The acoustic panels are installed, the project is complete, and the client is unhappy. What went wrong?
This scenario frustrates design teams more often than it should. Standard acoustic products carry documented NRC ratings and established performance data. Yet post-occupancy complaints about echo, noise, and speech clarity persist. The disconnect typically isn’t product failure. It’s a specification mismatch.
Custom wood panels address acoustic challenges that catalog products cannot. They allow targeting specific frequency ranges, accommodating complex geometries, and maximizing effective coverage despite mechanical, electrical, and plumbing coordination constraints. Understanding when and how to specify custom solutions transforms acoustic outcomes from hopeful to reliable.
Why Standard Acoustic Approaches Sometimes Fail
Specifying acoustic products based solely on published NRC ratings overlooks critical variables. Lab-tested performance reflects idealized conditions that rarely match real installations.
The Gap Between Lab Ratings and Installed Performance
NRC ratings measure sound absorption in controlled environments with standardized mounting configurations. Actual installations introduce variables that laboratory conditions exclude. Panel edges, seams, and penetrations create gaps where sound waves pass unabsorbed. Mounting heights differ from test configurations. Room boundaries interact with panels in ways that flat surfaces cannot replicate.
Industry benchmarks indicate that high-traffic spaces require NRC 0.80+ and CAC 35+ for optimal performance. Achieving these targets depends on installed performance, not product specifications alone.
How Room Geometry Affects Acoustic Outcomes
Sound behaves differently in every space. Parallel walls create a flutter echo. High ceilings increase reverberation time. Curved surfaces focus sound unexpectedly. Open-plan layouts allow noise to travel across zones without interruption.
Standard panel specifications assume rectangular rooms with predictable sound paths. When geometry departs from these assumptions, acoustic performance suffers. The panels aren’t defective. The specification didn’t account for how sound actually moves through the space.
Mechanical, electrical, and plumbing penetrations compound these challenges. Sprinklers, diffusers, lighting fixtures, and access panels fragment ceiling coverage. Each penetration reduces the effective absorption surface area. In coordination-intensive ceilings, actual coverage may fall 20-30% below nominal panel area.

When Custom Wood Panels Become Necessary
Not every acoustic challenge requires a custom specification. Standard products perform excellently when properly matched to straightforward applications. Custom solutions become necessary when project conditions exceed catalog capabilities.
Recognizing Custom Specification Triggers
Complex geometries represent the clearest trigger. Curved walls, sloped ceilings, and irregular floorplates create acoustic conditions that flat panels cannot adequately address. Custom configurations like Curvatone curved acoustic panels combine performance with shaping that follows architectural intent.
Unusual noise sources also trigger custom needs. Mechanical equipment generates low-frequency sound that standard perforations may not absorb effectively. Speech privacy requirements demand specific frequency targeting that generic panels cannot provide. Custom perforation patterns and backing configurations allow tuning absorption to actual noise profiles.
Coordination-intensive ceilings benefit from custom panel sizing. When standard dimensions leave gaps around penetrations, sound passes through unabsorbed. Custom sizes maximize coverage within project constraints.
When Standard Products Still Work
The standard specification remains appropriate when the room geometry is predictable, system coordination is manageable, and performance requirements fall within the catalog capabilities. For these projects, the Select N’ Ship quick-ship program provides accelerated delivery of proven configurations.
The decision isn’t about premium versus economy. It’s about matching the solution’s complexity to the challenge’s complexity.

