In refractory performance, consistency begins at the raw material level. As part of our new lightweight monolithic facility operation, HWI has made a significant investment in a new, purpose-built aggregate processing furnace dedicated to our GREENLITE® aggregate production.
GREENLITE® aggregate plays a critical role in the performance of lightweight monolithics and brick, where low density must be balanced with strength, thermal stability, and reliability in service. This new processing furnace allows HWI to better control the aggregate formation process to deliver a consistent, high-quality raw material that supports predictable refractory performance. This enables solutions tailored to specific customer requirements, whether optimizing insulation efficiency or enhancing service life in demanding operating environments.
Quality control is also embedded at every stage of production at Fulton, ensuring that each batch of aggregate meets strict specifications before it enters refractory manufacturing. This systematic approach enhances reliability for customers and reinforces confidence in product performance across installations and operating conditions.
This new aggregate processing furnace adds more than just expansion of capacity—it is a strategic investment in the future of lightweight refractory solutions. By committing to purpose-built infrastructure, differentiated raw materials, and advanced manufacturing technology, HWI continues to strengthen its ability to solve complex customer challenges with precision-engineered refractory products.
The result is greater consistency, improved performance, and a reliable foundation for lightweight monolithics and brick designed to meet the evolving demands of high-temperature industries.
