INCA™ - Sound Diffuser Panel

The INCA™ sound diffuser panel is designed to balance and refine the acoustic response of any interior by evenly dispersing sound reflections. Made from extruded polystyrene (XPS), it is lightweight yet durable, providing superior strength, dimensional stability, and resistance to moisture. Its three-dimensional geometry ensures optimal diffusion across mid and high frequencies, improving clarity without over-absorbing natural room energy.

How It Works

INCA™ panels scatter incoming sound waves in multiple directions, reducing flutter echo and excessive reflections. The varied surface depths break up sound energy to create a diffuse sound field that enhances listening comfort and accuracy. When combined in groups, the diffusers form an abstract visual pattern that is both acoustically effective and aesthetically balanced.

Key Benefits

• Manufactured from dense XPS for strength and long-term durability
• Optimised for mid and high-frequency diffusion
• Lightweight, easy to handle, and simple to install
• Improves spatial clarity and prevents acoustic hot spots
• Modular design allows seamless pattern combinations
• Low-maintenance surface suitable for any interior

Installation Overview

INCA™ panels can be installed directly on walls or ceilings using polyurethane installation adhesive. The 600 × 600 mm format ensures easy alignment and coverage of both small and large surfaces. For optimal diffusion and visual effect, a minimum configuration of four panels is recommended. Installation requires no special tools, making the process fast and precise.
