Seves glassblock owns 36% of the world's glass block production and distribution market. Today, Seves glassblock provides high-quality products, with superior technological contents and strict structural standards, while respecting both the environment and consumer. At the beginning of the 20th century glass blocks were considered as cheap building material and were used primarily in the construction of factories in order to ensure as much natural light as possible. The technology has matured and now the once marginal and construction element has become an artistic expression of light and space. Seves offers a very wide range of glass blocks with different shades and finishes.
