Brick NJ Attic with Encapsulated Ducts Eliminates Leaks and Boosts Comfort

Challenge

This attic in Brick, NJ, had radiant heat from the roof warming the homeowner’s ductwork during the summer. The ducts were leaking, causing the air conditioner to run constantly as the hot attic air heated the cooled air moving through the system. The thermal image clearly shows the duct leaks and temperature fluctuations throughout the ductwork.

Solution

We air-sealed the entire attic and installed 2-inch rigid foam boards with a radiant barrier around the metal ductwork. After securing all four sides, we sealed any remaining gaps with air sealant to create an airtight encapsulation. This eliminated duct leaks and stopped radiant heat from warming the cool air inside. With the ducts insulated, we sealed the floor decking and blew in TruSoft Cellulose insulation to an optimal R-60 level. The result is a properly insulated attic with sealed, encapsulated ducts—improving comfort and saving energy.

Thermal imaging reveals duct leaks and the radiant heat from the roof warming the ducts. This extra heat forces the AC to work harder, wasting energy, increasing bills, and reducing home comfort.

Comparing the thermal image with the photo of the leaky ducts shows that the connections aren't properly sealed, allowing air to escape into the attic. Essentially, the homeowner is paying to cool the attic as valuable cool air is wasted.

The ducts are now fully encapsulated and air-sealed. With no more leaks, properly insulated ducts ensure cool air flows efficiently, allowing the AC to cycle correctly, save energy, and prevent higher energy bills.
