherently is fairly easy to take apart.


At the present time, there are no facilities or means for recycling old treated wood. Although the pesticide in treated wood may be toxic to certain organisms, treated wood is accepted for disposal in nearly all lined landfills. Like most other building materials and even old furniture, product should not be burned except in approved incinerators.


Maintenance is dictated by aesthetics; no maintenance is needed for performance. Typical cosmetic maintenance entails cleaning as needed and periodic coating with a water repellent or a stain that contains water repellent. Periodic cleaning can revive the colour of preserved lumber.

Red light comment.

Note: Given that the purpose of the product is to preserve the timber from attack from various types of organisms, some degree of toxicity is required for this product to perform its purpose.

Due to the very limited amount of the above preservative chemicals that are used in product (<or = 0.1% by weight of the board), and the controlled environment in which the preservative is applied, the likelihood of risk to organisms or the environment is low. However, during manufacturing stages, care should be taken when handling or applying the substance, ensuring appropriate safety gear and control over application area meet the highest standards. All of the preservative chemicals are U.S. EPA-registered and their production, shipment, and use are regulated by EPA’s Federal Insecticide, Fungicide and Rodenticide Act. Procedures have been created, evaluated and updated by independent scientists.
