Heat-Reflective Paint for Data Centres
Buildings like Data Centres with metal, RCC, or membrane roofs get very hot when the sun shines on them. Research shows that uncoated roofs can heat up to 65–75°C, which causes:
- The indoor server room temperature to rise, pushing cooling systems to their limit
- CRAC/CRAH units and chillers to work harder, raising PUE (Power Usage Effectiveness)
- More electricity to be used for cooling, which increases operating costs
- Servers and hardware to run hotter, shortening equipment lifespan
- A higher risk of heat-related shutdowns and unplanned downtime
If there is no proper way to control roof heat, uptime becomes harder to guarantee, energy costs rise, and critical infrastructure is put under unnecessary thermal stress.
COOLROOF® Paint Solution
COOLROOF® Paint is a special coating that reflects most of the sun’s heat (up to 95%) and has a high Solar Reflectance Index (SRI ≥122). This helps keep the building cooler inside, saves energy, and supports the stable, controlled environment that data centre operations depend on.
| Research Data | Before COOLROOF® Paint | After COOLROOF® Paint |
| Roof Surface Temperature | 65–75°C | 38–45°C |
| Cooling Energy Usage | Higher due to excessive solar heat gain | 20–25% reduction in cooling load |
| Equipment Downtime | Higher risk of heat-related shutdowns | Fewer heat-induced disruptions |
| Return on Investment | N/A | Up to 18 months |
| Surface Durability | Minimal to moderate durability | Extended, long-lasting durability |

Trusted Across Critical Infrastructure – ICICI Bank, Hyderabad & Jaipur
COOLROOF® Paint has already been applied at ICICI Bank branches in Hyderabad and Jaipur, where the coating helped reduce indoor heat load and ease pressure on cooling systems in high-footfall, temperature-sensitive environments. The same reliability that critical banking infrastructure depends on now extends to data centres, where consistent thermal control is even more essential to protecting uptime.
