The 1965 Parade of Homes

leave a comment »

The quality on this video is not great, but you can see a method of wall construction using sound-deadening board plus gypsum wall board that was used for the 1965 Parade of Homes in Alabama. As Boomer families grew and entertainment moved inside the home, the building industry played up the concept of the “Quietized” home.

Is Forever Board the future of drywall?

leave a comment »

 

 

Ronald J. Voit sees gypsum boards used everywhere in construction as drywall building material.

But he remains undaunted about bringing a mold-resistant alternative called Forever Board to the market.

“It’s just a matter of getting everybody familiar with the product,” Voit said of his invention.

Buffalo is the hub for his hopes. A few years ago, Voit bought a vacant factory near the Buffalo River in South Buffalo and moved in production equipment he acquired from a defunct plant in Ohio.

Now Voit has launched manufacturing, aiming to get his product used in commercial and residential projects. Voit said he uses a proprietary process to strengthen the chemical bonds in production of his magnesium oxide boards. “I use the Coca-Cola, Kentucky Fried Chicken theory: Nobody knows my secret recipe, not even my investors,” he said.

Shaping The Future with Gypsum Wallboard

leave a comment »

I wish I knew more about this video. I can date it back to 1969, but I think it might be older than that. This is another industrial film from the Gypsum Association, and uses clips that I’ve seen in some of their other videos. There’s a shot of a living room set towards the end of the video that is particularly groovy.

CDC confirms health issues connected to Chinese drywall

leave a comment »

SARASOTA COUNTY, Fla. — For the first time, the federal government confirms that tainted drywall can cause home and health problems, according to a long-awaited report by the Centers for Disease Control….

It’s an issue some are still living with. Many might not even know it. The report also indicates that “not all of the homes contain drywall manufactured in China. Some problem homes contain drywall manufactured in North America and some have drywall with no indication of origin.”

“This isn’t Chinese. This is United States Gypsum.” North Port resident Charles Hummer has turned his home into a laboratory of tainted drywall, researching the effects and how it all came to be. He says his health and home problems are caused by drywall which doesn’t have a foreign label.

He says you have to follow the money. “Knauf brought in all the Chinese drywall. Knauf also owns part of United States Gypsum. Knauf also owns part of National Gypsum. United States Gypsum also owns L&W Supply, which is doing business as Seacoast Supply.”

CDC confirms health issues connected to Chinese drywall – Sarasota News | Mysuncoast.com and ABC 7: Local News.

“Some problem homes contain drywall manufactured in North America” is a little misleading. Designated “problem homes” are based on occupant reports and observation of symptoms and effects such as corroded metal fixtures and “recurrent headaches, irritated and itchy eyes and skin, difficulty breathing, persistent cough, runny nose, sinus infections and congestion, sore throats, frequent nosebleeds, and asthma attacks.” It has not been proven that North American drywall causes any of these symptoms.

In fact, the report goes on to advise, “Based on the limited number of drywall samples tested, exposures to the estimated contaminant levels from drywall samples manufactured in North America in 2009 were below levels of public health concern. These samples were not identified by CPSC as problem drywall.” (My emphasis.) However, some homeowners assert that domestic wallboard causes these problems as well.

As for following the money, Knauf does own part of USG Corporation. National Gypsum is a privately owned company.

The Eye on Housing post links back to the cost survey with detailed breakdowns. Total construction costs for the average home were $246,453. The cost of drywall was $9,376, or 3.8% of the sales price, down from 4.4% in 2011’s survey.

Gypsum Board: Are Our Walls Leaching Toxins? | GreenSpec

with one comment

Domestic manufacturers are quick to point out that gypsum board manufactured in the U.S. has not been linked to indoor air quality problems, but potential leaching of heavy metals and biocides included for mold resistance are among the issues that need to be addressed more thoroughly by the gypsum board industry.

John Friedman: Climate Change: Good for Business?

leave a comment »

From an article about business innovation and climate change:

Synthetic gypsum has been used to make wallboard in the United States for more than 20 years. Electric power plants that burn coal are required to have scrubbers that trap emissions. The result is a very pure synthetic gypsum that is being used to create wallboard. Since 2000, enough gypsum to finish the interior of more than 7 million American homes has come from this waste product.The future belongs to the innovators and the clever and the bold.
