Aeroseal® Duct Sealing From the Inside

Aeroseal is the most effective, affordable and viable method of sealing duct leaks. Just like anywhere else, ducts in commercial buildings leak…and leaking ducts cost you money. Here’s how you can save:

  • Decreased energy consumption. With fan power representing 40-50% of HVAC energy usage, leakage costs can be significant due to increases in fan speed. 
  • Decreased Thermal Loss. When supply air escapes, variations in temperature between rooms and floors occur affecting comfort levels in the space. 
  • Longer Equipment Life. Your system will run longer than specified to compensate for pressure loss and temperature accuracy; this could lead to increased maintenance costs and premature component replacement. 
  • Prevents Code, Airflow &Safety Issues. Leakage could lead to ventilation and safety code issues related to exhaust, along with excessive power use.

Aeroseal®Duct Sealing




 Efficiency. Reliability. Comfort.



• Attract and retain visitors and tenants
• Reduce costs for heating and cooling
• Ensure comfort
• Provide cleaner, fresher atmosphere
• Comply with safety regulations and codes
• Contain energy costs
• Have better resale value

“We were all highly skeptical that duct leaks could be
responsible for the issues we were having with the ERV system
and that this new duct sealing technology could solve the problem.
We were wrong on both accounts. Aeroseal was not only the
fastest, easiest and least expensive option, it turned out to be the
most effective. Aeroseal worked an absolute miracle on this system.
Hard to believe.” —Daniel Carley, Project Manager Dolyn Developments Inc.

Is Your Small Building a Foundation

 for Visitor and Tenant Retention?

A high-quality environment is critical to visitors, tenant
satisfaction and worker productivity. Comfortable
spaces can increase membership, visitation and tenant

Essential for Light Commercial Facilities Is That They:
• provide evenly balanced air temperatures throughout
all spaces creating better air flow
• provide comfortable spaces for more visitor and
tenant satisfaction and worker productivity
• save significant amounts of spending on wasted air
leakage and equipment overload
• reduce toxins, particles, and microbials and provide
fresher air

Proven Positive Outcomes in Commercial Spaces
A typical light commercial building loses 25-40%
of heating and cooling energy through the ductwork.
Aeroseal reduces up to 90% of that duct
leakage. And, our commercial duct sealing system
will reduce heating and cooling costs by up to 20%.

Our Duct Sealing Solution Covers:
• offices and retail spaces
• gathering areas and conference rooms
• the building base and control centers
• waiting and work spaces
• storage spaces

Case Study
St. Alban’s Church in Ottawa, Canada
A 145 year-old stone building, St. Alban’s is the oldest
church in the city. Recent renovations to the interior
included an energy efficient ERV system and new ductwork
to increase the indoor comfort and improve the
ventilation in this historic landmark. Once installed, the
system was tested with disappointing results. The ERV
wasn’t drawing in or blowing out a sufficient amount of
air to do its job…no matter how hard they ran it.

Goal: Fix heating system / improve ventilation
Before Aeroseal: Losing 665 CFM of treated air
After Aeroseal: Losing 49 CFM, a 93% reduction
Results: ERV system had enough air from ductwork to
work properly; ventilation fixed
