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 Ultracool last?

Charminar 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 Ultracool?

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