Aluminum foil layer: There is a layer of aluminum foil on the surface of the water pipe insulation jacket. The flame retardant properties of aluminum foil can have a good fire prevention effect. It also has the function of thermal insulation, which improves the waterproof and anti-freeze effects and effectively extends the service life of the pipeline. The aluminum foil layer adheres closely to the rubber and plastic cotton and will not shift or fall off. Excellent thermal insulation effect: The outdoor pipe insulation wrap roll is made of 0.2-inch thick rubber-plastic cotton, which has good thermal insulation, waterproof, fireproof and weather-resistant properties. It can lock in heat and protect outdoor pipes from freezing in winter. In the summer, aluminum foil insulation can protect water pipes from the heat and sun. It can also effectively prevent cold water pipes from freezing or getting damp. Strong self-adhesive design: Foam and foil tube wrapped insulation tape has strong adhesive on the back. Simply peel off the film backing and tape onto the outer tube. The tape will stick firmly to the pipe and will not loosen or shift even over time. Tip: Clean the pipe surface before applying the tape. Easy to remove: Duct wrap insulation tape is very easy to install and remove. No residue, cutting, tearing, peeling. It can provide fire protection for pipelines, improve waterproof and antifreeze effects, and effectively extend the service life of pipelines.
