Architect’s Guide to Choose a Green Wall Manufacturer

Selecting a green wall manufacturer involves far more than finding someone who can assemble plants on a surface. For architects, it is about verifying the technical integrity behind the system—its materials, certifications, fire resistance, acoustic properties, and adaptability to your project’s spatial conditions.

A credible manufacturer provides full transparency: every material—both the backer structure and the foliage—must be listed, copyrighted (not merely trademarked), and compliant with relevant ASTM, NFPA, or EN standards. Their documentation should include fire-retardant test results such as ASTM E84 Class A ratings, as well as details on color ranges, thicknesses, NRC (Noise Reduction Coefficient) values, and customization options. These are not optional—they are the foundation for both compliance and design precision.

What to Look for in Material Specifications

For indoor green wall systems, the backer material should ideally be acoustically absorbent and sustainable—such as PET felt or composite panels with proven NRC ratings (typically 0.70 +). The foliage can be preserved, live, or high-quality replica greenery. Replica or preserved systems, especially those treated with ThermaLeaf® or similar proprietary fire-retardant technologies, ensure long-term safety without continuous maintenance.

For outdoor installations, backers must withstand weather and UV exposure, often using aluminum composite or sealed architectural-grade PET. Live foliage requires integration with irrigation and drainage systems, which the manufacturer should engineer as part of their system—not delegate to third parties.

Below is a simplified material checklist:

Why Fire Ratings and Certifications Matter

All green wall systems must demonstrate compliance with ASTM E84 Class A, NFPA 701, or equivalent standards. Without these, the system risks rejection during building inspection. The manufacturer should provide detailed certificates of compliance, not just marketing claims. Additionally, products designed for commercial interiors should comply with WELL Building and Declare transparency standards, ensuring low VOC emissions and responsible sourcing.

Fire-retardant foliage, particularly for indoor spaces, must have fire resistance built into the polymer during manufacturing—not added via spray coatings that deteriorate over time. This distinction directly impacts project liability and long-term safety.

Acoustic and Performance Considerations

An authentic green wall manufacturer integrates acoustic performance testing into their product development. Look for systems with documented NRC values, ideally verified through independent labs. When greenery integrates with felt or PET panels, the design can significantly improve reverberation control and speech clarity in open-plan offices, lobbies, and hospitality spaces.

Top-tier manufacturers also provide on-site or virtual space acoustic analysis, offering data-driven insight into where and how their systems perform best. This ensures the final installation supports not just aesthetic goals but also functional sound control.

The Importance of True Manufacturing Capabilities

Distinguish between manufacturers and assemblers or resellers. Many suppliers only purchase third-party foliage and mount it on panels—they do not design or test the full system. A true green wall manufacturer fabricates in-house, conducts fire and acoustic tests on the complete assembly, and maintains U.S.-wide service coverage.

They should provide:

• Custom shop drawings and 3D models prior to production.

• Direct installation (preferred) services or certified installers.

• Nationwide logistics ensuring consistent quality control.

• Single-point project management, avoiding fragmented communication with third-party reps.

Architects should request documentation verifying the company’s manufacturing location, testing data, and installation portfolio to confirm these claims.

Customization and Aesthetic Freedom

Every architectural space demands a unique approach. The best manufacturers allow full customization in:

• Foliage density (trimmed, lush, or mixed).

• Color and plant species combinations.

• Panel size, curvature, and attachment system.

• Integrated lighting or branding features.

These elements turn a green wall from decorative to architectural—an extension of the project’s concept and material palette. For designers, flexibility in finish and geometry directly impacts creative expression.

Choosing a Partner That Understands Architecture

Beyond manufacturing competence, look for a partner fluent in architectural language—one who can collaborate on specifications, coordinate Division 09 documentation, and assist during design development. Their team should include dedicated design and acoustics specialists, ensuring that biophilic aesthetics, performance, and code compliance coexist in harmony.
