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.
