Ductwork Insulation
Prevent heating and cooling loss by insulating the ducts that move air through your home , especially in areas like attics, crawl spaces, or unfinished basements. If you’ve been searching for duct insulation near me or noticing uneven temperatures in certain rooms, this upgrade can make a measurable difference in comfort and energy efficiency.
About This Service
Rim joists are a common weak spot in the building envelope, prone to air leakage, condensation, and pest intrusion. We seal and insulate this area using high-performance spray foam or rigid board, stopping unwanted airflow and protecting your home from moisture.
Sweating ductwork is a big sign that your ducts are not insulated!
This upgrade not only improves comfort and air quality, it also plays a key role in your home’s overall energy efficiency.

Frequently Asked Questions
Is duct insulation part of a larger upgrade?
Often, yes. We combine it with Aeroseal duct sealing, attic insulation, or full home performance upgrades to maximize energy efficiency.
What materials are used?
We use foil-backed fiberglass wrap, duct board, or spray foam insulation, depending on the system’s location, layout, and access.
Where is duct insulation most important?
Attics, crawl spaces, garages, and basements, any area where ducts pass through spaces that aren’t temperature controlled.
Why insulate ductwork?
Insulated ductwork helps keep heated or cooled air at the proper temperature as it travels through unconditioned spaces, saving energy, improving comfort, and supporting HVAC efficiency.
Will this impact airflow?
Yes, in a good way. Proper insulation reduces thermal loss and supports more accurate temperature delivery and airflow balance.
