Features

Product Overview

Fiberglass Acoustic Board is manufactured from chopped fiberglass using a wet-laid process. The controlled fiber structure forms a porous board that combines sound absorption, thermal insulation and fire-resistant performance.

Standard products are available in approximately 8–10 mm thickness. The board provides good stiffness while remaining lightweight, bendable and easy to cut, making it suitable for further processing and installation.

Its combination of acoustic, thermal and physical properties makes fiberglass acoustic board suitable for interior building materials and other applications where sound control and insulation performance are required.

Key Features

Sound Absorption

The porous fiberglass structure helps absorb sound across a wide frequency range, making the material suitable for acoustic treatment and noise-control applications.

Thermal Insulation

Fiberglass construction also provides thermal insulation performance, helping reduce heat transfer in building and interior systems.

Fire-Resistant Performance

The material has been evaluated according to the listed GB/T fire performance test methods, covering heat release, smoke generation, burning droplets and other indicators.

Lightweight and Easy to Process

Fiberglass Acoustic Board combines good stiffness with relatively low weight. It can be cut and further processed according to different installation and product requirements.

Custom Specifications

Unit weight, thickness, tensile strength, width, length and other specifications can be adjusted according to customer requirements.

Applications

Fiberglass Acoustic Board can be used in a wide range of acoustic and insulation environments, including:

Conference rooms and private offices
Training rooms and classrooms
Museums and libraries
Swimming pools and health clubs
Gymnasiums and public areas
Corridors and open-plan spaces
