The Procedure

gesaAEROSEAL – ingeniously simple!

Thanks to its easy application, gesaAEROSEAL does not need lengthy explanations. Just learn hot the procedure works within a single minute!


What is gesaAEROSEAL?

gesaAEROSEAL is a patented breakthrough technology that tackles duct leaks from the inside out.

gesaAEROSEAL can be applied to existing or recently constructed duct systems.

gesaAEROSEAL duct sealing is used in commercial buildings around the world to increase energy efficiency and to set new standard regarding comfort and indoor air quality.

How does gesaAEROSEAL work?

The gesaAEROSEAL process puts escaping air under pressure and causes polymer particles to stick first to the edges of a leak, then to each other until the leak is completely sealed. Over time, leaks to a diameter of 1,5 cm can be sealed. These seals resist withstand pressure up to 2.000Pa.


What needs to be considered when using gesaAEROSEAL?

The entire process just takes a few steps. In a first step, all air-inlets and -outlets will be closed with metal panels, foam mats, sealing balloons, or MEZ-DUCT-WRAP – depending on the requirements. Generally, we avoid blowing sealant materiel through VAV boxes or fire/smoke dampers, however laboratory and field testing have shown that under the right circumstances this can be done without adverse consequences. However, we recommend disconnecting ventilators or recuperators and to remove or mask VAV boxes or fire/smoke dampers. Under no circumstances can sealant material be blown through VAV boxes with reheat coils.
