Report From Cersaie: Italian Tile Makers Go Retro With Green Style, Design

Italian Tile Makers Go Retro With Green Style, Design

Exports to U.S. markets showing growth as economy slowly recovers.

Bologna, Italy—As design professionals and the tile industry gathered at the international ceramic tile and bathroom fixture show this week, the mood was decidedly upbeat. Why? Italian manufacturers have started to see some economic improvement around the globe as well as in the United States, which is one of Italy’s most important markets.

“On the basis of the figures gathered in the first half of the year, we are expecting to report overall sector growth at the end of the year of between 2.5% and 3.5%,” Confindustria Ceramica Chairman Franco Manfredini said at a press conference this week. “A key role will be played by exports with expected growth of between 3% and 4.5%, corresponding to an increase in turnover of around 4.7 billion euros in 2010. This recovery reflects the improvement in the international economic situation and demonstrates that the downturn reported by the Italian ceramic industry in 2009 was not caused by a lack of competitiveness, but was a direct result of the financial crisis.”

Cersaie, the international exhibition of ceramic tile and bathroom furnishings, is considered one of the tile industry’s most important shows. (The other is Cevisama in Spain). Held this year from Sept. 28 to Oct. 2, 2010, Cersaie is expected to host more than 90,000 attendees who come to see the the latest products that will be hitting design showrooms across North America this year or next.

Like other nations, Italy, which exports about 70% of its products, saw slowed growth as the global recession hampered demand for and sales of its products. But now with renewed confidence that good times are ahead, the country’s manufacturers are expressing renewed optimism with a bold looks, radical new textures, recycled-content products, and innovative offerings that incorporate features such as solar technology.

“On the style front, interesting cutouts, lace, oversized flowers, skinny stripes, and mid-century modern will make their way to the tile runway,” says a trend report from Novita Communications, the Italian tile industry’s PR representative in the United States. “In line with the times, visitors can expect to see a bounty of organic influences ranging from rustic wood looks to natural stone. And who can forget about green design and technological innovation? New slim formats are guaranteed to make a big impact on the A&D community.”

Chinese Drywall Update: Medical Fears Persist

Thursday, September 9th, 2010

Up to now, major court cases in the ongoing Chinese-made drywall situation have not dealt with any medical or health-related claims. But health issues are sure to come up in court eventually; and in the mean time, fears about possible health effects of the defective material are likely to impact the market value of affected housing — even after all the bad drywall has been removed and replaced with U.S.-made material.

The past month has seen a handful of news items about drywall-related health fears. In one case, the U.S. Army is looking into the possibility that drywall may have contributed to the death of an infant child at Fort Bragg, N.C., according to Raleigh-Durham television station WTVD (“Fort Bragg investigating infant deaths”). Army investigators are examining ten infant deaths in Fort Bragg base housing, all classified as “sudden infant death syndrome” (SIDS) fatalities, and are trying to determine whether any aspect of base housing may have been a contributing factor in the deaths. Parents of three of the infants told the station that they believe Chinese drywall may have been to blame. Specialist Nathaniel Duke, father of one victim, said the Army gave him several different test reports: “One shows two pieces of drywall from their home which tested positive for Chinese drywall – giving off gases at levels higher than a positive control sample.” But a different test, for elemental sulfur within the actual board, came back within normal limits, the station reports (“New information in Bragg baby deaths”).

In South Florida, meanwhile, physician Kaye H. Kilburn, whose California firmNeuro-Test Inc. specializes in “chemical disorders,” says he suspects the drywall emissions of causing premature aging in occupants of the home, reports Tampa Bay Online (“Physician links Chinese drywall, premature aging,” by Sherri Lonon). Dr. Kilburn toured the Tampa area and talked with residents of contaminated homes at the invitation the Greater Sun City Center Contaminated Drywall Coordinating Group, an advocacy organization that contracted with Kilburn to conduct a health survey “to demonstrate the need for government intervention and epidemiological testing on residents in contaminated environments,” according to Tampa Bay Online.

