1. Adhesive Toughness
Glance for high-tack adhesive that bonds quickly and forever. Some tapes use acrylic adhesive for lengthy-Long lasting maintain in Intense temperatures.
two. Temperature Variety
Opt for a tape with a large working temperature assortment, especially for HVAC or industrial use. Some tapes perform in ranges from -20°F to 300°File or increased.
three. Thickness
Thicker tape normally indicates a lot more toughness and superior effectiveness in sealing and warmth resistance. Nonetheless, it may be more durable to use about limited corners.
4. UL Certification
For HVAC foil tape use, UL181A-P or UL181B-Forex certification makes certain the tape fulfills fireplace and basic safety criteria.
five. Dampness & UV Resistance
Ensure the tape is suitable for outside use if desired. UV and moisture resistance will protect against degradation after some time.
How to Apply Foil Tape Properly
Making use of foil tape is straightforward, but a couple of ideal methods make sure most performance:
Cleanse the Surface area: Remove any Filth, oil, or humidity prior to implementing the tape.
Evaluate & Cut: Pre-evaluate the duration you must avoid waste.
Press Firmly: Use a squeegee or push Instrument to bond the tape securely into the surface area.
Overlap Edges: For ducts or seams, a little bit overlap Just about every section for a tight seal.
Avoid Stretching: Stretching foil tape can weaken the adhesive and compromise efficiency.
Preferred Makes and The place to order
Numerous trusted models manufacture substantial-top quality foil tapes, including:
