NightFlame Black Tinted Heat-Resistant Glass 4 mm Thick
Thanks to its special semi-transparent black tint, ROBAX® NightFlame glass lets the light of the flames shine through while the fire is burning, but darkens once the fire goes out to conceal the combustion chamber.
Your fireplace thus maintains a clean and elegant appearance, even outside the heating season.
