Choose a tape with a large functioning temperature assortment, especially for HVAC or industrial use. Some tapes function in ranges from -twenty°File to three hundred°F or better.
three. Thickness
Thicker tape typically means additional durability and superior functionality in sealing and warmth resistance. Nevertheless, it might be harder to apply close to restricted corners.
four. UL Certification
For HVAC use, UL181A-P or UL181B-Forex certification makes certain the tape satisfies fireplace and protection standards.
5. Moisture & UV Resistance
Make sure the tape is ideal for outdoor use if required. UV foil tape and moisture resistance will avoid degradation after a while.
How to Apply Foil Tape Properly
Applying foil tape is easy, but a handful of most effective tactics assure utmost effectiveness:
Clear the Surface: Remove any Grime, oil, or humidity ahead of implementing the tape.
Measure & Slash: Pre-measure the size you should steer clear of squander.
Push Firmly: Utilize a squeegee or push Software to bond the tape securely to the area.
Overlap Edges: For ducts or seams, marginally overlap Each individual area for a good seal.
Avoid Stretching: Stretching foil tape can weaken the adhesive and compromise effectiveness.
