one. Adhesive Power
Seem for prime-tack adhesive that bonds promptly and forever. Some tapes use acrylic adhesive for very long-Long lasting maintain in Excessive temperatures.

2. Temperature Assortment
Pick a tape with a wide operating temperature range, specifically for HVAC or industrial use. Some tapes functionality in ranges from -twenty°F to 300°File or better.

3. Thickness
Thicker tape typically implies a lot more durability and better performance in sealing and warmth resistance. Having said that, it could be more challenging to apply about tight corners.

four. UL Certification
For HVAC use, UL181A-P or UL181B-FX certification guarantees the tape meets fireplace and basic safety expectations.

5. Moisture & UV Resistance
Make sure the tape is appropriate for outdoor use if desired. UV and humidity resistance will avoid degradation with time.

How to Apply Foil Tape The right way
