Before you start shopping for our fireplace doors, you will want to determine if your fireplace is a masonry or a prefabricated (prefab).
Masonry and prefab fireplaces are made out of different materials and have different safety codes. A masonry firebox is made out of brick or stone, whereas a prefab fireplace has a metal firebox with ceramic refractory panels.
It is good to note that prefab fireplace door replacements require a custom fitting door size, whereas a masonry fireplace can often use standard sizes such as small, medium, or large.
