Whether you are upgrading an existing flue system or installing a new one, the Antiwind Top Terminal offers unrivalled protection against high winds and adverse weather conditions.
Understanding the Technology
This product is designed specifically to cap and protect the top of your flue system. The anti-wind technology integrated into its design ensures that your system remains efficient even when subjected to heavy gusts. Durability is at the heart of this product, thanks to its construction from premium 316L stainless steel, which provides exceptional resistance to corrosion and wear. The terminal’s robust build promises longevity, thereby reducing the need for frequent replacements and maintenance.
Key Features and Benefits

- CE Marking and Compliance: With its CE marking, the Antiwind Top Terminal meets all necessary safety and quality standards. This offers peace of mind to homeowners and professionals alike, ensuring that every installation is both safe and reliable.
- Ease of Installation: The design includes a user-friendly push-fit jointing system paired with a locking band, simplifying the installation process. In P1 and H1 installations, jointing gaskets are required at every connection to ensure superior sealing and performance.
- Versatility in Application: Whether installed on boilers, ovens, or as part of a chimney shaft liner, the terminal is adaptable to a wide range of applications. This versatility makes it a superb choice for both residential and commercial settings.
Addressing Common Concerns
One of the most frequently asked questions is about the installation process. Many customers worry about the technicalities of fitting a flue system component. Rest assured, the Antiwind Top Terminal is designed for straightforward installation. The push-fit mechanism and the clear requirement for a 50mm clearance from combustible materials are outlined in detail in our installation guide. Installation is further aided by the availability of optional accessories that complement the system perfectly.
Another common concern is related to product longevity and maintenance. Thanks to the high-quality stainless steel used, this terminal is engineered to provide long-term durability with minimal upkeep. Regular checks and maintenance are recommended to ensure that all seals and joints remain in perfect condition; however, the robust nature of the product means that these are seldom necessary.
Optional Accessories
To optimise the performance and fit of your flue system, we offer a range of optional accessories. These include additional sealing kits, flashing systems, and maintenance tools that are designed to work seamlessly with the Antiwind Top Terminal.

Installation Best Practices
For a successful installation, it is crucial to follow the recommended guidelines. Firstly, a 50mm clearance from any combustible materials must be maintained at all times. Secondly, while the product is designed for a quick push-fit installation, using jointing gaskets in P1 and H1 setups is essential to avoid any leakage or performance issues. Reviewing the installation instructions thoroughly will help achieve a secure and efficient fit. Additionally, consulting with a professional installer is advisable if you encounter any uncertainties during the process.
