The restoration glasses TIKANA®, RESTOVER® and GOETHEGLAS will be focused by the technology group SCHOTT at its premiere at Monumento, the trade fair on monument preservation, to be held in Salzburg, Austria, from January 28 - 30, 2016 (Hall 10, Booth 124).

With these types of products that are produced using authentic techniques, architects cannot only restore original historical monuments from different eras.These glasses can also be processed in many ways and thus help to meet contemporary constructional requirements and capabilities –from UV protection to thermal insulation.

The restoration of old monuments is a delicate task for a number of reasons. On the one hand, it is of high importance for the monument preservation authorities to preserve   monuments as extensively as possible. On the other hand, economic and functional aspects should also be taken into consideration, especially when such a building can only be retained by changing its use.

Fourcault tradition and SCHOTT expertise

SCHOTT offers a wide range of restoration glasses that are machine-drawn using the traditional Fourcault process to meet the many different requirements for glazing monuments. Through this historically authentic production process, in combination with more than 130 years of expertise in materials and technology at SCHOTT, glass features such as fluctuating thickness, flatness or streaks can be matched exactly to the appearance and character of the historic original glass. It is thus possible to recreate the typical appearance of window glasses from different eras.

The Fourcault glasses have also received the European Technical Approval ETA-12/0159 from the Deutsches Institut für Bautechnik (German Institute of Building Technology). All SCHOTT restoration glasses can be processed into insulating glass, laminated glass or – similar to tempered safety glass – thermally strengthened glass. Architects can thus implement current structural requirements ranging from thermal insulation, solar and UV protection to secure overhead mounting, but also burglary prevention and sound insulation. Proven solutions include coatings and films, inert gas fillings for the space between the panes or a variety of colored spacers inside the insulated glass laminate.

The restoration glass SCHOTT GOETHEGLAS has the typical irregular surface of window glasses from the 18th and 19th century.

TIKANA®: for Classic Modernism and the Bauhaus style

The façade of the former department store Schocken in Chemnitz has been equipped with TIKANA® restoration glass from SCHOTT as part of its conversion into a museum. The glass has been specially developed for buildings of the Classical Modernism and the Bauhaus style and has the typical fine waviness of window glass from when the department store was first built around 1930. In addition, it is very transparent, reproduces colors accurately and is therefore ideal for museum windows. TIKANA® was used here as the outer pane in the insulating glass, among other things as a 6 mm thick glass with a solar protection coating. For the vertical stairway glazing, sandblast matting was performed on TIKANA®.

RESTOVER®: for buildings around 1900

SCHOTT developed its restoration glass RESTOVER® for the construction period around 1900. Due to its wavy surface, it resembles the window glass from this period. The windows of the German Historical Museum in Berlin were glazed with this product, for example. These are special climate windows. The thinness of RESTOVER® allows for easy installation in historical window frames and profiles. RESTOVER® light is a version with a slight texture, while RESTOVER® plus is more structured.

GOETHEGLAS: made for buildings from the 18th and 19th centuries

For reasons of historic prevention, machine-drawn glasses were also used in the historical part of the music center Bochum. SCHOTT GOETHEGLAS was processed into laminated glass with special sound insulation properties and is used in double glazing. The colorless restoration glass exhibits the characteristic, irregular surface from the 18th and 19th centuries. It is also suited for outdoor protection glazing to prevent environmental and climatic damage of valuable stained glass, for instance.
