Near-Nil Leakage with Q Lok

Q Lok® Obtains Near-Nil Leakage Rating

Do you like the sound of near-nil leakage​? For outdoor duct systems, air leakage can be a major cause of degraded system performance and energy loss. Not to mention a path for water to seep into the ventilation, causing mold and mildew. The Q Duct system is the only product on the market that utilizes a patented interlocking flange-less duct connection tested to meet and exceed SMACNA Class 1 Leakage rates.

Q Lok®, with its quadruple interlocking system with redundant seals, ensures industry-low leakage resulting in maximum energy efficiency!
