Aluminum foil layer: The water pipe insulation jacket features a layer of aluminum foil on the outer surface. This aluminum foil provides flame retardant properties, enhancing fire prevention. It also offers thermal insulation, improving waterproof and anti-freeze performance, which helps extend the service life of the pipeline. The aluminum foil layer is securely bonded to the rubber and plastic material, preventing shifting or peeling. Excellent thermal insulation effect: The outdoor pipe insulation wrap is constructed with 0.2-inch thick rubber-plastic cotton, delivering reliable thermal insulation, waterproofing, fire resistance, and weather resistance. It retains heat and protects outdoor pipes from freezing during winter. In summer, the aluminum foil helps shield water pipes from excessive heat and sunlight. It also effectively prevents cold water pipes from condensation and freezing. Strong self-adhesive design: The foam and foil pipe insulation tape has a strong adhesive backing. Simply remove the release liner and apply directly to the pipe. The tape adheres firmly and remains secure without loosening or slipping over time. Tip: Clean the pipe surface before application. Easy to install and remove: The duct wrap insulation tape is simple to handle—no residue left upon removal. It can be cut, torn, or peeled as needed. Provides enhanced fire protection, waterproofing, and anti-freeze benefits, contributing to longer pipeline durability. Dimensions: 2 inches wide x 0.2 inches thick x 32.8 feet long.
