It is imperative to protect the chimney from the harsh forces of weather so as to increase its durability—two of its protective features are the chimney crown as well chimney chase covers. Both serve to protect the chimney from moisture and debris.
A chimney crown is generally a concrete or mortar structure placed on masonry chimneys and chimney chase covers are a metallic one that are mostly fitted on prefabricated/factory-built chimneys. Familiarity with these two components allows proper installation and maintenance, and these may impact the health of your chimney in the long run.
What Is a Chimney Crown?
A chimney crown is usually a concrete or mortar structure placed at the top of a masonry chimney to offer a shield against weather conditions. It closes any opening at the top of the chimney structure to allow rain, snow, and any debris to penetrate and cause harm. The crown is inclined to the outer side to drain water and keep it away from the flue and chimney—to avoid any water deterioration in future.
Procedure for Putting Up a Chimney Crown
The installation of a chimney crown typically requires the following steps:
a. Preparation
First, the chimney must be clean and free of debris at the top before installation.
b. Forming the Crown
With specialized molding, the chimney crown is able to direct water away.
c. Pouring the Material
Concrete or mortar, which is used to fill the mold in constructing the crown, is poured.
d. Finishing Touches
After the material is laid, it is leveled and trimmed, with the slope for water taken into consideration.
Because the chimney crowns are made from very strong materials, they are very long lasting and are built to last for many years without requiring replacement.
What Is a Chimney Chase Cover?
Chimney chase covers are components that are usually placed on homes to cover the chimney.
While the other kinds of chimney caps are meant for masonry chimneys, a chimney chase cover is installed on prefabricated or factory-built chimneys, typically, metal ones. This cover closes the top of the chimney chase – an exterior structure that surrounds the flue pipes. It is commonly fabricated from stainless steel, galvanized steel, and copper.
Chimney Chase Cover Installation Process
The installation of a chimney chase cover includes:
a. Measurement
The size of the area known as the chimney chase is correctly measured to guarantee that the cover offered fits perfectly.
b. Attachment
It’s often fastened and tightened with screws or fasteners on the upper part of the chase structure.
c. Ensuring Proper Seals
Proper sealing is also essential, to ensure that there is no seepage around the chimney cracks or penetration into the chimney system.
Conclusion
Chimney crowns and chimney chase covers are necessary accessories for chimneys since they keep water away from them; nonetheless, they differ in the manner they are placed, and materials used in making them. You should follow the correct guidelines and rules in the installation process and follow a few important rules throughout the proper usage of the chimney, whether it is masonry or prefabricated.
