Hawaii is in a Hurricane Zone

Hawaii is likely to experience a direct hit from a hurricane in the near future. In the last few years, we have been very fortunate to have escaped major damage from storms and hurricanes on Oahu but it’s apparent the weather patterns are changing.  In 2015 we saw more storms and hurricanes in the Central and Eastern Pacific than had been experienced for decades prior. For the first time ever, 2016 saw two Category 1 hurricanes come within 100 miles of the islands, one causing damage on the Big Island.  In 2014 Hurricane Iselle caused $80 Million in damage.  It’s very possible and even likely that one of these hurricanes will, in the near future, directly hit us; if that happens many of the existing windows will be destroyed.  That’s why we offer so many products to help you protect your home and family against storm damage.

WinDoor Hurricane Products

WinDoor offers windows and doors with design pressures in excess of +150 / -150 which is equivalent to a wind speed of 265 miles per hour.  That’s reassuring.  WinDoor products are designed to resist impact from wind-borne debris and are an attractive alternative to exterior shutters.  When impact glass is used, even if the glass is broken, this product stays in place, sealing out high winds and water to prevent storm damage to the inside of your home. These windows and doors are specifically engineered to withstand the effects of a coastal storm or unwanted intruder.
