Seem for prime-tack adhesive that bonds promptly and forever. Some tapes use acrylic adhesive for extensive-Long lasting keep in Serious temperatures.
two. Temperature Array
Decide on a tape with a broad functioning temperature range, specifically for HVAC or industrial use. Some tapes functionality in ranges from -twenty°F to 300°F or higher.
3. Thickness
Thicker foil tape tape commonly usually means more durability and much better functionality in sealing and heat resistance. Even so, it might be more foil tape difficult to apply close to tight corners.
four. UL Certification
For HVAC use, UL181A-P or UL181B-FX certification guarantees the tape meets fireplace and basic safety specifications.
5. Humidity & UV Resistance
Ensure the tape is ideal for out of doors use if wanted. UV and dampness resistance will avoid degradation as time passes.
How to use Foil Tape Effectively
Making use of foil tape is straightforward, but a handful of ideal methods ensure most effectiveness:
Thoroughly clean the Area: Take away any dirt, oil, or humidity just before implementing the tape.
Measure & Slash: Pre-measure the duration you should avoid waste.
Push Firmly: Use a squeegee or press Software to bond the tape securely for the area.
Overlap Edges: For ducts or seams, marginally overlap Each individual segment for a decent seal.
