Exactly what is Foil Tape?
Foil tape can be an adhesive tape made from aluminum foil or other metallic-centered resources, usually backed having a force-delicate adhesive (PSA). Its metallic Homes enable it to face up to Severe temperatures and resist humidity, UV mild, and substances. Mostly, foil tape is Utilized in HVAC units, insulation applications, and electrical repairs.
Unlike common duct tape, foil tape would not degrade after a while when subjected to heat or chilly. That makes it perfect for both of those indoor and outside purposes.
Popular Programs of Foil Tape
Foil tape is valued for its adaptability and efficiency below severe circumstances. Here are the commonest use circumstances:
one. HVAC Systems

one. Adhesive Strength
Glimpse for prime-tack adhesive that bonds instantaneously and forever. Some tapes use acrylic adhesive for lengthy-lasting maintain in Excessive temperatures.
2. Temperature Array
Select a tape with a wide operating temperature assortment, especially for HVAC or industrial use. Some tapes operate in ranges from -20°File to three hundred°File or better.
three. Thickness
Thicker tape frequently usually means extra toughness and greater functionality in sealing and heat resistance. However, it might be more challenging to use all-around restricted corners.
4. UL Certification
For HVAC use, UL181A-P or UL181B-Forex certification makes certain the tape fulfills fireplace and security specifications.
five. Moisture & UV Resistance
Make sure the tape is suitable for outside use if wanted. UV and dampness resistance will avoid degradation after a while.
How to Apply Foil Tape The right way
