Product Overview

The Jinqiang perforated acoustic calcium silicate board is a high-performance sound-absorbing material developed by Jinqiang Building Materials. Made from high-density calcium silicate board with precision perforations and an acoustic backing layer of non-woven fabric or fiberglass felt, it provides excellent mid-to-high frequency sound absorption while maintaining outstanding physical strength. This product features non-combustibility, moisture resistance, mold prevention, and decorative versatility, making it ideal for subway stations, airports, convention centers, schools, hospitals, theaters, and conference halls.

Structure & Acoustic Principle

• Calcium Silicate Base Board: High-density reinforced calcium silicate, processed via high-temperature autoclaving for excellent fire resistance and dimensional stability.

• Perforated Surface Layer: Available in various patterns (round, slotted, square, micro-perforations), with hole diameters from 6mm to 12mm and an open area ratio of 10%–20%.

• Acoustic Backing Layer: Covered with fiberglass felt or polyester fiber, effectively absorbs sound waves and reduces reflections.

Key Features

1. Excellent Acoustic Performance: NRC (Noise Reduction Coefficient) up to 0.85, suitable for speech-dominant environments.

2. A1 Grade Non-combustible: Fully compliant with national fire safety standards.

3. Moisture and Mold Resistant: Maintains stability in high-humidity environments.

4. High Strength & Durability: More impact-resistant than traditional acoustic panels.

5. Decorative Flexibility: Supports surface coating and customizable patterns/colors.

6. Eco-Friendly and Non-Toxic: Free from harmful substances; meets green building standards.

Installation Guidelines

Recommended to install with light steel or aluminum alloy framing systems. Ensure that the acoustic backing layer is installed simultaneously with the ceiling panels. Leave expansion joints (3–5mm) between boards. For wall applications, use aluminum clips or exposed framing systems. Installation should be performed by trained professionals to ensure safety and effectiveness.
