What Börner does

Hans Börner GmbH & Co. KG (BÖRNER) is a family-owned German manufacturer founded in 1945 and headquartered in Nauheim, specializing in custom daylight systems fabricated from acrylic glass (PLEXIGLAS®/PMMA) and polycarbonate. Its product portfolio comprises six core families — Lichtkuppeln (skylight domes), Lichtbänder (continuous light bands), Flachdachfenster (flat roof windows), Dunkelklappen (dark flaps), Fassadenverglasung (facade glazing), and Sonderkonstruktionen (special constructions including stadium roofs, large-area glazing, pyramids, and outdoor canopies). The technical platform is built on in-house plastic processing capabilities including blow molding, thermal forming, polishing, and joining techniques, producing multi-layer systems that achieve 75-83% light transmission and certified anti-penetration (GS-BAU-18), smoke/heat extraction (DIN EN 12101-2), and GEG energy-performance compliance.

The business operates a direct B2B and B2C sales model with a quote-based pricing structure: customers specify product type, dimensions, and equipment needs through a website product finder, after which the company provides consultation, custom manufacturing, installation, and ongoing maintenance or renovation services. The customer base spans four primary segments — private homeowners, industrial and commercial builders, architects and planners, and public/stadium projects — served primarily in the DACH region, with stadium roofs exported worldwide. No subsidiaries, institutional investors, or external funding are disclosed; the entity operates as a GmbH & Co. KG under family ownership.

No financial figures, headcount data, or AI/ML capabilities are disclosed in available source material. The company's strategic positioning is grounded in 80+ years of accumulated plastic-processing expertise, certified regulatory compliance, and the ability to deliver custom-made architectural daylighting solutions in small or large quantities from a single German manufacturing site.
