A Hard-plated, a lack of construction materials from home in the town of developments over the past ten years has been found to break down after only a few years, so that owners and owners of leaks d uncertainty and large roofs and repair bills.
The plywood, called for FRTP flame retardant treated plywood, was in the roofs of one million housing units located east of the Mississippi, the National Association of Home Builders.
Given that problems were discovered for the first time in New Jersey a few years ago, scores of complaints lodged against the decision of policy makers, suppliers and insurers. And as the courts to decide, he is responsible, developers have spent millions to replace the roofs and poor homeowners have begun to demand the holding of a refund.
Contribute to other countries
The plywood was adopted after the fire codes were amended in early 1980’s, “just in time” for the Nationwide Building long boom. Now that the boom is over, concerned about the plywood, a saturated market Townhouse, lower prices and a builder of the rash of bankruptcies.
People in the dispute say that the problem may be related to the legal provisions fury, came on the cost of disposing of asbestos 20 years.
”It is a major problem in New Jersey, and it will probably be in other countries,’’said Marshall Frost, New Jersey, an engineer, as an adviser to the State and a number of parties.
Complaints were in Connecticut, Arkansas, Virginia and Florida, but the direction was from New Jersey, where 45 applications have already been presented to more than $ 100 million damages manufacturers and suppliers of plywood. An early, which cites one of the largest public owners of condominium, Company K. Hovnanian. He continued, on behalf of its 32 New Jersey after a change in the bröckelnden roof of a condominium in Lawrenceville has less than two workers injured.
Weigerte to pay patent rights
Repairs are expensive, and if the owners are now required to ensure that all new homes in New Jersey after 10 years - the only state in the nation of such a law - the most private insurers have until to now refused to pay information on the roofs damaged.
The building Association estimates the minimum cost for the replacement of roofs at $ 2000 per unit, even if the local owners probably think $ 3000 is a minimum value. In the lower estimate of the bill to replace all the duct, to $ 2 billion. The New Jersey Department of Community Affairs, oversees New Jersey’s real estate market, said costs in fixing roofs in this state ranges from $ 30 million to $ 130 million.
The author, according to scientists of the Federal Republic of Department of Agriculture’s Forest Products Laboratory, chemical treatment of wood against-plated with organic and inorganic salts.
The salts that are blackened wood instead of lighting and tank when it is heated, as well as carbon dioxide and water, wet fire.
But the heat has built on the roofs by sunlight - at temperatures as low as 150 degrees Fahrenheit - including the fire to suspend the acid that designers of wood to move only on the temperature of an existing home fire, over 400 Degree. The heat and chemical attack of the cellular structure of wood, weaken.
The wood treaters and suppliers say that the product of sound. It is said that the problem arises only if the wood is not properly installed on the roof and the ground is not enough ventilation.
Request for adequate ventilation
”The poor levels of humidity, there is a problem,’’said John Ferry, secretary-treasurer of the American Wood Preservers Association, one of the defendants in which several complaints. Mit”eine But you do not have sufficient ventilation.”
The manufacturers rejected this argument and argues that the decomposition of wood against-plated begins in the sheath of the surface, under the shingles, and not on the merits, where the breakdown help. Federal investigators first looked at the argument, but the breakdown is postponed, because the disengagement. However, many owners have installed flat roof installations exhaust fans.
Before the plywood was in the early 80’s Town House developments were normally be two metres tall masonry extension of guardrail above the line between the roof of every house. The new owners of plywood allows for the elimination of the ramp by four feet of large parts of plywood on both sides of a wall of fire.
Given that many countries east of the Mississippi, construction and provisions of the Code of fire proposed by Boca, an independent group of engineering which is headquartered in Chicago, each installation subdivision built with roofs plain, located east of the Mississippi since the early 80’s probably contains equipment. Some countries require west of the Mississippi, whose use in certain public buildings.
The wood is not generally used in family homes. It would not recognizable by a Shopper.
