Select a foil tape tape with a large working temperature assortment, especially for HVAC or industrial use. Some tapes perform in ranges from -20°F to 300°F or bigger.

three. Thickness
Thicker tape normally suggests more longevity and better efficiency in sealing and heat resistance. Nonetheless, it could be more durable to use about restricted corners.

4. UL Certification
For HVAC use, UL181A-P or UL181B-Forex certification ensures the tape fulfills fireplace and safety expectations.

5. Dampness & UV foil tape Resistance
Make sure the tape is suitable for outdoor use if wanted. UV and moisture resistance will avoid degradation over time.

How to Apply Foil Tape Properly