According to the report, “ ‘This is premature aging,’ Kilburn said after touring two homes in Sun City Center and listening to resident complaints. ‘This is a death-causing problem.’ According to Kilburn, the lack of response is often caused by financial motivations and an unwillingness on the part of government officials to delve into issues.’ “

But there is wide uncertainty within the medical field about the health effects of Chinese drywall — one reason why Judge Eldon Fallon, who is overseeing combined federal litigation of drywall-related cases, has deferred taking up any health-related lawsuits. Under the so-called “Daubert standard” for expert witness testimony in federal court, juries aren’t expected to assess competing “hired-gun” testimony — instead, judges are

tasked as “gatekeepers” of expert claims, and must determine whether a witness reflects the broadly accepted science in his field before allowing a jury to hear the evidence. Assertions like Dr. Kilburn’s typically are not admitted as court testimony, unless they represent a broad consensus within the expert’s field — particularly if the expert earns significant income from testifying in high-profile cases, or appears to display a personal bias. (In his website bio page, Kilburn is quite frank about his emotional involvement with his message about chemical injuries — a personal stance which may endear him to victims of pollution, but could throw his testimony into question when a judge, not a jury, is evaluating his opinion’s scientific basis.)

With or without a mainstream scientific basis, however, even the claim of a health problem can affect the market value of a property — and “stigma” that affects property values is an expert field of research in its own right. That’s a factor that could come into play in cases such as the Williamsburg, Va., rental development known as Wyndham Plantation. In that housing area, the owner, H. R. “Dick” Ashe, says he has replaced all the offending drywall and has test data showing that the homes are now free of contamination, reported the Newport News Daily Press (“Controversy brewing with renters over presence of Chinese drywall in homes,” by Joe Lawlor). “But renter Kianna Hart and former renter Cheryl Radcliff said they became sick from the air inside their 2,100-square-foot townhomes after they moved in late last year,” reports the paper. “Hart, who is still living in Wyndham Plantation, said she and her children are constantly sick, and she’s blaming the drywall gases.”

Proving a link between vague symptoms like cough, wheezing, runny nose, or itchy eyes — which can also be caused by a wide range of allergies to anything from pollen to dust mite droppings — is difficult in any particular case. But even the rumor of contamination and health effects could be enough to affect the value of a rental property, or an owner-occupied home for sale.

“Stigma,” defined as a loss of value that persists even after a defective dwelling has been fixed, is the specialty of experts like John A. Kilpatrick, Ph.D., of the Seattle firm Greenfield Advisors. In a 2009 presentation at a conference about Chinese drywall, Kilpatrick explained that even without health issues, homes with construction defects can suffer a loss of economic value that persists even after repairs are accomplished.

“The concept of stigma arose in the 1980s,” explained Kilpatrick, “when practicing appraisers observed that the decline in the market value of an impacted property was consistently greater than the engineering costs anticipated to remediate that property. In the 1990s, we also found that properties impacted by construction defects were similarly affected by stigma. For example, we worked on many of the synthetic stucco cases and found that even after affected homes had been re-clad by other siding materials, there was still a statistically and economically significant negative market impact.”

In a chapter of the book When Bad Things Happen to Good Property, by Robert A. Simons (Environmental Law Institute, 2006), Kilpatrick lists a set of criteria that are typical of situations where stigma can dog a property:

1. Responsibility — Is someone or some company specifically shouldering the blame?
2. Exposure — Has there been a risk amplification, such as in the media?
3. Disruption — Does the contamination affect daily lives?
4. Concealability — Is the risk hidden?
5. Aesthetic effect — Can the contamination be seen, felt, or smelled?
6. Prognosis — Will the contamination be cleaned up in the near future?
7. Peril — Is there a health risk?
8. Fear — What is the general concern level associated with this contamination?
9. Involuntary — Are the property owners themselves innocent in this contamination?

