Vital Features to Look for in Foil Tape
When picking foil tape for the job, keep the following criteria in mind to make sure it performs as expected:

1. Adhesive Strength
Look for high-tack adhesive that bonds immediately and permanently. Some tapes use acrylic adhesive for lengthy-lasting keep in Excessive temperatures.

2. Temperature Variety
Pick a tape with a wide operating temperature range, specifically for HVAC or industrial use. foil tape Some tapes perform in ranges from -twenty°File to 300°F or higher.

three. Thickness
Thicker tape frequently usually means extra toughness and superior general performance in sealing and warmth resistance. Even so, it may be harder to foil tape use all around tight corners.

four. UL Certification
For HVAC use, UL181A-P or UL181B-FX certification guarantees the tape satisfies hearth and safety benchmarks.

5. Moisture & UV Resistance
Make sure the tape is ideal for out of doors use if wanted. UV and dampness resistance will prevent degradation eventually.

How to Apply Foil Tape Correctly
