Certified Cleanroom Build and Construction Services | ISO 14644 Compliant
Precision-Engineered Cleanroom Construction
Following a successful design qualification, the construction phase must translate precise blueprints into a fully operational, airtight environment. At ISO Cleanroom, we manage the complete physical installation of your controlled facility, delivering a high-performance build that satisfies stringent regulatory handovers.
Our construction teams handle everything from structural envelope assembly to complex mechanical integration. By controlling the build lifecycle from ground-breaking to pre-validation testing, we ensure your clean zone achieves total structural integrity and absolute particulate containment.
Technical Build Management
Constructing a controlled environment requires specialist installation protocols to eliminate structural vulnerabilities. Our build methodology focuses on four primary execution variables:
- Airtight Envelope Integrity: We construct cleanrooms using premium modular panelling systems with tongue-and-groove interlocking joints, pressure-sealed with high-specification silicone to eliminate air leakage.
- Flush Interior Architecture: Every wall-to-wall, wall-to-ceiling, and wall-to-floor junction is fitted with radius coving, ensuring all transitions are entirely flush to facilitate rapid, effective sanitisation.
- Mechanical Plant Integration: Our construction teams work concurrently with specialist HVAC technicians to position Air Handling Units, ductwork distribution lines, and fan filter units without compromising structural seals.
- Contamination-Controlled Construction: We enforce strict multi-stage cleaning protocols during the physical assembly process, preventing construction dust and particulates from becoming trapped within wall cavities.
The Build Process: From Manufacturing to Installation
Once the design phase is complete, we move into the physical build. Our process is structured to minimise site disruption and ensure the highest levels of quality control.
1. Controlled Manufacturing
Pre-site phase
All components, including wall panels and ceiling grids, are manufactured to the precise dimensions of your project brief to reduce on-site dust.
2. Specialist Installation
On-site assembly
Our teams are trained in cleanroom-specific assembly. We coordinate the integration of utilities, HVAC systems, and Cleanroom System Build components to ensure the envelope is airtight.
3. Cleanroom Upgrades and Modifications
Post build adaptability
If you have an existing facility, we also specialise in Cleanroom Upgrades. We can retro-fit new filtration or update wall systems to increase your ISO classification.
Deploying in High-Risk Infrastructure
The physical assembly of a controlled environment often demands flawless execution within complex, active transportation, financial, and energy infrastructure. As an ISO 9001 certified provider and a CHAS accredited Principal Contractor, our construction teams possess the specialist training, rigorous safety standards, and technical skills required to install high-performance clean envelopes under extreme physical constraints, ensuring total structural integrity where traditional building methods are impossible.
Partnering with Balfour Beatty, our turnkey installation capabilities included constructing specialised cleanrooms directly onto operational rolling stock positioned deep within the Channel Tunnel. Built to safeguard the critical electrical infrastructure connecting power grids between France and the UK, whilst maintaining the continuous data networks required by global banking institutions, these modular units required strict vibration-isolated panelling, flame-retardant structural seals, and ultra-compact HVAC integration to guarantee absolute particulate isolation within a high-voltage, high-vibration subterranean transit environment.
Why Partner with ISO Cleanroom for Your Build?
Our Construction-to-Handover Package Includes:
- Pre-Validation Testing: We perform rigorous structural pressure testing and smoke profiling before formal validation teams arrive, ensuring an immediate pass rate.
- Operational Cleanliness: Our site teams operate under strict zone controls, stepping up clean protocols as the room nears physical completion.
- Complete Material Traceability: Every panel, flooring compound, and light fitting comes with full material data sheets to populate your final validation file.
Cleanroom Fabric and Fit-Out Components
We select and install specialised architectural components tailored specifically to the structural demands of classified clean environments:
| Build Component | Standard Specification | Operational Performance Benefit |
| Wall & Ceiling Panels | Unplasticised Polyvinyl Chloride (uPVC) coated steel / Aluminium honeycomb | Non-shedding, impact-resistant, and entirely resilient to harsh chemical biocides. |
| Cleanroom Flooring | Seamless vinyl / Self-levelling epoxy resin | Heavy-load capable, entirely non-porous, with coved skirtings to prevent fluid ingress. |
| Vision Panels | Double-glazed flush safety glass | Completely flush with the wall profile to prevent dust accumulation while maintaining visibility. |
| Access Systems | Electronic interlocking doors (PAL/MAL) | Prevents simultaneous door openings, preserving pressure cascade stability between zones. |
Structural Assembly by Sector
We configure the physical shell of your cleanroom to match the precise environmental risks of your specific industry sector:
Pharmaceutical & Biotech
We install heavy-duty, biocide-resistant modular systems designed to withstand daily chemical washdowns. All service penetrations are hermetically sealed, and we integrate automated material airlocks (MALs) and personnel airlocks (PALs) to manage pressure boundaries.
Medical Devices & Advanced Engineering
Our teams install high-grade static-dissipative (ESD) flooring alongside modular wall systems, creating ergonomic manufacturing and packaging layouts that prevent static buildup from attracting fine particulates.
Semiconductors & Electronics
For ultra-clean zones requiring high air-change rates, we construct structural steel mezzanine platforms to support heavy ceiling grids, fan filter units (FFUs), and tear-drop lighting profiles designed to maintain unidirectional airflow.
Integrated Turnkey Engineering
Your cleanroom build operates in complete harmony with our wider lifecycle services, ensuring a smooth path from shell assembly to final handover:
- Cleanroom Design: Transforming your initial operational space into fully compliant structural blueprints.
- Cleanroom Validation: Rigorous validation testing to guarantee your built facility satisfies IQ/OQ/PQ requirements.
- Cleanroom Maintenance: Planned preventative service contracts to protect your HVAC infrastructure, structural seals, and HEPA filters.
FAQs
Modular cleanroom construction uses pre-engineered, factory-finished wall panels and ceiling tracks that assemble rapidly on-site with zero dust generation, whereas traditional building methods rely on plasterboard and wet trades that introduce high particulate risks. Modular builds allow for future modifications, cleanroom upgrades, or cleanroom rental setups without destroying the core facility structure.
Structural airtightness is verified by conducting a pressure decay test, where the completed cleanroom envelope is pressurised to a specific benchmark (typically 20 to 50 Pascals) and monitored for air leakage rates over a set period. Our construction teams run these pressure tests before installing internal equipment to catch and seal any microscopic structural leaks early.
Yes, cleanroom construction can take place within an active facility by erecting physical dust barriers, isolating HVAC zones, and establishing strict material delivery routes to keep your day-to-day operations completely segregated from the build site.
Seamless vinyl flooring is preferred because the joints are chemically welded to form a continuous, impervious surface that eliminates cracks where microbes or particulates can settle. This flooring is turned up the wall using a radius cove anchor to ensure there are no sharp 90-degree corners at floor level.
Airlocks serve as physical pressure buffers that isolate the inner clean cores from outer unclassified corridors during active operation. During construction, we build these spaces with electronic interlocks to ensure that pressure boundaries remain perfectly stable when personnel or materials enter the suite.
Build Engineering Compliance
Every cleanroom facility installation is reviewed and approved under the direction of Toni Horsfield, Managing Director at ISO Cleanroom. Our construction workflows, material selections, and airtightness standards are guaranteed to align fully with current ISO 14644-1:2015 standard protocols and the latest EU GMP Annex 1 structural updates.
