See-through fireplaces can look incomplete or flat without the right interior panels. Standard liners often fail to enhance both sides of the firebox, leaving the flame display underwhelming, especially in open-concept or modern spaces where visual appeal matters most. The Majestic Reflective Black Glass Panel Kit for the Echelon II See-Through Direct Vent Fireplace transforms your firebox with a bold, high-end finish. Made from durable black ceramic glass, the panels reflect light and movement to create a richer, more luxurious fire view from both sides. Make your fireplace a true centerpiece from every angle.
