As a result, we deliver factory-direct pricing, consistent acoustic performance, and fast delivery. Similarly, this applies to all your commercial, educational, healthcare, and corporate interior projects.

In addition, we produce these semi concealed 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 contractors rely on them for suspended ceiling systems where a subtle shadowline reveal is preferred over a fully exposed or fully concealed grid.

Technical Specifications of Semi Concealed Edge Acoustic Fiberglass Ceiling Panels

To begin with, we manufacture our semi concealed ceiling panels in a range of sizes and thicknesses. Specifically, the table below summarizes the standard product range.

Material & Acoustic Specifications for Semi Concealed 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 semi concealed ceiling panels.
• Moreover, our semi concealed 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 Semi Concealed Edge design features a small step or groove along the tile edge that partially hides the grid. This creates a narrow shadowline reveal, giving a cleaner, more refined appearance than a square edge, while remaining easier to install and remove than a fully concealed system.
• Furthermore, the semi concealed edge retains full plenum access. You can lift individual tiles out of the grid for maintenance without special tools.
• For special orders, we supply 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, classrooms, 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 Semi Concealed 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.
• Finally, the Semi Concealed Edge design creates a narrow shadowline reveal that hides part of the grid for a cleaner look, while keeping the ceiling fully demountable for plenum access.

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, grid installation follows ASTM C636 for metal ceiling suspension systems.
• Fourth, acoustic performance is tested to ASTM C423 (NRC) and EN ISO 11654 (sound absorption).
• Finally, fire performance is tested to ASTM E84 (Class A) and EN 13501-1 (Euroclass A2-s1,d0).

Why Choose Our Semi Concealed Edge Acoustic Ceiling Panels?

• For example, our ceiling panels offer NRC 0.90 Acoustic Performance. Superior sound absorption for open-plan offices, classrooms, and conference rooms.
• In addition, they provide CAC 37dB Sound Attenuation. Effective sound blocking between adjacent rooms for speech privacy.
• Moreover, they feature Class A Fire Rating. Meets ASTM E84 with flame spread of 25 or less and smoke development of 50 or less.
• Furthermore, they ensure Semi Concealed Edge Shadowline Design. The semi concealed edge creates a narrow shadowline reveal that partially hides the grid for a clean, modern appearance while retaining full plenum access.
• As a result of their High Light Reflectance (0.88), they enhance conventional lighting and reduce energy consumption.
• Finally, we provide Direct Factory Support. Tarco Industry provides technical guidance, samples, and custom production.

How to Install Semi Concealed Edge Acoustic Ceiling Panels

1. First, install the suspension grid. Set up the 15/16″ or 9/16″ exposed tee grid system at the desired ceiling height, per ASTM C636. Ensure the grid is level and properly secured.
2. Then, install edge moldings. Attach perimeter trim at the walls to support border tiles.
3. Next, place the ceiling panels. Tilt each semi concealed edge tile and insert it into the grid opening. The semi concealed edge rests on the grid flange and creates a narrow shadowline reveal along the tile edge.
4. After that, cut border tiles as needed. Measure and cut edge tiles to fit the perimeter openings.
5. Finally, check the installation. Ensure all tiles are properly seated, level, and aligned. The semi concealed edge should create a consistent narrow shadowline around each tile. Tiles can be lifted out for above-ceiling access.