Plainly, if these are the signposts for likely stigma to attach to a property, Chinese drywall seems to fit the bill.

But the problem is not merely subjective, explained Kilpatrick in his 2009 presentation, because even if a home is repaired, lasting effects of the contamination or of the repair itself could raise the long-term financial cost of owning the house. “Simple remediation of the obvious problem will frequently leave secondary issues which can’t be addressed so simply,” he said. “For example, when we worked on moisture intrusion cases, we found that remediation may include replacement of windows, or seals, or some other quick fixes to stop the leak and remediate the obviously damaged parts of the dwelling. But the presence of the increased moisture itself for a period of time often causes damage to the hidden structural members, such as studs, joists, and sills, which can’t be replaced without tearing the whole house down. We are still learning about the residual damages from chinese drywall, and from an appraisal perspective, we want to know what sort of hidden residual damage remains, after a remediation is concluded.”

In some cases, said Kilpatrick, the combination of costs and value impairment could wipe out the whole value of a building. “There are certainly circumstances in which the remediation costs, the loss of use and enjoyment, and the loss of marketability, as well as the increased costs of ownership, all taken together, actually exceed the unimpaired market value of the home,” he said.

It’s unlikely that repaired houses will quickly catch up with the value of unaffected houses nearby, said Kilpatrick. In a neighborhood with appreciation rates of 5% a year, he said, a house that suffered a 30% or 40% loss of value from stigma would have to appreciate at 10% a year in order to catch up over a 10-year period — and that’s without considering any lingering claims about health effects. So for owners of affected houses, it’s likely that remediation will not fully solve their problem — and that even after the house is “fixed,” the house won’t really be fixed.

Chinese Drywall Manufacturer Settles Beazer Homes Lawsuit

Wednesday, May 19th, 2010

Knauf Plasterboard Tianjin (KPT), one manufacturer of high sulfur-emitting Chinese drywall that has corroded metals in homes, has settled a lawsuit brought against it by Beazer Homes USA.

“In an effort to assist with Chinese drywall remediation efforts, KPT has reached a joint settlement with Beazer Homes that used KPT drywall to construct some of its homes in Florida,” said Don Hayden, principal of Baker & McKenzie, which is representing  KPT, in a prepared statement.

No details about the settlement terms have been released.

Beazer executives would not comment on a settlement. The company’s most recent quarterly filing with the U.S. Securities and Exchange Commission said the company found tainted drywall in less than 50 of its homes built in Southwest Florida. Its remediation that began last fall involves ripping out all the drywall as well as electrical systems and other components that might have been corroded by the sulfuric gases.

Beazer isn’t the only builder KPT is negotiating with on settlements. Knauf’s attorney’s release said it has been “seeking a reasonable solution to repair homes built with KPT drywall” with other builders as well in recent weeks.

“The settlement with Beazer is part of KPT’s efforts to get this issue behind them and move forward,” the release stated. “It shows that a solution is possible when there is agreement on reasonable repair costs.”

The settlement follows two recent rulings by federal judge Eldon Fallon, who is hearing hundreds of faulty drywall lawsuits from across the country in his New Orleans courtroom. Fallon has ordered Knauf not only to pay for the replacement of drywall but for the costs of replacing electrical systems as well as some plumbing fixtures, heating and air-conditioning units, and appliances.

Knauf’s attorney Kerry Miller told the Wall Street Journal that Knauf is considering appealing Fallon’s ruling. Knauf has contended that removing the drywall and scrubbing corrosion off the home’s metal parts should be enough to fix the problem.

“Judge Fallon told [Knauf] in no uncertain terms by entering a judgment that you, Knauf, are liable, and here’s what you’re liable for, here’s what’s necessary to fix these homes, and it wasn’t vague in the slightest,” said Allison Grant, a Boca Raton, Fla.-based attorney who specializes in Chinese drywall cases and whose own home was built with defective drywall.

Grant said it makes sense that Knauf would attempt to settle claims with builders who have already resolved their home buyers’ drywall issues and whose buyers have already signed releases from further claims. “It’s just paying them back for whatever their out-of-pocket expenses are.”

