Industry-Leading Duct Sealants: Engineered to Perform. Certified to Protect.

Article content provided by Carlisle HVAC

Not all duct sealants are created equal. With energy codes tightening and system performance under scrutiny, choosing a trusted, UL-listed solution is more important than ever. Liquid Mastics from Carlisle HVAC go beyond the minimum UL 181 standards. Rigorously tested and certified, they deliver professional-grade performance across every jobsite, including metal duct, flex duct, duct board, or fabric.

The Carlisle Difference

Many commoditized sealants may carry the UL logo but don’t meet the complete listing requirements. Versa-Grip 181 is UL 181A-M & UL 181B-M Listed, plus exceeds ASTM and EPA standards for full compliance and peace of mind. Take a Look:

Built-in polyester reinforcement for added strength
UV inhibitors for outdoor exposure
UL181A-M and UL181B-M Listed
Passes ASTM C-731 & D-2202
LEED-compliant, EPA, FDA, and USDA-approved
Mold and mildew resistant
Meets CDPH Standard Method V1.2-2017
