3M 7000001165 Glass Cloth Tape 1 in 36 Yd Silver Aluminum

Product Description

The 3M 7000001165 is a Series 363 aluminum-backed glass cloth tape designed for heat-reflecting and high-temperature applications. The tape measures 1 inch wide and 36 yards long with a thickness of 7.3 mil. It carries a tensile strength of 135 pounds per inch, making it durable under mechanical stress in demanding service environments. The aluminum facing reflects radiant heat while the glass cloth backing provides dimensional stability. It is rated for continuous use from -65.20 degrees F to 600 degrees F, covering a wide range of operating conditions. HVAC technicians, sheet metal workers, and insulation contractors are the primary installers of this product.

This tape is suited for duct insulation facing, pipe wrap, and heat-shield applications in both residential and commercial HVAC systems. It meets F.A.R. 25.853(a) standards, indicating suitability for flame-resistant applications where regulatory compliance is required. Typical use cases include sealing and securing foil-faced duct insulation, wrapping exhaust components, and providing a reflective barrier on high-heat surfaces. The 36-yard roll length reduces the need for mid-job roll changes on larger installations.

Installation Notes

Installation is typically performed by HVAC technicians, sheet metal workers, or insulation contractors. Surfaces should be clean, dry, and free of dust or oil before application to ensure full adhesive contact. When working near energized equipment or hot surfaces, de-energize systems and allow components to cool to a safe handling temperature before applying tape. Follow local mechanical and building codes for duct sealing and insulation requirements.
