3M 7000028867 Glass Cloth Tape 2in 36yd Silver Aluminum

Product Description

The 3M 7000028867 is a glass cloth tape with an aluminum foil facing, designed for heat-reflecting and high-temperature insulation applications in commercial and industrial settings. Part of the 3M Series 363 line, it measures 2 inches wide and 36 yards long with a 7.3 mil total thickness. The aluminum construction delivers a tensile strength of 135 pounds per inch, making it suitable for wrapping, sealing, and securing thermal insulation on ductwork, piping, and other surfaces exposed to elevated operating temperatures. HVAC technicians, sheet metal workers, and insulation contractors are the primary installers.

This tape is well suited for heat-reflecting applications on duct systems, mechanical insulation jacketing, and equipment wrap where operating temperatures can reach extremes. It is rated for continuous service from -65.2 degrees F to 600 degrees F, covering the full range of temperatures encountered in commercial HVAC duct systems, boiler room piping, and industrial process equipment. Its compliance with F.A.R. 25.853(a) also makes it appropriate for aerospace and aviation maintenance environments requiring flame-resistant materials.

Key Features

• Aluminum facing provides effective heat reflection for insulated duct and pipe systems
• 135 lb per inch tensile strength resists tearing during application and in service
• Wide operating range from -65.2 degrees F to 600 degrees F suits extreme-temperature environments
• 7.3 mil thickness adds durability without excessive bulk on wrapped surfaces
• Meets F.A.R. 25.853(a) flame-resistance standard for aviation and industrial use
• 2 inch width and 36 yard roll length minimize splices on long duct or pipe runs

Compatibility

Designed for use as a heat-reflecting and insulation jacketing tape on commercial HVAC ductwork, mechanical piping insulation, and industrial equipment requiring high-temperature resistance up to 600 degrees F.

Installation Notes

Installation is typically performed by HVAC technicians, insulation contractors, or sheet metal workers. Surfaces should be clean, dry, and free of oils or loose debris before tape application to ensure full adhesive contact. When used on duct systems, follow applicable SMACNA standards and local mechanical codes for insulation and sealing requirements. Do not exceed the rated maximum operating temperature of 600 degrees F.
