Overview
The elegant, beveled profile of our 800 Series will enhance the beauty of your home's exterior by giving it the traditional look and feel of wood windows with the performance and ease of maintenance you can only get with vinyl. The 800 Series can also be painted to match any exterior.
The 800 Series offers hardware options reminiscent of classic wood windows. It is the only vinyl window we manufacture without an integrated lift rail. The slider features a handle style based on traditional wood windows.
Exterior Options

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.
