Why Onduline® Roofing in the Face of Typhoons and Hurricanes?

To understand Onduline®'s wind resistance, we need to dissect its unique features:

• A fixation system with a washer of at least 16 mm, surpassing industry standards.
• A minimum of 10 fixations per m2, ensuring a robust connection to the structure.
• Corrugated sheets that enhance rigidity and stability.
• Flexibility and resilience that enable the sheets to absorb shocks and vibrations caused by gusty winds.
• Matching accessories meticulously designed to obstruct wind passage through the sheets.

As a result of these features, Onduline® CLASSIC sheets showcase remarkable resistance to high winds, up to 225 km/h when installed on a metal structure and up to 260 km/h on wooden purlins. The Onduvilla® variant takes wind resistance to greater heights, withstanding up to 315 km/h on a metal structure and up to 290 km/h on wooden purlins.

Onduline® CLASSIC roofing sheets are not just resistant; they justify very strong resistance, making them an intelligent choice for coastal areas, regions prone to typhoons, and locations where buildings face heightened exposure to the elements.

Onduvilla®, with its higher resistance, attributed to the number of fixations, further solidifies Onduline®'s reputation as a top-tier choice in the face of extreme winds. It's a testament to Onduline®'s commitment to reliability under challenging conditions.

The Belgian Building Research Institute conducted wind uplift tests on Onduline® sheets, providing scientific data on their performance under different conditions. The results are impressive:

• ONDULINE® CLASSIC on Metal Purlin: 3000Pa (225 km/h)
• ONDULINE® CLASSIC on Wood Purlin: 4000Pa (260 km/h)
• ONDUVILLA® on Metal Purlin: 6000Pa (315 km/h)
• ONDUVILLA® on Wood Purlin: 5000Pa (290 km/h)

These results, obtained with universal screws, validate the wind resistance claims for the tested configurations.

While there's a lack of specific scientific tests on typhoon resistance, Onduline® has proven its reliability globally. In Siargao, Philippines, battered by the strong winds of typhoon Odette, Onduline® emerged as the preferred choice for rebuilding over traditional metal roofs.

Siargao locals commend Onduline's superiority, praising features like lightweight sheets, easy transportation and installation, and excellent sound absorbing. The real-world resilience of Onduline shines through in extreme conditions, making it a practical and reliable solution for areas prone to severe weather.

In regions prone to cyclones, hurricanes, or typhoons, it's crucial to construct buildings capable of safely resisting the strongest winds. The UK Meteorological Office highlights the proportional increase in wind forces concerning the square of wind speed, emphasizing the need for sturdy constructions in these areas.

Onduline's resilience is exemplified by real-world scenarios, including the aftermath of Typhoon Odette in Siargao, Philippines, where Onduline sheets withstood winds of at least 240 km/h. The testimonials and video footage showcase Onduline's ability to weather storms and high winds, instilling confidence in its suitability for diverse weather conditions.

Choosing Onduline® for your roofing needs isn't just a practical decision; it's a commitment to enduring strength against the forces of nature. Backed by scientific tests, real-world testimonials, and a unique fixation system, Onduline® stands tall as a reliable choice in wind-resistant roofing solutions. If Onduline® sheets have weathered a typhoon, rest assured they can withstand local storms and high winds. Elevate your roofing standards with Onduline® and fortify your structure against the unpredictable forces of the wind.
