Green walls—often called vertical gardens—are considered a signature of modern biophilic design. These systems introduce greenery into commercial interiors through live, preserved, or artificial plants integrated into modular wall systems. But beyond aesthetics, they are functional acoustic systems designed to absorb sound, reduce stress, and support sustainability goals.
Green walls balance visual warmth, acoustic performance, and ease of integration into a wide range of commercial environments. Whether trimmed, lush, or mixed in density, every green wall project begins with a comprehensive approach to materials, system design, and architectural adaptability.
Step 1: It All Starts With Design Intent
Every green wall begins with a spatial concept. Architects and designers identify the function—be it biophilic enhancement, acoustic control, or branding—and the location within the building. This is where the project’s goals take shape: Should the wall feel wild and immersive or controlled and sculptural? Will it span a lobby, define a collaborative workspace, or enhance a corridor’s acoustics?
From the start, design intent influences the density and type of greenery, the need for acoustic performance, and whether the system will incorporate live plants, preserved moss, or replica foliage. These early decisions guide the material palette and inform how the structure will interact with the architecture around it.

Step 2: Material Selection and Acoustic Planning
With the design intent defined, the selection of materials comes next. For acoustic green walls, a performance backer—typically recycled PET felt or a high-density wool felt—is chosen to provide structural integrity and sound absorption. These substrates serve as both canvas and core, forming the system’s base layer.
The choice of greenery is equally critical. Replica plants, often favored for low maintenance and fire safety, are molded with integrated flame-retardant compounds. Preserved moss offers a natural texture while staying virtually maintenance-free. Live plants are reserved for environments where irrigation, lighting, and climate can be controlled.
Together, these layers create a visual and acoustic experience tailored to the space. The felt absorbs and diffuses sound; the foliage interrupts and softens it.
Step 3: Built-In Fire Resistance
A key part of the process—often invisible to the end user—is ensuring all materials meet rigorous fire codes. Artificial greenery used in high-traffic interiors must comply with Class A fire ratings such as ASTM E84, NFPA 701, and other global certifications. This is commonly achieved by post-treatment sprays, but in CSI Creative, we achieve it through proprietary thermoplastics molded into the foliage itself. Similarly, PET felt and wool substrates are tested and certified to maintain Class A fire retardancy.
At this stage, each component is prequalified for safety, allowing the design to move confidently toward fabrication without compromise.

Step 4: Technical Drawings and Site Integration
Before production begins, detailed shop drawings are created. These architectural documents map the green wall into the building with precision—accounting for exact dimensions, mounting conditions, penetrations, and any MEP conflicts.
Unlike modular kit-based products, green walls at this level are engineered specifically to the site. Whether following a curved atrium wall or nesting within a recessed panel, the drawings ensure that every inch of the installation will align perfectly with the built environment.
This is the bridge between design and manufacturing—the phase where architectural vision becomes a buildable solution.
Step 5: Fabrication of Acoustic Backers
Once the drawings are approved, fabrication begins with the backer. Panels are CNC-cut from acoustic felt to match the dimensions and shapes required. This includes adjustments for cutouts, layering, curvature, or branding features like inset logos or dimensional lettering.
If wool felt overlays are part of the aesthetic, they are laminated or stitched onto the PET base, creating a layered surface that softens sound and enhances tactility. These backers are the architectural skeleton of the green wall.

Step 6: Greenery Assembly
With the backer panels prepped, the greenery is installed in-shop. Depending on the desired density—trimmed, lush, or mixed—the foliage is arranged and secured by hand to ensure consistency and quality control.
Rather than assembling on-site, greenery is applied during production. This ensures every panel meets the visual standard established in the design and reduces labor and variability during installation. Foliage is arranged to follow the contours of the design, leaving space for lighting or signage if required.
Step 7: Quality Control and Fire Certification
Each panel undergoes thorough quality inspection for build integrity, greenery attachment, and alignment with design intent. For regulated environments, fire test labels and compliance documents are applied to the final product.
If a mockup or approval sample was required, it’s compared directly to the full production run to ensure consistency before packaging.

Step 8: Packaging and Delivery
Panels are packed with extreme care to protect foliage depth and shape. Spacers, padded wraps, and zone labels help ensure that panels arrive exactly as intended. Each shipment includes a detailed install plan with labeled components and mounting systems.
Because the panels are pre-assembled, there’s no need for site-built arrangements, trimming, or foliage handling, reducing mess and install time significantly.
Step 9: Installation on Site
Installation teams receive plug-and-play systems. Each panel is numbered and corresponds to the wall layout map, allowing it to be mounted directly to the wall or framework using cleats, clips, or pre-drilled hardware.
Since the systems are engineered to match the site, installation is efficient and straightforward. No secondary assembly or on-site adjustments are typically needed—especially in high-profile zones like atriums or conference center lobbies where install speed matters.

Step 10: Customization and Future Adaptability
After install, the system remains adaptable. Many designs include space for seasonal updates or modular expansion. Green walls can be refreshed with different foliage types, new signage, or additional panels.
Architects designing for long-term use often build in flexibility—for branding, tenant transitions, or acoustic adjustments over time. These systems can evolve as the space changes, making them not only beautiful and functional, but also future-proof.
Final Thoughts
Making a green wall is more than attaching leaves to a surface. It’s a disciplined architectural process that blends material technology, fire engineering, acoustic science, and fabrication precision. By understanding each step—from concept through installation—designers can better leverage green walls not just for aesthetics, but for how they shape space, experience, and sound.
