Most chimneys are fabricated in following two types:

  • Masonry fireplaces
  • Prefabricated fireplaces

This article lists the different varieties of chimneys along with the different caps used with these chimneys.

Masonry Chimneys:

Whenever you hear the term “fireplace” or “chimney”, a masonry fireplace is the first picture popping into your mind. Their basic building blocks are stones or bricks along with mortar. They have a pleasant appearance and can be taken care for easily. Their construction is done on-site and is commonly seen in many houses. The firebox of masonry chimneys is made up of yellowish firebrick, and above roof section is of red brick.

Masonry chimneys are heavy. Their weight lies in the range of 6 to 7 tonnes. Owing to their heavy weight, they need wide footings to support them. If such footings are not provided to the chimneys, the fireplaces can undergo shift and crash resulting in dreadful situations. In such a situation, the flames could start coming to your house instead of going out. It is advisable to check your chimney periodically even if it has been provided with proper footing. Chimney cleaning is the task that we can’t avoid. For this purpose, hire chimney sweep Seattle and also masonry repair is followed from time to time.

Prefabricated Chimneys:

Prefabricated chimneys first arose to the picture in 1980’s. They are manufactured in factories. Prefabricated fireplaces have metal chimneys along with metal fireboxes which are very light in weight. Firebox is manufactured of cast refractory panels. Fireplace and chimneys are built independently, but they both are engineered to work dependently. These chimneys are a little difficult to install. They are installed according to the proper specifications provided to the installer of the Chimney. There should be a proper distance between wood and chimney so that wood won’t catch fire. They get damaged even by a very small chimney fire. Therefore regular cleaning is required for proper functioning of chimneys without any disaster.
