The Brewer Birdguard is designed to prevent birds and debris from entering your chimney. It achieves this with the use of a wired mesh designed to prevent unwanted entry into your system whilst also allowing smoke and fumes to be exhausted efficiently. Fitted with an integral rain hat, it has the added advantage of minimising rain entry helping to prevent internal structural decay. Available in either aluminium or stainless steel for greater longevity, the Brewer birdguard has deservedly become one of our most popular units over the years.
