What Are Custom Windows?
Custom windows are specially made to match your home’s exact size, style, and energy performance needs. They are built based on precise measurements taken from your rough opening, ensuring a flawless fit and maximum energy efficiency.

Custom Shape Windows: All Features and Options
Double & Triple Custom Windows
Glass panes are the largest area of any window and the most vulnerable to heat loss and gain. To provide adequate thermal performance and save up your money on energy bills, a minimum of 2 panes are required. Traditional 7/8″ double glazing options are used and can accommodate 1-1/4″ for all custom windows.
In areas with a harsh climate, triple pane custom windows can be especially profitable. Ecoline triple glass packages qualify for high energy-rating standards with 1-3/8″ and 1-1/4″ options available. It can be used in combination with gas injection and/or LoE glass coatings but are not necessary.
