Aeroseal

Based in Miamisburg, USA, and founded in 2010, Aeroseal has developed a proprietary duct and air sealing technology for residential and commercial buildings. What was the problem with our buildings, you’re asking? Well, heating and cooling systems, as well as walls and ceilings, often leak air 💨. Fixing these leakages tends to be very time-consuming and expensive, but is an important way of reducing our building energy use. That’s where Aeroseal comes in. Their technology connects to a building’s heating or air system to measure the total leakage, and directly distribute the sealing formula throughout the building’s air system. This means buildings are insulated within a day, and homeowners know precisely how much energy they are going to save. Why is Aeroseal able to do this better than the norm? Founder Mark Modera invented a non-toxic, aerosol- and water-based formula that allows to seal holes in air ducts and vents from the inside out, instead of the traditional outside-in. This makes the process less labour intensive (and more effective). 2150 participated in a funding round next to Breakthrough Energy Ventures and Energy Impact Partners.

Aeroseal’s mission is to significantly reduce the energy usage of buildings while saving money, delivering comfort and improving air quality. Building’s heating and cooling systems are inefficient. Often, buildings also leak air through their walls and ceiling, which causes massive energy losses. Fixing these leakages can be extremely difficult. Aeroseal’s proprietary technology makes this a whole lot easier. The realized energy savings not only decrease homeowners’ bills but also CO2 emissions from energy consumption.

Aeroseal has a proprietary duct and air sealing technology for residential and commercial buildings. Their process ensures precise sealing in a few hours. Aeroseal connects their technology to a building’s heating or air system to measure the total leakage of a building’s heating and cooling system and distribute the sealing formula throughout the building’s air system directly after. This way, buildings are insulated within a day, and homeowners know precisely how much energy they are going to save.

Aeroseal has developed a non-toxic, aerosol- and water-based formula that can be pumped throughout an air system and effectively seals the holes in air ducts and vents. The breakthrough achieved by this formula is that it allows to seal holes from the inside out, making the process less labour-intensive.

If Aeroseal’s technology is deployed at scale, it could mitigate more than half a gigatonne of CO2 emissions per year. This means they would achieve the sought-for gigacorn status. Given this opportunity and the company’s accelerating commercial traction, 2150 participated in a funding round alongside Breakthrough Energy Ventures and Energy Impact Partners in August 2021. 2150 believes they can add value to Aeroseal’s growth process by increasing their visibility and distribution across Europe.

The greenhouse gas (GHG) emissions from heating and cooling buildings have more than doubled since 1970 and currently represent 25% of global emissions (IPCC). We now know how to build GHG neutral or GHG positive buildings, and are building a lot of them, but that’s not enough to get us to the Paris Agreement. That’s because 85%-95% of the buildings we will have in the EU in 2050 have already been built today. And many of these buildings are leaking a lot more hot and cold air than we would like them to.

Fine, you might think, let’s knock all these buildings down and replace them with carbon-neutral buildings. Some other problems aside, like the emotional and historical value that buildings have or the gigantic financial cost of doing so, this wouldn’t solve the GHG problem either. Today, the construction industry is responsible for about 15% of global emissions, which partially come from fossil fuels burned during the construction process, but mostly from the materials used, like steel and concrete. And that is at the current building rate. From a material perspective, it is way less GHG efficient to knock down and rebuild from scratch than to retrofit. As such, the European Union is urging countries to retrofit more.

For Europe to reach climate neutrality by 2050 we need to renovate more than 90.000 homes – and that’s per week. For this, we need effective technologies and innovative business models. Often, homeowners are quite reluctant to renovate their homes, even if they could get some financial and GHG savings, just because it is such a hassle to do so. You have to take the time to find the right technology, the right vendor, get your house ready, and hope that nothing goes wrong in the process.

This is where Aeroseal comes in. Not only is their technology cheaper than alternative insulation technologies, but it is also installed quickly, easily, and they are friendly to their customers in the process. Sealing a typical building in the US can yield up to 30-40% energy savings, which leads us to believe that Aeroseal has the potential to become a Gigacorn (i.e. to mitigate at least 1% of global GHG emissions (500 Mt) per year). To achieve this, Aeroseal’s technology would have to be deployed at scale. And we believe they can reach this scale, especially with 2150’s help to accelerate their visibility and distribution in Europe.
