How it all began…

1896Founding of a glass factory in Haselbach/Thuringia by J. and H. Schuller

Haselbach: J. and H. Schuller found a glass factory in Haselbach/Thuringia and have it registered as “Glasfabrik Haselbach” on September 16. It is renamed “Wernerhütte” a few years later. Production of glass tubes and marbles; from 1901 also tablet and test tubes (manufactured by the in-house glassblowing shop).

1921Founding of “Thüringische Glaswollindustrie” (Thuringian glass wool industry)
Founding of “Thüringische Glaswollindustrie” (Thuringian glass wool industry)

Hamburg/Lauscha: The Hamburg-based glass eye dealers Cordts and Goldmann have been in contact with glassmakers in Lauscha, Thuringia for a long time. Together they discover that the angel hair used as a Christmas decoration causes the wax of the candles to melt since it reflects the heat radiating from lit candles. Glass fiber hair is now used for heat insulation. On November 11 in Lauscha, they found the “Thüringische Glaswollindustrie” (Thuringian glass wool industry) together with Septimius Koch and Karl Greiner-Petter. The company focuses on large-volume production of glass wool, selling it worldwide from the trading hub Hamburg.

1924Steinach: expansion of production space

Steinach: Business develops so positively, more production space is required. Production is relocated from Lauscha to Steinach and expanded. More than 10,000 kilograms of glass wool are produced each day!


Business develops exceptionally well. Vitrulan insulation products are used for trains of the German national railway company, the piping of big ships, in sugar factories and oil refineries.

1931First wall covering made of fine glass weave

Steinach/Hamburg: a genuine innovation! The company produces the first wall covering made of fine glass weave – from colored glass.

The name “Vitrulan” is registered as a trademark (derived from the Latin “Vitrum = glass” and “Lana = wool”.)


Expansion in Haselbach: glass staple fiber sliver replaces asbestos, more than 250 tons of glass fiber is produced each year; a new glass drawing facility and batch house are built.


Steinach/Haselbach: sequestration of the Steinach company by the USSR after the war for reparation payments.

1958Building of the Marktschorgast plant

Hamburg/Marktschorgast: despite the loss of the Steinach factory, Hans F.C. Cordts continues business operations. He even manages to win VW as customer, which fits Vitrulan’s insulating products into the VW Beetle. Glass fabrics with a reinforcing finish for bitumen membranes sell well. To meet the increasing requirements of bitumen membranes, Hans F.C. Cordts decides to build his own factory, which is opened in Marktschorgast in Upper Franconia with 3 employees in May 1958.


Marktschorgast: development of special heat insulation components with synthetic coating for VW. Additional innovations: glass fabric for lamp shades and roofing membranes as well as the first glass deco fabrics.


1962, Hamburg: Hans F. Cordts’ father appoints him sole managing director of the “Gesellschaft Thüringische Glaswollindustrie” (Society of the Thuringian Glass Wool Industry), formerly S. Koch GmbH. Until the end of the sixties, the Hamburg office is responsible for the marketing all products manufactured by the Marktschorgast plant as well as by various service providers.


1968, Haselbach: production start of glass compounds for neon tubes and semi-conductors.

1973Management change

Hamburg/Marktschorgast: Looking back on over 50 years of company history, the company founder retires and hands over complete control of the business to his son, Hans F. Cordts, merchant and engineer, who transfers all business operations from Hamburg to Marktschorgast. In addition to expanding the export business (e.g. Scandinavia, Austria, Netherlands), other areas of application are explored: lamp shades made from glass fabric, first wall coverings made of textile glass, and glass mesh fabrics.


1978: “Textiglasfabrik Hans F.C. Cordts” is renamed “Vitrulan Textilglas GmbH” and the name “Vitrulan” is registered as a trademark. A new 8,000 sqm production hall is opened in Marktschorgast to meet the huge increase in demand for glass deco fabrics.


Zeil am Main: the former AEG Telefunken plant in Zeil am Main is purchased and subsequently transformed into a location for the production of mesh fabrics for external thermal insulation composite systems.


Marktschorgast/Zeil: both plants are operating at full capacity. They produce glass deco fabrics, glass reinforcement fabrics, glass fabric corner beads, bitumen glass fabric as a protective and carrier material for onshore and offshore pipeline insulation, glass insulating products, braided textile glass for packaging material, ribbons, and ready-made products.

1992Haselbach: Following German reunification, the shareholders of Hans F. Cordts take over the Haselbach glass factory in Thuringia on May 8, 1992.
Haselbach: Following German reunification, the shareholders of Hans F. Cordts take over the Haselbach glass factory in Thuringia on May 8, 1992.

Under the former ownership of the Schuller company, the factory had already supplied the Marktschorgast plant during the GDR era. At the time of the takeover, the Haselbach glass factory specializes in the production of glass rods and the spinning of glass fibers. With high investments in buildings and production facilities, the location is transformed into an efficient manufacturing plant for bitumen-saturated glass fabric, reinforcement fabric, staple fibers and other technical textile products.


Melk: in Melk/Austria, a glass deco fabric production plant is purchased from competitor Tasso and converted into a production site for mesh fabric.


1995, Marktschorgast: Peter Cordts, son of Hans F. Cordts, is appointed technical managing director. The company is certified according to DIN EN ISO 9001.

1996100th anniversary in Haselbach

Renovation is completed just in time to celebrate 100 years of “Glaswerk Haselbach”: investments of some 20 million German marks, demolition of the old facility maintenance building and the building of a new big warehouse. The glass melting furnace for glass tubes and rods in Haselbach is shut down and investments made in the building of a cutting-edge glass staple fiber spinning mill.
