Angular Relief Facets · Synchronized Sound Diffusion & Absorption (NRC 0.85) · 100% Recyclable Polyester Fiber
A modular geometric acoustic wall system manufactured from thermoformed, high-density PET felt. By pairing sharp triangular facets with hollow rear sound-trapping chambers, these panels diffuse specular room flutter and absorb speech reverberation without relying on chemical adhesives, formaldehyde, or heavy secondary framing.

Sculptural Triangular Relief
Thermoformed triangular facets create continuous dynamic shadow lines and architectural depth, turning standard flat gypsum into an acoustic focal wall.
Diffusion + Cavity Absorption
Multi-angled surface facets scatter high-frequency slap reflections, while the hollow rear chamber absorbs speech reverberation (NRC 0.80–0.90).
Zero Glues & Formaldehyde
100% PET fibers thermal-bonded under high pressure without chemical adhesives. Odorless, non-allergenic, and compliant with French VOC A+ standards.
Commercial Fire Classification
Certified ASTM E84 Class A (US Commercial Standard) and EN 13501-1 Class B-s1, d0 fire ratings for educational, commercial, and hospitality spaces.

Our modular thermoformed models feature triangular pyramids, diamond facets, organic waves, and geometric tessellations that interlock seamlessly for modular acoustic murals.

Certified ISO 354 and ASTM C423 laboratory measurements confirm balanced absorption across vocal and mechanical noise octaves (125Hz to 4000Hz), significantly lowering reverberation time (RT60) in commercial interiors.

From modern corporate neutrals (Charcoal, Silver Gray, Off-White) to bold brand accent tones. Colors can be combined within single orders to create dynamic gradient murals. Physical swatch boxes are dispatched within 48 hours.

Engineered for corporate headquarters, hotel lobbies, auditorium feature walls, executive boardrooms, and creative media screening spaces.
