Izocam 1 1/4 Inch (42 mm) Glass Wool Prefabricated Pipe | Pipe Insulation

What Is Izocam 1 1/4 Inch (42 mm) Glass Wool Prefabricated Pipe? Where Is It Used?

The Izocam 1 1/4 Inch (42 mm) Glass Wool Prefabricated Pipe is a high-density glass wool pipe insulation product designed for thermal insulation in industrial and mechanical piping systems. In addition to reducing heat loss, it helps protect pipelines against condensation and freezing while also improving acoustic and vibration insulation.

Available in unfaced and aluminum foil-faced versions, this insulation solution is widely used in central heating systems, industrial pipelines, and solar energy installations to minimize heat loss and maintain maximum system efficiency.

Applications

The 1 1/4 inch (42 mm) nominal diameter prefabricated pipe insulation is suitable for:

  • Thermal insulation of industrial piping systems
  • Radiator and central heating installations
  • Solar energy piping systems
  • Pipelines requiring condensation protection
  • Freeze protection for pipe networks
  • Acoustic and vibration insulation for pressurized water pipelines

Installation Instructions

Before installation, select the 1 1/4 inch (42 mm) prefabricated pipe insulation that matches the pipe's nominal diameter.

  • Open the insulation along its factory-cut slit and place it over the pipe.
  • Complete the installation by ensuring all joints are tightly closed without gaps.

For Unfaced Products

The exterior surface may be protected with:

  • Bitumen emulsion
  • Bituminous membrane
  • Galvanized metal jacketing
  • Aluminum cladding

The protective covering can be secured using adhesive bonding, lock-seaming, riveting, or screws.

For Aluminum Foil-Faced Products

  • The self-adhesive overlap flap simplifies installation.
  • Seal all joints with self-adhesive aluminum foil tape at least 75 mm (7.5 cm) wide.
  • This creates an effective vapor barrier that prevents moisture penetration.

For double-layer installations, stagger the joints between layers, ensuring the final layer's joint is positioned on the underside of the pipe whenever possible.

Product Advantages

  • Excellent thermal insulation performance
  • Enhanced fire safety
  • Fast and easy installation
  • Helps reduce noise and vibration
  • Flexible installation options with unfaced and foil-faced versions
