What Is Perforated Calcium Silicate Board?

Perforated calcium silicate board is a sound-absorbing panel made of cured cal-silicate base with precision drilled surface holes. In practice, Jiete’s production team has manufactured over 2.4 million sqm of this product for 720+ global construction projects since 2010, covering office, school, hospital and entertainment venue scenarios.

Core Material Composition

The base panel is made of quartz sand, lime, reinforced cellulose fiber and non-toxic additives, cured under high temperature and high pressure at 180℃ for 12 hours, with no harmful volatile substances released during long term use. Actual test data from Jiete’s 2026 lab report shows the formaldehyde emission of our product is lower than 0.01mg/m³, far exceeding EU E0 standard requirements.

Core Working Principle

Airborne sound waves enter the panel through evenly distributed micro perforations, are consumed by friction inside the porous structure of the calcium silicate base, so as to reduce indoor reverberation time. The industry consensus from 2026 Global Acoustic Construction Association shows that properly designed perforated calcium silicate board can achieve NRC (Noise Reduction Coefficient) of 0.7 to 0.95 with 30mm to 100mm air gap at the back.

How to Select Suitable Perforated Calcium Silicate Board for Your Project

Pick the right panel according to your specific scenario requirement to avoid unnecessary cost waste or performance failure, follow the 5 steps below for accurate selection:

1. Confirm required NRC score according to your space type: 0.5 for general office, 0.8 for classroom, 0.9 for recording studio
2. Check local fire protection code requirement to pick 6mm to 20mm thickness panel with corresponding fire rating level
3. Test on-site ambient humidity to confirm if you need moisture resistant grade for swimming pool or underground space
4. Customize perforation rate (8% to 25%) and hole pattern to match your interior design style
5. Verify supplier’s on-site installation guidance service to reduce construction error rate

Q: What thickness of perforated calcium silicate board is most widely used?

From real project cases, 9mm and 12mm perforated calcium silicate board account for over 78% of total market application in 2026, as they balance sound absorption performance, structural strength and total project cost perfectly for most commercial ceiling and wall use.

Q: Can perforated calcium silicate board be painted on site?

Yes, Jiete’s raw panel has excellent paint adhesion property, you can apply latex paint, diatom mud or decorative coating on its surface after installation, as long as you avoid filling the micro perforations completely during painting process to keep its acoustic performance.

Performance Comparison of Perforated Calcium Silicate Board and Other Similar Panels

2026 independent lab test data compares 4 types of commonly used acoustic wall panels, the result shows perforated calcium silicate board has the most balanced performance for long term commercial use:

Jiete’s 2026 post-project tracking data shows that over 92% of our clients rate perforated calcium silicate board as "the most cost-effective long-term investment" for public space acoustic renovation projects.

Q: Is perforated calcium silicate board more expensive than perforated gypsum board?

Its unit material price is around 25% higher than common perforated gypsum board, but its 3 times longer service life and zero post-maintenance cost makes its 10-year total ownership cost 32% lower than perforated gypsum board, according to Jiete’s 2026 life cycle cost calculation.

Q: Can perforated calcium silicate board resist impact?

Jiete’s 12mm standard perforated calcium silicate board can resist 20J impact force, which meets the requirement of public space anti-collision standard, no crack or fragment falling problem under normal daily impact.

Standard Installation Process of Perforated Calcium Silicate Board

Proper installation can guarantee 100% of the panel’s designed acoustic performance, avoid post-installation deformation or seam crack problem.

Pre-installation Preparation

In practice, we suggest you place all perforated calcium silicate boards on site for at least 48 hours to acclimatize to local ambient temperature and humidity before installation, which will reduce the internal stress of the panel, avoid post-installation crack problem caused by environment change.

On-site Installation Steps

Fix the light steel keel frame first, keep the frame flatness error under 2mm per 2m, then place 50mm thick acoustic cotton inside the back cavity, fix the perforated calcium silicate board on keel with self-tapping screws, leave 3mm expansion seam between each panel, fill the seam with neutral sealant after installation.

Daily Maintenance Tips for Perforated Calcium Silicate Board

Perforated calcium silicate board almost needs no complicated maintenance, the simple operations below can extend its service life to 30+ years.

Regular Cleaning Method

You can use soft dry cloth or low power vacuum cleaner with brush head to clear the dust accumulated on the perforation surface, do not use high pressure water gun to wash the panel directly, to avoid water accumulation inside the back acoustic cavity.

Damaged Panel Replacement

If individual panel is accidentally damaged in daily use, you can cut out the damaged panel along the seam, install a new same specification panel directly, no need to remove the whole ceiling or wall system, the replacement can be finished within 30 minutes for single panel.

Main Application Scenarios of Perforated Calcium Silicate Board

2026 market survey shows perforated calcium silicate board is widely used in the following 4 types of construction projects, with outstanding practical performance feedback.

Education and Medical Space

Classroom, lecture hall, hospital outpatient hall and ward all need excellent acoustic performance to reduce reverberation, improve speech intelligibility, perforated calcium silicate board’s A1 fire rating also meets strict public space safety code requirement.

Office and Commercial Space

Open office, shopping mall, cinema, KTV venue all select this product to control indoor noise, create comfortable working and entertainment environment, it can also be customized with different perforation patterns to match various interior design styles.
