The Sealants, Tape & Insulation category covers the materials that tighten up the airside and waterside of your HVAC system—from sealing duct joints and plenums to insulating line sets, piping and penetrations. Done correctly, these details improve comfort, efficiency, equipment life and code compliance while reducing callbacks tied to sweating lines, leaky ducts and drafts.
Here you’ll find duct mastics, aerosol and brush-on sealants, foil and FSK tapes, UL-rated duct tape, pipe and line-set insulation, foam sealants, weatherstripping, gasketing and insulation accessories. These products support work on supply and return duct systems, air handlers, rooftops, refrigeration and mini-split line sets, chilled-water and hot-water piping, chase penetrations and exterior wall terminations.
When selecting sealants, tape and insulation, confirm temperature rating, surface type, indoor/outdoor exposure, vapor barrier requirements, code listings (UL, ASTM, IECC) and compatibility with the duct or piping material. Using the wrong product can lead to peeling tape, failed vapor barriers, condensation, mold risk or energy loss. The right materials help lock in system performance for the life of the installation.
Pro tip: Treat line-set and duct sealing as part of your commissioning checklist. Verify all joints, seams and penetrations are sealed and insulated before closing ceilings or walls—it’s far easier than trying to fix comfort complaints after the space is occupied.
