India: Rockwool India has commenced construction of a new US$65.5m mineral wool insulation plant in Cheyyar, Tamil Nadu. The Hindu newspaper has reported that the plant will produce 50,000t/yr of stone wool insulation from its commissioning in early 2026. The plant will employ 150 people and will overtake the Dahej, Gujarat, plant as Rockwool India’s largest. The subsidiary of Denmark-based Rockwool opened the 40,000t/yr Dahej plant in 2011.
Managing director Darryl Mathews said “Our non-combustible products are witnessing increasing demand in India. Additionally, we will introduce dual-density technology aimed at residential renovation and construction projects.”
Group chair Thomas Kähler said “I am pleased to announce our second investment in India. This expansion is just the beginning, as we anticipate further developments in response to the growing demand for our products.”
