Shortly after it was posted, Claire Guappone of Osmose contacted me regarding “MCQ Shows Signs of Rapid Decay” and asked if I would like to receive a follow up press release on the matter.

“Sure,” said I. So, here it is.

Consumer Safety and Product Performance of Micronized Copper Technology Confirmed

GRIFFIN, Ga., Feb. 11 — On Feb. 9, 2009 in a negative public relations document apparently intended to scare users of treated wood, Charlotte, NC-based Viance criticized the effectiveness of micronized copper wood preservatives. “Viance is once again attempting to create unfounded concerns about consumer safety and product performance, using statistically insignificant and suspect data,” said Paul Goydan, President of Osmose, Inc.

Extensive laboratory and extended field testing have confirmed the effectiveness of micronized preservatives. Several world renowned scientists have confirmed the strong performance of this technically advanced preservative technology and have published their comprehensive findings, which support the micronized technology’s efficacy in providing wood protection for both above ground and ground contact applications.

So why this unfounded attack by a competitor? An attack based on an insignificant sample of a few posts selected by this competitor — out of the millions of posts in service? One might conclude the competition has not been able to create a viable alternative product to compete with our patent pending technology and the ever-increasing market penetration of the micronized copper preservative systems. Rather than offering similarly advanced technology, they have resorted to needlessly alarming the public.

MicroPro(R) Treated Wood Facts:

  • Over 5 Billion board feet of MicroPro treated wood has been sold since the product introduction in 2006.
  • Over 10 Million 4 x 4 micronized treated wood posts are presently in service and performing.
  • MicroPro copper based preservative systems have been independently tested and evaluated in accordance with AWPA, ASTM and other internationally recognized laboratory and field test procedures.
  • Micronized copper preservative systems are certified by the International Code Council Evaluation Service, Inc. (ICC-ES).
  • Osmose’s micronized technologies have earned the Environmentally Preferable Product (EPP) certification from Scientific Certification Systems (SCS).
  • Osmose provides a Residential and Agricultural Limited Warranty on MicroPro treated wood products.

Bottom Line

Extensive laboratory and field testing has confirmed the effectiveness of micronized preservatives. International experts have confirmed the legitimacy of this technically advanced preservative technology and published their findings in support of it. Billions of board feet of micronized treated lumber are in service and performing. Since the introduction of micronized copper technology, Viance, the only copper based preservative manufacturer that does not have the micronized technology to offer, has waged a desperate campaign against it in an effort to discredit it. Meanwhile, more and more consumers and retailers continue to embrace the environmental and performance benefits offered by our technically advanced micronized products.

Since 1934, Osmose has produced quality, tested, reliable wood preservatives such as MicroPro. We fully stand behind our products and back them with industry leading warranties.

Micronized Copper-Treated Wood is Showing Rapid Decay Raising Concerns for Consumer Safety

CHARLOTTE, N.C., Feb. 9 /PRNewswire/ — Findings on 4×4 posts at residential locations reveal dramatic evidence that wood treated with micronized copper preservative(MCQ(TM)) is decaying more rapidly than anticipated. These decay findings raise serious concerns about the structural integrity and safety of outdoor structures, such as decks and fencing, built with micronized copper preservatives within the last three years.

“We are very concerned about the safety of possibly millions of consumers whose decks and other structures were built with micronized copper-treated wood because the wood may be subject to early failure and possible collapse,” said Steve Ainscough, president and CEO of Viance, a leading provider of wood preservation technologies that refuses to offer micronized copper preservatives due to ongoing concerns about the technology.

Residential Findings in Southeastern U.S. Show Evidence of Significant Decay

Today’s announcement is based on Viance’s in-service findings of decay on 4×4 posts located in multiple residential locations near Atlanta, Georgia and Baton Rouge, Louisiana. Timber Products Inspection (TP), a leading independent and accredited wood products inspection and testing organization in the United States, supervised the identification, extraction and testing of the decaying posts at these locations.

TP’s reports describe numerous posts receiving a rating of “less than sound” on the American Wood Protection Association (AWPA) rating scale. The decaying posts from these multiple subdivisions were rated at “9.5,” “9” and “8” on the AWPA’s scale of 1 to 10. One post removed from the Georgia location was rated a “7,” which the AWPA defines as having moderate to severe attack with 10 to 30% of the cross sectional area subject to decay. A decay rating of 7 or below is considered unserviceable by the building industry. TP verified that the average preservative penetration and retentions for the samples examined met the current retention requirements outlined in the International Code Council Evaluation Service (ICC-ES) requirements for MCQ products. The TP report is available in it’s entirety at Viance’s website; www.Treatedwood.com. Furthermore, TP’s reports indicate that the decay is present in the outside zones of the posts below the ground line, to a depth of nearly one inch on some posts.

