Innovating ACT Replacements with Biophilic Layers

Implementing biophilic layers in acoustic ceiling design

Architects and designers are increasingly turning away from traditional ACT (Acoustic Ceiling Tile) systems toward a more dynamic, nature-inspired approach: biophilic layers. Biophilic design integrates elements of the natural world into built environments, creating spaces that promote wellness, creativity, and productivity. When used as an ACT replacement, biophilic layers do more than soften a ceiling visually—they create a living, breathing canvas that improves acoustics, aesthetics, and environmental quality.

Rather than monotonous white grid tiles, biophilic ceiling systems introduce textures, greenery, and soft materials that absorb sound more effectively while providing a vital connection to nature. Especially in large, open spaces, this approach reduces reverberation and fosters a sense of tranquility.

Why are biophilic ACT replacements superior in performance?

Traditional ACT systems were designed primarily for utility: sound control and easy access to mechanical systems. However, their functional advantage often came at the cost of sterile, uninspiring aesthetics. In contrast, biophilic layers offer a trifecta of performance:

Integrating greenery and soft acoustic materials reduces reverberation and promotes a healthier, more inspiring environment. Layers of felt combined with botanical elements naturally enhance noise control by trapping and diffusing sound waves, much more effectively than flat ACT tiles.

Materials and techniques that maximize the potential of biophilic ceiling systems

To achieve optimal acoustic and aesthetic performance, biophilic ceilings can use a combination of materials. Here is the CSI Creative offering:

• Recycled PET acoustic felt for foundational sound absorption.

• Wool designer felt overlays (3mm thick) in over 180+ colors for customizable design.

• Replica or preserved greenery to soften visuals and diffuse soundwaves.

• Integrated mounting systems to seamlessly attach biophilic components into the ceiling grid or suspension system.

These elements are designed to work harmoniously, balancing density, texture, and form to meet specific NRC (Noise Reduction Coefficient) targets while creating an immersive biophilic atmosphere.

How does acoustic greenery work as an ACT replacement?

Acoustic greenery goes beyond mere decoration. Dense foliage components absorb and scatter sound, functioning similarly to traditional acoustic treatments but with added biophilic benefits. Depending on the lushness and layering, greenery can contribute significantly to sound attenuation.

Here’s how the physics work:

• Absorption: Leaves and tendrils trap sound waves, preventing echo and noise buildup.

• Diffusion: Irregular shapes and surfaces break up sound energy, redistributing it evenly.

• Reflection Control: Soft, organic surfaces minimize hard sound reflections common in standard ACT ceilings.

By incorporating greenery into ceilings, designers achieve acoustical control while simultaneously enhancing indoor air quality (especially with living plants) and biophilic connections.

What are inspiring real-world applications of biophilic ACT replacements?

Open Workspaces: In open offices, suspended greenery baffles or cloud systems can define zones without building walls. They improve focus and dampen disruptive noises.

Hospitality Spaces: Hotels and restaurants can create lush overhead canopies to offer guests a soothing, high-end experience, promoting longer stays and greater comfort.

Educational Facilities: Biophilic ceilings in libraries or collaborative learning zones reduce noise levels, enhancing concentration and engagement among students.

Healthcare Settings: Clinics and hospitals benefit from reduced stress levels among patients and staff by introducing calming natural visuals combined with sound dampening.

Retail and Commercial Centers: Large atriums can be transformed with hanging gardens that function as acoustic solutions and visual centerpieces, encouraging shoppers to linger.

How does CSI Creative’s biophilic innovation set new benchmarks?

While many firms attempt biophilic designs, CSI Creative has innovated beyond by offering fully integrated Acoustic Greenery systems, designed for Division 09 specification. These systems combine the acoustic strength of Soundcore® PET Felt and the luxurious texture of PoshFelt® Wool Designer Felt with the organic presence of biophilic elements.

With products like Earth Acoustic Greenery and custom biophilic ceilings, CSI ensures:

• Fire-rated ThermaLeaf® greenery (ASTM E84 Class A).

• Seamless pre-assembled systems (no complicated onsite builds).

• Endless customization in greenery type (live, preserved, replica).

• High NRC values improving conversational clarity.

Our work with clients like Fatpour Tap Works shows how branded acoustic greenery ceilings aren’t just practical—they’re emotional, atmospheric, and memorable.

Discover the CSI Creative offering that transforms ceilings from forgotten utilities into living, breathing experiences. Our acoustic greenery and biophilic ceiling systems not only meet the highest architectural standards but create human-centric environments built for connection, calm, and creativity.
