What is the Difference Between AeroSeal and AeroBarrier?

Introduction

Air sealing technology is crucial in ensuring energy efficiency and improving indoor air quality in buildings. Two prominent technologies in this domain are AeroSeal and AeroBarrier. While both are designed to seal leaks and improve air tightness, they serve different purposes. AeroSeal is primarily used for sealing ductwork, whereas AeroBarrier is used for sealing the building envelope. Understanding the differences between these two technologies can help in making informed decisions for construction and renovation projects.

Origins of AeroSeal and AeroBarrier

AeroSeal emerged as a groundbreaking technology aimed at sealing air duct systems from the inside out. It was developed to ensure that air ducts are sealed to an air-tight level, significantly improving HVAC efficiency. On the other hand, AeroBarrier is a spinoff of AeroSeal, developed with a focus on sealing the building envelope. As detailed by Fine Homebuilding, both systems use compressed air to aerosolize a water-based sealant, but AeroBarrier also employs the pressure from a blower door to force the sealant into gaps and cracks.

How AeroSeal Works

AeroSeal is a revolutionary technology that seals ductwork to improve air quality and energy efficiency. Here’s how it works:

  • A pre-seal test is conducted to measure the total leakage in the duct system.
  • The vents are temporarily blocked, forcing air to escape through leaks.
  • Compressed air is used to aerosolize a water-based sealant that is injected into the duct system.
  • As the air moves through the ducts, the sealant particles are deposited at the leak sites, gradually sealing them.
  • A post-seal test is conducted to verify the sealing results.

The technology behind AeroSeal allows for precise sealing, ensuring that the ductwork is air-tight and that the HVAC systems operate at optimal efficiency.

How AeroBarrier Works

AeroBarrier seals building envelopes in a similar manner to how AeroSeal addresses leaks in ductwork. The process involves:

  • Setting up a blower door to pressurize the building.
  • Using compressed air to aerosolize a water-based sealant, dispersing it throughout the home.
  • The blower door pressure forces the sealant into gaps and cracks in the building envelope.
  • The sealant accumulates in the leaks, effectively sealing them.

The technology behind AeroBarrier is highly effective and can seal leaks up to 1/2" in size. It is the only method that guarantees any level of air tightness the first time, every time, as stated on the AeroBarrier Homepage. This makes it an invaluable tool for achieving energy-efficient building standards.

In summary, while both AeroSeal and AeroBarrier use similar materials, they are applied differently and serve different purposes. AeroSeal is essential for sealing ductwork, while AeroBarrier is crucial for sealing the building envelope. Both technologies play a vital role in ensuring energy efficiency and improving indoor air quality.

Comparing AeroSeal and AeroBarrier

AeroSeal and AeroBarrier, while developed from the same origin, serve different purposes in air sealing.

Similarities:

  • Both use a water-based sealant that is aerosolized.
  • Both are aimed at improving the energy efficiency and air quality of buildings.
  • Both technologies were developed to seal leaks in a building’s structure.

Key Differences:

Application:

  • AeroSeal is specifically designed for sealing leaks in air duct systems.
  • AeroBarrier is designed for sealing the building envelope, including walls and ceilings.

Results:

  • AeroSeal ensures that HVAC systems operate efficiently by sealing the ductwork.
  • AeroBarrier ensures overall building airtightness, which is crucial for energy efficiency and indoor air quality.

Benefits of Using AeroBarrier

Utilizing AeroBarrier for air sealing has several advantages:

  • Time Efficiency: The AeroBarrier process is much faster compared to traditional manual sealing methods.
  • Precision and Reliability: It can effectively seal even the tiniest cracks and gaps, ensuring a high level of airtightness. According to AeroBarrier's Homepage, it's the only method that guarantees any level of air tightness the first time, every time.
  • Cost-Effectiveness: AeroBarrier reduces the need for multiple trades and contractors, making it a more cost-effective solution in the long run.

FAQs

What is AeroBarrier sealant?

AeroBarrier sealant is a water-based, non-toxic sealant that is used in the AeroBarrier air sealing process. It is aerosolized and then applied to the interior of a building. Through a pressurized process, the sealant is forced into cracks, holes, and gaps in the building envelope, effectively sealing them. This technology is revolutionary in achieving desired levels of airtightness in a building. We have created a Comprehensive Guide to AeroBarrier that explores this further.

What are the benefits of AeroBarrier?

Using AeroBarrier offers several advantages:

  • Time Efficiency: It significantly reduces the time required for air sealing.
  • Precision: Capable of sealing even tiny cracks and gaps that are otherwise hard or impossible to reach.
  • Cost-Effectiveness: Reduces the need for multiple trades and contractors.
  • Improved Indoor Air Quality: Prevents the ingress of pollutants.

What are the benefits of AeroSeal?

AeroSeal is primarily used for sealing ductwork in HVAC systems, and it offers the following benefits:

  • Energy Efficiency: By sealing air leaks in ductwork, it ensures that HVAC systems operate at optimal efficiency.
  • Improved Air Quality: Prevents dust and pollutants from entering through leaks.
  • Cost Savings: Reduces energy bills by ensuring minimal loss of heated or cooled air.

How long does AeroBarrier last?

AeroBarrier is designed to be durable and long-lasting. The exact lifespan can vary based on environmental factors, but it is generally expected to last for many years. The sealant used in AeroBarrier is robust and can withstand the typical stresses and conditions of a building's interior environment. For additional information, see the Durability Testing document on our Resources Page.

Conclusion

In summary, AeroSeal and AeroBarrier are both groundbreaking technologies that address air sealing in different domains. While AeroSeal is indispensable for sealing ductwork and optimizing HVAC systems, AeroBarrier is essential for sealing the building envelope and ensuring overall building airtightness. As the construction industry evolves, these technologies are poised to play a pivotal role in the future of air sealing, driving energy efficiency and sustainability in buildings.
