Acoustical Ceiling Tiles
Sound Silencer™ Acoustical Panels
Durable. Cleanable. Beautiful.
Designed for the most challenging and unique acoustic environments, Sound Silencer™ ceiling and wall panels provide high-performance sound control with a clean, modern finish. Made from rigid, porous ARPRO Acoustical Porous Expanded Polypropylene (P.E.P.P.), these lightweight panels deliver both sound absorption (NRC) and sound blocking (STC) — offering an effective, versatile solution for noise reduction across a variety of interior settings.
With a Class A fire rating (ASTM E84) and a non-fibrous, impact-resistant surface, Sound Silencer™ panels are ideal for projects where durability, hygiene, and acoustical performance are critical — including gymnasiums, natatoriums, clean rooms, laboratories, food prep areas, firing ranges, and high-moisture environments.
Key Advantages:
- Dual-performance: NRC and STC rated
- Class A fire rated for code compliance
- Fiberglass-free and non-irritating to indoor air quality
- Water-resistant and easily cleanable
- Tackable and non-abrasive surface
- Suitable for indoor and outdoor installations
- Resistant to moisture, bacteria, fungi, and physical impact
- Lightweight for fast installation and cost-efficient shipping
- Low VOC Emissions- passes CDPH V1.2 Test Standard and con contribute to LEED V4.1 QE Credit: Low Emitting Materials

Note to Installers
Sound Silencer™ is a thermal-molded acoustical sound panel. Although tough to see, one side of the sound suppressor panel will have injection and mold release marks these are circular marks that range in size and indent depth. These marks denote the back side of the cleanable acoustical sound panel so panels should be installed with these marks facing the wall or ceiling for best possible aesthetical outcome.
