What are the different types of chimneys?
Basically there are (3) categories of chimneys. There are the masonry chimneys which are made of brick, concrete and mortar. There is the prefab which is manufactured at a factory and is installed as a unit. There are several kinds of prefab (pre-fabricated) which include the Isokern which can be made to look like a masonry chimney. Then there is the hybrid chimney which has a masonry base, firebox and smoke chamber but it then transforms into a high temperature pipe with a steel stud frame. This last system is what the majority of repairs made in Los Angeles consist of.
