Why you can trust the expertise behind our glass
Manufacturing flat glass requires specialized industrial processes and significant expertise. At Guardian Glass, this expertise has been developed over decades of glass manufacturing and is used to produce the glass that will later be transformed into the glazing used in windows.

From our glass factory to your home
The window installed in a home is the result of work carried out by several professionals.
Guardian Glass – producing the glass
Glass manufacturing begins in float glass plants where large sheets of glass are produced. Certain products, such as Guardian Sun™ glass, have a coating applied on their surface that influences how heat and light pass through the glass.
Glass processors – assembling insulated glass
Glass processors transform large sheets of glass into insulated glass units (IGUs), commonly known as double or triple glazing.
Window manufacturers – producing the window
Window manufacturers assemble the different components of the window — including the profiles developed by system houses and the IGU — to create the complete window system.
Window dealers and installers – installation in the home
Window dealers and installers help homeowners select a suitable window and install it in the building.
One window,
several areas of expertise
Guardian Glass works with glass processors, window manufacturers and installers across Europe to highlight the role glass can play in windows and help homeowners make informed choices when replacing or selecting new windows.
