Chimney caps purpose – the chimney crowns, also called caps or floats, is added to the top of the brick chimneys to prevent environmental damage in the chimney masonry. Crowns can be bought premade as an aftermarket option for the owner of the home and property. But the savvy do-it-yourselfers can do one and install it yourself for much less.
Measure across the top of the chimney caps purpose to determine the width of the stack, and then measure the width of the aperture of the fly (less ceramic stack sticks up from the interior of the chimney). Cutting square ¾ inch plywood to the measurements from the chimney, but add 2 inches in width to create a small lip that will make holding and install cement cap easier in a later step.
Wait a full 48 hours to let the cement dry completely. Unscrew the cell plates; chances are some will stick and will have to be chiseled away. Keep the lip of the crown, carry it up the ladder to the roof and place the cap over the chimney caps purpose flue threading through Small Square in the center of the crown. Seal the small gap between the flue and the crown with heat-resistant fire-rope and caulk.chimney caps purpose, purpose of chimney cap, what is the purpose of a chimney cap, mobile home chimney caps