But making the builders whole solves only one piece of the problem, said Grant. There are other homeowners whose builders have done nothing to help remediate their drywall problems.

“It’s a very small piece, but it’s positive because at least for my clients, it means Knauf is willing to do something,” Grant said.

Building Product Prices on the Rise

Wednesday, April 21st, 2010

Although home prices continue to fall and sales of new and existing homes are up only slightly this year, manufacturers are ratcheting up prices of building products and materials, according to industry analyst Ivy Zellman.

“Wallboard, concrete, and lumber are all going up,” Zellman told several hundred people attending an Urban Land Institute conference in Washington, D.C., Tuesday. Zellman has been a home building and building products equity research analyst since 1992. “Building product manufacturers are pushing hard and homeowners are going to feel the squeeze.”

Zellman said that four large manufacturers that she surveyed recently but declined to name are making 20% profit margins, although sales of existing and new homes are at their lowest levels in decades. She said that even though manufacturers have “lots of capacity,” she expected prices to continue to rise as the housing industry recovers from the recession. – Jean Dimeo

Feds: Rip Out Problem Chinese Drywall

Wednesday, April 7th, 2010

The government isn’t quite done with its scientific investigation of metal-corroding, sulfuric-smelling Chinese-made drywall, but investigators say they know enough to recommend that the troublesome drywall, along with all the home’s electrical components, smoke and carbon dioxide alarms, and gas supply lines, should be ripped out and replaced

“Taking these steps should help eliminate both the source of the problem drywall and corrosion-damaged components that might cause a safety problem in the home,” said HUD and the U.S. Consumer Product Safety Commission said in an April 2 joint statement announcing the recommendations.

That doesn’t mean that there aren’t other ways to fix the problems, investigators said. “Less extensive or costly remediation methods may ultimately prove effective, but at present the task force lacks a scientific basis to evaluate those methods.”

The “interim guidance” was offered before the scientific investigation was officially finished because many homeowners with the problem drywall are anxious to correct the situation, but have been unsure about how to fix their houses.

It’s been a little longer than a year since the problems of sulfur-emitting Chinese drywall emerged. Homeowners began complaining of metals corroding in their homes, air-conditioning coils failing prematurely, and caustic smells that many said caused health problems. Now more than 3,000 homeowners from 37 states plus the District of Columbia, American Samoa, and Puerto Rico have reported having faulty drywall to the government. The majority of the complaints (59%) have come from Florida, followed by Louisiana (20%).

The investigating agencies have yet to make any pronouncements related to health concerns related to the Chinese drywall. In addition to noting a “rotten egg” smell inside their houses, consumers have reported irritated and itchy eyes and skin, difficulty breathing, persistent coughs, bloody noses, runny noses, recurrent headaches, sinus infections, and asthma attacks.

But the investigation has determined that the Chinese drywall imported during the housing boom and post-Katrina does emit more sulfur than drywall from North America and that the those sulfuric emissions are high enough to cause metals, including air-conditioning coils, to corrode.

Thirty samples of drywall, including some imported from China in 2005/2006 during the peak of the building boom, as well as drywall made in North America, were put in small “chambers” where their emissions could be measured. The top 10 sulfur-emitting samples were of Chinese origin, and some of the Chinese samples emitted hydrogen sulfide at a rate that was 100 times higher than the non-Chinese samples. (Hydrogen sulfide corrodes metals.)

“The patterns of reactive sulfur compounds emitted from drywall samples show a clear distinction between the Chinese drywall samples … and the North American drywall samples, except for two Chinese samples that have similarities to the North American emission profile,” according to the report. Some drywall imported from China in 2009 showed markedly lower levels of sulfur emissions.

The agencies did note that its sample size was small, that it was testing unpainted drywall versus painted drywall in homes, and that its models on the impact of the drywall in homes ware based on estimates.

