Introduction
                   Came comes in two forms –
                   “H” channel and “U” channel.
 How Glass is      These names come from the

                   type of came.

Physics of Glass   The “H” channel is used to
                   connect interior pieces of
                   glass while the “U” channel is
Types of Glass     used to finish the exterior

                   used as well.
