Data Center Containment Systems for Construction and Renovation

Data center construction runs into serious money, and the equipment racked inside costs even more. So when you’re building or renovating around live systems, the job comes down to one thing: protecting what’s running while crews keep moving.

Data center containment systems keep that work sealed off from live equipment. They keep airflow predictable and reduce dust exposure for live systems. When teams use them well, they reduce risk without slowing the job down.

We’ll go over exactly what data center containment solutions are, why they’re important, how they work, and where they work best.

What Are Data Center Containment Systems?

Data center containment systems are physical barriers that control how air moves through a facility. Their main job is to keep cold supply air separate from hot exhaust air so cooling stays efficient.

Most systems do that by enclosing the hot aisle or cold aisle with doors, ceiling panels, walls, or partitions. Containment cuts down on air mixing so temperatures stay steadier along the row.

In construction, the role expands. Containment walls also separate active equipment from nearby work. Instead of letting dust and airflow disruptions spread through the room, teams create zones they can manage.

How Data Center Containment Systems Work

Containment systems create boundaries that shape airflow and separate work areas. In daily operations, that usually means hot aisle containment or cold aisle containment.

Hot aisle containment encloses exhaust air and sends it back to cooling returns. Cold aisle containment encloses supply air, so server intakes get colder, more consistent air.

During construction, those same principles support cleaner project zones. A modular wall or enclosed partition can separate live racks from dust-producing work. That keeps the construction area contained while the rest of the room stays stable.

Hot Aisle and Cold Aisle Strategies

The best setup changes from one facility to the next. Layout, cooling design, rack density, and existing infrastructure all shape the decision.

Cold aisle containment is the classic raised-floor approach, and it's usually the simpler, cheaper retrofit.

You're capping the aisle the racks already face, which is why it often pays back in weeks. A fully sealed cold aisle can handle high density when there's enough supply airflow, but its comfort zone is the low-to-moderate range most existing halls were built around.

Hot aisle containment captures exhaust and routes it back through a ceiling plenum or ducted return, so it needs more overhead infrastructure. That's why it's usually easier to design into a new build than to retrofit into an existing room.

Both approaches reach the same high densities once fully sealed. Its real edge is resilience: because the whole room stays cool, every rack intake draws on a large reservoir of cold air if the cooling plant ever hiccups.

Either way, the win is the same: stop hot and cold air from mixing so the cooling plant isn't fighting itself. On a live construction project, the practical tiebreaker is usually which layout you can seal cleanly and still move carts and crews through.

How Containment Protects Uptime During Construction and Renovation

Construction dust is a nuisance in most buildings. In a data center, it can become an operational problem.

Cutting, drilling, sanding, and demolition release fine particles that can move into cabinets and cooling paths. Once that happens, cooling has to work harder, and maintenance demands begin to climb.

Airflow is the second risk. A data center only stays cool when its air moves exactly where the design intends, and construction can throw that off quickly. Changing room boundaries or putting up weak temporary barriers creates hot spots and wastes cooling capacity.

Data center protection during construction comes down to this: containment keeps that airflow intact by stopping supply and exhaust air from mixing, even as the room around it changes.

Cooling can account for up to 40% of a data center’s energy use, according to the U.S. Department of Energy. Since so much energy goes into keeping temperatures in check, containment has to be part of the planning from the start.

How Modular Containment Outperforms Drywall and Plastic

Inside a live data center, a temporary wall has a harder job than steering air. It has to keep demolition dust off gear that never powers down, and hold the work zone apart from racks that are still running. Not every barrier can do both.

Teams really choose between three: plastic sheeting, drywall, and modular containment. And they don't perform anywhere close to the same.

Plastic sheeting goes up quickly, but it tears easily and rarely seals well enough for a sensitive environment. It marks off space, yet it doesn’t give much control over airflow.

Drywall creates a more solid barrier, but crews generate dust when they install and demolish it. They spend more time on labor and cleanup and throw away the material when the project ends. In a live data center, using drywall often creates the same mess the barrier aims to stop.

Modular data center containment solutions give teams a stronger mix of speed and performance. Crews install panels faster than drywall, and the systems seal more effectively than poly.

Teams reuse panels on future phases instead of sending them to a dumpster, and the walls look finished enough for occupied or customer-facing spaces. That finished look is why STARC pushes teams past poly and drywall toward dedicated containment.

What to Look for in a Construction-Ready System

Some systems focus mainly on airflow. That helps during normal operation but doesn’t fully address construction risk. In a live data center, the system also needs to support access, tight seals, and flexible layouts.

