The company announced Tuesday that it has begun renovating its plant to begin production of fiberglass insulation products during the second quarter of this year.

Greg Silvestri, president of CertainTeed Insulation, says the company is investing more than $30 million to re-engineer the plant’s furnace and restart related production lines to give it greater flexibility to support its growing business needs.

CertainTeed employs about 6,000 people in 65 facilities in the U.S. and Canada. It is a subsidiary of Saint-Gobain, the world’s largest building materials company.
