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

2. Temperature Variety
Select a tape with a wide foil tape operating temperature vary, specifically for HVAC or industrial use. Some tapes purpose in ranges from -twenty°F to three hundred°File or increased.

3. Thickness
Thicker tape normally usually means additional longevity and better functionality in sealing and warmth resistance. However, it could be more durable to apply close to restricted corners.

4. UL Certification
For HVAC use, UL181A-P or UL181B-Forex certification assures the tape meets fireplace and basic safety specifications.

5. Humidity & UV Resistance
Make sure the tape is well suited for outdoor use if needed. UV and dampness resistance will protect against degradation eventually.

How to use Foil Tape Effectively
