# Don't Just Tape It, Seal It!

#### Did you know that improper sealing of ductwork results in 24–40% loss in HVAC Systems?

Leakage is serious — it affects air quality, can reduce system capacity and the life of an HVAC unit. To reach maximum efficiency, you need a seal that lasts. Hardcast® rolled mastic sealants are designed to seal metal or flexible duct work for the life of the system. These pressure-sensitive, Zero-VOC sealants bond to metal instantly with no mess or cure time−and you can perform pressure tests right away! 

## **Efficiency Begins With the Right Seal**
