Product Introduction

The glass wool blanket, a processed version of glass wool, is a rectangular panel offered in various densities. After production as a semi-finished glass wool product, it undergoes polishing, spraying, and adhesion. Primarily used for insulation, it boasts an average fiber diameter of around 7 μm, meeting thermal insulation needs cost-effectively. Available with or without veneer, its lightweight, durable, and flexible nature allows for application on irregular surfaces. This effectively conserves energy, reduces heat loss, and cuts operational costs.

Feature:

  • Environmentally friendly.
  • Energy-saving.
  • Easy to cut, handle, and install.
  • Euro fire classification: A1.
  • No health hazards, asbestos-free.
  • Outstanding thermal and acoustic insulation.
  • Stable physical and chemical properties.

Application:

  • Thermal insulation, heat insulation, sound absorption, and noise reduction for building exterior walls.
  • Insulation for industrial furnaces.
  • Interlayer insulation for steel insulation boards.
  • Noise reduction in generator rooms and pump rooms.
  • Maintaining constant temperature in computer rooms and refrigerators.
