Saint-Gobain begins construction of new float glass and insulation lines in Chennai
The Oragadam site is poised to become Saint-Gobain’s largest multi-business manufacturing hub
Saint-Gobain on Wednesday announced the commencement of construction of its 7th float glass line and 5th mineral wool insulation line in Oragadam, Chennai.
This expansion marks a significant milestone, reinforcing the Group’s strategic commitment to strengthen local manufacturing capabilities and grow in the Indian market, a statement from the company said.
The new float glass facility will have a production capacity of 1,000 tonnes per day, significantly boosting Saint-Gobain’s ability to meet the growing demand for high value-added glass in the construction market. Aligned with Saint-Gobain’s global sustainability goals, the new float line is designed to minimise energy consumption and environmental impact, while using advanced digital capabilities.
Insulation business
Following the acquisition of Rockwool India (Rockinsul) and UP Twiga (Twigainsul), Saint-Gobain has rapidly expanded its insulation business in India. The 5th mineral wool insulation plant will be its largest investment in Asia-Pacific, with a production capacity of 50,000 tonnes. This near net-zero carbon facility will serve the growing insulation needs in building construction across India.
The Oragadam site is poised to become Saint-Gobain’s largest multi-business manufacturing hub that will house facilities for float glass, mineral wool insulation, gypsum plasterboards, plasters and acoustic ceilings, the company’s statement said.
The foundation stone for the larger Oragadam site was laid in the presence of CM MK Stalin last year; the company has now commenced construction of the glass and insulation lines.
