Lanai Doors™ Bi-fold Systems - Miami-Dade and ASTM Hurricane Requirements and Testing

Hurricane and wind-borne debris region building codes are a growing trend across the United States. With the incredible devastation caused by hurricanes and cyclones in wind-borne debris regions, greater emphasis has been placed on products that better protect life and property. Arguably, Miami-Dade County is the gold standard for hurricane product testing.

States up and down the East Coast, the Gulf of Mexico, and Hawaiian Islands have implemented building codes (i.e. Florida Building Code and International Building Code) requiring the use of hurricane certified products. The Florida Building Code High Velocity Hurricane Zone (HVHZ) provisions apply to both Miami-Dade and Broward Counties, Florida. The non-HVHZ provisions apply to the rest of Florida. Most other states have implemented the International Building Codes which require hurricane products for wind-borne debris regions. In addition, Caribbean Island builders are requiring stronger impact resistant products with Miami-Dade hurricane certification.

Not all states and jurisdictions follow the same building code or the same version of the code. It is the responsibility of architects, builders, contractors and homeowners to determine what is necessary for your project and pre-verify that Lanai Doors™ hurricane rated systems are allowable products for your jurisdiction. States and counties have maps, similar to the State of Florida, depicting wind speeds for wind-borne debris regions. Official wind speeds are determined and periodically adjusted by the American Society of Civil Engineers (ASCE).

If you feel limited by the dimensions of any space in your home or business, give Lanai Doors or Windows an opportunity to create an entirely new experience. Lanai bifold sliding door systems can open up cramped-seating spaces and make them alive with light - creating a relaxing and uplifting ambiance in any room.

Each shipment will include a labeled frame (labeled if more than one system is shipped), individually labeled panels, and installation instructions. The bi-fold system frames are shipped broken down. A parts box will include installation instructions and assembly screws so that you can easily assemble the frame. The frame header will already include the top pivot and carriers. The threshold will already include the bottom pivots.
