Which is Better Duct Liner or Duct Wrap?
Which is Better Duct Liner or Duct Wrap?
Wrapping and duct lining both have their benefits and drawbacks. However, with careful planning and consideration, either one or both of these options can be a viable option for meeting the needs of an air-handling system. Installers and engineers need to be aware of the differences between these products in order to determine the right material for their application.
Why insulate ductwork?
It is important that you understand why ductwork is insulated. Insulated ducts provide sound control and thermal performance. They also maintain uniform heating and cooling throughout the air-handling system.
What's the purpose of duct liner?
Duct liner can be used to line the inside and outside of a duct. Elastomeric foam is used to line a duct. It provides thermal protection against energy loss and condensation control. It also absorbs sound and dampens vibrations from HVAC noises. You will need insulation that can absorb different sound frequencies. This is measured using a noise reduction coefficient (NRC). Higher NRC values indicate better acoustical performance. Particulate and mold can be a concern because duct lining is located inside the duct as well as in the airstream. Elastomeric foam insulation is non-particulate, and does not release fibers into the atmosphere.
What's the purpose of duct wrap?
Duct liners play an important role in HVAC systems' thermal and acoustical insulation. However, duct wrap serves another purpose. Wrapping a conduit is an option when access to its interior may not be possible. This is especially true when retrofitting an existing mechanical system is required or when renovating an older building. Elastomeric foam wraps the duct to provide excellent protection against energy loss and condensation control. It also provides vibration damping benefits. After the ducts are installed, duct wrap must be applied to the duct. This is because insulation and installation of the ducts requires two steps.
Remember that although one material might be cheaper, the total cost of the project will vary depending on labor costs and how the installation is done. The ducts are ready for installation when the duct liner is applied to them as soon as they have been fabricated. Duct wrap must be applied to the ducts after they have been installed. It is possible to lose out on the savings by using less expensive insulation. Installing and insulating ducts is a two-step procedure. Spiral ducts present unique challenges and special needs. Engineers should consider double-wall insulation as an option to duct wrap or duct liner.
What is a system's requirements?
It is important to choose insulation materials that can withstand the demands of maintaining and changing the system over time. Before preparing a project specification, it is important to consider design and performance as also the objectives of the project owner. It can be difficult to meet all these performance goals in a cost-efficient manner and within a competitive market. GIS insulation is here to help you, no matter what system you choose. We provide all the insulation systems in affordable prices without compromising about their quality.
