The HVAC aluminum foil duct board is built using a rigid foam base, and is particularly designed to withstand temperature fluctuations without affecting its quality. Comfort & consistency are the key aspect of this product. Nevertheless, air quality, noise levels and operation efficiency are particularly dependent on its duct system which should be properly planned and installed for the unit to work efficiently.
These rigid foam boards can also be scientifically referred to as the polyurethane insulation panels, they have aluminum foil backings on either sides and are available in panels measurements of between 1.5 and 4 inches thick, these products are also 90% lighter than other conventional metal ductworks available in the market. Generally, polyurethane padding panels are useful in providing insulation for floors, ceilings and walls. Some people also employ them in insulating metal ductwork. The overall insulation value of this material is between R-7.1 and R-8.7 per inch, which is considered one of the greatest insulating values available in the market. R-value refers to the measurement of a material’s resistance to heat loss.
Aluminum ductwork materials should always be insulated in order to increase their efficiency. A vapor-barrier is often required to prevent the buildup of condensation. However, rigid foam boards not only provide the base structure for your ductwork system, but also function as base insulation and vapor barrier material for the underlying material.
Material & Design
Some common materials used together with aluminum during construction are sheet, fiberglass and flexible nonmetallic tubing. The specific type to be used however depends on what that particular job entails, in terms of pricing, performance and versatility. A well-fitted HVAC aluminum foil duct board provides maximum air flow and is also resistant to leakages. The overall design of this product plays an important role in regulating heat and cooling systems, including even distribution of air and maintenance of consistent temperature levels throughout the residence.
Note that ducts which are poorly designed, inadequately installed or poorly sealed can affect temperature levels, indoor air quality and humidity levels within the room. A good ductwork design should therefore be able to distribute air proficiently, with little air loss or temperature fluctuations in-between the panel units. Before beginning any construction work, visit your local building code department to find out more about the regulations for building heating ducts. Ensure that the materials you’re using meet all the necessary building codes, sometimes you may need to present a detailed drawing of the end product’s layout and obtain a permit before starting.
