Modular Wall Systems vs Drywall Walls: A Comprehensive Comparison
Introduction
When planning interior partitions for commercial and institutional buildings, choosing between modular wall systems and traditional drywall can profoundly impact project timelines, budgets, and long‑term performance. Modular wall systems—factory‑built panels delivered ready to install—offer rapid assembly and consistent quality. By contrast, drywall installations rely on on‑site construction crews, tape‑and‑mud processes, and prolonged drying times. In this article, we conduct an in‑depth, side‑by‑side comparison of modular wall systems and drywall, evaluating key criteria such as fire resistance, moisture performance, service life, aesthetics, and maintenance. We also explain how to select the right modular wall system supplier—highlighting supply capabilities, customization advantages, delivery speed, and service support—so you can make an informed decision for your next project.
What Are Modular Wall Systems?
Modular wall systems consist of prefabricated panels manufactured under controlled factory conditions. These panels can incorporate steel or aluminum framing, acoustic cores, decorative finishes, built‑in electrical and data conduits, and integrated doors or glazing. Once delivered to the site, modular panels click or bolt together along pre-engineered connections, enabling rapid erection of partitions with minimal on‑site cutting or mess. Leading providers like PRANCE Metalwork supply modular wall systems designed for hospitals, offices, airports, and schools—backed by ISO‑certified quality management and CE/ICC certifications.

What Is Traditional Drywall?
Traditional drywall, also known as gypsum board or plasterboard, is built on‑site by fixing 4×8‑foot panels of gypsum core board to wood or steel studs. After hanging, joints must be taped, mudded, and sanded through several coats, followed by primer and paint. While materials are readily available, skilled labor is required to achieve a seamless finish. Project schedules often account for drying times between coats, and on‑site dust and debris can extend cleanup efforts.
Advantages of Modular Wall Systems
Fire Resistance
Modular wall systems often incorporate noncombustible cores and fire‑rated steel frames. Factory‑applied intumescent coatings and UL‑listed firestopping in panel joints help achieve two‑hour fire ratings. This uniformity ensures panels perform identically across batches.
Moisture Resistance
Panels can be manufactured with moisture‑resistant gypsum, cement board, or specialty vinyl facings to withstand humid environments. Sealed factory joints and precision machining eliminate gaps that could allow moisture ingress—critical in healthcare or food‑service settings.
Service Life
Factory assembly under controlled conditions yields tighter tolerances and fewer hidden defects. Combined with corrosion‑resistant framing, modular wall systems typically outlast on‑site drywall partitions, mainly where movement or vibration occurs.
Aesthetics
Modular walls offer a vast palette of finishes—from powder‑coated steel and anodized aluminum to high‑pressure laminates and integrated acoustic fabrics. Precise factory machining yields crisp edges, consistent reveals, and seamless transitions between panels and integrated elements like windows or doors.
Maintenance Difficulty
Should damage occur—such as impact dents or surface wear—individual panels can be removed and replaced without affecting adjacent sections. Removable cover plates also allow easy access to concealed wiring or plumbing for serviceability.
Advantages of Drywall Walls
Familiarity and Availability
Almost every contractor has experience installing drywall, and gypsum board is stocked at local suppliers nationwide. This universal availability can expedite small repair orders or last‑minute material needs.
Lower Up‑Front Material Costs
Gypsum board and studs typically cost less per square foot than engineered modular panels. For minimal partitions under 100 square feet, drywall may remain the more economical choice on paper.
Custom Shapes On‑Site
On‑site cutting and shaping allow installers to adapt panels for irregular openings, curved layouts, or custom built‑in shelving—though these adaptations require skilled labor and extend installation time.
Performance Comparison
Fire Resistance
Modular wall systems frequently achieve higher fire‑rating certifications—up to two hours—due to factory‑applied intumescent coats and precise sealing. Drywall assemblies rely on additional on‑site sealants and tape‑and‑mud applications, which can introduce variability in performance.
Moisture Resistance
While drywall can be installed in bathrooms or kitchens using green or blue board variants, modular panels with cement cores or vinyl facings remain superior in high‑moisture or wash‑down environments. Sealed factory joints further reduce moisture intrusion.
Service Life
In high‑traffic corridors or dynamic spaces, modular systems typically last 15 to 20 years without major overhaul. Drywall may require patching or full replacement in four to eight years, depending on impact and environmental conditions.
Aesthetics
Factory finishes on modular panels maintain color consistency and gloss levels over time. Painted drywall often shows drywall tape lines, nail pops, or uneven texture—especially when subjected to temperature fluctuations and building settlement.
Maintenance
Replacing a modular panel takes hours rather than days. A drywall repair, by contrast, entails cutting out damaged board, re‑taping and mudding seams, and waiting for multiple coats to dry before sanding and repainting.
Cost Comparison
While modular wall systems incur higher material and shipping costs—often 20–35% more per square foot—the labor savings can offset these figures on large projects. Faster installation schedules reduce general conditions costs and allow earlier occupancy. Drywall remains cheaper on small jobs but can become labor‑intensive and time‑consuming for high‑finish requirements.
Installation and Maintenance Considerations
Successful modular wall installations hinge on accurate as‑built dimensions, clear site access, and coordination with other trades for embedded services. PRANCE Metalwork provides comprehensive installation support—from layout drawings and shop drawings to on‑site supervision—to ensure panels fit perfectly and connect seamlessly to ceiling and floor systems.
How to Choose the Right Modular Wall System Supplier
