Product Introduction

The Glass Wool Board is a processed form of glass wool, presenting as a rectangular panel with variable densities. Crafted from semi-finished glass wool products, it undergoes polishing, spraying, and adhesion. Primarily used for insulation, its fibers boast an average diameter of 7 μm, meeting thermal needs economically. Available with or without veneer, it’s lightweight, durable, and adaptable to irregular surfaces. This enables efficient energy conservation, heat loss reduction, and operational cost savings.

Feature:

  • High acoustic absorption and low heat conductivity coefficients.
  • Waterproof and corrosion-resistant.
  • Resistant to mildew and pests, effectively preventing condensation and pipe freezing.
  • Lightweight, flexible, and easy to transport and install.
  • Maintenance-free.
  • Long-lasting and resistant to aging.

Application:

  • Steel structure building heat preservation.
  • Energy-saving heat insulation for house walls and roofs.
  • Indoor partition walls, train compartments.
  • Fireproofing, heat resistance, and sound insulation for cooling and tall buildings.
