What are Grids?

 

 

Grids are sometimes referred to as muntins, defined as a vertical bar in a window sash. Grids can also be known as grilles, defined as  a framework of metal bars or wire which is placed in front of a window or a piece of machinery, in order to protect it or to protect people. To sum up, grids are designed for decorative and security purposes. Grids can be placed in two different areas of a window, the area between glass, or outside of the glass. To dive in deeper, we will show you a few types:
