Chimney Side Baffle

A 'smoke over' issue happens when smoke exits one flue and is immediately sucked into an adjacent, inactive flue, causing smoke to backdraft into other rooms. This side baffle acts as a physical barrier between flues, forcing the smoke to exit upward and away from neighboring openings.

This 8x20-inch side baffle is designed to be compatible with both standard Stainless Steel and Black chimney caps. Because it is a universal-style component, it integrates easily into most multi-flue setups, but you should measure your flue spacing to ensure the 8x20 dimensions provide adequate coverage.

Yes, stainless steel is the industry standard for chimney components because it resists corrosion from the acidic byproducts of combustion and withstands high temperatures without warping. It ensures the baffle remains durable and effective over many heating seasons.

Not necessarily. You typically only need to install a side baffle if you are experiencing cross-contamination of smoke between flues. If you have multiple flues but they are spaced far enough apart that smoke doesn't travel between them, you may not require one.

If you are comfortable working on your roof and have experience with basic chimney cap maintenance, this is a manageable DIY installation. However, if you are unsure about accessing your chimney or securing the baffle properly, it is safer to hire a certified chimney sweep to ensure it is installed securely.
