Abstract: Glazings including first and second channel-section glazing elements are described. The first and second channel-section glazing elements are arranged to define a cavity in which an inner glazing element made of plastic is located. The inner glazing element includes a central portion and first and second edge portions running along opposite sides of the central portion. The first edge portion of the inner glazing element includes a first connection portion in mechanical communication with a first flange of the first channel-section glazing element. The first connection portion is integrally formed with the central portion of the inner glazing element. In preferred embodiments the second edge portion of the inner glazing also includes a second connection portion that is preferably integrally formed with the central portion of the inner glazing element.

Abstract: Glazings comprising first and second channel-section glazing elements are described. The first and second channel-section glazing elements are arranged to define a cavity in which is located an inner glazing element comprising a glass glazing element, in particular a soda-lime-silica glass sheet, channel-section glazing element or sheet of rolled glass having at least one fire polished edge. The inner glazing element divides the cavity into at least two spaces to improve the thermal and/or noise performance of the glazing. By using low emissivity coatings on one or more major surfaces of one or more of the glazing elements, the thermal performance may be further improved. Mechanical performance may be modified by the particular type of inner glazing element used. It is possible to retrofit existing glazings to improve the thermal and/or noise performance thereof.
