hurricane-resistant synthetic thatch

Curious about count Zone 4 wind speed counties in the United States? County officials declare their official wind speeds counties when they adopt local building codes generally. However, the wind speeds should reflect those stated by the recent publications from the American Society of Civil Engineers (ASCE).  Sometimes several wind speeds apply in very large cities. See, many things affect the wind speed that a particular structure must withstand. The NFPA Codes Zones and FEMA identify Zone 4 areas as areas between the 130-mph and the 150-mph isotachs.

Note: An isotach is a map line connecting points of equal wind speed.

Endureed synthetic thatch is wind rated and can tolerate extreme winds. Our products have survived Category 5 hurricanes and tornadoes. Resistant to wind up to 174 mph, Category 5 hurricane.

Incidentally, just a reminder that when you see a windstorm classification rating on roofing products, it’s talking about wind uplift pressures in pounds per square foot (psf). Here’s a link to a really handy website that lets you search by address or latitude and longitude.
