4. Power-Save Duct Seal System

Duct sealing is a combination of Power-Save Radiant Barrier and Power-Save Duct Seal.
Leaky ducts can reduce heating and cooling system efficiency by as much as 20 percent. Sealing and insulating ducts increases efficiency, lowers your energy bills, and can often pay for itself in energy savings.
Plus, if you’re planning to install new heating and cooling equipment, a well-designed and sealed duct system may allow you to downsize to a smaller, less costly heating and cooling system that will provide better dehumidification.
1) tape all seams in duct work
2) wrap all duct work with radiant barrier
3) use same tape to attach radiant barrier to duct work and seal all seams
