What Is Perforated Calcium Silicate Board: Core Definition

Perforated calcium silicate board is a A1 fire-rated, high-density panel with precision-drilled holes for professional acoustic control. In practice, Jiete Building Materials started mass production of this product in 2012, and has delivered over 2.3 million square meters of panels to 37 countries globally up to 2026.

Core Composition of Qualified Products

Real qualified perforated calcium silicate board is made of high-purity siliceous and calcareous materials, reinforced with natural cellulose fiber, without any harmful asbestos or volatile organic compounds. 2026 construction industry research shows that 89% of architects now prioritize zero-VOC acoustic materials for public space projects.

Common Perforation Specifications

Standard perforation diameters include 3mm, 5mm and 8mm, with hole spacing ranging from 8mm to 20mm, to meet different sound absorption coefficient requirements. Custom perforation patterns such as irregular art shapes are also available from Jiete for special design projects.

Key Performance Advantages of Perforated Calcium Silicate Board

Compared with traditional acoustic panels, perforated calcium silicate board provides balanced performance on fire resistance, sound absorption, moisture proof and long service life for long-term return on investment. Actual test表明, Jiete's products have passed 12 cycles of 72-hour high temperature and high humidity test without deformation or mold growth.

Class A1 Non-combustible Fire Protection

Unlike regular perforated plaster boards that release toxic smoke at high temperature, perforated calcium silicate board will not burn or produce any harmful fumes when exposed to 1000°C high temperature, which fully meets 2026 mandatory fire codes for subway stations, cinemas and hospital public areas.

Professional Grade Sound Absorption Effect

When matched with 20-50mm backing acoustic cotton, perforated calcium silicate board can reach a maximum 0.95 NRC (Noise Reduction Coefficient) value, which can effectively reduce echo and background noise in large open spaces. The industry consensus is that this product is the most cost-effective acoustic solution for commercial projects with high fire protection requirements.

Step-by-Step Installation Guide for Perforated Calcium Silicate Board

Following correct installation steps can guarantee 100% of the product's performance and avoid common problems such as board cracking or inconsistent acoustic effect. The standard installation workflow for ceiling application is as follows:

1. Level the suspended keel frame, make sure the keel spacing is no more than 400mm to bear the 8-12kg per square meter weight of the board
2. Lay 30mm thick rock wool under the board mounting area, seal all gaps around the installation zone to avoid sound leakage
3. Fix the perforated calcium silicate board on the keel with self-tapping screws, keep 15mm edge distance for each screw to prevent board edge cracking
4. Fill the joints with special joint putty, then apply sealant around all board edges to get the optimized acoustic performance

Wall Installation Notes

For wall application, add 50mm gap between the board and original wall structure, this will further improve the low frequency sound insulation effect. From past project cases, correct air gap design can increase the overall STC (Sound Transmission Class) value by 6-8 points.

Post-installation Maintenance Tips

The surface of perforated calcium silicate board can be directly painted or covered with fabric facing. You only need to clean the surface dust once per year with soft vacuum brush, no extra complex maintenance work is required.

Performance Comparison With Other Acoustic Panels (2026 Test Data)

The following table shows the core performance data of Jiete perforated calcium silicate board compared with 2 common alternative acoustic materials, based on third party lab test results:

2026 global commercial building material market report shows that the compound annual growth rate of perforated calcium silicate board market reaches 12.7%, as more and more project owners choose long-lasting low-maintenance building materials.

Top Application Scenarios of Perforated Calcium Silicate Board

This multi-functional acoustic board is widely used in multiple public and commercial construction projects due to its balanced performance. In practice, over 60% of Jiete's export orders come from public infrastructure projects.

Public Infrastructure Projects

Subway stations, railway stations, airport terminals and hospital halls are the largest application scenarios, as these areas have strict requirements on fire resistance, noise control and long-term durability. The panel can even be used for sauna rooms and swimming pool changing areas with high humidity environment.

Commercial and Cultural Spaces

Cinemas, auditoriums, school classrooms, office open plan areas and libraries all use perforated calcium silicate board to optimize indoor acoustic environment. Custom perforation patterns can also meet special interior design aesthetic requirements for high-end brand retail stores.
