Building Energy Codes Expand Certified Duct Sealing Requirements
Building energy codes across an increasing number of United States states and several other major markets now explicitly require UL 181-certified foil tape for HVAC duct sealing, replacing general-purpose cloth tape that inspectors previously accepted informally. Code enforcement intensity varies by jurisdiction, but the policy direction is consistent across nearly every major market MMA tracked, with certified tape increasingly specified explicitly in construction documents. Manufacturers with established UL 181 certification report order volume from HVAC distributors growing faster than general consumer channel sales, reflecting the segment's shift from optional upgrade toward mandatory requirement.
