Hardware

To create a style and finish that reflects your unique taste, our hardware is designed to harmonize with our different window styles and decor ideas. 

Grids

GBG grilles consist of aluminum bars sealed in the insulation 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. 

Permanent interior and exterior grid with spacer will provide a truly authentic look. Interior grids are available in Euro-White or wood laminates to match your home's decor. External grids are available in Euro-White or colors to match product exterior.

Grid Patterns
