DUCT TIGHTNESS TEST
As required in IL by the 2018 IECC, all forced air systems with ducts passing through unconditioned spaces (attics, garage ceilings, cantilevered floors, etc.) must be tested for leakage. If the duct system has no exposure 'to outside', the system must still be sealed but leak testing is not required. Check with your code official for the final word.
The best time to test for duct leaks is as soon as the supply & return ducts are ‘roughed in’ – before they are covered by insulation & drywall. This way leaks can be accessed and sealed easily. If tested after finishes are installed, all wall grilles must be removed to better ensure a passing result.
Insight can also train your employees in cost effective duct sealing techniques (eg. use mastic – NOT foil tape) and can serve as the approved 3rd party to test for duct leakage. Consult with Insight for cost saving strategies to build tight duct systems.
