As a result, we deliver factory-direct pricing, consistent acoustic performance, and fast delivery. Similarly, this applies to all your commercial, educational, and public interior projects.
In addition, we produce these concealed edge ceiling tiles from high-density fiberglass wool with a resin-bonded core. Meanwhile, they achieve an NRC of 0.90 for superior sound absorption and a CAC of 37dB for sound attenuation between rooms. Therefore, architects and interior designers rely on them for suspended ceiling systems where a seamless, monolithic ceiling surface is required.

Material & Acoustic Specifications for Conceal Edge Ceiling Tiles
- To begin with, we use high-density fiberglass wool as the standard core material. The resin-bonded fiberglass wool provides excellent sound absorption for our conceal edge ceiling panels.
- Moreover, our conceal edge ceiling tiles achieve an NRC of 0.90, making them a high-performance acoustic solution. A ceiling system with an NRC above 0.70 is considered high performance. CAC of 37dB ensures effective sound attenuation between adjacent rooms.
- Additionally, the Conceal Edge design completely hides the ceiling grid, creating an almost seamless suspended ceiling. The tiles are cut with precision and slot together to create a flushed, monolithic look[reference:1].
- Furthermore, our ceiling panels achieve a light reflectance of 0.88. This high light reflectance enhances conventional lighting and can reduce energy consumption.
- For special orders, we supply semi-concealed edge versions with a 1/4″ reveal for a semi-monolithic appearance, as well as aluminum foil backing to increase CAC where additional sound attenuation is required.
- Finally, we offer OEM & ODM — we customize tile size, thickness, density, edge type, surface finish, and packaging according to your project specifications.
NRC 0.90 & CAC 37dB — High Performance Acoustic Ceiling Solutions
In fact, NRC (Noise Reduction Coefficient) and CAC (Ceiling Attenuation Class) are the two most important acoustic performance metrics for ceiling tiles. Furthermore, understanding these ratings helps you select the right ceiling panel for your project.
To begin with, NRC 0.90 means our fiberglass ceiling panel absorbs 90% of the sound energy that strikes it. Meanwhile, this makes it ideal for reducing reverberation and echo in open-plan offices, lecture halls, and conference rooms. Then, CAC 37dB measures how effectively the ceiling prevents sound from traveling between adjacent rooms. Consequently, a CAC of 37dB provides good speech privacy between spaces. After that, the combination of high NRC and high CAC creates a balanced acoustic environment for speech clarity and privacy.
Therefore, our acoustic fiberglass ceiling panels are the material of choice for architects and acoustic consultants specifying ceiling systems for commercial and institutional buildings.
Key Advantages of Conceal Edge Acoustic Ceiling Panels
- First, the material offers NRC 0.90 for superior sound absorption, reducing reverberation and improving speech intelligibility.
- Second, CAC 37dB provides effective sound attenuation between adjacent rooms for speech privacy.
- Third, Class A fire rating ensures the lowest level of flame spread in emergency situations, making it a reliable choice for all applications.
- Finally, the Conceal Edge design completely hides the ceiling grid, creating a seamless, monolithic ceiling surface with no visible suspension components.
ASTM E1264 & EN 13964 — Standards Compliance for Ceiling Panels
In addition, our acoustic fiberglass ceiling panels comply with major international standards for ceiling systems. Furthermore, this ensures reliable performance and specification compliance across global projects.
- First, our ceiling panels meet ASTM E1264 for acoustical ceiling products. Materials classification is Type III (mineral fiber/fiberglass).
- Second, they comply with EN 13964 for suspended ceilings. This covers strength, safety, and performance requirements.
- Third, acoustic performance is tested to ASTM C423 (NRC) and EN ISO 11654 (sound absorption).
- Fourth, fire performance is tested to ASTM E84 (Class A) and EN 13501-1 (Euroclass A2-s1,d0).
- Finally, humidity resistance is verified to 99% RH, ensuring dimensional stability in humid environments.

How to Install Conceal Edge Acoustic Ceiling Panels
- First, install the suspension grid. Set up the concealed spline or clip-in grid system at the desired ceiling height. Ensure the grid is level and properly secured.
- Then, install edge moldings. Attach perimeter trim at the walls to conceal the edges of the border tiles.
- Next, install the ceiling panels. Slot each conceal edge tile into the concealed spline or clip-in grid. The precision-cut edges fit together to completely hide the grid.
- After that, cut border tiles as needed. Measure and cut edge tiles to fit the perimeter openings.
- Finally, check the installation. Ensure all tiles are properly seated, level, and aligned. The concealed edges should create a continuous, seamless ceiling surface with no visible grid.
