Triple Pane Glass
The triple pane glass used in the door is specifically designed to minimize heat transfer between the indoors and outdoors, which helps keep the interior of the building at a comfortable temperature, regardless of the weather outside. The glass is also treated with low-e coatings, which reflect heat back into the room, further reducing energy costs.
