This premium-grade aluminum foil tape offers excellent thermal conductivity, enhancing heating or cooling efficiency. It acts as a waterproof barrier and protects against air leaks. The tape has an acrylic adhesive on an aluminum backing. It's flame-resistant, reflects heat and light, and magnifies light sources for better visibility. It resists ultraviolet degradation for long-lasting performance and meets UL 723, Class L File R 7311, and UL 764c standards.

Using this aluminum foil tape is easy. First, clean the surface where you want to apply the tape to ensure it's dry and free of dust and grease. Then, carefully unroll the tape and cut it to the desired length. Press the tape firmly onto the surface, smoothing out any bubbles as you go. When using it for heating or cooling systems, make sure to seal all joints and seams properly for maximum efficiency. As for maintenance, this tape is designed to resist ultraviolet degradation, so it can last a long time outdoors. However, if it gets dirty, you can gently wipe it with a damp cloth. Just avoid using harsh chemicals or abrasive materials that could damage the tape. Also, store the tape in a cool, dry place when not in use to keep it in good condition.
