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 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 air tightness 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 sytems all over Europe and overseas.


How does MEZ-AEROSEAL
work?

The sealant which is souble 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 air tightness class?

Due to limited access of 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 a already installed air duct system was usually not possible.

With MEZ.AEROSEAL you are able to guarantee air tightness class D. This sealant, transported by the air flow, 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.

Even a significant undercut of the requirements of air tightness class D according to EN 1507, EN 12237, EN 12599, Eurovent or DW144 TM1 is possible.