The studies did debunk one theory that Chinese drywall emitted more sulfur compounds because it contained bacteria that produce sulfur as a metabolic by-product. A sampling of 10 drywall samples showed no apparent difference in sulfur-reducing bacteria in either the paper or gypsum core samples between imported Chinese drywall and American drywall, according to the government.

Other parts of the home may have been corroded by the bad drywall, but don’t necessarily need to be replaced, according to the government, because they don’t pose safety problems. These include copper plumbing pipes and HVAC evaporator coils.

Finally, the guidance says there’s no scientific basis to believe that studs, flooring, or cabinets need to be replaced. While the government recommends that all drywall debris and dust needs to be removed from homes, it also says there’s no evidence that HEPA vacuums and ventilators need to be used during the replacement.

More test results assessing the long-term effects of problem drywall on the safe operation of electrical components, gas distribution lines, fire safety, and HVAC components is expected to be finished this summer.

While the government’s remediation guidelines are clear, the question of who is financially responsible for the cost of the fixes is not. Some home builders, such as Lennar, have voluntarily replaced the drywall in its affected homes and then are suing their suppliers. Others have reserved millions toward remediation. In the meantime, insurance companies are citing exclusion clauses in an effort to avoid paying claims, and lawsuits have begun to pile up, with several in courts now.

House Minority Leader Asks EPA To Revisit Lead Rule

Tuesday, April 6th, 2010

House Minority Leader John Boehner has urged the Environmental Protection Agency (EPA) administrator to look anew at a soon-to-be-enacted EPA rule designed to control the spread of dust from lead-based paint when old homes are renovated. But the Ohio Republican stopped short of requesting a delay in the rule’s April 22 enforcement date.

“At a time when the economy is seriously deflated and the national unemployment rate is looming near 10%, our nation cannot afford to further distress businesses and families by mandating these particular policies,” Boehner wrote in his March 31 letter to EPA administrator Lisa Jackson. “I strongly urge you to consider re-visiting this issue to determine how to protect consumers from the hazards of lead-based paint without increasing costs and harming businesses and consumers.”

With his letter, Boehner joined a growing group of Congressmen concerned about the EPA’s Lead: Renovation, Repair and Painting (LRRP) rule. It requires contractors performing renovation, repair and painting projects that disturb lead-based paint in homes, child care facilities, and schools built before 1978 to be certified and follow specific work practices to prevent lead contamination. (See EPA fact sheet.) Ignoring the new rules could lead to fines of tens of thousands of dollars per day.

Organizations such as the National Lumber & Building Material Dealers Association (NLBMDA) want to see the rule’s enactment date delayed, arguing that the nation lacks enough certified remodelers, much less enough trainers to do the certifying, for LRRP to be successful. They also note that the April 22 launch date comes at a time when the Obama administration has been promoting legislation designed to create jobs by providing tax benefits for energy retrofit projects in existing homes. It’s presumed LRRP would make it near-impossible for such work to take place in pre-1978 homes anytime soon.

Despite those calls for delays, most congressional reaction to the lobbying has produced more subtle suggestions. On March 25, for instance,10 senators urged the federal Office of Management and Budget (OMB) to help make certain that it will be possible for Americans to comply with LRRP. But the senators’ list of suggestions put delay at the end of possible choices (story).

Similarly, Boehner said in his letter that he was concerned the rule “will have unintended and far-reaching consequences.”

“This new rule creates cumbersome mandates, compliance costs and penalties, and it will hinder energy efficiency improvements and hurt job creation in the U.S.,” Boehner continued. “… These additional mandates, costs, and stringent penalties are estimated to double the cost to businesses–which would then be passed onto the consumer. Many small contractors will not be able to compete with their competitors, or will simply not be able to take the risk of making a mistake, and will lose their jobs. Furthermore, many homeowners will not be able to afford much needed energy efficient improvements. As this rule only applies to homes built in 1978 or before, it is undeniable these are the homes that would be prime candidates to benefit from energy efficient improvements.”

