Aeroseal startup seals leaky homes to reduce energy use, lower costs

Leaky homes and buildings are some of the greatest climate offenders, but a Dayton, Ohio-based start-up is making big gains in shoring up the problem. Aeroseal, which seals both air ducts and building envelopes, is now available across America and in 29 countries.

Leaky airducts and walls are the single largest reason for wasted energy in homes. Typical systems can lose between 25% and 40% of the heating or cooling energy put out. While newer homes are built more tightly, old homes are major culprits. Reducing that wasted energy not only lowers consumers’ bills, but also reduces emissions associated with energy production, which are a significant contributor to climate change. Overall,…
