Mullions
Mullions are the vertical bars that divide windows or glass panels in buildings. They're like the support posts that hold up and separate different sections of glass, helping to create larger window arrangements while maintaining structural strength. You might think of them as the vertical dividers you see in large office building windows or store fronts. These important building elements can be made from various materials like aluminum, wood, or PVC, and they work together with horizontal bars (called transoms) to create window grids. Understanding mullions is crucial for roles in glazing, window installation, or architectural construction.