Chinese Drywall Update: Builders Burdened by Repair Costs

Monday, March 15th, 2010

Legal action continues in the case of defective imported Chinese-made drywall installed in thousands of homes in Florida, Louisiana, Virginia, and other states. The second of several “bellwether” test trials will begin on March 15 in the Louisiana federal courtroom of Judge Eldon Fallon, where cases have been consolidated into a “multi-district litigation” (MDL-2047) proceeding.

One interesting wrinkle in the upcoming set of cases is whether insurance companies will be held accountable to defray the costs incurred by builders who have been sued by homeowners over the bad drywall. Some insurers have fallen back on a so-called “pollution exclusion” policy clause to avoid paying claims, although the applicability of that exclusion has been questioned. Louisiana attorney Scott Wolfe discussed the pollution exclusion on his Chinese drywall blog in April, 2009.

In any case, builders may find relief elsewhere. As legal experts point out, even when a builder’s own liability policy has loopholes that limit coverage, builders may be covered by an insurance policy carried by one of their subcontractors — in this case, the drywall sub. And even if the subcontractor is a small company, or has actually gone out of business, the sub’s insurance policy could represent a deep pocket. It’s standard practice for builders to require subcontractors to carry policies that include the builder as a “named insured” — and sometimes, the subcontractor liability policies have fewer exclusions and looser coverage limits than the builder’s own policy has.

Expert bankruptcy attorney Sandy Esserman, from the Dallas law firm Stutzman, Bromberg, Esserman & Plifka, told a New Orleans legal conference in summer of 2009, “Subcontractors are not big targets. They’re not big, fat, juicy companies — they are usually small operations. And even if they’re big operations, they’re low-margin. So why in the world would we ever sue a contractor? Well, let me tell you, some of my clients have made the most money suing contractors. Why? Insurance.”

That legal tactic, however, opens a new can of worms. The legal issues of who is covered by which insurance policies, how coverage limits are defined, and whether limitations such as the so-called “pollution exclusion” are applicable, are questions that have to be thrashed out under state law, not federal law. And that brings up a whole other complicated legal issue called “choice of law” — will the policy be interpreted under the law of the state where the home was built, the law of the state where the builder has its headquarters, or the law of the state where the insurance company resides? Attorney Stephen Mysliwiec of the Washington law firm DLA Piper told the 2009 New Orleans conference, “Different states take different views of the pollution exclusion [and other coverage limitations]. So I think the name of the game in insurance coverage litigation will not be so much the substantive terms of the policy. It will be in persuading whatever court the insurance coverage suit is pending in to apply the law of the state which favors your side.”

The choice-of-law question itself is an issue that is typically decided in — you guessed it — a state court. But in the Chinese drywall MDL, that question will now come before Judge Fallon, a Federal judge. That’s because Taylor Woodrow Homes, which has already settled suits with several Florida homeowners and has carried out gut-and-replace remediation on some houses, is now suing the Scottsdale Insurance Company, the insurer for Taylor Woodrow’s drywall sub on the houses, NuWay Drywall, LLC. And the Taylor Woodrow case has been pulled into Fallon’s Louisiana MDL. The Bradenton (Florida) Herald has that story (“Lawsuits over defective Chinese drywall heading to trial,” by Duane Marsteller); also available online is Taylor Woodrow’s complaint in the case.

Judge Fallon is likely to attempt to solve the “choice of law” riddle in a way that can be applied across every similar case. In theory, Fallon could even choose to apply a body of law from a state where none of the parties reside or do business, simply for the court’s convenience. So his decision in the Taylor Woodrow example may set a precedent that enables builders to turn to the insurers of their drywall subs in any case where the sub carries strong insurance — and at least to know what rule book everyone has to play by.

