Pella Designer Series sliding and hinged patio doors, as well as windows and transoms, feature a hinged glass panel that swings open to allow homeowners to change the integrated between-the-glass blinds and shades. The blinds and cellular shades install using the maker's snap-in/snap-out system; once installed, they operate without cords, and shades operate from the top down for privacy. Several colors are available. The included unfinished wood grilles can be removed, and the interior face can be stained or painted. Designer Series patio doors and windows offer double- and triple-pane glazing options. 888.847.3552.
