Cleanroom Fire Wall Construction

Advanced Fire Protection Designed for Sterile Environments

Cleanroom firewall construction delivers dual-purpose performance that standard fire-rated walls simply cannot match: certified life-safety protection against fire, smoke, and heat, combined with uncompromised contamination control in sterile and controlled environments. Every wall assembly must simultaneously resist flame spread for a specified duration and maintain the particle counts, pressure differentials, and surface cleanliness required by cleanroom operations.

At Get a Reno, we engineer fire-rated wall assemblies that protect both people and processes, ensuring your controlled environment stays compliant with fire safety codes and cleanroom classification standards without compromise.

Why You'll Love It

• Contamination Control – Maintains your cleanroom classification during fire events by preserving air integrity, pressure cascades, and particle-free surfaces throughout the wall construction

• Regulatory Compliance – Meets both building code fire safety requirements and ISO 14644 cleanroom standards simultaneously, simplifying inspection and audit processes

• Seamless Integration – Designed to work with your existing HVAC ductwork, HEPA filtration, cable trays, and pressure systems without introducing gaps or contamination pathways

• Minimal Disruption – Get a Reno's construction methods maintain operational cleanroom areas during installation using temporary containment zones and negative air systems

• Long-Term Reliability – Built with chemical-resistant materials that withstand routine sterilization and decontamination processes, delivering durability and performance across years of demanding use

What Makes It Different: Meeting Code Requirements

Most standard fire walls focus exclusively on fire protection-stopping flame and heat for a rated duration. But in a cleanroom environment, a conventional wall assembly can introduce particles, outgassing compounds, or pressure leaks that compromise your entire controlled space. Fire barriers must contain fire hazards without introducing particles or outgassing risks.

Get a Reno's cleanroom fire walls are built differently:

• Specialized Sealants – We use non-particle-generating, FDA-compatible firestop products and sealants that maintain the wall's fire rating while preserving air quality and cleanroom integrity at every penetration point

• Pressure Differential Protection – Cleanrooms often require specific pressure cascades for air integrity and contamination control. Our systems maintain critical pressure relationships between cleanroom zones even under fire conditions, preventing smoke migration and cross-contamination

• Chemical-Resistant Construction – Materials used in cleanroom construction must be compatible with stringent cleaning processes. Get a Reno selects non-shedding, non-porous facings and coatings-stainless steel, PVDF, and baked enamel surfaces-that withstand hydrogen peroxide vapor, peracetic acid, and bleach without degrading fire protection properties

How It Works

1. Environmental Assessment Get a Reno evaluates your existing cleanroom classification (ISO 5 through ISO 8), pressure systems, HVAC ductwork layout, and contamination control requirements. We identify where fire compartments are needed, assess code requirements for your occupancy types, and determine the fire separation rating your building demands. Design adjustments must consider ceiling and plenum areas when integrating fire strategies in cleanrooms, and our assessment covers every transition point. Documenting material flammability test reports is essential for compliance audits, and we begin that documentation process from day one.

2. Specialized Installation Our contractors install fire rated assemblies using cleanroom-compatible methods that maintain environmental controls throughout the project. Panels and components are prefabricated off-site to minimize on-site particle generation. We stage materials in clean zones, use protective film on surfaces, and employ containment barriers so adjacent operational spaces remain unaffected. Firewalls must maintain airtight integrity at floor, ceiling, and wall junctions-and every joint, seam, and penetration receives certified firestopping to preserve both fire rating and cleanroom seal. Specialized fire detection systems are necessary due to the unique airflow in cleanrooms, and Get a Reno coordinates these systems into the overall wall construction.

3. Validation Testing After installation, Get a Reno provides comprehensive verification of both fire rating performance and cleanroom environmental standards compliance. This includes third-party particle count testing per ISO 14644-1, pressure differential measurement, smoke leakage assessment, and chemical emission evaluation under the recently released ISO 14644-15 (2026) standard addressing airborne chemical concentration suitability. You receive full documentation for regulatory inspection and compliance audits.

Construction Details for Fire Rated Wall Assemblies

• Materials: Non-combustible materials are preferred for cleanroom wall construction. Get a Reno uses non-shedding gypsum board (Type X and Type C), steel studs, specialized fire rated sealants, and stainless steel framing components. Cleanroom walls must use non-shedding, non-porous materials that support rigorous sterilization. Core options include rockwool (approximately 150 kg/m³ density for superior fire resistance and insulation), aluminum honeycomb for low-outgassing microelectronics applications, and composite sandwich panels with smooth, sealed facings. Type X drywall contains about 21% chemically bound water, which releases as steam during fire exposure to slow heat transfer. Type C drywall expands when heated for enhanced fire resistance, providing an additional layer of protection in critical assemblies.

• Fire Ratings: Get a Reno offers 1-hour, 2-hour, and 3-hour fire rated wall assemblies for different cleanroom applications. Fire rated walls resist fire for a specific time period, providing time for occupants to escape during a fire and protecting adjacent spaces. A single layer of 5/8-inch Type X drywall achieves a 1-hour rating-the most commonly specified assembly. Adding a second layer of Type X drywall can achieve a 2-hour rating. Two layers of Type X drywall on each side of steel studs achieve a 2-hour rating in standard configurations. Type X drywall typically achieves a 1-hour fire rating, and fire rated drywall is tested as part of a complete assembly to ensure every component performs together. Assemblies must comply with building regulations and achieve a fire separation rating depending on occupancy. Panel thicknesses range from 50 mm to 150 mm depending on core density and the required fire rating.

• Asymmetric Wall Assemblies: For retrofit projects or situations where access is limited to one side, asymmetric wall assemblies provide an efficient solution. Asymmetric wall assemblies have unequal layers of gypsum board and are designed for construction from one side only. They require steel studs for construction. UL design V449 converts a 1-hour wall to a 2-hour wall, making these assemblies ideal for occupancy separations where upgrading existing fire protection is necessary without full demolition.

• Compatibility: Works with ISO 14644 Class 5 through Class 8 cleanroom environments. Regulatory compliance in cleanroom construction includes adhering to standards such as ISO 14644, and Get a Reno ensures every assembly meets your specific classification. Our systems accommodate the stringent requirements of GMP-regulated facilities and commercial manufacturing operations.

• Penetration Sealing: Penetrations like HVAC ducts and electrical conduits require certified firestop systems in cleanrooms. Get a Reno uses specialized firestopping solutions for cable trays, pipes, conduits, and ductwork penetrations. Maintaining the fire barrier integrity is critical for all penetrations in cleanroom walls. Firewalls in cleanrooms require constant sealing around utility penetrations to maintain integrity, and we use firestop pillows and tested sealant systems specifically formulated for cleanroom compatibility.

• Data Centers: Data centers require firestop solutions exceeding local code requirements. European data centers often require multi-hour fire-rated coatings, and structural steel in occupied zones must withstand fire for up to four hours. Get a Reno's expertise in data center design ensures fire rated assemblies meet these elevated standards while protecting critical infrastructure and essential equipment.

• Warranty: Get a Reno provides a 10-year performance guarantee covering both fire protection and cleanroom environmental compliance. Our commitment to code compliance and long-term performance means your investment is protected.