Many smaller builders would welcome any help they can get with handling the mountain of drywall claims. While big, well-funded builders such as Lennar and Beazer have been tearing out and removing drywall on their own nickel, some smaller builders say they can’t afford to do that. Bradenton, Florida-based Medallion Homes, for example, says that the company will go bankrupt if it tries to repair homes without help, according to the Sarasota Herald-Tribune (“Drywall fix could spell bankruptcy,” by Aaron Kessler). Alan Tannenbaum, an attorney for Medallion, told the Herald-Tribune that with its back against a financial wall, the builder was trying to get compensation from its insurance company, its subcontractors, and the subs’ insurance carriers, before attempting any repair.

Meanwhile, the extent of repairs that should be required is itself still an open question — and one that is also under consideration in Judge Fallon’s courtroom. In a puzzle for builders, the two companies who have been proactive in repairing homes — and who have also testified in the federal court — have offered different views about the appropriate repair protocol. As the Sarasota Herald-Tribune points out, this leaves questions about whether repairs already carried out by builders were sufficient, or may have to be re-done (“Drywall evidence presents dilemma for Lennar Corp.,” by Aaron Kessler).

Lennar, for example, has carried out numerous gut-and-replace jobs in which only exposed copper wiring was replaced — wiring under insulation was assumed to be undamaged. But Beazer testified in last month’s federal trial that even insulated wiring would sometimes be corroded by off-gassing from the drywall.

Writes the Herald-Tribune, “A fundamental question remains: What about those early homes in Heritage Harbour and elsewhere where the wiring was left behind? If that wiring is now known to be affected, representing a serious safety hazard, what will be done? Lennar did not respond to questions from the Herald-Tribune on these issues.”

Beazer has also gone a step further than Lennar in cleaning homes after stripping the drywall: Lennar has so far chosen only to vacuum the houses, but witnesses for Beazer told the court that offensive odors can only be eliminated by power-washing or wet-wiping as well as vacuuming. For now, reports the Herald-Tribune, Lennar appears to be sticking to its original method and relying on vaccuming to remove drywall residues.

Ultimately, Judge Fallon will be the one to rule on the extent of remediation that homeowners are entitled to. And when the question of insurance coverage is raised, it will also fall to Fallon to decide whether builders’ insurance companies — and their subcontractors’ insurers — will be required to pony up the funds to make it so.

Pure Sulfur May Be Culprit in Chinese Drywall Problem

Wednesday, November 18th, 2009

Scientists addressing an early November conference in Tampa, Fla., on defective Chinese drywall have offered a more detailed explanation of why the material produces gases that corrode copper elements in buildings, such as wiring and air conditioner coils. According to reporters who attended the “Technical Symposium on Corrosive Imported Drywall,” a $300-a-head event sponsored by the University of Florida, a leading investigator into the problem says the gas releases can be traced directly to the presence of pure sulfur in the panels.

The Sarasota Herald Tribune says that toxicologist Tom Gauthier of the firm Environ International, hired to study the problem by builder Lennar Homes, has found that the elemental sulfur in the panels reacts with naturally-occurring carbon monoxide in the ambient air to form carbonyl sulfide. The carbonyl sulfide then reacts with moisture and air to produce hydrogen sulfide and carbon disulfide. All three gases have been detected in test chambers and in homes containing the Chinese drywall. And according to Gauthier, Environ was able to stimulate a much faster release of the offending gases by placing the drywall in a chamber rich in carbon monoxide.

Government scientists lag behind Environ’s investigators and other outside researchers, notes the Herald Tribune (“Federal scientists trail others on drywall,” by Aaron Kessler). Consumer Product Safety Commission (CPSC) scientists in a report last month, the paper notes, “were not yet even able to state there was an association between the tainted drywall and the corrosion of copper wires, pipes, air conditioning coils, and other metal components” – even though “Florida, along with a host of private consultants, has long since determined that there is a strong association between the drywall and corrosion.”