A construction-ready containment system should:

• Support fast installation and removal

• Include doors where crews actually pass through

• Use panel layouts that adjust to field conditions

• Seal tightly enough to limit air and dust leaks

• Integrate negative air or filtration when dust levels are high

Well-designed containment also improves cooling performance and can cut energy use, since it puts conditioned air where it’s needed. Those gains depend on choosing a system that fits both the room and the project.

How STARC Contains a Live Data Hall

STARC builds modular containment wall systems for teams working inside live data centers, and its LiteBarrier™ system is purpose-built for the job. It's light enough to relocate as the work moves through the hall, and it seals tight enough to keep a live room clean while crews cut into the space next door.

Telescoping panels adjust from slab to ceiling, so the enclosure closes off at the top instead of stopping short. Gasketed edges and door sweeps seal it at the floor and ceiling, and wide doors let loaded carts and equipment through without anyone propping a panel open.

Two installers can stand up about 100 linear feet in an hour, so containment is in place before the heavy work starts.

On a live project, that tight seal keeps dust and leaked air out of operating racks, so conditions stay stable while work happens right next to them. And because the wall goes up fast, tenants and facility staff feel far less disruption than a drywall build would cause.

Containment in New Builds vs. Live Renovations

The job changes depending on whether you're building the hall or working inside one that's already running.

In new construction, containment earns its place the moment the first pod goes live. Phased rollouts bring one room online while crews finish the space next door, so the site is a jobsite and an operating data center at once.

Temporary construction walls split those worlds: they protect finished white space from dust-heavy work and keep cooled air inside the racks that already hold load.

For tall, high-slab halls, StackBarrier™ carries that separation up to 40 feet, and as more of the facility crosses into live operation, the same panels get reconfigured instead of rebuilt.

Renovations raise the stakes, because the room already carries live workloads. Work like swapping cabinets or retuning cooling puts active demolition right next to running systems.

Here, containment isolates the renovation zone instead of exposing the whole hall, and negative-air panels pull dust away from nearby racks rather than letting it drift down the row. When the work wraps, operators often leave the walls up to hold the finished boundary and stage the next phase.

Best Practices for Construction Teams

Containment works best when you plan it before the first wall goes up, not after demolition starts. Wait, and you end up with barriers placed for convenience instead of airflow and access, and the weak spots show up fast in a live hall.

A few practices separate a plan that holds from one that leaks:

• Start in preconstruction. Map the live zones and the high-dust activities before you set a single panel.

• Put doors where crews actually travel. A wall that forces carts the long way gets propped open, and an open door is a broken seal.

• Coordinate the layout with facilities and IT. They know which racks are live and where crews can't cut in.

• Plan for the phases, not just day one. Position walls so you can open and close zones as trades rotate through, with no demo-and-rebuild between stages.

• Match the system to the dust load. High-demolition work wants negative air or filtration tied into the enclosure, not just a sealed box.

Used this way, temporary containment systems become a scheduling tool as much as a dust barrier, giving project managers room to phase the work without stalling other trades.

Should You Use Data Center Containment Systems?

If any part of the data center is live during construction or renovation, you should plan for containment.

A simple equipment swap doesn’t carry the same risk as a dusty renovation next to active racks. Once uptime and airflow are on the line, a cheap barrier costs more than it saves.

Data center containment systems give teams a controlled way to work inside operating facilities. They protect hardware and keep cooling behavior predictable while a phased project moves around them.

For construction and renovation work in live environments, STARC offers modular containment wall systems that replace plastic and temporary drywall with faster installation and reusable panels that can move with the project.

Frequently Asked Questions

Why do data centers need containment during construction?

Data centers need containment during construction because it keeps dust and airflow changes away from live racks, which helps avoid performance issues and downtime.

How do data center containment systems work?

Data center containment systems work by creating defined air paths. They guide cold air to server intakes and return hot air to cooling units, and they fence off construction zones inside the room.

What are hot aisle and cold aisle containment?

Hot aisle containment encloses exhaust air. Cold aisle containment encloses supply air. Each method stops air from mixing, which makes cooling more efficient.

How do containment walls help during renovations?

Containment walls help during renovations by boxing in the work area so cutting and demolition stay inside the enclosure instead of drifting into nearby racks.

Why are modular containment walls better than drywall?

Modular containment walls often beat drywall because they install faster and create less dust, and teams can reuse panels on future jobs instead of tearing them out.

What makes STARC systems suited to live data centers?

STARC systems suit live data centers because they combine slab-to-ceiling panels, gasketed edges, and quick installation, so crews build tight enclosures without long outages.

Can containment systems reduce data center cooling costs?

Yes, containment systems can cut data center cooling costs by keeping conditioned air focused on active racks, which reduces mixing and helps cooling equipment run more efficiently.

How can I get a containment solution sized for my data center?

You can get a properly sized solution by sharing your layout and project phases with STARC so they match panel and door configurations to the way your team plans to work.
