Used for sealing fiberglass duct board

Tear-resistant and appropriate for significant-responsibility tasks

Crucial Capabilities to search for in Foil Tape
When selecting foil tape for any job, continue to keep the following criteria in mind to make certain it performs as anticipated:

1. Adhesive Power
Search foil tape for top-tack adhesive that bonds instantaneously and completely. Some tapes use acrylic adhesive for prolonged-lasting maintain in Excessive temperatures.

2. Temperature foil tape 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 greater.

three. Thickness
Thicker tape frequently usually means additional toughness and greater effectiveness in sealing and heat resistance. Nonetheless, it may be more durable to use close to tight corners.

four. UL Certification
For HVAC use, UL181A-P or UL181B-FX certification ensures the tape satisfies hearth and security requirements.

five. Dampness & UV Resistance
Make sure the tape is ideal for outdoor use if needed. UV and dampness resistance will stop degradation over time.

How to use Foil Tape Properly
Implementing foil tape is straightforward, but a handful of ideal methods be certain greatest overall performance:

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

Measure & Slice: Pre-evaluate the size you might want to stay away from squander.

Push Firmly: Use a squeegee or press Software to bond the tape securely for the area.

Overlap Edges: For ducts or seams, somewhat overlap Just about every section for a good seal.

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

Well-liked Makes and Where to get
Quite a few dependable brand names manufacture significant-quality foil tapes, which includes:

3M – Recognized for industrial-grade and UL-Accredited tapes

Nashua – Well known for HVAC and insulation purposes