According to Lee Gjovik, a widely published independent wood scientist, “Any decay on a post that’s only been in service for less than two years represents a significant amount of unexpected decay. Decay ratings of 9.0 or 9.5 should not occur until after many years of service.”

“Another cause for concern,” explains Ainscough, “is that the decay we’re seeing is below the line of sight where consumers may not be able to see or properly inspect the posts. A post’s strength comes primarily from the outer surface of the post, and it is also in this area that the preservatives are present and must prevent decay. The hidden or buried portion of a post must have preservatives that work and prevent decay or the post and structures will fail.”

These recent decay findings corroborate the results of Viance’s ongoing field tests, which were presented to the lumber and building products industries in the spring of 2008 and can be downloaded in their entirety at www.treatedwood.com.

An Overview Of Today’s Technologies

Micronized copper-treated wood products were first introduced to the marketplace in 2006. The manufacturers of micronized copper preservatives, Osmose(R), Arch(R) Wood Protection and PhibroWood(R), have not submitted any of these products to the AWPA for review or standardization. Micronized copper wood preservatives are sold to U.S. builders and consumers through more than 5,000 lumberyards and some leading national home center chains.

Viance remains committed to providing its customers with high quality, industry standardized preservatives, such as Preserve(R) ACQ(R) and Ecolife(R) Stabilized, Weather-Resistant Wood, and ongoing information, testing and investigations regarding the performance of micronized copper-treated products.

Viance LLC provides an extensive range of advanced wood treatment technologies and services to the global wood treatment industry. With an expertise in wood biocides and wood protection chemicals, Viance provides high-level product support to its customers to provide innovative, advanced solutions that improve the performance and durability of wood and wood products.

Lumber Talk’s Commentary
CCA was a great chemical. It would be nice if its removal from residential use because of its scary-sounding ingredient arsenate could be substantiated with proof that it was actually harmful (not to wish harm to anyone). It would make the idea that we now use inferior products like MCQ a little easier to swallow.

LARAMIE, WY–(Marketwire – January 29, 2009) – Centennial Woods, the Laramie-based company that maintains and reclaims snowfence from the prairies and mountainsides of Wyoming to create its line of interior and exterior specialty wood products for residential and commercial use around the world, announced today that Mountain Living Magazine has completed and officially unveiled its Cordillera, Colorado Natural Dream Home. The year-long design and build journey is exclusively chronicled in the January and February issues of the magazine, along with profiles about the Rocky Mountain region’s top eco-friendly ideas, products and companies, including Centennial Woods. The home is on track to earn the LEED for Homes Gold Certification from the U.S. Green Building Council later this year.

“When we discovered Centennial Woods reclaimed snowfence, we knew we had to incorporate it into the home,” said Margie Hamrick, president of Ecoexistence, Mountain Living’s Natural Dream Home developer. “Using Centennial Woods reclaimed snowfence we created bunk beds, desks and other eco-friendly custom furniture that is beautiful and truly one of a kind.”

“The Natural Dream Home was designed to include reclaimed lumber inside and out,” said Grant Porder, Centennial Woods vice president of customer care. “Mountain Living Magazine, Ecoexistence and Associates Three selected Centennial Woods reclaimed snowfence because of its reputation for delivering gorgeous, regionally reclaimed products with a truly green pedigree. Our collection of specialty wood products are strong and true, and provide a more robust design and aesthetic value than any other reclaimed wood product line in the world.”

Centennial Woods products have been specified and selected for Mountain Living’s Natural Dream Homes two years in a row. Despite abundantly available reclaimed barn wood inventory on the east coast, Centennial Woods reclaimed snowfence also was unanimously preferred by Southern Living magazine’s architects, builders and designers, who used Centennial Woods reclaimed exterior siding for the Southern Living Idea House in Asheville, North Carolina last summer.

About Centennial Woods

Before Centennial Woods began harvesting Wyoming snowfence, older boards were often left on the frame too long and burned or thrown in a landfill when replaced. Centennial Woods discovered its strength and beauty and vowed to rescue and reuse it.

Since 1999, Centennial Woods has been maintaining and harvesting snowfence from the mountainsides and open prairies of Wyoming for second use inside and outside residential and commercial properties. To support its reclamation mission, Centennial Woods has developed an international market for this green Wyoming export. To date, Centennial Woods has reclaimed 5 million linear feet of Wyoming snowfence, the equivalent of 85 miles; keeping more than 9,000 tons of CO2 from being emitted into the atmosphere and saving the state of Wyoming and other entities more than $9 million.

Centennial Woods reclaimed Wyoming snowfence is naturally dried for decades by the Wyoming wind, which produces an intensely beautiful, perfectly dried, strong and true reclaimed board. Centennial Woods is a member of the US Green Building Council (www.usgbc.org) and is proud to be one of Wyoming’s great green products. Learn more on the web at? www.centennialwoods.com.
