With all four panels being glass, the exquisite Strasbourgh 365 provides uninterrupted, panoramic views of the combustion chamber, so you can enjoy the beauty of the fire from wherever you are in the room plus more sides means more space to huddle around the fireplace and thaw out while watching the flames dance and flicker. This fireplace also has the option of connecting to external air and drawing air from outside instead from within the room. This means that the burning wood does not deplete the oxygen in the room and require a window to be kept open in order to keep the space sufficiently oxygenated. The Strasbourgh 4 Glass fireplaces are imported from Europe and boast a strict CE certification. The Strasbourgh 4 Glass fireplace comes with a 5-year warranty.
