Aeroseal
Aeroseal offers automated aerosol‑based sealing systems for HVAC ducts (Aeroseal Duct) and building envelopes (AeroBarrier). By pressurizing ducts or conditioned spaces and spraying a non‑toxic, low‑tack sealant that bonds only at leak points, the technology eliminates air leaks without demolition, provides real‑time leak monitoring, and delivers certified performance reports that help builders, contractors, and facility managers meet airtightness codes and achieve energy savings.

Problem
Air leakage in HVAC ductwork and building envelopes causes significant energy waste, higher utility costs, uneven indoor temperatures, and poor indoor air quality in residential and commercial buildings.
Solution
Aeroseal provides automated, aerosol‑based sealing technologies for ducts (Aeroseal Duct) and building envelopes (AeroBarrier). The system pressurizes the interior of ducts or conditioned spaces, sprays a non‑toxic, low‑tack sealant that travels to leaks and bonds there, sealing gaps from the inside. Real‑time monitoring and proprietary software verify leak reduction and generate certification reports, enabling builders, retrofit contractors, and facility managers to meet code‑required airtightness levels and achieve measurable energy savings.
Target Audience
Primary customers are residential builders, HVAC contractors, insulation and duct‑cleaning firms, and commercial facility owners or managers seeking to improve energy performance and indoor comfort.
Features
- Patented aerosol sealant applied from inside ducts or pressurized interior spaces, eliminating the need for invasive demolition.
- Automated equipment with wireless control and continuous blower‑door or duct‑blaster testing to monitor leak reduction in real time.
- Non‑toxic, water‑based sealant that only deposits where leaks exist, preserving duct integrity and indoor air quality.
- Certified results with post‑seal reports that quantify ACH or duct leakage reduction, supporting ENERGY STAR, Passive House, and other code compliance.
- Scalable for new construction, retrofits, and large commercial projects, with dealer network of over 1,500 certified installers worldwide.
