What is MEZ-AEROSEAL?
MEZ-AEROSEAL is a unique technology for efficient and effective sealing of already installed air duct systems from inside out.
As an integral component in the construction of new ventilation systems, maximum air tightness requirements for installed systems can be guaranteed as well as achieved.
It doesn't matter if you have to deal with restructuring or retrofit, MEZ-AEROSEAL seals the air duct system fast, efficient and the required airtightness class can be achieved. The patented AEROSEAL process was developed in the 1990s at the University of Berkeley/California. This technology has been successfully applied in more than 125,000 air duct systems, in residential as well as commercial buildings, all over the world.
Since 2015 MEZ-AEROSEAL sets new standards for the tightness of air duct systems all over the world.
How Does MEZ-AEROSEAL Work
The sealant which is soluble in water is transformed into a gaseous state using heated compressed air. The aerosolized particles seal the whole leakage of the ventilation system. One leak after another up to a diameter of 1,5 cm are sealed and withstand a pressure of up to 2.000 Pa.
Why is MEZ-AEROSEAL the new airtightness class?
Due to limited access to already installed air duct systems and the fact that small and individual leakages are the problem, the sealing of those systems has been extremely difficult I as well as inefficient so far. As a result of the achievement of air tightness class C or D for an already installed air duct system was usually not possible.
With MEZ AEROSEAL you are able to guarantee airtightness class D. This sealant, transported by the airflow, seeks for leakages within the air duct system and attaches directly onto the edges of those. Using this process you are able to achieve results like you would only achieve with welded or very elaborately sealed air ducts.
Your building's energy consumption can be hugely reduced by sealing ductwork with Aeroseal:
- Aeroseal duct sealing has been proven to be 95% effective at sealing ventilation duct leaks.
- It reduces the amount of power needed to circulate air through ventilation systems. In your building, operating HVAC fans represents 20-60% of your total HVAC energy usage. Independent studies have shown that even a 15% reduction in leakage can reduce fan power requirements by 40% or more – and save you thousands of dollars.
- - It reduces energy waste caused when an improperly pressurized building draws unconditioned air in through cracks around doors/windows and through holes in the building shell.
- -Finally, duct leakage has been linked to excessive outside air intake through the HVAC system. This extra ventilation air significantly increases the operating cost of the HVAC system.
Holes in ducts mean higher operating costs, harder working HVAC components, and poor building performance. Sealing ducts will help these issues, and with solving BMS problems, operating to HVAC design specifications and continuous commissioning. Airtight ventilation ducts are essential for smart buildings - and smart building owners. Strategic and forward-thinking building owners and managers realize the advantages of providing living and working spaces that are comfortable, healthy and appealing. They know a building with great thermal comfort and indoor air quality will keep occupiers happy, productive, and extending their leases. When tenants experience high indoor environmental quality, tenant turnover is lower.
Aeroseal was invented in America in 1994, and it’s been used in US homes, and commercial, healthcare and hospitality buildings since 1997. In 2013 Aeroseal was approved by Home Innovations Labs (US) as a National Green Building Standard (NGBS) product. The National Green Building Standard is the only residential green building rating system approved by the American National Standards Institute (ANSI) as an American National Standard. Homes that attain NGBS certification have proven to meet high standards for energy efficiency, sustainability, and indoor air quality.
