Glazing Bars, Mullions, Transoms

For window manufacturing until the early 20th century it was economically beneficial to use smaller panes of glass, which were much more affordable to produce. These were fabricated into a “Grid” (in diagonal or other shapes called “Lattice) to manufacture large windows and doors.

With increasing technical capabilities, larger glazing panes could be manufactured more efficiently, however many consider the division of a window or glazed door into smaller panes to be more architecturally attractive and suitable for a variety of design approaches. In the UK, Australia and many other countries these Mutins are nowadays called “Glazing Bars”, “Window Bars”, “Colonial Bars” or “Sash Bars”.

Mutins should not be confused with “Mullions”. Mullions separate two compete window elements, normally being vertical structural (sometimes design) elements, supporting an arch or lintel above the window. When supporting another glazing element they are connected to a horizontal structural element called “Transom”.

Sustainable Construction Services can supply you with a huge variety of glazing bars, mullions, transoms in any shape (profile type) and dimensions to serve different design approaches in a variety of window types.

It is further your choice, which material you prefer. Usually, Glazing Bars are supplied in the same material than the window, i.e. uPVC, timber or aluminium, however SCS can also supply specialised materials, for example lead. Lead grids or lattices for windows have been very common in Australia.
