Why Raised Access Flooring Is Essential for Modern Data Centres in 2025

In the high-stakes world of data centres, where uptime, efficiency, and futureproofing are critical, the choice of flooring can make or break operations. That’s why raised access flooring has become the industry standard — not just for cable management, but for thermal efficiency, maintenance, and more.

???? In this guide, we’ll explore exactly why data centres depend on raised floors — and how to choose the right system.

???? 1. Cooling Efficiency & Airflow Management

Raised floors create a service void that acts as a cold air plenum. HVAC systems deliver cool air through perforated panels exactly where it’s needed — under high-density server racks.

• ✔️ Improves PUE (Power Usage Effectiveness)
• ✔️ Reduces energy costs

Pro tip: Choose panels with vented or perforated finishes for better airflow balance.

???? 2. Flexible Cable & Power Routing

As your server room evolves, so does your cabling. Raised access flooring gives IT teams complete flexibility to run:

• Fibre optics
• Ethernet
• Power cabling
• Fire suppression conduits

Need to upgrade or reroute later? No problem — just lift a panel.

????️ 3. Load Capacity for Server Racks

Heavy-duty data racks demand high-strength panels. Steel-encapsulated panels offer industry-leading structural performance with load classes up to 13kN/m², depending on your configuration.

Look for PSA MOB PF2 PS/SPU certified panels for maximum reliability.

⚡ 4. Anti-Static & Grounding Protection

Prevent costly hardware failures or data loss with electrostatically dissipative (ESD) flooring. Anti-static properties are built into the surface finish or top layer — especially important in high-density computing environments.

???? 5. Maintenance & Uptime Advantages

Access floors reduce downtime by allowing rapid intervention. Need to swap a cable or inspect a power bank? No drilling, no trenching. Just pop the panel and get to work.

FAQs

What type of raised flooring is best for data centres?

Steel-encapsulated panels with anti-static finishes are generally preferred due to their strength and grounding performance.

How is airflow managed through raised flooring?

Cold air is directed under the floor and distributed through perforated panels to optimize cooling under specific racks.

What load should data centre panels support?

Data centres typically require raised floors to support 8–13kN/m² or more. Always check the load class certification (PSA or EN).

If you're planning a refurbishment, fitting out an office, or setting up a data center, a raised access flooring system can be the perfect solution for managing cables, airflow, and future flexibility. Done right, it’s a fast and cost-effective upgrade — but getting the installation process right is key to performance and durability. Here’s a full step-by-step guide.

What Is Raised Access Flooring?

Raised access flooring is a type of modular floor structure that sits above the building’s original floor slab. It uses adjustable pedestals and panels to create a void for cables, electrical systems, and HVAC equipment — keeping everything hidden but easily accessible.

• Office spaces
• Server rooms
• Retail fit-outs
• Control rooms

Step 1: Preparation

Before any materials arrive, start with a clean, flat, and dry subfloor.

• Sweep and clean the subfloor thoroughly
• Mark out any zones, walls, or fixed items
• Confirm final floor heights (including panel + pedestal + adhesive thickness)
• Check for moisture issues — access flooring needs dry conditions

Tip: A good laser level will make your life much easier when setting heights!

Step 2: Setting Out the Grid

Using your floor plan, mark the starting points:

• Find the center point or key axis of the room
• Snap chalk lines or laser lines across the room to create a master grid
• Set pedestals where the panels will intersect (typically 600mm x 600mm)

Step 3: Fixing the Pedestals

Most raised floor pedestals are glued with a two-part adhesive, while others may use mechanical fixings.

• Mix adhesive as per manufacturer’s instructions
• Apply to the base of each pedestal
• Press firmly into position along your grid lines
• Allow the adhesive to cure fully (this is critical for stability!)
• Adjust the pedestal heads to the correct height using a spirit level or laser level

Step 4: Installing the Stringers (if required)

Some systems use additional stringers — metal bars between pedestals — for extra rigidity, especially in heavy-load areas.

• Clip, bolt or screw the stringers to the pedestal heads
• Check for squareness regularly as you go

Step 5: Laying the Access Floor Panels

Once the pedestal system is stable:

• Start placing floor panels carefully into the grid
• Ensure each panel sits securely on the pedestal head gasket or fixing plate
• If required, screw down the panels
• Stagger cuts and panels where needed for strength
• Adjust heights if needed to eliminate rocking panels

Step 6: Trimming and Finishing

At the edges of the room:

• Cut panels neatly using a circular saw (wear dust protection)
• Leave expansion gaps against perimeter walls
• Install skirting trims or edge details as required

Common Mistakes to Avoid

• Rushing the pedestal setting out — leads to poor alignment later
• Skipping curing time on adhesives
• Not checking the level constantly across the floor
• Cutting panels without dust control

Why Proper Installation Matters

A poorly installed access floor will develop squeaks, movement, uneven gaps, and costly rework later. A proper install guarantees:

• A safe, professional appearance
• Smooth cable management
• Easier future maintenance
• Longer lifespan

Conclusion

Installing a raised access floor isn’t difficult with good preparation, careful layout, and attention to detail. By following the right steps, you'll create a solid, level platform ready for whatever your project needs — from high-spec offices to high-load data centers.
