Used for sealing fiberglass duct board

Tear-resistant and suited to heavy-obligation jobs

Important Characteristics to search for in Foil Tape
When deciding upon foil tape for a undertaking, hold the subsequent requirements in your mind to be certain it performs as envisioned:

one. Adhesive Energy
Glimpse for top-tack adhesive that bonds quickly and completely. Some tapes use acrylic adhesive for extended-lasting maintain in Extraordinary temperatures.

2. Temperature Array
Choose a tape with a wide operating temperature vary, specifically for HVAC or industrial use. Some tapes functionality in ranges from -twenty°F to 300°File or better.

three. Thickness
Thicker tape commonly usually means extra longevity and superior performance in sealing and warmth resistance. Having said that, it could be more challenging to apply about 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
Make sure the tape is ideal for outdoor use if desired. UV and dampness resistance will stop degradation as time passes.

How to use Foil Tape Appropriately
Applying foil tape is easy, but several very best tactics be certain most performance:

Clean the Area: Take away any Dust, oil, or dampness ahead of making use of the tape.

Evaluate & Slash: Pre-evaluate the length you must avoid squander.

Press Firmly: Make use of a squeegee or push Software to bond the tape securely into the area.

Overlap Edges: For ducts or seams, a bit overlap Each and every area for a tight seal.

Avoid Stretching: Stretching foil tape can weaken the adhesive and compromise functionality.

Well-known Makes and The place to obtain
Numerous reliable models manufacture large-excellent foil tapes, including:

3M – Known for industrial-grade and UL-Licensed tapes

Nashua – Common for HVAC and insulation apps
