...Do you need insulated glass?
Homeowners know of insulated glass as argon gas sealed between two panes of glass to prevent heat loss from your home. In the garage door industry, insulated glass is two panes with air between them to create that same effect. Manufacturers of garage doors do not use argon, as the constant movement of the doors, would cause the argon to leak and become ineffective quite quickly. If your garage is not insulated, and you do not have any appliances that create heat such as a fridge or dryer, you most likely do not need insulated glass.
