Flexible Duct Connectors
Flexible duct connectors are an essential element in many heating and air conditioning systems in residential, commercial, and public buildings. In addition to effectively joining two separate courses of ducts, the flexibility of these connectors allows ductwork to be placed around supporting structures which would prohibit the use of conventional connectors. Flexible ductwork is composed of material which is resistant to heat and corrosion, offers good insulation, and affords a high level of strength and flexibility.
Flexible duct connectors and asbestos
Today, flexible ductwork components are made of materials deemed to be safe for those who install them, as well as those who live and work in buildings which use them. But until the 1978, many flexible ductwork connectors were manufactured using asbestos. Well known and highly regarded as an effective insulator, asbestos fibers are strong and flexible, allowing them to be easily incorporated into the fabrication of many materials used in construction and industrial applications. After countless health studies finally revealed the serious health risks posed by asbestos exposure, the government enacted legislation in 1977 which made use of asbestos in manufacturing illegal in the United States. However, existing supplies were allowed to be used until those stocks were depleted. As a result, the majority of buildings constructed prior to the mid 1980s contain materials which comprise asbestos fibers. Anyone involved in the manufacture of installation of these materials prior to the mid 1980s is at an increased risk for asbestos exposure. But so is anyone who is involve din the renovation or remodeling of any of these buildings. Whenever asbestos-laden materials are disturbed or disrupted in anyway, either through removal, drilling, or other alteration, the material releases tiny asbestos fibers into the air where they may be easily inhaled. Once in the lungs, these fibers can wreak havoc, causing mesothelioma and other asbestos-related cancers and illnesses. Asbestos materials in ductwork applications pose additional risks, since the degraded fibers of aging asbestos can easily become dislodged by passing air currents. These loose fibers can then be transported easily throughout the duct system, affecting anyone who lives or works in the are served by the heating and air conditioning systems.