Tom Gauthier’s results were corroborated by Michael Tuday, research and development director of California-based Columbia Analytical Services, Inc., and Zdenek Hejzlar, an expert in the environmental and toxic health fields with the Fort Myers office of Engineering Systems Inc., reports the Fort Myers News-Press (“Blame sulfur for drywall woes, experts say,” by Mary Wozniak). “The three scientists, in separate presentations, confirmed that the sulfur interacts with indoor air and other agents, like carbon monoxide, to cause different sulfur compounds to be emitted from the drywall in low amounts. It is enough to cause the drywall’s corrosive effect on air conditioning coils and other metal items in the home, they said.”

The sulfur explanation has the virtue of simplicity – unlike a competing theory that casts suspicion on a possible microbial source of the gas releases. “Some labs say Chinese drywall contains significant amounts of sulfate-reducing bacteria,” reports the Palm Beach Post (“Bacteria, chemical reaction debated as roots of drywall problem,” by Allison Ross). But “the bacteria theory needs a lot of work,” said Florida Department of Health toxicologist David Krause, pointing out that while the drywall may contain bacteria, no connection has yet been established between the bacteria and the sulfuric emissions. On the other hand, if carbon monoxide is the limiting element in the formation of carbonyl sulfide, then according to basic chemistry it would make sense that gases are emitted at a steady rate until most of the sulfur in the material is consumed – subject only to the continued availability of carbon monoxide in the ambient air.

Environ scientists also told the conference that in their view, removing the bad drywall and replacing it with fresh, sulfur-free drywall should eliminate the problem, according to the Sun Sentinel paper (“Rip out Chinese drywall and start over, scientist advises,” by Paul Owens). James Poole, an industrial hygienist with the firm, said, “If you remove it, clean up the debris, ventilate the home and rebuild, there’s no reason you can’t expect success.”

Lennar Homes, which has torn out and replaced the defective drywall in dozens of homes already, refused to comment, the Sun Sentinel reports. But Heather Keith, a lawyer for GL homes, which has replaced drywall in at least 20 units, told the paper that customers were “happy” with the fix, saying, “There are no reported or ongoing health or odor issues. I’d be surprised if the scientific community would say that the extensive repair that involves the complete removal of the interiors of a house is premature or insufficient.” –Ted Cushman

How Many Tiles Does It Take to Make A Giant Panda?

Thursday, September 10th, 2009

hakatai-panda-expr-mural-21That was my first reaction when I saw this image of a tile mural recently completed on the exterior of a Panda Express restaurant in Rosemead, Calif. The 490-square-foot mural was created with 3/4-inch-by-3/4-inch Hakatai Classic series glass tiles on 1.17-square-foot mesh-backed sheets. This equates to a whopping 88,200 individual tiles, Hakatai reps report.

hakatai-panda-expr-mural-cl1While the panda application is larger than most residential builders would need to undertake, it’s a good example of the possibilities of Hakatai’s custom mural program, which  can be used to bring a one-of-a-kind touch to a custom home, including walls, floor medallions, and pools. Murals of practically any size can be ordered fairly easily via the manufacturer’s Web site; builders submit CAD drawings or an image, along with dimensions and location details, and Hakatai will generate a mock-up with color and installation guidelines needed to create the design, along with a price quote. Mesh-backed tiles come numbered for layout.

Versatex Presents New Cellular PVC Products and Delivery Systems

Versatex met with Hanley Wood editors today to discuss new products and delivery systems for its cellular PVC products.

Due for release in 2010 are a notched fascia board and a notched rake/soffit board that can integrate with the company’s Stealth beadboard.

Also under development is a nail hole filler specifically designed for its system, and the company is testing a new inorganic filler that may cut its products’ thermal expansion and contraction by 30 percent.

Beyond just products, the firm stressed its value-added services for dealers, particularly helpful during the down market. For example, dealers and distributors can order products in a “mixed nuts” unit, a factory-packaged board of cellular PVC that can be cut into different standard widths. This saves companies money, because they can buy small quantities of each size, but at a unit price. Additionally, Versatex cuts- and prices-to-length; offers lead times of less than a week; and allows buyers to order less-than-truckload quantities.–Victoria Markovitz
