Tape Model 363
The 3M 363 is a silver aluminium foil tape laminated to glass cloth. It is designed for HVAC control applications where a durable, reflective sealing material is required. The construction combines metal and fabric for strength in demanding environments.
Thermals Noise Power
The glass cloth backing resists high temperatures encountered in heating and ventilation systems. The aluminium foil surface reflects radiant heat to help maintain duct efficiency. No moving parts or electrical draw means silent operation with zero power consumption.
Build Fit
The tape adheres to sheet metal, flexible duct and insulation facing to seal joints and seams. Its conformable structure frees installers from rigid flashing or mastic for irregular connections. The roll format allows custom lengths without pre-cut waste.

Questions about this item
How do I apply the 3M 363 tape and what step is often missed?
Clean the surface thoroughly, then press the tape firmly with a roller to activate the adhesive; skipping the roller step leaves weak bonds.
Will the 3M 363 tape need replacement and how can I tell?
Replace it when the silver foil tears, the glass cloth frays, or the adhesive no longer holds against heat and vibration.
What limit appears first when the 3M 363 tape is used continuously in high heat?
The adhesive softens before the foil or cloth fails, causing the tape to lift or shift under sustained temperature.
