one. Adhesive Toughness
Glimpse for top-tack adhesive that bonds right away and forever. Some tapes use acrylic adhesive for extensive-Long lasting maintain in Serious temperatures.
2. Temperature Selection
Opt for a tape with a large foil tape working temperature variety, especially for HVAC or industrial use. Some tapes function in ranges from -twenty°File to 300°F or higher.
three. Thickness
Thicker tape commonly suggests far more sturdiness and much better overall performance in sealing and heat resistance. Having said that, it might be more difficult to apply all over restricted corners.
4. UL Certification
For HVAC use, UL181A-P or UL181B-Forex certification assures the tape meets fireplace and security standards.
five. Moisture & UV Resistance
Make sure the tape is appropriate for outdoor use if wanted. UV and dampness resistance will prevent degradation eventually.
How to Apply Foil Tape Correctly
