Flexible ducts are used in HVAC systems and can be installed in tight spaces. They can be made of different materials, insulated or uninsulated, and have varying life expectancies. Some are environmentally friendly and fire-resistant, but can be damaged by UV light. Insulated ducts can save energy and prevent bacterial growth. They are usually packaged in 10-meter lengths and can be transported in cartons or plastic bags.
A flexible duct is a special type of duct used in a general HVAC system. One of the benefits of flexible ducting is that it can be installed in tight spaces, where standard ducting could not fit. It can also be used to bend circular or oval parts of a building structure. This can help create an optimal location for the duct system and make energy use more efficient, while also ensuring the air quality in a home or building.
The flexible conduit can be made with different types of materials. Some are laminated with aluminum, which is considered a standard quality substance. Spring steel wire helixes are also often used as a material and generally make the product flexible and durable. Sometimes, polyethylene vapor barriers surround the duct to help with energy savings. Many flexible ducts don’t require any tools for cutting or fastening, which can potentially simplify installation.
The life expectancy of a flexible duct can vary. Most products are designed to last as long as your home. This is a good option, because it means the ducts won’t need to be replaced. General life expectancy usually varies from manufacturer to manufacturer.
Most ducts are manufactured to meet safety standards, such as air quality regulations. Other products point out that they are environmentally friendly. Many manufacturers produce flexible ducts that burn but do not give off dangerous fumes in a fire. Other types of products have been tested to be fire resistant.
Some flexible ducts can be damaged by ultraviolet light. They can become brittle or even break if placed too close to lighting systems. Usually a manufacturer will clearly indicate on the product packaging whether the flexible conduit is susceptible to UV damage.
A flexible conduit can be insulated or uninsulated. This is an important difference, because insulating products can help save energy while helping keep the air clean. Some ducts are thermally insulated with materials such as fiberglass. Products that use fiberglass insulation, however, are not 100% formaldehyde-free, as all of these insulations contain some amount of formaldehyde.
Many flexible ducts are insulated with antibacterial material. This can help prevent the growth of bacteria and other fungi inside the duct, which can have adverse health effects. There are also differences in how flexible ducts are packaged for shipment to users. Most of the products will have a standard size of 10 meters. They can also be packed in cartons or plastic bags. This can be important in cases where flexible ducting needs to be transported and lack of space is feared.
