Spinner Anti Down Draught Chimney Cowl Terracotta 8/9" UK

The main purpose of the Terracotta Spinner Anti Down Draught Chimney Cowl is to prevent the penetration of the chimney by moderate or severe winds which causes smoke to escape from the open fireplace or stove or any other appliance.

Thanks to ‘sail’ design blade fins the Terracotta Spinner Anti Down Draught Chimney Cowl responds to wind coming from any direction

Its response is immediate because of its double bearing pivot action.  The more severe the wind – the more effective the Terracotta Spinner cowl becomes.

When revolving, the Terracotta Spinner Anti Down Draught Chimney Cowl also ventilates the chimney shaft helping keep it dry and it can also help prevent back up smells coming down into the room via the fireplace or stove.

Does not impede the performance of the chimney in any way.

Suitable for use with all fuels - oil, gas & solid fuels (except anthracite)

The Terracotta Spinner Anti Down Draught Chimney Cowl also protects the chimney from moisture ingress and nesting birds. If your problem is excess moisture ingress a Static Anti Down Draught Chimney Cowl offers more protection from driving rain than either the Spinner Anti Down Draught Chimney Cowl or Anti Bird / Anti Rain Chimney Cowl

Chimney Cowls are also known as Chimney Pots, Chimney Hoods or Chimney Caps. There are various names for these products but they are originally called Cowls.

What the Terracotta Spinner Anti Down Draught Chimney Cowl will not do:

Should not be used with Anthracite fuel or fuels high in sulphuric acid.

The Terracotta Spinner Anti Down Draught Chimney Cowl must not be used on a chimney shorter than 18 feet 

Will not prevent a down draught if the chimney is more than 4 feet lower than the apex of the roof or 4 feet lower and in proximity to a taller structure, hedge, or tree(s)

This cowl will not prevent a draughting problem when there is no wind – if the problem still exists when there is no wind (in conditions such as cold, calm and frost) the problem is a lack of draught (not a downdraught) and a motorised chimney cowl is required such as the Super C Electric Fan Cowl No anti down draught chimney cowl can solve a lack of draught.
