• Chateau cowls are designed to provide weatherproofing protection to cover external wall penetrations for extract ventilation systems. 
• Weatherproof cowls are designed for use in New Zealand locations with typical weather conditions.
• Ideal for typical NZ through wall extraction ventilation applications.
• Designed and tested (by certified third party accelerated weathering) specifically for the high UV New Zealand climate. 

Suitable for any residential properties including but not limited to: 

• Standalone homes
• Terraced homes

Installed extraction ventilation system performance is always influenced by duct length and layout, as well as the accessories fitted. So, it is important to consider these when selecting the extract fan type and size.

See the linked test results summary for a more detailed explanation of the UV testing, and how Chateau compares to other weatherproof cowls. 

Reducers are available for alternative ducting sizes.
