The Cathedral Multi Flue Chimney Cap

Available in Copper, Lead Coated Copper, Freedom Gray, Stainless Steel, Aluminum and Steel

This multi flue chimney cap features a convex roof with decorative standing seams. It is made to size with a radius roof in the shape of 75% of the dimension on the screen side portion.
The radius of the roof changes with the size of your cap, but is as consistent on the look as possible.
Roof will feature seams as needed due to sheet stock sizing. There is no way around this.
This chimney cap be side mounted or top mounted.
Copper or aluminum screen (expanded metal) is used to allow for ventilation.
The roof is removable to allow for cleaning. This is done by removing the 4 corner bolts that mount the roof to the frame. This means the roof will normally come out in one piece. For large caps, this task may require 2 people.
As seen in images and submittal, this cap vents on 2 sides only, rather than on all 4 as more standard chimney caps. Prior to ordering, ensure this chimney cap will provide enough ventilation for your application.
This product is cut by laser to ensure a perfect fitting.
Custom designs, sizes and different materials may be available. Please contact us for pricing. Made in the USA.

Ordering Instructions

A - Please fill out the form in order. With each selection, the main image changes to reflect your choice.
B - Approximate width and Approximate length fields are used calculate the price of your chimney cap. Pick the ranges that match your dimensions.
C - For side mount configurations, please make sure to either tell us to "Add 1/4" to Length and Width" via selecting "Yes" in that field, or pre-add at least 1/4" to your exact dimensions and tell us not add another 1/4", unless necessary. Ordering the exact dimension of your chimney will result in a chimney cap too tight that will not fit without costly on site modification.
D - Please do not place an order for a chimney cap out of square. Instead, contact us for a quote. A template or sketch may be necessary.
It is mostly common to order on the square caps for small, out of square gaps, up to 0.75"-1", since most of the time chimneys are out of square. However, it is a good idea to make a template on site and test fit to make sure the chimney cap would fit.
Shims can also be used if necessary on side mount applications to avoid denting the side of the chimney cap.

Top Mount vs. Side Mount

Top Mount: A top mount chimney cap is ideally used on irregular shape chimneys, those with out of square corners or made out of stones for example. It can also be used when a cap smaller than the chimney itself is desired (which also makes it less costly), or simply if its visually preferred; when the vertical side skirt portion present on side mount caps is not a desired feature.

Side Mount: An outside mount chimney cap features a vertical mounting skirt covering part of the side of the chimney, usually around 3.5". This is the ideal way to mount a chimney cap in most instances, as it covers the whole top of the chimney, protecting it against the weather.
Side mounting is ideal in most situations if possible.

Installation

Top Mount: Typically, a top mounted cap will be attached with construction adhesive. It can also be attached via tapcons, screws or anchors, however, this is normally not desirable as it is something that would need to be waterproofed.
It can also be either soldered to an existing chase cover if present, or attached via zip screws, rivets, or even the aforementioned screws, anchors or tapcons.

Side Mount: This most common version of our caps can be mounted via screws, masonry pins, anchors or tapcons. Unlike a top mount cap, this is to be mounted from the side, through the vertical side portion of the chimney cap base (a.k.a. skirt) which can be easily drilled. It can however, also be mounted via construction adhesive, using the underside of the horizontal portion of the base like a top mount cap.
This is only typically done because its quicker/easier, or in order not to see the side mounted fastener. This method is not as common.
Although installation is considered simple and straight forward, we recommend that it be done by a professional.

Choosing the right material

Chimney Cap Material: Copper, Stainless Steel, Aluminum or Galvalume (Steel)?

Colored Materials: The first thing to consider is whether something in colors is desired. If so, that narrows choices down to either Kynar Aluminum or Kynar Galvalume (steel). Kynar-based PVDF are coatings formulated to resist sun and weather damage.

Steel (Galvalume) - Available in colors: Zinc Aluminum coated Steel for higher corrosion resistance, coatted with Kynar colors. Comes in the same colors as aluminum with a more rigid substrate, however, it is also heavier. Galvalume materials have self healing properties where cut or scratched.
Since this material is steel based, it is not an ideal choice for coastal (saltwater or brackish water) environments. For those, aluminum is the better choice.
Aluminum - Available in colors: Offering the same colors and look as Kynar coated galvalume steel at a lighter weight. Unlike galvalume, this can be used in costal environments.
Galvalume Plus (Acrylume): Zinc/Aluminum coated steel with an acrylic coating. Galvalume has a similar look to galvanized steel while being vastly more corrosion resistant. Galvalume materials also have self healing properties where cut or scratched.
Copper: Our most popular material. Copper does not rust and has antimicrobial properties. It is widely used in any environment. Copper can can be soldered or welded, which makes it a much better choice for now and future repairs. Copper comes with a raw finish that will start to patina immediately once outdoors, turning partly brown the day after the installation and mostly brown within a month. Although there's no precise way to determine due to many factors, copper will typically start to turn green within 25-35 years.
Freedom Gray: This copper based material offers all the same advantages as copper with a tin/zinc coating that will develop a mature slate gray patina after around one to three years of weather exposure.
Lead Coated Copper: Copper that has been dipped in lead. A traditional material that offers all the same advantages as copper. Because of the lack of solubility, not only lead coated copper prevents most if not all staining, it's environmentally safe.
Stainless steel: A trade off between color choices and sturdiness/longevity. While stainless steel withstands the test of time, it is limited to its mill finish (2B finish) look. The stainless steel we typically offer is a 304 alloy (most common). This alloy should not be used in coastal environments. A 316 marine alloy can be offered as a special order material.
Zinc: Special order. A traditional look at the cost of a more malleable, lighter material. While easier to work with, zinc is soft, and not always (depending on size and configuration) the best choice for a chimney cap. It can be offered as a special order in either a raw or other finishes.
