Go with a tape with a broad functioning temperature variety, especially for HVAC or industrial use. Some tapes functionality in ranges from -20°F to 300°File or higher.
3. Thickness
Thicker tape typically usually means extra toughness and better functionality in sealing and warmth resistance. However, it may be more difficult to apply all over restricted corners.
four. UL Certification
For HVAC use, UL181A-P or UL181B-FX certification assures the tape fulfills fireplace and security standards.
five. Moisture & UV Resistance
Make sure the tape is ideal for outside use if wanted. UV and moisture resistance will reduce degradation with time.
How to Apply Foil Tape Accurately
