Glass doors, also called “lited” doors, include panes of glass allowing light to pass through the door. Sun Mountain’s glass doors can be either interior doors or exterior doors (entry or “front” doors), and are typically made with individual lites—each pane enclosed and sealed in a mullion or muntin (called “True Divided Lite,” or TDL). Alternatively, one large pane of glass can be overlaid with a false mullion or muntin grid (called “Simulated Divided Lite,” or SDL). Doors with glass can be also combined with panels.
Sun Mountain offers over 30 standard glass styles, including many decorative styles.
