Single Flue Chimney Caps
Choice of Metals
Browse our huge selection of single flue chimney caps for square or rectangular
clay flue tiles. You'll find chimney caps in stainless steel and copper—all with lifetime warrantees. Stainless steel is the best choice for the money, but copper is
much more beautiful. It's a must for upscale homes, historic homes, and homes with other copper features like rain gutters or flashing.
One of our most popular models, the Clamp Cap, comes in plain stainless steel
and your choice of a black or dark brown powder coat finish. The powder coating is baked on for long-lasting beauty.
There are inexpensive galvanized steel chimney caps that work well in especially
dry climates like America's southwest. There are even aluminum chimney caps in several sizes. Be aware, though, that aluminum should not be used with oil burners or with wood
stoves that are the home's primary source of heat.
When you click on one of our single flue chimney caps, you'll notice that it
adjusts to fit a range of flue sizes, like 6 1/2" by 11" to 9" by 13 1/2". This range means the chimney cap will fit flues with outside dimensions as small as 6 1/2" by 11"
and as large as 9" by 13 1/2". If your flue does not fit into a size range, we can have a chimney cap custom made for you.
Single flue chimney caps are the easiest type to install. All models fit
over your chimney flue and attach by tightening a few screws. 'Clamp caps' in stainless steel or copper install by turning just one screw that tightens a band around the flue.
Ideal for do-it-yourselfers, these give you an easy and inexpensive way to keep rain and critters out of your chimney.
While the chimney caps on this page are all built with 3/4" mesh, most are
available by special order for customers in California or other wildfire-prone parts of the country. Please see also the California chimney cap page of our website.
Chimney Caps for Problem Fireplaces
Smoke escapes from fireplaces into the room for a variety of reasons. We
offer chimney caps to correct these "back-puffing" problems:
- VacuStack chimney caps correct back-puffing problems caused by wind.
If your fireplace smokes on windy days only, a VacuStack can make it stop. As wind passes through the top of the Vacu-Stack it creates a vacuum over the flue, literally pulling
the smoke up the chimney.
- Flue stretchers correct back-puffing caused by flues that are not tall
enough or by smoke from one flue entering an adjacent flue. Flue stretchers come in stainless steel or copper, in 22" and 34" heights. Custom sizes are available by
- Enervex chimney fans will cure any and all types of back-puffing
problems. Formerly called Exhausto fans, these Swedish-engineered fans mount on top of the flue. They can even compensate for badly designed flues.
If your fireplace is letting smoke escape into the room our friendly chimney cap
experts will be happy to help you diagnose the problem and select the right solution. Just call us at 888 834 7375 or email us at Answers@FireplaceMall.com.
When Not to Use a Single Flue Chimney Cap
Here is a list of situations for which a single flue chimney cap is not the best choice:
- Do you want a chimney cap that attaches to the crown (the concrete pad
surrounding the flue) instead of to your flue?
- Does your flue stick up above the crown less than an inch?
- Is your flue a large or unusual size?
- Do you want to protect your entire chimney crown from acid rain?
- Would placing one chimney cap over two or more individual flues be more
attractive and economical than placing individual chimney caps on each flue?
If so, a chimney cap more typically more typically used for multiple flues may work better for you. We have them in a huge range of sizes, and you attach that type of chimney cap to the crown (the concrete pad surrounding the flue) rather than to the
