The world's largest manufacturer of glass blocks for architecture and design.

About Seves Glass Block

The history of glass production in northern Bohemia's Duchcov dates back to 1912. Today, the company is a leading global manufacturer of glass blocks with a broad product portfolio: in addition to standard blocks, it offers designer blocks favored by architects and technological blocks with highly functional properties – such as photovoltaic, thermal insulating, fire‑resistant, bulletproof, and security blocks. Sustainability in production, a key value for businesses within the Progresus group, is achieved primarily through glass recycling and upcycling of second‑grade products.

A strong brand, a focus on R&D, the production of technologically advanced products, and collaboration with architects and end‑users form the foundation for operations in more than 100 countries across six continents. Thanks to a stable customer base, the company has achieved annual revenues of up to 1.4 billion CZK in recent years. Most of its sales are generated in European and North American markets. The company employs over 200 people in the Czech Republic and Italy, with a production capacity of 29 million glass bricks annually in various sizes and shapes.
