HVAC construction contractor Cool Zone Inc. knew cleaning and sealing the ductwork of a 27,000-square-foot facility in south Florida wouldn’t be simple.
The building’s dual-wall spiral duct was painted purple, leaking and exposed to the interior as part of the building’s design. Cool Zone faced a problem: no sealant could be applied to the outside of the ductwork, and no access holes could be cut to clean or apply sealant to the interior, as either would mar the building’s appearance. These factors meant the ductwork had to be sealed from the inside.
