Product Features
Acoustic Performance
Designed for high sound absorption without visible seams or panels.
Noise Reduction Coefficient (NRC): Usually 0.8–1.0, depending on thickness and installation.
Performs well across mid and high frequencies; can be optimized for low frequencies with added mass or backing layers.
Material Composition
Base Core: Often made from fiberglass or mineral wool, which are non-combustible and inherently Class A-rated.
Surface: Plaster or Resin Finish. Covered with a special acoustic plaster (e.g., gypsum-based or polymer-based) that is typically water-based and can be formulated to be Class A fire-rated when dry. Surface allows sound to pass through to the base core.
Joint treatment: Joints between panels are filled and coated to create a continuous, seamless look.
Fire Resistance & Moisture Resistance
Generally Class A (ASTM E84) or EN 13501 A2-s1,d0 when using mineral-based cores and fire-rated plasters. Moisture-resistant variants suitable for bathrooms, kitchens, and humid environments
Eco-Friendly & Sustainable
Low-VOC, depending on the acoustic plaster used.
Contains recycled content or are LEED-compliant.
Non-toxic and inert when installed
Durability & Strength
Resistant to cracks and warping over time
Made from high-quality materials like gypsum, fiber cement, MDF, or composite materials
Long-lasting with minimal maintenance.
Not ideal for high-touch or dirty environments.
Versatility & Aesthetic Appeal
Available in various finishes (matte, glossy, textured, etc.)
Creates a sleek and modern look

What are seamless acoustic panels, and how are they different?
Seamless panels create a monolithic surface with no visible joints. They are ideal for high-end interiors where design continuity is essential along with excellent acoustic performance.
Can seamless panels be installed on ceilings and curved surfaces?
Yes, the system is highly flexible and can be applied on walls, ceilings, and even curved or angled surfaces.
Are these panels repaintable or repairable?
Yes, the surface can be refinished without losing its acoustic properties, making it a long-term solution for evolving interior aesthetics.
How do they perform acoustically?
Seamless systems typically achieve high NRC values and are excellent for spaces like auditoriums, galleries, and luxury villas.
