Leaky ducts are the #1 source of energy waste in buildings!
Learn how to increase energy efficiency while improving comfort and indoor air quality.






Sealing your ducts from the inside out!




ELIMINATE LEAKS
The AEROSEAL duct sealing system seals duct leaks up to 5/8”, and as fine as a human hair.
SAFE & CERTIFIED
AEROSEAL’s Waterborne acrylic seal is UL, FDA, and ASTM certified, along with the coveted GreenGuard Gold certification for LEED and Passive House buildings.
QUICK & NON-DISRUPTIVE
Unlike manual ceiling methods that require extensive disassembly of ceilings and walls, AEROSEAL’s pressurize and spray system can be completed in a third of the time with no business interruptions or disruption to the building.

AIRTIGHT DUCTS. AIRTIGHT RETURNS
20-45% AIRFLOW INCREASE
Eliminating duct leakage allows you to recuperate conditioned air that is being lost above the ceiling, the walls and mechanical spaces that do not require ventilation.
40% REDUCTION IN HVAC DEMAND
60% of a building’s HVAC energy goes to its fans. Studies show reducing duct leakage by 15% drops fan requirements by 40% or more.
12-`15% ENERGY COST REDUCTION
18-25% CARBON EMISSION REDUCTION
Eliminating airduct leakage increases the efficiency of the HVAC fans, effectively lowering energy costs and excess ventilation loads.
Sealing ductwork allows you to lower your heating load demands. Lowering your natural gas consumption translates to an immediate reduction in GHG emissions.



Duct Leakage 101: Why do ducts leak?

Construction & Installation
Duct work is folded sheet metal that relies on manual installation and sealing. Unfortunately, quality of workmanship is widely inconsistent and lacks proper testing.
Manual Sealing Materials
Common materials such as mastic and tape deteriorate over time, further reducing the airtightness of your ductwork.
Renovations & Additions
Drill holes, disconnected and crushed ductwork are all common deficiencies found above the drop ceiling, caused over time by ancillary projects or contractors.

"For decades, the problems associated with duct leakage in commercial buildings have typically been underestimated for one simple reason — fixing the problem has been a highly expensive and intrusive proposition.”
