If the air velocity exceeds 1500 fpm (7.6 m/s), perforated metal plates should be used instead of perforated metal sheets to increase the integrity. Apart from the above 4 types of duct insulations, there are other types of duct insulations such as polyurethane, closed-cell (superlon) and pre-fabricated ducts. 0000038997 00000 n Additional reference material and articles of interest to the specifier or contractor. To simply state, if acoustical performance is the main project requirement, like in a school or medical facility for example, then specifiers should consider selecting duct liner. If you have doubt about your HVAC system, kindly contact me to seek clarification. Below is a photo I took years ago. 132 72 0000039076 00000 n 0000009398 00000 n Internal duct insulationproducts are designed primarily to provide acoustic insulation to the ventilation system, but they also contribute to improve the thermal performancedue to the excellent thermalproperties of ISOVER glass wool. The products are non-combustible and do not emit any smoke. 0000053454 00000 n Low noise operation and high efficiency. Below you can see is the inside of an AHU duct. Think about it. Fiberglass, at a minimum, is an acute physical irritant to the skin, eyes, and upper respiratory tract. Duct liner is a product that is used to line the inside of the duct. %PDF-1.4 % HTio0?6($6PpGvW0Yak-m|v!Z%>GRtH8~C}*a ?JvR2-S!: [Ec 0000005689 00000 n When older ducts with fiberglass insulation are damaged or deteriorated, they could potentially expose raw fiberglass fibers into the airstream if they were not manufactured with any protective barrier. Your home is not heated and cooled evenly. Hence, using 1 (25mm) thick fiberglass insulation is sufficient given that you maintain the density of the fiberglass at 2 lb/ft3 (32 kg/m3). We promise satisfaction with our efficient, lasting results. After the primary seal has fully deteriorated, it allows raw fiberglass fibers to be exposed to the airstream. 0000043885 00000 n *h> 0000047737 00000 n Fiberglass duct liner provides thermal insulation for air ducts, preventing the air ducts from losing expensive conditioned air. Duct liners are: Trenchless Innovations can provide you with the full benefits of duct liners. Real-world case studies for challenging construction projects across the US. 0000053172 00000 n To learn more about the different components used in HVAC, purchase and download the HVAC Basics (eBook). Rashes can appear when the fibers become embedded in the outer layer of the skin. Helpful online resources for successful mechanical insulation applications. Polyethylene (PE) is often used to insulate air conditioning ducts as well as exhaust ventilation ducts. g 0000003906 00000 n The primary seal is a black gritty coating on the surface of the duct liner which locks down the fiberglass fibers. Some things that can affect the overall price are: Another thing that can impact the cost is how accessible the air ducts are. 0000011937 00000 n After the air duct system is cleaned, the encapsulate is applied to the air duct surface locking down the fiberglass fibers. link to 3 Types of Compressors in HVAC (Applications & Characteristics), link to Centrifugal Chiller vs Screw Chiller (Chiller Selection Guide), Duct Insulation Guide: How-to, Selection & Thickness.