The Custom Specification Process
Custom wood panels require manufacturer collaboration from schematic design through installation. This partnership prevents the mismatches that cause standard specifications to underperform.
What to Bring to a Manufacturer Consultation
Effective consultations begin with complete information. Provide room dimensions and geometry, including ceiling heights, wall angles, and any curved or irregular surfaces. Document noise sources: mechanical equipment locations, adjacent uses, and primary acoustic concerns. Define performance targets: required NRC and CAC values, speech privacy needs, and any certification requirements.
Coordination drawings help manufacturers understand penetration constraints. Budget parameters and timeline expectations shape fabrication planning. The more context provided upfront, the more precisely manufacturers can configure solutions.
From Consultation to Fabrication
Manufacturer technical teams analyze the provided information and recommend configurations. This typically includes perforation patterns targeting identified frequency ranges, backing materials optimized for the required absorption, and panel sizes that maximize coverage within coordination constraints.
Shop drawings translate recommendations into fabrication specifications. These drawings show exact panel dimensions, perforation locations, and coordination with other ceiling elements. Review cycles confirm alignment with design intent before production begins.
Custom fabrication adheres to the Architectural Woodwork Institute’s quality standards, ensuring consistency across all panels. Throughout this process, Rulon maintains sustainability credentials, including FSC certification for all custom fabrication.
The specification process for wood ceiling systems extends beyond acoustics to include fire ratings, sustainability verification, and installation coordination.
Common Acoustic Challenges and Custom Solutions
Specific challenges require specific solutions, and custom wood panels address problems that standard products cannot solve. The following scenarios illustrate how custom wood panels address problems that standard products cannot solve.
High-Volume Spaces
Large atriums, auditoriums, and lobbies generate excessive reverberation when ceiling panels alone provide insufficient absorption. When flat ceiling coverage reaches practical limits, wood baffles add vertical absorption surfaces that intercept sound waves traveling horizontally across spaces.
At the Milken Institute for Public Health, George Washington University, Rulon manufactured 25,000 square feet of acoustic and decorative panels with unique curved profiles. Wood was selected over metal or synthetic alternatives for its superior acoustic performance and tactile warmth in large-volume spaces where standard panels would have proven inadequate.
Open Office Acoustics
Open-plan layouts demand acoustic strategies balancing absorption with appropriate speech communication. Zoned ceiling treatments provide higher absorption in focus areas while maintaining connectivity in collaborative zones. Custom panel configurations allow varying NRC performance across a single ceiling plane.
Linear wood ceiling systems offer modular flexibility for spaces requiring both acoustic performance and easy coordination with building systems.
Complex Geometries
Curved ceilings, sculptural forms, and irregular geometries make standard panel installation difficult. Curvatone panels combine acoustic performance with custom shaping, allowing ceiling treatments to follow architectural intent rather than forcing rectangular modules onto curved surfaces.
At the Judy Genshaft Honors College, Rulon’s Grille and Aluratone panels manage reverberation in collaborative areas with complex spatial programming, demonstrating how custom configurations address challenges standard products cannot.
Coordination Challenges
Ceiling systems dense with lighting, sprinklers, and diffusers fragment acoustic coverage. Custom panel sizes minimize gaps between penetrations. Custom layouts coordinate panel seams with system locations rather than forcing penetrations through panel centers.
Beyond solving immediate acoustic challenges, custom wood panels contribute to indoor environment improvements, including wellness and productivity gains that the International WELL Building Institute recognizes as core contributors to occupant health.

Working with Manufacturers on Custom Specifications
Manufacturer partnership extends beyond product supply. Technical consultation, shop drawing development, and installation support prevent the specification failures that frustrate design teams.
The Value of Manufacturer Partnership
Early engagement during schematic design allows acoustic requirements to influence ceiling layout decisions rather than forcing solutions into predetermined configurations. Manufacturers identify potential challenges before they become field problems. They recommend configurations matching actual project conditions rather than generic specifications.
Pre-installation meetings align contractor teams with manufacturer expectations. Rulon provides detailed shop drawings, mounting diagrams, and on-site guidance when needed. Field verification confirms installed performance meets design intent.
From Specification to Installation
Custom specification doesn’t end when panels ship. Ongoing support ensures fabricated products are installed correctly and perform as specified. Project documentation demonstrates compliance with acoustic, sustainability, and quality requirements.

Frequently Asked Questions
How do I know if my project needs custom wood panels versus standard products?
Consider custom specification when room geometry includes curves or irregular shapes, when noise sources require specific frequency targeting, when ceiling penetrations exceed 15-20% of total area, or when performance requirements exceed standard catalog capabilities. Standard products work well for rectangular rooms with manageable coordination and typical NRC requirements. When in doubt, manufacturer consultation helps determine the appropriate approach without commitment.
What information should I provide when requesting a custom acoustic consultation?
Bring room dimensions and geometry including ceiling heights, wall angles, and any irregular surfaces. Document noise sources and their locations, noting whether they’re mechanical, speech-related, or external. Define performance targets including required NRC and CAC values along with any certification requirements. Share coordination drawings showing penetration locations for lighting, sprinklers, and diffusers. Communicate budget parameters and timeline expectations. The more complete the information, the more precisely manufacturers can configure solutions. Photographs of existing conditions help considerably for retrofit projects.
How long does custom wood panel fabrication typically take?
Custom configurations typically require 10-14 weeks from order to delivery. This timeline includes shop drawing development, sample review and approval, fabrication, and finishing. Standard catalog products with common finishes ship faster, often within 6-8 weeks. Early manufacturer engagement during schematic design provides adequate lead time without compressing production schedules. Large projects may require staged deliveries coordinated with construction sequencing. Rush schedules are sometimes possible but may incur premium charges and limit sample review cycles. Discussing timeline requirements early helps identify potential constraints before they become problems.
Can custom wood panels achieve the same sustainability certifications as standard products?
Yes. Rulon maintains FSC certification across all custom fabrication, ensuring a verifiable chain of custody regardless of panel configuration. Third-party verified Environmental Product Declarations and Health Product Declarations document environmental impact for custom specifications. Low-VOC, CARB Phase 2 compliant finishes apply to custom products just as they do to standard configurations. Custom specification doesn’t compromise sustainability credentials, and documentation supports LEED and WELL certification for custom installations.
What if my acoustic panels are already installed but underperforming?
Retrofit options exist for underperforming installations. Additional panels or supplementary baffles can increase absorption surface area without removing existing materials. Panel reconfiguration may improve coverage efficiency by addressing gaps around penetrations. In some cases, replacing the backing material enhances the performance of the existing panel in specific frequency ranges. Manufacturer consultation for remediation begins with assessing current conditions, measuring actual acoustic performance, and identifying specific gaps between design intent and installed outcomes. Contact Rulon’s technical team to discuss retrofit strategies for existing installations.
