In modern architecture and interior design, acoustics have become one of the core factors influencing the quality and comfort of a space. As cities grow denser and work environments become increasingly collaborative, the need for quiet, focused, and comfortable interiors has never been greater. This is where ceiling materials—particularly those with high sound absorption performance—play a crucial role. One of the most important acoustic indicators for ceiling materials is the Noise Reduction Coefficient (NRC).
NRC, or Noise Reduction Coefficient, measures how much sound a material absorbs instead of reflecting it back into the room. The scale ranges from 0.00 to 1.00.
NRC = 0.00 means total sound reflection (like a concrete wall).
NRC = 1.00 means total sound absorption (no echo).
For example, a ceiling tile with an NRC of 0.70 absorbs 70% of the sound and reflects only 30%. In real-world scenarios, that means when noise levels in an office reach 70 decibels, ceiling materials with an NRC of 0.70 can reduce the sound level to around 49 decibels, creating a more peaceful environment comparable to normal conversation levels.
Materials with NRC ≥ 0.50 are typically categorized as high-performance acoustic materials, capable of significantly improving speech clarity, reducing echo, and increasing the comfort of occupants.
In today’s building design, acoustic comfort is not a luxury—it’s a necessity. Poor sound control can lead to stress, fatigue, and communication difficulties, especially in shared spaces such as offices, schools, hospitals, and public institutions. Studies show that effective acoustic materials can improve employee concentration by up to 48%, reduce stress-related fatigue by 27%, and enhance overall comfort and satisfaction in interior environments.
At Kente Building Materials, we believe that architectural beauty and functionality must coexist. Our product portfolio includes Mineral Wool Boards, Fiberglass Boards, PVC Gypsum Boards, and Polyester Fiber Ceilings—each designed to address specific acoustic, thermal, and aesthetic needs.
Our Mineral Wool Board and Fiberglass Board products are especially renowned for their superior acoustic performance, achieving NRC values between 0.65 and 0.75. These materials feature a micro-porous structure that effectively absorbs mid- and high-frequency sound waves, reducing reverberation and improving speech intelligibility.
The PVC Gypsum Board, on the other hand, offers a perfect combination of acoustic balance and decorative finish, making it suitable for environments where design and cleanliness are equally important—such as hospitals, shopping malls, and hotels.
Meanwhile, Polyester Fiber Ceiling Panels represent the next generation of sustainable building materials. Made from eco-friendly polyester fibers, they are lightweight, recyclable, and non-toxic, providing excellent sound absorption with an NRC rating up to 0.80, while also contributing to indoor air quality and green building certifications.
Headquartered in Hejin, Shanxi Province, Kente Building Materials has been committed to creating high-performance ceiling systems since its establishment. As a modern building materials enterprise integrating R&D, design, sales, and service, Kente has built a reputation for quality, innovation, and sustainability.
With seven production bases across China, our company utilizes intelligent manufacturing technology, precise process control, and continuous research and development to ensure that every ceiling tile meets the highest international standards. Kente has obtained ISO certification for its mineral fiber ceiling products, proving both product reliability and management excellence.
Our corporate philosophy, “Healthy Life, Smart Future,” guides everything we do. From raw material sourcing to finished product inspection, we emphasize green production, efficient energy use, and sustainable development, helping our partners create safer, more comfortable, and environmentally responsible spaces.
Each architectural environment demands a different level of sound absorption. Kente provides customized ceiling system solutions to meet the acoustic and aesthetic needs of diverse projects:
Commercial Offices: High NRC mineral wool or fiberglass ceilings help minimize noise from telephones, printers, and human conversation, fostering a focused work atmosphere.
Educational Institutions: Classrooms, libraries, and lecture halls benefit from ceiling materials with NRC ≥ 0.70, ensuring clear communication and concentration.
Healthcare Facilities: Hospitals and clinics rely on ceilings that reduce ambient noise and promote patient recovery; polyester fiber ceilings are ideal for these settings.
Industrial Plants: In large industrial spaces, Kente’s acoustic ceilings help reduce machinery noise and create a safer, more productive working environment.
Residential and Public Buildings: PVC Gypsum Boards and Mineral Wool Boards balance aesthetics and functionality, providing homeowners and designers with durable, easy-to-install ceiling solutions.
Since its founding, Kente has evolved from a domestic brand into an international leader in ceiling system solutions. In 2022, the company established its International Business Department, and by 2023, Kente’s products had been exported to over 60 countries worldwide, including markets in Europe, the Middle East, Southeast Asia, and South America.
Our ceiling materials are trusted by architects, contractors, and developers in various large-scale projects such as office towers, shopping centers, government buildings, and educational institutions. This global trust reflects Kente’s consistent pursuit of innovation, performance, and integrity.
Selecting the ideal ceiling tile depends on both the acoustic goals and visual design of your project:
For offices and classrooms, choose Mineral Wool Boards or Fiberglass Boards with NRC ≥ 0.65 for maximum sound absorption.
For healthcare and hospitality, opt for Polyester Fiber Ceilings, which combine acoustic performance with hygiene and sustainability.
For decorative and functional commercial spaces, PVC Gypsum Boards provide a sleek appearance and moderate sound control at an economical cost.
By analyzing your project’s size, layout, and function, Kente’s technical team can help customize a complete ceiling system solution that meets both acoustic performance standards and aesthetic requirements.
At Kente, we are not just a ceiling manufacturer—we are a solution provider for the modern built environment. Our ongoing mission is to contribute to the green and sustainable development of the global building materials industry, continuously optimizing sound absorption technology, improving indoor air quality, and reducing environmental impact.
