Unlike traditional duct sealing that can only fix what the eyes can see, Nerva Duct Sealing works from the inside of the duct to seal leaks. This inside-out approach not only eliminates the demolition typically needed to access the ductwork, but also helps ensure the entire duct system can be quickly and easily sealed properly on the first attempt.
The sealing equipment is connected to the ductwork via a long, flexible tube and sealant is blown into the duct interior, where it automatically locates and seals the leaks. The microscopic particles of sealant do not coat the duct interior, but rather stay suspended in the air until they come in contact with a leak.
Driven under pressure where the only escape route is via leaks in the duct system, the sealant particles are propelled toward the leak where they cling to the edges of the hole and then to other surrounding sealant particles forming a bond that quickly covers the entire leak.
Ensure all areas are sealed to effectively pressurize the space.
Technology seals leaks and in real-time will display the results.
