Select a tape with a wide functioning temperature range, specifically for HVAC or industrial use. Some tapes purpose in ranges from -twenty°F to 300°File or bigger.
three. Thickness
Thicker tape commonly usually means extra longevity and improved overall performance in sealing and heat resistance. However, it may be harder to use all over restricted corners.
4. UL Certification
For HVAC use, UL181A-P or UL181B-Forex certification assures the tape meets fireplace and basic safety expectations.
5. Humidity & UV Resistance
Make sure the tape foil tape is ideal for outdoor use if desired. UV and dampness resistance will avoid degradation as time passes.
How to use Foil Tape Effectively
Making use of foil tape is easy, but some ideal methods ensure most functionality:
Clean the Floor: Eliminate any Dust, oil, or moisture right before making use of the tape.
Evaluate & Reduce: Pre-evaluate the length you must steer clear of squander.
