Oldcastle building products

Oldcastle is a leading brand in the construction and building materials industry, widely recognized for its extensive range of concrete products, masonry, and architectural glazing. Founded in the United States, the brand established a reputation for high-quality pavers, bricks, and specialized building solutions used in both residential and commercial sectors. The manufacturing of Oldcastle products occurs across a vast network of facilities, primarily in the United States and Canada, reflecting its localized production model.

Today, Oldcastle operates as a critical division of CRH plc, a global leader in the building materials industry. CRH acquired Oldcastle in 1978, marking it as a significant milestone in its international expansion. The brand now functions under various banners such as Oldcastle APG and Oldcastle BuildingEnvelope, maintaining its status as a cornerstone of the North American construction supply chain while being backed by the financial strength of its Irish parent corporation.
