Glazing Options

Choosing the right type of glass configuration can be confusing. We’re here to help you. Below is a short description of Sealed Units and their corresponding R-Values.

Sealed units, in their most basic form, have been around since the 1800’s. The first sealed unit consisted of two panes of glass ‘sealed’ together with a wooden spacer bar and filled with air. Since then, sealed unit technology has improved in many different ways. The first is the introduction of more durable spacer bars. The second is the introduction of a third pane of glass to the sealed unit. And the last is the introduction of argon gas fill and low E coating in between the panes of glass. With these improvements, the R-Value was developed to help measure the insulating factor. The higher the R-Value, the less heat is transferred out of your home in the winter, while also keeping the heat out in the summer. Poorly insulated windows lead to uncomfortable living spaces, condensation build up, and higher energy bills. The opposite then is true of well insulated windows. Below are the sealed unit configurations available and their corresponding R-Values.
