Glass Wool Board – Premium Rigid Thermal Insulation & Sound Absorption Board

This professional glass wool board is designed for high-efficiency thermal insulation, noise reduction and fire protection in construction and industrial fields, delivering reliable performance and long service life.

Product Overview

Our glass wool board is a high-performance rigid insulation material made from high-purity glass fiber and eco-friendly binder through high-temperature hot pressing. This professional thermal insulation glass wool board features low thermal conductivity, superior sound absorption and Class A non-combustible performance, widely used for building exterior wall insulation, steel structure insulation, curtain wall filling and commercial industrial noise reduction projects, providing long-term energy-saving and fire safety protection for construction projects.

Key Features

  • Superb Thermal Insulation: Low thermal conductivity, effectively blocks heat transfer and reduces energy consumption of buildings.
  • Excellent Sound Absorption: Porous fiber structure significantly weakens noise transmission, ideal for soundproof scenarios.
  • Class A Non-combustible: Inorganic glass fiber material, zero flammability, meets strict fire protection standards.
  • Stable Dimensional Performance: Resists deformation, cracking and aging, suitable for long-term use in diverse environments.
  • Low Hygroscopicity: Good hydrophobic property, prevents mold growth and maintains performance stability.
  • Easy Construction: Can be cut freely with simple tools, high construction efficiency and low labor cost.
