Premium HVAC Aluminium Foil Tape — High-Performance Ductwork Sealing

If you're installing or repairing HVAC ductwork, the tape you use at the joints matters as much as the ductwork itself. A poor seal loses conditioned air, wastes energy, and can let moisture into insulation. Supraseal's Premium HVAC Aluminium Foil Tape is engineered for demanding, professional applications — a premium foil backing with high-tack acrylic adhesive designed to hold firm through heat, cold and condensation. Coming soon — register your interest here to be notified when it launches. What Is HVAC Foil Tape? HVAC aluminium foil tape is a metallised tape used to seal seams, joints and punctures in ductwork, and to finish insulation wraps on pipework. Unlike standard cloth "duct tape" (which isn't actually rated for ducts), foil tape is designed to withstand the temperature swings and airflow pressure inside a working HVAC system. Why foil tape instead of cloth duct tape? Cloth duct tape adhesive dries out and fails within months on HVAC systems Foil tape reflects heat and matches the thermal properties of metal ductwork Meets the standard expected for insulation and ductwork sealing on most installations Where to Use It Sealing joints and seams on sheet metal or flex ductwork Wrapping and finishing pipe insulation Patching small punctures or tears in ducting Sealing insulation board joints in HVAC plant rooms General vapour-barrier sealing on cold-water pipework How to Apply HVAC Foil Tape Clean the surface — dust, oil or condensation will stop the adhesive bonding properly Dry-fit the tape length before peeling the backing, so you're not fighting it once it's tacky Apply firm, even pressure along the full length — a seam roller gives the best bond Overlap joints by at least 25mm for a fully sealed edge Smooth out any air bubbles immediately; foil tape doesn't reposition well once set Supraseal Premium HVAC Aluminium Foil Tape — 50mm x 50m (Coming Soon) Our HVAC tape is being brought to market for tradespeople who need a reliable, professional-grade seal first time, every time.

FAQs Can I use HVAC foil tape outdoors? Once launched, Supraseal HVAC tape will be moisture resistant and suitable for external ductwork and pipe runs, though it should still be protected from prolonged standing water. Does foil tape work on flexible ductwork as well as metal? Yes — foil tape of this type bonds to both rigid sheet metal ducting and flexible ducting, provided the surface is clean and dry before application. How long does the roll last once opened? Store rolls flat in a dry place away from direct heat; unopened rolls typically have a long shelf life, but always check adhesive tack before a job if a roll has been open a long time.
