Aeroseal uses its patented interior sealing technology to seal air leaks in ducts and building envelopes, cutting energy waste and improving indoor air quality. The process involves applying the seal from inside the ducts to stop leaks, which can be used in homes, hospitals, schools, and government facilities. The technology is delivered through a network of providers to both residential and commercial customers worldwide. Unlike general HVAC services, Aeroseal focuses specifically on sealing, with a patented method that targets leaks from within, enabling effective energy savings across a wide range of buildings. The company aims to reduce global carbon emissions by lowering buildings’ energy use, contributing to cleaner, more efficient infrastructure across more than 30 countries.

Grosvenor has invested in Aeroseal, a climate technology company specialising in air sealing solutions, to improve building performance across its UK property portfolio. The investment focuses on addressing operational challenges in existing buildings, particularly heritage and complex assets where retrofitting can be disruptive and costly. Aeroseal's technology enables faster improvements in airtightness and energy efficiency with minimal impact on occupiers. A recent London trial demonstrated a 78.5% improvement in airtightness within a live operational environment. The investment aligns with Grosvenor's retrofit-first strategy, which prioritises extending building life over demolition to reduce embodied carbon. Grosvenor is working with Aeroseal to evaluate and deploy the technology across selected buildings, with potential for wider application. Grosvenor's Venture Investment team has invested £10 million to date in scale-up businesses and venture capital funds supporting its commercial and sustainability goals.
Miamisburg-based Aeroseal has laid off 40 employees globally, including approximately 20 in the Dayton area, representing about 10% of its workforce. The company develops proprietary ventilation shaft-sealing technology using water-based materials to seal holes in air ducts. Chief Executive Amit Gupta said whilst the company continues seeing strong market adoption and expects growth, "the pace of adoption has been slower than we anticipated". The redundancies are part of efforts to align the organisation with current market conditions. Aeroseal had previously projected significant expansion, with Gupta stating in September 2024 that the company had grown from 240 to 300 employees and planned to add another 50 jobs within six to 12 months. The technology is currently used by HVAC contractors across 50 states and 27 countries.
