Invisi-Maxx: screens tested against cyclone debris
Invisi-Maxx is the screen in the Invisi-Gard range that's built and tested to stop flying debris in a cyclone. You keep the light, the breeze and the view, all year round. Townsville is in cyclone region C.
- Independently lab tested
- 316 marine-grade stainless steel
- 15-year warranty
Faster debris than the standard asks for
In a cyclone, everyday objects become flying debris. Australian Standards set how fast that debris is fired at a screen in testing. For a home in the most extreme cyclone areas (region D), that's 35.2 metres per second.
Invisi-Maxx has been independently tested to exceed the requirements for cyclone regions C and D.
From Alspec, the Australian company that designs Invisi-Maxx. Speeds are from independent testing by an accredited lab. Ratings depend on the right mesh for the building and correct installation, so for new builds, check with your certifier. We can supply the test certificate.
44 m/s is about 158 km/h.
