Chimney cap installation tips

To prevent rain, small animals moisture and other things from entering the chimney, you must install a chimney cap. It is a process fairly easy to complete.

Cap measurements

Make sure you take the right measurements needed to purchase the proper chimney cap.rclma Measure the length and width of the chimney if it is square. Measure the inner and outer diameter of the chimney if your chimney is round. Also, measure the tallest flue.

Cap type

Make sure you choose the right type of chimney cap. Galvanized chimney caps shouldn’t be used for gas logs because corrosive exhaust can damage the house. Also, to avoid rust, frequent maintenance is needed. More costly but easier to maintain caps are made of copper and stainless steel.

Cap security

Strong winds can blow the cap off a chimney, if it is loosely installed, and damage the surroundings. Make sure you stay away from slide-on caps. Caps that are secured using screws or flue are more durable and safe.

Cap draft issues

Evaluate the draft of your chimney before buying a chimney cap, because the cap can sometimes affect the chimney draft instead of increasing its efficiency. You can also think about buying a wind driven cap, that increases draft efficiency through a vacuum in the flue.

Cap damper mechanism

A chimney damper insulates the home, and prevents energy loss. The chimney cap should have its own damper to protect the home more efficiently.

Use all these tips to choose the right chimney cap.
