The core capabilities are the lamination of glass, edging, and the company’s know-how of producing glass components with additional functional and decorative elements. That knowhow has been deriving from sedak’s intense research and development.

With its large size glass units, sedak opens up extraordinary architectural design possibilities combined with economical advantages for façade constructors, architects, and contractors. sedak’s production has been optimized for glass up to 20m and the associated weights. All finishing steps are handled in-house e.g. with the new, fully automated insulating glass line that produces insulating glass units up to 102mm thick.

The enormous formats are available as safety or insulating glass. All products are obtainable colored, printed, specially treated for a thermal or sound insulation, as well as for sun protection. The glass units are delivered worldwide. sedak products are used for façades, glass roofs, balustrades, and stairs as well as for custom-made products, and the shipbuilding sector (e.g. as glass pools, walkable skylights, rails, for the hull glazing, or the ship’s floor). As full supplier for glass up to 20m, sedak sees itself as a partner for architects, designers, and façade constructors.
