Open-plan offices, comms rooms, control rooms and trading floors all have the same problem: they need a lot of power and data, and the layout keeps changing. Raised access flooring solves that by lifting the finished floor above the slab and leaving a void underneath for cables and, in some cases, air. When the desks move, the cabling moves with them. You lift a panel instead of chasing a new trench into the screed.
This guide covers how raised access flooring works, which options suit UAE projects, and what to have ready before you ask for a quote.
How a raised access floor is built
A raised access floor has three main parts:
- Pedestals. These are adjustable steel supports fixed or bonded to the slab. Turning the head lets the installer level the floor accurately, even when the slab is uneven.
- Panels. These are usually 600 × 600 mm. They sit on the pedestal heads and can be lifted with a suction lifter to reach the void.
- Stringers (optional). These are horizontal members that connect the pedestal heads. They add lateral stability, which matters more on taller floors and in rooms with heavy equipment.
The gap between the slab and the underside of the panel is the void. The total height from slab to the top of the finish is the finished floor height (FFH). Both figures need to be fixed early, because they affect door thresholds, ramps, stair nosings and lift landings.
Choosing the right panel type
Panels differ in what is inside them, and that affects load capacity, acoustics and cost.
Steel cementitious-filled panels
These are steel trays filled with a lightweight cement core. They are a common choice for offices and technical rooms that need solid, quiet panels with good load performance. They also handle the occasional humidity you get in UAE buildings during commissioning better than a pure wood core.
Calcium sulphate panels
These are dense, solid panels with good acoustic and fire performance. They feel very similar to a structural floor underfoot, which is why many specifiers use them in premium offices and in areas where footfall noise matters.
Woodcore (chipboard) panels
These are lighter and usually cheaper. They work well in dry, controlled office environments. They are less suitable in areas exposed to moisture or heavy rolling loads.
Perforated and grille panels
These are used in data rooms and server rooms that rely on underfloor air distribution. Cool air from the CRAC/CRAH units is pushed through the void and out through the perforated panels in front of the racks. You can place them where they are needed and move them later.
Getting the floor height right
There is no single correct height. The void has to fit what goes under it:
- General offices with power and data only: low-profile systems with small voids are often enough, and they keep thresholds manageable in existing buildings.
- Offices with underfloor air or dense cabling: these need a deeper void so that cable trays do not block airflow.
- Data rooms and comms rooms: these usually need the deepest voids, because cable trays, cooling and containment all compete for space.
In a fit-out of an existing UAE tower, the slab-to-ceiling height is often what limits you. Agree the FFH with the architect and the MEP consultant before ordering. Changing it later means new pedestals.
Load ratings: ask the right question
Raised floors are tested for concentrated (point) loads, uniform loads and rolling loads. In Europe, EN 12825 is the main standard for raised access floors and sets out load classes and test methods. When you compare products, ask:
- What is the rated concentrated load, and what safety factor is it tested to?
- Is the rating for the panel alone, or for the full system with pedestals and stringers?
- Is there a rolling-load rating for server racks, pallet trucks or trolleys?
A floor that suits an office may not suit a comms room with fully loaded racks. Get your equipment loads from the IT or MEP team and share them with your supplier.
Finishes on top of the panels
The panel is only the structure. What people see and walk on is the finish:
- Carpet tiles. This is the most common office choice because they are modular, acoustic and easy to lift locally. Plan how the carpet tile grid relates to the 600 × 600 panel grid so that panels can still be reached without disturbing large areas.
- LVT and vinyl. These suit reception areas, breakout zones and corridors that need a hard, easy-clean surface.
- Anti-static or conductive finishes. These are specified in server rooms and control rooms where static discharge could damage equipment.
- Factory-bonded finishes. Some panels arrive with the finish already applied, which speeds up installation in technical rooms.
Identity Flooring supplies carpet tiles, LVT and vinyl, including the Oneflor-Europe ranges we distribute in the UAE. That means the raised floor and the finish can be coordinated by one supply partner. See the options on our shop and carpet flooring pages.
Installation sequence on a UAE fit-out
A typical sequence looks like this:
- Slab preparation. Clean the slab, check it for level and seal it to control dust.
- Setting out. Fix the grid from a datum so that the panels line up with walls, columns and partitions.
- Pedestals and stringers. Bond or fix them, then level them to the agreed FFH.
- MEP first fix in the void. Cable trays, floor boxes and any underfloor air components go in.
- Panels. Lay the panels, cut them at the perimeter and fit edge trims and ramps.
- Finish. Lay the carpet tiles, LVT or vinyl, then fit the floor-box lids and grilles.
If the void is used for air, it needs to be sealed and cleaned before handover. Coordinate the work so that other trades do not drop debris into the void after the panels are down. Installation can be arranged with your appointed contractor.
Common mistakes to avoid
- Fixing the FFH too late. Doors, risers and lift thresholds all depend on it.
- Ignoring rolling loads. Moving heavy racks across an office-grade floor can crack panels.
- Laying the finish without access in mind. If every panel is covered by fixed flooring, the whole point of access flooring is lost.
- Mixing panel types without a plan. Perforated panels and solid panels need to sit in the right zones.
- Leaving out spares. Order spare panels and finish so that damaged areas can be matched later.
What to send for a quote

Frequently asked questions
What is raised access flooring used for? It creates a void under the floor for power, data and sometimes air distribution. Panels can be lifted to reach services, which makes it popular in offices, comms rooms, control rooms and data rooms.
Can carpet tiles be laid on a raised access floor? Yes. Carpet tiles are the most common office finish on raised floors because they are modular and can be lifted locally. Plan the tile layout around the panel grid so that panels remain accessible.
What height should a raised floor be? It depends on what goes in the void. Power and data only can use a low-profile system. Underfloor air and data rooms need deeper voids. Agree the finished floor height with your architect and MEP consultant early.
Is raised access flooring suitable for server rooms? Yes, provided the panels and pedestals are rated for the rack loads and the finish is suitable for static control. Perforated panels are used where cooling relies on underfloor air.
Does Identity Flooring install raised access floors? We are a supply partner. Installation can be arranged with your contractor, and we can coordinate delivery to suit your programme.
