The Defender Fire Suppression System
An Introduction to Aeroseal
Aeroseal is a breakthrough aerosol-based sealing technology developed in 1993 by Dr. Mark Modera in his garage. For the first time ever it was possible to seal leaks in ducts from the inside out.
The problem is most ducts in commercial buildings leak air and this was chalked up to a common problem one that was just accepted. Case studies have shown sealing ducts reduces energy waste by eliminating the cracks & holes.
WHAT IS AEROSEAL?
AEROSEAL is a patented technology for efficiently and effectively sealing of existing air duct systems from inside out in the quickest possible way and with little disruption.
Ductwork leakage rates are outlined in BESA DW144 and systems should be manufactured and installed to comply with this specification.
Now as an integral component in the installation of new ventilation systems, maximum air tightness requirements for duct work can be guaranteed as well as achieved
The revolutionary and patented AEROSEAL process was developed in the 1990s at the University of Berkeley/California. This technology has now been successfully applied in more than 125,000 air duct systems, in residential and commercial buildings, all over the world.
Since its European launch in 2015 AEROSEAL has set new standards for the tightness of air duct systems.

This Has A 2 Fold Effect
- The motors in HVAC systems use on average 60% of a buildings electricity. According to VIP40 an international commissioned report on ventilation systems the ductwork across Europe leaks anything from 15% to 40%. By reducing leaks from 15% down to 2% which AEROSEAL can do, drops fan requirements by a multiple of 3 resulting in a 39 to 40% energy saving in your HVAC system. Saving thousands of Euros every month and contributing to a reduction in CO2 emissions.
- It also helps in reducing contamination in the ducts which is drawn in to the system through the holes in the ductwork. As a direct result this cuts down on cleaning costs and helps to maintain Indoor Air Quality (IAQ).
- As direct result by sealing leaky ductwork, there is more airflow to the targeted areas. This can allow increased occupancy.
- Reduced noise contamination
In Conclusion AEROSEAL’s solution has made duct sealing cost effective & simple to accomplish, making it a top energy saving strategy for building owners and Facility Managers looking to eliminate energy consumption and improve IAQ problems.
A WIN-WIN SOLUTION FOR EVERYONE INVOLVED
AEROSEAL provides facility managers and energy efficiency consultants with a simple and effective method of optimizing leaking air ducts in existing buildings and reducing energy costs.
- Planners can guarantee that the complete ventilation system meets the requirements of the standards for tightness when AEROSEAL issues a tender.
- Air duct manufacturers can prove that they meet the tightness requirements of DIN EN 1507 or DIN EN 12237 through their operational quality assurance and through the use of high-quality manufacturing products in production, manufacturers no longer have to deal with defects caused by the installation process.
- Plant constructors can easily meet and prove the required tightness class during the installation of a plant. Costly reworking or the processing of defects is no longer necessary.
- Operators and users benefit from optimal, energy-saving and efficient operation of the system.
WHY IS AEROSEAL THE NEW AIRTIGHTNESS CLASS?
In the past limited access to already installed air duct systems and the fact that small and individual leakages are difficult to address efficiently, the sealing of those systems has been extremely difficult. As a result, achieving leakage rates outlined in BESA DW144 and an air tightness class C or D for an already installed air duct system was usually not possible.
With AEROSEAL we are able to guarantee airtightness class D.
How Does Aeroseal Work?
Aeroseal works by introducing a water-soluble sealant aerosol into the ductwork system, allowing for effective sealing of leaks from the inside.
step
1
Pre Seal Test
Once the equipment is set up and attached to the section of ductwork to be sealed a pre seal test is run to check the starting leakage rate
step
2
Coverage and Accessibility
Aeroseal works by introducing a water-soluble sealant aerosol into the ductwork system, allowing for effective sealing of leaks from the inside.
step
3
Long-Lasting Durability
Once cured, Aeroseal’s sealant withstands pressures up to 2000 Pa, with an expected lifetime of over 30 years, assuming the ductwork remains intact and is not cleaned with oxidizing agents.
step
4
Temperature Resistance and Odorless Finish
The cured sealant is odorless, capable of withstanding temperatures from -29°C to +249°C.
step
5
High-Efficiency Leak Reduction
Leakage points up to 15mm in diameter can be sealed in one application, achieving over 90% reduction in system leakage. This allows systems to meet design specifications and may enable upgrades to higher classifications.
step
6
Once completed
A post sealing test is run to document the savings and this is finished with a sealing report and graph of the process showing savings
BENEFITS OF INCREASED AIR TIGHTNESS
Enhanced air tightness in ductwork systems leads to significant energy savings by reducing leakage, directly lowering HVAC operating costs and energy consumption. This improved efficiency not only enhances indoor air quality (IAQ) and building comfort—key to occupant productivity and well-being—but also supports environmental commitments by minimizing carbon footprint.
The Aeroseal process enables HVAC systems to operate with reduced fan speeds, even allowing for smaller fan sizes in some cases, while still delivering the necessary air volumes.

- Ductwork systems that have a better air tightness, lose less energy than leakier ones. HVAC running costs make up a very substantial part of a building’s operational cost and some of this cost may be recovered by reducing ductwork leakage.
- Energy saving calculations can be carried out after application, but it has been possible to reduce fan speeds and in some cases, reduce fan size after AEROSEAL, whilst still achieving the required air volumes.
- Poor performing HVAC systems can lead to poor indoor air quality (IAQ) and a reduced level of comfort in buildings. People can spend as much of 90% of their time in indoor space, and increased comfort and IAQ have proven benefits to productivity and reduced absenteeism.
- Comfort issues can be linked to poor temperature control from inefficient HVAC, these systems can have their efficiencies boosted by improved airtightness.
- AEROSEAL helps companies meeting the environmental commitments by reducing power consumption and therefore carbon footprint.
- 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 euros.
WHY DO DUCTS LEAK ?
Leakage may occur for many reasons, manufacturing tolerances, poor or faulty installation, damage in transit, poor on site adjustments as well as poor system design. It can often be very difficult to pinpoint areas of leakage, usually there are many points of small leakage which contribute to a much larger leakage total.
Ductwork flanged connections, slip joints, seams and fixings can all leak, making it almost impossible to find and seal all leakage points on a large installed system. Other building services such as walls, ceilings and other characteristics can restrict access to the ductwork system making manual sealing difficult.
The cured sealant is completely odourless and will withstand temperatures from -29C to +249C.
