What is the best glass to use in colder climates?
In colder climates, most regions get the best performance from a window with a higher shading coefficient or higher solar heat gain coefficient. This permits a higher amount of heat from the sun to enter the building structure, reducing heating costs. Glass with a higher insulating (U or R) value is preferred in areas where average temperatures tend to be lower. Consult with your window manufacturer or with our technical services department to help you select a glazing package that fits your location, application, and design options.
