one. Adhesive Energy
Glance for prime-tack adhesive that bonds promptly and completely. Some tapes use acrylic adhesive for prolonged-lasting maintain in Severe temperatures.
2. Temperature Variety
Select a tape with a wide functioning temperature vary, specifically for HVAC or industrial use. Some tapes purpose in ranges from -20°F to three hundred°File or increased.
3. Thickness
Thicker tape usually means more longevity and superior effectiveness in sealing and heat resistance. However, it may be more durable to use close to tight corners.
four. UL foil tape Certification
For HVAC use, UL181A-P or UL181B-FX certification makes sure the tape fulfills fire and protection expectations.
5. Dampness & UV Resistance
Ensure the tape is well suited for outside use if needed. UV and humidity resistance will avoid degradation as time passes.
How to use Foil Tape Properly
Implementing foil tape is straightforward, but a handful of ideal practices assure highest performance:
Cleanse the Surface: Take away any dirt, oil, or dampness right before applying the tape.
Evaluate & Cut: Pre-measure the size you need to keep away from squander.
Press Firmly: Make use of a squeegee or push Software to bond the tape securely for the floor.
Overlap Edges: For ducts or seams, slightly overlap Every single portion for a tight seal.
Stay away from Stretching: Stretching foil tape can weaken the adhesive and compromise general performance.
