- Designed to fit standard drop ceiling tiles (24″ x 24″ or 24″ x 48″)
- Built with rigid fiberglass for broadband sound absorption
- Class A fire-rated for safe commercial and residential use (tested to ASTM E84 standards)
- Available in 9 GIK standard fabric colors or upgrade to Guilford of Maine
- Handcrafted in the USA for premium quality and performance
- Available with or without a fabric finish
These panels are a great upgrade from traditional mineral fiber or PVC ceiling tiles, which do little to improve room acoustics in critical audio rooms.Our panels are designed to absorb sound waves across a much wider frequency range, eliminating unwanted echoes and reducing overall room noise along with improving the sound for more critical audio applications.
Where to Use Acoustic Ceiling Panels
Our acoustic ceiling tiles are perfect for any space with a lay-in ceiling system:
- Offices and conference rooms for improved clarity during calls and meetings
- Home theaters and listening rooms to enhance audio playback and reduce reverberation
- Recording studios and mix rooms for better sound isolation and control
- Classrooms and libraries for more productive learning environments
- Retail environments and restaurants for improved ambiance and noise control
Installing these panels into an existing ceiling grid is fast and easy, with no special tools required. Just remove your existing ceiling tiles and drop in our sound-absorbing panels. Each unit is designed for optimal functionality in standard ceiling grid systems, making them an ideal retrofit option.
Why Our Ceiling Panels Make a Difference
Unlike basic baffles or foam alternatives, GIK’s acoustic ceiling tiles provide real broadband performance. Thanks to the high-density fiberglass core, they absorb sound waves across the frequency spectrum, making them vastly more effective than lower-quality alternatives.
Additionally, our acoustic drop ceiling tiles carry a Class A fire rating, meeting safety requirements for most commercial buildings and public institutions. If you’re replacing Armstrong ceiling tiles, upgrading to GIK’s acoustic solutions give you both peace of mind and sonic improvement.
Drop ceilings are commonly used in large rooms, which are naturally prone to flutter echo, excessive reverb, and noise buildup. By incorporating acoustic treatment into the ceiling grid itself, you address these issues head-on without sacrificing wall space or aesthetics.
Technical Specs
NRC, or Noise Reduction Coefficient, is a standardized way to measure how well a material absorbs sound—specifically in the midrange frequencies most associated with human speech. It’s calculated by averaging absorption performance at four specific frequencies: 250Hz, 500Hz, 1000Hz, and 2000Hz. The result is a single number between 0 and 1, where 0 means no absorption (like a hard surface) and 1 means total absorption (like an open window). An NRC of 0.80, for example, means we’re getting 80% of the maximum possible absorption at those test frequencies for all the sound waves that hit the panel.
But here’s the catch: NRC only tells part of the story. It’s a helpful reference when trying to reduce office noise, control reverberation in public spaces, or make classrooms and conference rooms more intelligible. However, it doesn’t tell you anything about low frequency performance—or how a material behaves at 80Hz, 125Hz, or below—which are critical in recording studios, home theaters, and audiophile listening rooms.
For any serious music or audio environment, you need more than a single NRC number. That’s where full frequency absorption data—like what GIK Acoustics provides in ASTM-certified lab tests—comes in. These detailed charts show exactly how a product performs across the entire audible spectrum, giving you the data needed to make informed decisions about bass traps, acoustic panels, and other acoustic treatment strategies.
The 2″ tiles absorb well down to 300Hz, already a clear upgrade over conventional, thinner ceiling tiles. The 4″ tiles work well into the bass range, down to below 100Hz.
Cost-Effective Performance with Professional Results
Our drop ceiling products are one of the most cost-effective acoustic upgrades available. With installation that takes minutes and a range of design options, they’re a perfect fit for professionals and DIYers alike. Every panel is built-to-order in the USA, typically shipping within 7–10 business days.
These aren’t basic soundproofing tiles or throwaway foam pads—they’re real acoustic panels built with the same high-performance materials as our wall-mounted units. That means you can expect studio-grade results in any space that uses a drop ceiling grid.
