Aeroseal Envelope - AeroBarrier is a technology designed to improve the energy efficiency of buildings by sealing air leaks in the building envelope. Here's a breakdown of how it works and its benefits: What is AeroBarrier Sealing? AeroBarrier Sealing is a process that involves the use of a specialized aerosol-based sealant to find and seal leaks in ductwork and other parts of a building's envelope. This technology, known as Aeroseal Envelope - AeroBarrier, is particularly useful for improving the energy efficiency and comfort of residential and commercial buildings. How It Works Preparation: The area being treated is first prepared by blocking off any major openings to ensure that the sealant can be directed effectively where it's needed. Pressurization: The space is then pressurized using a blower, which forces air through the building's ducts or envelope. This pressurization helps to push the sealant particles toward any gaps or cracks. Application: An aerosol sealant is introduced into the air stream. The sealant is made up of tiny particles that are carried by the air and are attracted to and adhere to the edges of leaks and cracks. Sealing: As the sealant particles come into contact with leaks, they bond to the edges and build up over time to close off the gaps. Completion: Once the process is complete, the system is depressurized, and any residual sealant is cleaned up. Benefits of AeroBarrier Sealing Improved Energy Efficiency: By sealing leaks, the system reduces the amount of conditioned air that escapes, leading to lower energy bills and improved comfort. Enhanced Indoor Air Quality: Reducing leaks can help prevent dust, allergens, and other pollutants from entering the building, leading to better indoor air quality. Increased Comfort: Sealing gaps can help maintain a consistent temperature throughout the building, reducing drafts and cold spots. Cost-Effective: AeroBarrier Sealing can be less disruptive and more cost-effective than traditional methods of sealing leaks, which may require extensive labor and construction. Quick and Efficient: The process is relatively quick, often taking just a few hours to complete, and doesn't require extensive modification to existing structures. Applications AeroBarrier Sealing is typically used in: Residential Buildings: To improve energy efficiency and comfort. Commercial Buildings: To enhance HVAC system performance and energy savings. Ductwork: To address leaks in heating, ventilation, and air conditioning systems. Overall, AeroBarrier Sealing is a modern and effective solution for addressing air leaks and improving the overall performance of a building's envelope.
