“We’ve always been an important partner to the large window manufacturers in Finland. Listening to their needs and responding has helped us stay competitive in this market,” Tommi Nousiainen, CEO of PLG in Finland, explains. “We were not specifically looking for a tempering furnace. But when our customers began to require high-quality tempered glass, we moved swiftly ahead with an entry-level Glaston RC model. Since then, we have already been able to upgrade the line twice in response to the rapidly evolving market.”
