Duct Insulation: Why You Need It and How to Install It

Duct insulation is a great way to save money on your heating and cooling bills. Ducts located in unconditioned spaces, including attics or basements, will stay at the same temperature as the surrounding space. This means that when you turn on your heater during the winter, it has to work twice as hard because it must first heat up all of these ducts before your house becomes warm. 

Duct insulation can help prevent this from happening by trapping a layer of air between two sheets of fiberglass insulation, which helps keep ducts warmer than without any insulation. Should you have an unfinished basement or attic with no other living spaces above it, you should definitely consider getting duct insulation.

Why Do I Need To Insulate My Ducts?

Ducts are used to move air from one place to another within the home. Duct insulation is a material that is inserted into ductwork systems to reduce heat loss and increase comfort. Without proper duct insulation, you will be spending more to heat up your home, and it will take twice the time for your home to get warm in the winter months.

Duct insulation is a great way to save money on your energy bills and reduce your home’s environmental impact. If you’re not sure if ducts in your home need insulation, there are some easy ways to tell. One good indicator that it’s time for duct insulating is when you see condensation or ice inside the ducts. If you have coils installed in an attic, crawlspace, or basement, then you may also want to consider installing insulation because these areas can get very cold during the winter months.

What Are The Different Methods For Insulating The Duct?

The different ways to insulate your ducts include adding a coat of synthetic insulation to the duct or using reflective material. The most common type of insulating product is a fibrous or cellular glass with an adhesive backing that sticks to ducts. This product reflects heat and can be used for both heating systems and air conditioners.

Pipe wrap, felt paper, foil-faced bubble wrap, foam insulation, and metal duct wrap are some of the other ways that you can insulate your ducts.

What Are The Benefits Of Insulating My Duct?

The benefits of insulation include reducing air infiltration through ducts, which reduces heat loss to outside areas and minimizes drafts from cold-air returns. This is especially important in unconditioned spaces like garages, basements, and attics.

A reduction in duct temperature reduces the amount of heat that must be added to raise air temperatures before it is delivered to conditioned space. This saves energy because less heating or cooling capacity will be needed for a given load of airflow.

Additionally, some people experience symptoms from decreased air quality, such as headaches and fatigue. Duct insulation can help reduce these symptoms by trapping particles that would otherwise be circulated through the duct system.

How Is The Air In My Home Affected By Uninsulated Ducts?

Uninsulated ducts in unconditioned spaces will cause your heater to work harder before your house is warm. In the summer, an uninsulated duct system will cause your air conditioner to work harder before it cools your home.

Duct sealing and insulation can help reduce dust buildup in duct systems by reducing the amount of air leakage around seams on pipes or other joints where sections of ductwork are joined together. This reduces the amount of pollen, dust, and other particles that can circulate through the duct system.

What Type Of Insulation Should I Use For Ducts?

There are several insulation options for insulating your home’s ductwork: open cell or closed cell spray foam; fiberglass batts; reflective foil-faced tape; rock wool blankets; and rigid insulation.

Open-cell or closed-cell spray foam?

The most effective duct insulation because it provides the highest R-value per inch of thickness. Closed-cell is more energy-efficient, but open cells work better for sealing leaks in your home’s duct system. Rigid Insulation: The least expensive option with the lowest R-value per inch. Reflective Foil: The cheapest option with a medium R-Value but does not work well for sealing leaks in ductwork.
