Cyclone and Storm Safety
Tractile roof tiles fitted on our interlocking battens are rated for wind speeds of 300 kilometre per hour. To put that into context, a Category 5 cyclone has wind speeds of 280km/hr.
As a comparison, both traditional concrete roof tiles and metal sheeting are rated for 225km/hr winds only after modified installations.
Tractile roof tiles are rated for impacts of up to 100 Joules. A 100 Joules impact is equal to being hit with a 68 millimetre hailstones (a tennis ball has a diameter of 67mm), or hitting the tile with a 1 kilogram hammer at 14 meter per second (normal speed for a 1 kg hammer to hit objects is 8 to 12 m/s).
In contrast, a 100 Joule impact will break traditional roof tiles and deform steel roofing sheets.
Tractile has a BAL-40 fire rating. After direct flame zone (BAL-FZ) rating, the BAL‐40 rating is the next highest assessed level. A BAL‐40 rating for Tractile means no embers can penetrate the roof and the roof can withstand heat radiance of 40kW per square metre.
The Tractile roof is Interlocked with our unique mounting system. This systems makes its very hard for pests (both the human and non-human variety) to penetrate the roof via the roof tiles.
