Product Overview
The perforated acoustic cement panel is a high-performance acoustic and decorative board made from reinforced fiber cement, precisely perforated and backed with sound-absorbing materials. It integrates sound absorption, fire resistance, moisture resistance, durability, and visual appeal—delivering both acoustic functionality and architectural reliability. This panel is widely used in subways, airports, convention centers, tunnels, stadiums, auditoriums, schools, and other large-scale public buildings. It is an ideal choice for modern acoustic control and decorative applications.
Structure and Acoustic Principle
Base Layer: High-density fiber-reinforced cement board with excellent rigidity, high strength, and superior fire resistance.
Perforation Design: Acoustically calculated perforations (round, slotted, square), with a typical open area ratio of 10%–20% to allow efficient sound wave penetration.
Backing Material: High-density fiberglass mat, mineral wool mat, or non-woven acoustic backing for effective sound energy absorption.
Composite System: The “micro-perforation + rear cavity” structure achieves an NRC (Noise Reduction Coefficient) of 0.6–0.85, especially effective in the mid-to-high frequency range.
Key Features and Advantages
Excellent Sound Absorption: Engineered for 500Hz–4000Hz frequency ranges, ideal for speech-dominant environments.
High Strength & Impact Resistance: Cement-based core delivers rigidity and resistance to compression and impact.
A1-Level Non-Combustibility: Fully meets A1 fire safety standards, making it suitable for high-safety construction projects.
Superior Weather Resistance: Performs reliably under high humidity and temperature variations without warping or mildew.
Decorative Versatility: Surface supports spraying and pattern customization to meet design needs.
Eco-Friendly & Low-Carbon: Asbestos-free and formaldehyde-free, compliant with green building standards.
Application Scenarios
Transport Infrastructure: Subway stations, high-speed rail terminals, airport waiting areas, tunnel walls and ceilings.
Exhibition & Conference Spaces: Convention centers, auditoriums, lecture halls, conference centers.
Educational & Medical Facilities: Classrooms, laboratories, libraries, hospital corridors and consultation areas.
Entertainment & Sports Venues: Theaters, concert halls, gyms, rehearsal rooms, cinemas.
Commercial & Industrial Areas: Shopping malls, industrial plants, office zones requiring acoustic and structural integration.
Installation Guidelines
Installation methods include:
Exposed or concealed frame systems for easy removal and maintenance.
Metal clip-back systems for wall and ceiling integration.
Expansion gaps between panels to prevent thermal deformation.
Ensure stable, level base before installation; professional installers are recommended.
Technical & Service Support
We offer a wide range of standard models, with full support for custom perforation patterns, dimensions, and backing configurations. Technical drawings, acoustic simulations, and deep engineering services are available to help you achieve the ideal balance between design and performance.
