Rockwool to Invest Rs 550 Crore in Tamil Nadu for Largest India Factory

Rockwool

Denmark-based Rockwool, a leading global insulation producer, is set to establish its largest factory in India with an investment of Rs 550 crore. The new facility will be located in Cheyyar, Tamil Nadu, approximately 90 km from Chennai, and is expected to significantly enhance the company’s presence in the Indian market. This expansion comes in addition to Rockwool’s existing factory in Dahej, Gujarat. 

Rockwool, which reported revenues of €3.6 billion and operates in 40 countries, views this new investment as a strategic move to capitalize on Tamil Nadu’s leadership in various sectors. The state’s contribution to one-third of India’s GDP makes it an ideal location for the company’s growth plans. 

The decision to establish the factory was confirmed during a meeting between Rockwool’s top executives—Board Chairman Thomas Kahler, Asia Managing Director Darryl Mathews, and India Business Unit Director Vinay Pratap Singh—and Tamil Nadu’s Chief Secretary N Muruganandham. The facility, to be situated in the SIPCOT Industrial Park in Cheyyar, will be 25% larger than the company’s Gujarat factory, covering a 56-acre plot. 

“We aim to begin commercial operations in the first half of 2026, with the ground-breaking ceremony scheduled for November,” said Mathews. The new factory will produce approximately 50,000 tonnes of non-combustible, recyclable, and long-lasting stone wool insulation materials annually. These products, similar to those manufactured in Gujarat, will cater to the domestic market, particularly for fire applications. 

Mathews also noted that the new factory would significantly boost Rockwool’s revenue contribution from India, which currently accounts for less than a single digit of the company’s global turnover. The facility will create around 150 jobs, further contributing to the region’s economic growth.
