EnerLux offers grilles that are located between the glass and simulated divided lights. Grilles between the glass help create a traditional design while being easy to maintain and clean. Simulated divided lights feature an exterior grill made of painted anondized aluminum and an interior grill made of painted wood. Simulated divided lights provide a more authentic look than grilles between the glass but cost about $150 more per window. In addition to the standard grille patterns below, custom grille patterns are available.
