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 OKNA Windows & Doors can highlight
the architectural style that speaks to you.
GBG grids 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. |
