A fire door is a kind of enclosure or a door which is used a fire protection device within homes and offices to thwart the spread of fire. Fire doors are made of a combination of materials like gypsum, steel and vermiculite boards. In fact if one has a fireplace, then it is recommended to invest in a glass fireplace door.

Fire doors are instrumental in acting as a barrier between your home and chimney. Glass fireplace doors can withstand a good amount of heat. Some fire doors have internal windows which may include a wire mesh glass or liquid sodium silicate fills between two window panes to work well and provide a formidable resistance against fire outbreak. While the wired glass can resist fire, the sodium silicate liquid acts to diminish the spread of heat. Ceramic glass fire doors are highly heat resistant and more on the expensive side compared to tempered glass.
