What Is a Calcium Sulfate Raised Floor?
Structure and Materials
A Calcium Sulfate Raised Floor has a strong core. This core is made from a mineral called gypsum. Makers mix gypsum with plant fibers and pulp. They press this mix into panels. Then, they dry the panels in special ovens. This makes the panels strong and steady. Each panel has a steel sheet on the bottom. The top has a tough finish. You can pick different sizes like 600mm x 600mm or 500mm x 500mm. You can also choose thicknesses like 25mm or 30mm. The edges are sealed to stop water and damage.
Tip: The solid core and careful building help the floor stay flat and not swell, even when the room gets more or less humid.
Key Properties
A Calcium Sulfate Raised Floor gives you many good things:
It is very strong and holds heavy machines.
It has a Class A1 fire rating, so it will not burn, even if it gets hotter than 1,000°C.
It does not soak up much water, so the panels do not swell or break.
It blocks sound well, so your data center is quieter.
The core does not burn, which makes it safer.
The materials are good for the environment and help you build green.
Here is a table that shows some main physical properties:

Calcium Sulfate Raised Floor Benefits
Fire and Moisture Resistance
Data centers need strong fire safety. Calcium Sulfate Raised Floors give top fire protection. The panels have a mineral core that will not burn. This floor helps keep your equipment safe if there is a fire. Check the fire safety ratings below:
Fire Resistance Rating | Standard |
|---|---|
A1 | EN 13501-1 |
Class A | GB 8624 |
Moisture can hurt server rooms. The mineral core stands up to normal humidity. You do not need to worry about swelling or breaking from daily moisture. Here are some facts about moisture resistance:
Calcium sulfate raised floors handle normal humidity changes.
They are not good for places with lots of water or high humidity all the time.
Too much moisture for a long time can cause swelling, cracks, mold, and edge seal problems.
This floor protects your data center from fire and daily moisture. Do not use it in places with water all the time.
Load Capacity and Durability
Heavy machines need strong floors. Calcium Sulfate Raised Floors hold big server racks and carts. These floors have high load strength and last a long time. See the table below for more details:
Flooring Type | Concentrated Load | Uniform Load (kg/m²) | Rolling Load (10 passes) | Typical Application |
|---|---|---|---|---|
Calcium sulphate core | 4000–5000 N | 1200–1500 kg/m² | High | Data centers, telecom, industrial |
Encapsulated calcium sulphate | 5000–6000+ N | 1500–2000 kg/m² | Very High | Tier III & IV data centers, critical |
You want your floor to last for years. Calcium sulfate panels stay strong for decades. Compare how long different raised floors last:
Floor Type | Expected Lifespan |
|---|---|
OA Floor | 5-8 years |
Antistatic | 10-15 years |
12-18 years | |
Calcium Sulphate | 20+ years |
This floor supports heavy loads and lasts over 20 years. You will not need to fix or replace it often.
Acoustic and ESD Performance
Loud noise can bother your team and make it hard to focus. The dense core of a Calcium Sulfate Raised Floor soaks up sound. You hear less echo and hollow noise in your data center. This makes your work area quieter and nicer.
Static electricity can hurt electronics. You need good ESD protection. Calcium sulfate raised floors give you two choices:
Conductive flooring is best for strong static control. It keeps your equipment safe from sudden static shocks.

Comparison with Other Raised Floor Types
Steel vs. Calcium Sulfate
You might wonder how steel floors and calcium sulfate floors are different. Steel floors usually cost less, about 20% cheaper. Their price can go up or down if steel prices change. Calcium sulfate board prices do not change much. Steel floors are good for fire safety, but calcium sulfate floors have the best fire rating and make less smoke. Check the table below to see how they compare for fire safety:
Fire Performance | Calcium Sulfate Floor | Steel Cementitious Floor |
|---|---|---|
Combustibility | EN 13501-1 Class A1 (Non-combustible) | EN 13501-1 Class A2fl-s1 |
Smoke Emission | s1 low smoke emission | s1–s2 smoke emission |
Thermal Stability | Stable up to 1000°C | Stable up to 600–800°C |
Toxic Gas Emission | Very low VOC & toxic gas | Low toxic gas |
Public Building Suitability | Airports, hospitals, schools | Commercial & technical buildings |
Steel floors help you save money, but calcium sulfate floors give better fire safety and steady prices.
Woodcore vs. Calcium Sulfate
Woodcore floors are light and simple to put in. They are good for offices but do not handle water as well as calcium sulfate floors. Woodcore panels have okay moisture resistance. They are not great for wet places. Calcium sulfate panels are better at stopping water damage. Look at the table below:
Type of Floor | Moisture Resistance Properties | Additional Notes |
|---|---|---|
Calcium Sulfate | Superior moisture resistance | Encased in steel, reduces noise |
Woodcore | Average moisture resistance | Lightweight, lower fire rating |
Both types can hold heavy things. Calcium sulfate panels can hold up to 2500 lb. Woodcore panels usually hold 1250 lb.
Floor Type | Concentrated Load Capacity |
|---|---|
Wood Core Raised Floor | 1250 lb |
1250 lb (up to 2500 lb) |
Cementitious and Aluminum Options
Cementitious and aluminum floors are strong choices. Cementitious floors can hold a lot of weight and do not break easily. Aluminum floors are light and easy to move around. Calcium sulfate floors keep their shape, hold weight well, and are nice to walk on. Cementitious floors are best for data centers and telecom rooms. Calcium sulfate floors are good for offices, libraries, and schools.
Flooring Type | Advantages | Typical Applications |
|---|---|---|

Data Center Operations Impact
Cooling and Airflow
Servers get hot and need to stay cool. A Calcium Sulfate Raised Floor helps move air under the floor. You can put cooling vents and panels where you want. Air flows in the space below the panels. This helps send cool air to hot spots. You can change the setup if you add new equipment. Many data centers use underfloor air to save energy and protect equipment.
Tip: Perforated panels help air move better. You can move them if your cooling needs change.
Cable Management
Cables can get messy in a data center. Raised floors give space under the panels for cables. You can run power, data, and fiber cables neatly. This keeps the room safe and easy to clean. You can lift panels to reach cables fast. You do not have to move heavy racks. Good cable management stops accidents and keeps equipment working.
Cable Management Benefits | Description |
|---|---|
Easy Access | Lift panels for quick repairs |
Neat Layout | Reduce cable clutter |
Flexible Routing | Change cable paths easily |
Safety and Compliance
Data centers must follow safety rules. Good raised floors have strong fire ratings. They slow down fire and smoke. Fire-resistant and anti-static floors protect your equipment. You meet safety rules and keep staff safe. Anti-static panels stop static shocks that hurt servers. Always check local codes before you install your floor.
Fire-resistant panels help you follow fire rules.
Anti-static floors protect sensitive electronics.
You must follow building codes and industry standards.
Maintenance and Longevity
You want your floor to last many years. Clean panels with a soft mop or vacuum. Wipe up spills right away. Check panels every month for damage or loose parts. Look at pedestals and grounding to stay safe. You can replace one panel if it breaks. ZILI says to get a pro inspection every year. With good care, your floor can last over 20 years.
Note: Regular cleaning keeps your floor strong and safe. You save money by stopping big repairs.
