Are you looking for a stunning design detail to instantly set your home apart both inside and out? A choice of decorative grids for your windows & doors can highlight the architectural style that speaks to you.

Grids between glass (GBG) consist of aluminum bars sealed in the insulating airspace between the two panes of glass. Because the interior and exterior glass surfaces are not affected, cleaning your windows is a much easier task. GBG grids on two-tone windows are available with matching interior and exterior colors.

(* Insect screen cannot support significant amounts of weight. Please keep small children and pets away from windows when only insect screens are in use.) Our company offers ThruVision® Screen standard on the 500 Series to improve the view through the window while protecting the interior from insects and allowing proper ventilation.
