Common Questions

Do I Need A Chimney Cowl?

While chimney cowls are not strictly necessary, installing a chimney pot cover comes with a number of great benefits. They increase comfort levels inside the home by preventing smoke or other harmful gases from blowing back into the room, help to prevent water ingress or birds from entering the chimney space, and can help improve the performance of fires that homeowners might struggle to ignite or keep burning easily.

How Do You Fit a Chimney Cowl?

All you need to do is either use strapping, fix with bolts or sleeve the chimney cowl over the top of the chimney pot itself. The exact method you’ll use depends on the exact product you’ve bought, but most come with strapping ready to use as this is the most straightforward to install. Fitting a chimney cowl is a quick and easy process that shouldn’t cause any marks, holes or other damage to your chimney flue, whether you’re installing one for the first time or fitting a replacement.

What Sizes Are Available?

Chimney cowls come in a wide array of sizes, so make sure to measure and be sure of the size you need for your own chimney first. Standard sizes can range from 100mm to as large as 300mm – or the measurement of the internal diameter.

Do Spinning Chimney Cowls Work?

Spinning chimney cowls are a very effective option that has become more popular in recent years. They work by using the force of the wind to spin a small turbine, which increases draft. This then creates a sort of vacuum in your chimney, drawing fresh air up into the flue and blowing it outside your home. Spinning chimney cowls are ideal for homes whose chimneys experience severe downdraught or backflow.
