Wild birds will often nest in chimneys or, in some cases, accidentally fall into a chimney. This can quickly result in a blockage forming and gases building up in your home. Besides creating a smelly living space, this could result in carbon monoxide poisoning.
A bird guard is a cost-effective way to prevent wild birds from entering your open chimney. Ensuring gas can escape freely and your fire has a good draw throughout the year.
Besides preventing wild birds from nesting or falling in your chimney, some bird guards also increase the efficiency of your fire. They achieve this in a similar way to a traditional chimney cowl, which prevents strong winds from entering your chimney.
