three. Thickness
Thicker tape commonly signifies far more sturdiness and much better overall performance in sealing and warmth resistance. On the other hand, it might be tougher to use all over restricted corners.
4. UL Certification
For HVAC use, UL181A-P or UL181B-Forex certification guarantees the tape satisfies hearth and safety standards.
five. Moisture & UV Resistance
Make sure the tape is ideal for out of doors use if essential. UV and moisture resistance will reduce degradation after some time.
How to Apply Foil Tape The right way
