Core offering

Sedak manufactures oversized flat and curved insulating and safety glass up to 3.6m x 20m for international architecture, marine, and rail projects from a 71,000 sqm facility in Gersthofen, Germany. The company produces a full range of large-format architectural glass — facade glass, glass roofs and floors, balustrades, glass stairs — together with marine glazing (hull, superstructure, bridge, pool windows) and rail glazing (windshields, side windows, cab windows). Its branded innovations include sedak tempered+ (anisotropy-free tempered glass), sedak multicurved (3D-bent glass without molds), sedak isopure (transparent-spacer insulating glass), sedak secuprotect/isosecure (bullet-resistant glass), and sedak ballistic glass HMG (5x BR7), with bespoke product specifications quoted per project.

Product overview

Sedak is a premium glass processor specializing in oversized architectural glass products up to 3.6m × 20m in flat and curved formats. The company operates as a single-source manufacturer offering the complete glass expertise from a single facility: CNC machining, coating, digital printing, tempering, lamination, bending (cold, thermal, gravity, and multicurved 3D-bending), and insulating glass production. The product portfolio centers on sedak tempered+ (anisotropy-free tempered glass), sedak multicurved (3D-bent glass without molds), sedak isopure (insulating glass with transparent spacers), sedak secuprotect and sedak isosecure (bullet-resistant glass up to BR7 NS), sedak ballistic glass HMG (5x stronger than BR7), sedak clear-edge (laminated glass edge protection), sedak groove grinding (decorative grooving), sedak gold printing (real gold digital printing), sedak vogelschutzglas (bird protection), and sedak gsp (opaque facade glass). Beyond these branded innovations, Sedak produces standard insulating glass, safety glass, facade glass, glass roofs, balustrades, glass stairs for architecture, as well as marine glazing and rail glazing for transportation sectors. The company was founded in 2007 and operates from a 71,000 sqm production facility in Gersthofen, Germany.

Others

• Sunglass Industry s.r.l. Sunglass Industry is the Italian curved-glass production subsidiary of Sedak, but operates as a distinct brand serving marine and architectural curved glazing customers independently. Listed for completeness as a group-entity peer serving the same curved-glass market from Italy.

Broad incumbents

• Schott AG: Schott is a German specialty glass and glass-ceramics manufacturer with deep technical expertise in architectural, security, and technical glass. It competes with Sedak in high-performance architectural and security glazing, with strong R&D and global reach across multiple glass sub-segments.
• Guardian Glass: Guardian Glass is a global float and processed glass manufacturer with architectural, interior, and security product lines. It overlaps with Sedak in coated IGUs and architectural facades, but does not match Sedak's specialization in oversized or curved premium formats.
• Pilkington (NSG Group): Pilkington is a major flat and processed glass producer with broad architectural, automotive, and technical glass offerings. It is a broad incumbent competing in architectural IGUs, coated glass, and laminated safety glass, though its focus is broader and less specialized in oversized premium formats.
• Saint-Gobain Glass: Saint-Gobain Glass is a global leader in flat glass and value-added architectural glazing, including oversized formats, coated glass, and acoustic/safety products. As a broad incumbent, it offers a wider portfolio than Sedak but overlaps in premium architectural facades, IGUs, and security glazing.
• AGC Glass Europe (Asahi Glass): AGC Glass Europe is a major flat glass and processed glass manufacturer with broad architectural, automotive, and specialty offerings. It competes broadly with Sedak in high-performance architectural glazing and security glass, though AGC is not specialized in the oversized format niche.

Direct peers

• Cricursa: Cricursa is a Spanish curved glass specialist serving architectural facades, with deep expertise in cold and hot-bent curved glass for iconic projects. It directly competes with sedak in the curved architectural glass segment, including projects for starchitects and luxury developments.
• Okalux GmbH: Okalux is a German specialty glass manufacturer focused on functional architectural glass for daylighting, solar control, and thermal performance. It is a direct peer in the value-added European architectural glass segment, with overlapping product capabilities and customer base in premium facades.
• Glas Trösch: Glas Trösch is a Swiss-family-owned specialty glass processor offering architectural, security, and acoustic glass solutions across Europe. Like Sedak, it serves premium architectural projects with value-added processing (tempering, lamination, coatings) and competes in the same oversized and security glass niches.
• Eckelt Glas: Eckelt Glas is an Austrian specialty glass manufacturer focused on architectural structural glass, insulated glass units, and security glazing. It is a direct peer in the premium DACH-region architectural glass market, with overlapping capabilities in IGUs, laminated safety glass, and security products.
