    Anwendung farbneutraler Reflexionsgläser im Hochbau
    (Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft, 1978) Klein, Werner
    Mit der Entwicklung von Interferenz schichten aus hochbrechenden Metalloxiden auf großen Glasflächen gelang die Herstellung farbneutraler Reflexionsgläser für die Gebäudeverglasung. Gemessen an den Anforderungen, die besonders bei klimatisierten Gebäuden an die Verglasung gesteht werden, vereinigen farbneutrale Reflexionsgläser in sich die Vorteile eines zuverlässigen Wirkungsgrades, natürlichen Tageslichtes und umweltfreundlicher Ansicht. Witterungsbeständige Metalloxidbeläge mit guter optischer Qualität lassen sich mit einem Tauch- und Einbrennverfahren herstellen. Die vielseitigen Einsatzmöglichkeiten des veredelten Spiegelglases als Isolierglas, Fassadenplatte und Sonnenschürze werden an Hand von Anwendungsbeispielen gezeigt. Application of neutral-coloured solar-energy-reflecting glasses in building construction With the development of interference layers of highly refractive metal oxides on large glass surfaces it became possible to produce neutral-coloured reflecting glasses for the glazing of buildings. With regard to the special requirements on glazing for air-conditioned buildings, neutral-coloured reflecting glasses combine all the advantages of reliable efficiency, natural daylight and a pleasant environment. Dipping- and baking procedures result in metal oxide layers of high resistance to atmospheric conditions and excellent optical quality. Multiple applications of processed plate glasses for insulating glasses, facade panels and sun-shielding aprons are shown by examples. Application de verres réflechissants de teinte neutre dans le bâtiment Avec le développement de couches d'interférence d'oxydes métalliques d'indice de réfraction élevé sur de grandes surfaces de verre il est devenu possible de produire des verres réfléchissants de teinte neutre pour le vitrage d'immeubles. En tenant compte des exigences établies principalement pour le vitrage d'immeubles climatisés, les verres réfléchissants de teinte neutre réunissent en eux tous les avantages d'un mode de fonctionnement sûr, de la lumière de jour naturelle et d'un environnement agréable. Un procédé d'immersion et defixation fournit des revêtements d'oxydes métalliques d'excellente qualité optique et de bonne résistance aux agents atmosphériques. Les multiples applications de glaces polies traitées pour verres isolants, panneaux de façade et panneaux brise-soleil sont demonstrées à l'aide de quelques examples.

    Glazing against fire
    (Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft, 1993) Klein, Werner
    Conventional glazing materials used to be the weak spots in a building, but nowadays fire-resisting glass can help to limit the spread of fire. In a fire test glass is treated during the initial phase by a temperature difference between edge and middle of the pane which causes breakage to normal glass within 3 to 6 min. Wired glass is held in position by the wire net for a limited time. Special borosilicate glass without wire net withstands this temperature difference during the heating-up phase due to its low thermal expansion coefficient, 1/3 of normal glass, and an additional heat-strengthening process. Borosilicate glass also shows higher viscosity in comparison to float glass and wired glass, respectively, and, therefore, provides a long fire-rating time at temperatures above 1000 °C. Using special steel frames which can keep the melting glass within the frame, borosilicate glass is able to provide an integrity and stability up to 2 h. In case heat insulation is required, appropriate glass systems must be chosen. Two different systems are available: designs consisting of multiple layers of glass and intumescent interlayers and such using an aqueous gel in between two tempered glass panes. Some of the international certificates are shown as examples, followed by typical designs of construction elements. Typical applications of the non-wired glass types are shown in slides taken from fire doors, - screens and - windows providing fire ratings from 30 min in timber frames up to 2 h in special steel frames.
