Duct and Envelope Sealing

Automated air sealing for ventilation ducts, windows, and building envelopes

Duct and Envelope Sealing

Description

The Aeroseal Duct Sealing and AeroBarrier systems enable building owners to address energy waste — Aersoeal Duct Sealing turns a leaky HVAC distribution system into an efficient one, sealing holes up to 5/8 inch, while AeroBarrier turns a leaky building envelope into an airtight one. Both solutions leverage automated processes and real-time monitoring to ensure sealing results. They may be used to extend the life of existing heating and cooling systems, or to improve the ROI on new heating and cooling systems by ensuring that air is efficiently and properly distributed throughout a building.

Use Cases

  • Upgrade building envelope

  • Air seal building/unit

  • Make HVAC vents more efficient

  • Seal windows

  • Regulate indoor building temperature

Key Differentiators

  • Automated sealing - Aeroseal's Duct Sealing delivers automated, computer-controlled sealing from inside ductwork. AeroBarrier delivers automated envelope sealing. Both allow for faster installation than manual sealing

  • Non-toxic - Both solutions use patented, non-toxic sealants

  • Verified performance - Both solutions are monitored in real-time to ensure coverage and effectiveness

  • Precise - Aeroseal's Duct Sealing process pressurizes duct systems, driving sealant particles directly to leaks to seal them from the inside without coating the entire duct, with no demolition and minimal disruption. AeroBarrier is renowned for its ability to detect and seal even the smallest air leaks.

Cost Savings

These sealing solutions can save home and property owners and residents up to 30% of utility costs while extending the life and efficacy of HVAC equipment.

Decarbonization Impacts

Operational Emissions

While energy savings and CO2 reductions will vary significantly by building type (high rise, low rise), fuel type (steam, electric), and solution (ventilation rehabilitation, envelope sealing, or both), any reductions in the amount of energy wasted through air leaks will have a direct implact on carbon emissions as well. In fact, using an example of a New York City building, a recent study in the ASHRAE Journal showed that with pre-seal leakage of 16%, the Aeroseal energy model proved out savings across the categories of:

  • Reduced fan power

  • Reduced cooling and heating loads

  • Lower reheat requirements in VAV (variable air volume) systems.

  • Reduced peak electrical demand with results suggesting roughly 1% incremental energy savings for each percentage point of leakage sealed — representing substantial energy-saving and carbon-reducing potential for commercial and multifamily buildings; especially where initial leakage is high.

Embodied Carbon

AeroBarrier helps reduce a building’s embodied carbon by improving the overall effectiveness of the insulation system. Because the building envelope is much tighter, builders can often reduce or eliminate high-carbon materials like spray foam, use less traditional insulation, and even specify lower-performance windows — all while maintaining the same energy performance targets. Since AeroBarrier’s sealant itself has very low embodied carbon, it adds virtually no additional eCO₂ impact while enabling meaningful reductions in other, more carbon-intensive materials.

Project + Building Compatibility

Project Type

Both existing building retrofits and new construction

Essential Building Characteristics

Aeroseal's technologies work in a broad range of applications, with any insulation type, in any climate zone. Aeroseal Duct requires ductwork with leakage to seal, while AeroBarrier requires an enclosed space/building envelope where positive pressure and blower door testing can be used.

Ideal Building Characteristics

Any home or duct system with leakage that needs energy savings or envelope performance (all will benefit from our tech).

Minimum Project Size

Aeroseal’s direct sales team primarily targets projects above $100k, though smaller projects may still be considered through local channel partners. For high-rise multifamily ventilation retrofits, projects generally cost around $2k per unit, making a 100-unit building approximately a $200k project depending on scope and building systems.

Ideal Project Size

$100k-$500k high-rise multifamily ventilation retrofits or mid-rise new construction projects, generally involving 20+ stories and 200+ units

NY Contractor Availability

Installation contractors are available nationwide; Aeroseal has a network of certified contractors that are authorized to perform work on their behalf.

Other Screening Criteria

Aeroseal technology can be used in any project where energy savings, improved ventilation, and improved comfort are goals. This technology supports meeting code compliance, PHIUS, LEED, Energy Star, LIHTC, LL97 and other building performance requirements

Example Installations

Installed By

Multiple multi-family buildings in the Northeast including 150 West End Ave in NYC, Jaycee Place in MA, Northgate in NJ, and multiple AvalonBay communities. Aeroseal also works with clients such as Pfizer Pharmaceuticals, the American Dental Association, Steven Winters Associates, Ameresco, Johnson Controls, Beazer Homes, D.R. Horton, PulteGroup, and Disney, and has sealed buildings such as the Met Life Building, The Wynn Hotel, and several structures at Harvard and The Ohio State Universities.

Case Studies

Resident Experience

During Installation

Aeroseal Duct creates no mess and is typically completed in a couple of hours for homeowners. For commercial and high rise duct sealing, there is minimal disruption to residents with no demolition required. AeroBarrier is typically implemented in unoccupied areas, but if done in occupied spaces, would require several hours to days depending on the scope of work, to prep and cover finished surfaces such as counters, flooring, and windows. No demolition is required, and no residue or mess is left behind upon completion.

Post Installation

  • Improved comfort & indoor air quality

  • Even temperatures room to room

  • Reduced odor transfer between units

  • Less noise traveling through leaky pathways

  • Cleaner, controlled airflow

  • HVAC systems that perform as designed

Upfront Costs

Upfront costs are heavily dependent on the scope of work, the building size and type, the fuel type, the goals of the project, and other factors.

Payback Period

The average payback time is 3-10 years for Aeroseal duct sealing for multifamily housing.

Operations, Management, and Maintenance

Ease of Operations

Aeoseal's duct technology and AeroBarrier envelope sealing technology simplify envelope sealing and reduces uncertainty and variability. For one equipment platform, Aeroseal Duct leads to 66% faster prep and teardown. Aeroseal handles the process end to end with verified air tightness results.

Data + Performance

Aeroseal software generates a certificate of completion with before-and-after leakage test results, a graph of progress during the process, and heating and cooling capacity improvement.

Moisture Management

AeroBarrier virtually eliminates condensation and damp building materials in the exterior walls of a building.

Future Proofing

Aeroseal materials will be compliant with stricter building codes in extreme weather circumstances, positioning buildings for a resilient net-zero future.
