Saint-Gobain Sekurit has been in the glass business for a very long time. So long, in fact that it was founded under the reign of Louis XIV, the Royal Mirror Glass Manufactory developed a revolutionary procedure for making mirror glass: table casting. It opened its main production site in a small village in the northeast of the kingdom, Saint-Gobain, from which it took its name.  Today Saint-Gobain Sekurit is the leading manufacturer of automotive glazing.

A porthole, sometimes called bull's-eye window or bull's-eye, is a generally circular window used on the hull of ship. The function is to permit light and fresh air to enter the dark and often damp below-deck quarters of the vessel. It also affords below-deck occupants a limited view to the outside world. 

Porthole's may also be called a sidescuttle or side scuttle (side hole), as officially termed in the International Convention for the Safety of Life at Sea. This term is used in the U.S. Code of Federal Regulations.It is also used in related rules and regulations for the construction of ships. The use of the word "sidescuttle" instead of "porthole" is meant to be broad, including any covered or uncovered hole in the side of the vessel
