UltraCool Fiber Cement Roofs

High Solar reflectance roofs that reduce indoor temperature by up to 8°C.
UltraCool Fiber Cement Roofs offer advanced thermal protection, helping reduce indoor temperatures by up to 8°C*. With a high Solar Reflectance Index (SRI) of 99**, they reflect solar heat to minimise heat gain and maintain cooler interiors. Suitable for homes, commercial buildings, and industrial facilities, they deliver long-lasting strength combined with superior thermal comfort.

How long will the cooling effect of Charminar BirlaNu UltraCool last?

Charminar BirlaNu UltraCool sheets' cooling effect will remain up to 4 years as per accelerated heat-rain cycles and UV exposure test performance.

What type of coating is used on Charminar BirlaNu UltraCool?

It's a 100% acrylic polymer coating specially designed for Charminar BirlaNu UltraCool roof.

Will rains wipe off the polymer coating responsible for cooling?

No, special binders, pigments and additives are used for coating, which is water repellent and prevents from wiping off due to rains.

Can I purchase summer protection coolant paint and apply it on a normal roof?

Coolant paint in the open market is not sustainable and does not last for longer periods. Also, performance is not equivalent as Ultracool has a higher solar reflectance index (SRI), which decides the temperature reduction. Higher the SRI number, more the temperature reduction.

How much temperature reduction can UltraCool Fiber Cement Roofs provide?

Charminar BirlaNu UltraCool roofs can reduce indoor temperatures by up to 8°C by reflecting solar heat and minimising heat transfer.

What does SRI mean in roofs?

SRI or Solar Reflectance Index measures how effectively roofs reflect heat, with higher values delivering better cooling performance.

Can UltraCool roofs reduce electricity consumption?

Yes, lower indoor temperatures can reduce dependence on fans and air-conditioning, leading to energy savings.

Is UltraCool Fiber Cement Roofing different from regular Charminar BirlaNu sheets?

Yes, UltraCool sheets feature a specialised heat-reflective coating that delivers superior thermal performance compared to standard fiber cement roofs.

How much can UltraCool Fiber Cement Roofs reduce indoor temperature?

Ultracool roofs can reduce indoor temperatures by up to 8% by reflecting solar heat, depending on roof design, climate conditions and installation quality.
