The range of chimney cowls that Richard Williams have in stock have been designed and engineered to solve all chimney problems. The range includes variations of static cowls, revolving cowls and bird guards.
One of the more popular cowls is the Colt Top, which works on the same principle as a Colt Cowl, but is more efficient as it’s rounded shape creates lift whichever direction the wind is blowing, eliminating downdraught. Rain drains help divert water outside the chimney pot. Colt Tops are available in Gas and All Purpose.
Many of our cowls meet the relevant British Standard (in most cases BSEN 1856-1:2003) or have been tested to stringent requirements by the manufacturer.
