3. Thickness
Thicker tape generally means more longevity and improved general performance in sealing and warmth resistance. Even so, it may be harder to use all around tight corners.
four. UL Certification
For HVAC use, UL181A-P or UL181B-FX certification guarantees the tape satisfies hearth and safety standards.
five. Moisture & UV Resistance
Make sure the tape is suited to outdoor use if wanted. UV and foil tape moisture resistance will avoid degradation with time.
How to use Foil Tape Effectively
