Tvitec sees itself as a partner for façade constructors, architects and designers. Tvitec is committed to environmental sustainability, looking for ways to increase energy efficiency and reduce the impact on the environment. Tvitec high-performance and eco-efficient glass products are present in more than fifty countries on all five continents around the world. Tvitec is one of the few industries in Europe and in the United States with capacity to produce large insulating glass units up to 12 meters (oversize glass units).
In 2022, Tvitec System Glass acquired Cricursa, uniting two of Spain’s leading architectural glass specialists. The integration combines advanced flat and coated glass production with nearly a century of expertise in high-precision curved glass, strengthening the group’s ability to deliver large-format, high-performance glazing solutions for complex and iconic projects worldwide.
Products
Duritec
SEND INQUIRY
Glass subjected to a heat process (Tempering, Tempering + HST or Heat Strengthened) which increases the thermal and mechanical resistance. The tempered panes get the products as safety glass. In case of rupture, its fragments will be harmless.

Lamistar
SEND INQUIRY
Safety glass formed by two or more pieces of glass joined by aninterlayer sheet. The laminated glass could be manufactured with basic panes annealed or “Duritec” to reach the required safety and mechanical characteristics. In case of rupture of one or both panes, the fragments will remain attached to the interlayer. Besides the ultraviolet rays will be reduced.

cricursa Curved Glass
SEND INQUIRY
Discover precision and performance in every radius with our advanced curved glass solutions — from annealed Crisunid® to toughened and heat-strengthened Critemp®.
More details ...
Curved annealed glass is manufactured by slowly heating flat glass up to the softening temperature, around 550ºC, when the glass starts slumping due to gravity on the customized mould.
Once the desired geometry has been achieved, the glass is slowly cooled. Known as “annealing”, this key phase determines the visual quality and structural properties of the final product.
Annealed glass is versatile and allows for a vast range of shapes, textures and forms in architecture.
Curved Toughened / Heat Strengthened - Critemp®
Curved toughened glass, also known as tempered glass, is manufactured using a fast heating and quenching process. The glass is heated up to 600ºC, curved by oven rollers, and then quenched or cooled rapidly.
This process introduces stresses in the glass, improving its overall material strength.
While not as versatile as annealed curved glass, toughened glass employs a faster production process and enables the use of the best Energy Efficient coatings such as Low-E and High Selectivity coatings. Heat strengthened glass is very similar and produced in the same oven, but quenched more slowly.
