two. Temperature Assortment
Pick a tape with a large running temperature array, specifically for HVAC or industrial use. Some tapes purpose in ranges from -20°F to three hundred°File or increased.
3. Thickness
Thicker tape typically implies a lot more durability and better overall performance in sealing and warmth resistance. Having said that, it might be more difficult to use all around tight corners.
four. UL Certification
For HVAC use, UL181A-P or UL181B-FX certification ensures the tape fulfills fire and security requirements.
five. Dampness & UV Resistance
Ensure the tape is foil tape suited to outside use if needed. UV and humidity resistance will avoid degradation as time passes.
How to use Foil Tape Appropriately
Applying foil tape is simple, but a couple of most effective procedures ensure utmost efficiency:
Clean the Floor: Eliminate any Filth, oil, or moisture ahead of implementing the tape.
Measure & Slice: Pre-measure the size you might want to keep away from squander.
Press Firmly: Make use of a squeegee or push tool to bond the tape securely for the area.
Overlap Edges: For ducts or seams, somewhat overlap Just about every section for a good seal.
Prevent Stretching: Stretching foil tape can weaken the adhesive and compromise overall performance.
