crawl space duct insulation and the benefits

Improve energy efficiency and indoor air quality today

Air Sealing Crawl Space Ducts

All ducts in the crawl space need to be sealed with mastic. Mastic does not peel away from the joists since it does not shrink as it matures. Ducts must be sealed before insulating them. Your home will immediately get any leaking air from the area surrounding your air ducts if they are not properly sealed and this will float about in the air within your house. 

Benefits of duct insulation

Crawl space duct insulation is one of the most effective ways to improve your home’s energy efficiency, leading to lower energy costs. Installing duct insulation will help keep the home warm in the winter and cool in the summer while also saving the lifespan of your HVAC system because it won’t have to work as hard to hear or cool your home. 

condensation prevention

When crawl space ducts are not insulated, condensation commonly forms on the air conditioner ducts. Condensation then forms as the cold air moves through the heating ducts in a warm crawl space, and this condensation can potentially cause moisture to accumulate in your ducts. Dampness can lead to poor air quality in your house and mold and mildew. 

Energy and cost savings

Ducting is insulated to control temperature by protecting your ducts from the crawl spaces warmth or cold. You will spend less on utility bills if you don’t have to heat or cool the air twice to get your house to a comfortable temperature. Cutting down on energy waste will have a more significant environmental effect. 


Leaky and uninsulated ducts in the crawl space can lead to a substantial loss of energy and money. By wrapping the ducts with insulation, you can create a barrier that prevents heat loss or gain and helps maintain a consistent temperature throughout your home, resulting in lower energy bills. In addition, insulating your ducts can also improve indoor air quality by reducing the likelihood of dust and other contaminants entering your living spaces.

Frequently Asked Questions About duct insulation

Duct insulation is as important as any other insulation. The benefits of duct insulation are that it prevents loss and lowers utility bills, improves air quality by preventing circulation of allergens and contaminants in the crawl space into the home, prevents moisture accumulation on the ductwork which can lead to mold and mildew growth and other moisture-related problems, and will increase the lifespan of your HVAC system.

You can’t use any type of insulation to wrap the ductwork in your crawl space. Different types of insulation for ducts exist, each with their own benefits.

It is essential to hire a professional to wrap your ducts with insulation. It will save you time and ensure proper installation for maximum benefits.
