Used for sealing fiberglass duct board

Tear-resistant and appropriate for significant-responsibility responsibilities

Important Functions to Look for in Foil Tape
When picking out foil tape for just a venture, preserve the next requirements in mind to be sure it performs as anticipated:

one. Adhesive Strength
Search for prime-tack adhesive that bonds quickly and completely. Some tapes use acrylic adhesive for prolonged-Long lasting maintain in Severe temperatures.

2. Temperature Assortment
Pick a tape with a wide operating temperature variety, especially for HVAC or industrial use. Some tapes functionality in ranges from -twenty°File to 300°F or higher.

three. Thickness
Thicker tape commonly suggests additional toughness and superior performance in sealing and warmth resistance. On the other hand, it might be more difficult to apply all-around limited corners.

four. UL Certification
For HVAC use, UL181A-P or UL181B-Forex certification assures the tape meets fireplace and safety benchmarks.

five. Dampness & UV Resistance
Ensure the tape is ideal for outdoor use if required. UV and dampness resistance will reduce degradation eventually.

How to Apply Foil Tape Properly
Implementing foil tape is simple, but a few finest methods be certain greatest overall performance:

Clean up the Surface area: Take out any Grime, oil, or humidity just before implementing the tape.

Evaluate & Reduce: Pre-evaluate the size you need to prevent waste.

Press Firmly: Make use of a squeegee or push Instrument to bond the tape securely to your surface.

Overlap Edges: For ducts or seams, a bit overlap each area for a decent seal.

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

Preferred Brand names and The place to obtain
Numerous trustworthy makes manufacture superior-top quality foil tapes, which include:
