• Opposing temperature is attempting to be delivered to a conditioned space through the hostile unconditioned attic creating unintentional heat escape.
• Ductwork (particularly the return) negative pressure sucks attic air dust pollutants  through the seams and gaps.
• Ductwork temperature differences can create excess humidity and moisture in your attic

Attic Ductwork Installation

• Ductwork in an unconditioned space should be in direct contact with the ceiling / attic floor.
• Ductwork in attic insulation should include a vapor barrier.
• Attic ductwork should be secure.
• Ductwork should prevent any air escape at the seams.
• Ductwork should be covered with 1″ of closed cell spray foam if accessible to seal all seams, provide a thermal barrier, as well as a moisture barrier.
• Sealing attic ductwork saves energy, saves money month after month, improves efficiency, and comfort.
