Glazing bar
Originally, only small panes of glass could be manufactured, and glazing bars served as dividers. Nowadays, glazing bars are used predominantly for aesthetic reasons.
A distinction is made between three different types:
Genuine or glass-dividing bars
This refers to a type of bar that divides the glass, so that each bar field is fitted with an individual pane. Windows made up of several small panes are rarely found these days. This method of construction closely resembles the original way of manufacturing and is therefore also very labour-intensive. In addition, heat loss is greatest with the glass-dividing bar variant. Every interruption of the pane is in direct contact with the outside of the window, and this creates a cold bridge.
Imitation or bonded-on bars
The so-called “Viennese bar” (Wiener Sprosse) is counted among the imitation glazing bars and represents the affordable alternative to genuine glazing-bar windows. This type of bar is visually indistinguishable from glass-dividing bars and is ideal for recreating slim bars. The surface-mounted bars are simply bonded onto the glass and merely sealed with silicone. For this reason, they have no effect on the insulating properties of the glazing.
This type of bar looks particularly attractive on country-style houses or restored buildings that are listed as protected monuments. They give the entire building an exceptional and historic appearance.
Internal bars
Internal bars are inserted as a bar grid inside the glazing. This eliminates the labour-intensive upkeep of the bar construction. A particular feature of bars located within the cavity between the panes is that, with triple glazing, the bar is placed in only one of the two cavities between the panes.
Today, glazing-bar windows are used predominantly in the renovation of listed buildings and, in new builds, serve more as a design feature. In doing so, they lend the window and the entire building a distinctive character.
At Fensternorm, you can choose as standard between internal bars in a width of 18 mm or 8 mm and surface-mounted bars in a width of 26 mm. Of course, we will endeavour to fulfil (almost) any other size requirement you may have.
