Saint-Gobain has announced that its subsidiary SEFPRO will discontinue production of its alumina-zirconia-silica (AZS) refractory line at its Falconer, New York, facility, a move that will result in the loss of 79 union and salaried positions. Production is expected to cease in August as the company continues to align its operations with broader strategic objectives.

SEFPRO, formerly known as Monofrax, is a long-established manufacturer of fused-cast refractory materials used in glass melting furnaces and other high-temperature industrial applications. The company’s product portfolio includes high-zirconia, alumina, and chrome-based refractories that serve glass manufacturers worldwide.

According to company officials, the closure will affect only the AZS production line, while other manufacturing activities at the Falconer facility will continue. Saint-Gobain stated that the decision followed a thorough review of its business priorities and long-term operational strategy.

“This will not impact every product line at Falconer, and the facility will continue the production of its remaining product lines,” the company said, adding that it is committed to supporting affected employees throughout the transition process.

The announcement comes amid a challenging market environment for Saint-Gobain. In its first-quarter 2026 financial results, the company reported a 2.3% decline in sales, citing unfavorable weather conditions across North America and Europe during the early months of the year. North American sales experienced a sharper decline of 11.3%, reflecting continued weakness in regional construction and industrial markets.

Saint-Gobain has indicated that it expects market conditions in North America to remain difficult during the first half of 2026, prompting ongoing efforts to streamline operations and focus resources on key business segments.
