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鈥檛 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
