Common Chimney Terminations
Two chimney terminations are offered by Isokern, the DM
large crown cap and the DM small crown caps. These are cement crown
caps designed to provide a weather cap to the DM chimney system.
Their design is typical of the cement caps found on traditional masonry
chimneys.
Due to owner preference and architectural design criteria other
chimney terminations can be used alone or in conjunction with the
crown caps. Special design caps may be designed and constructed by
others and must be fashioned so as not to restrict the ow of smoke and
gasses out the top of the ue opening. Figure 71 depicts some common
chimney terminations.
Check with local building codes to establish the need for
chimney caps and spark arrestors or for any limitations to their design
and use.
