1. Risk Category
Determine Your Wind Load Requirements
Wind load for a particular structure is determined by its Risk Category. Three wind speed maps are used for Risk Categories I, II and III/IV. Risk Categories are defined as follows:
Category I
Buildings and other structures that represent a low hazard to human life in the event of failure. e.g. minor storage facilities.
Category II
All buildings and other structures except those listed in Risk Categories I, III, and IV.
Category III
Buildings and other structures that represent a substantial hazard to human life in the event of failure, e.g. schools.
Category IV
Buildings and other structures designated as essential facilities, e.g. hospitals.

2. Wind Speed Requirements
Determine Minimum Wind Speed Requirements
Refer to the Wind Speed Line Maps for the Florida Building Code to determine the Minimum Wind Speed (MPH) required for your residence.
1609.3 Ultimate design wind speed.
The ultimate design wind speed, Vult, in mph, for the determination of the wind loads shall be determined by Figures 1609.3(1), 1609.3(2), 1609.3(3) and 1609.3(4). The ultimate design wind speed, Vult, for use in the design of Risk Category II buildings and structures shall be obtained from Figure 1609.3(1). The ultimate design wind speed, Vult, for use in the design of Risk Category III buildings and structures shall be obtained from Figure 1609.3(2). The ultimate design wind speed, Vult, for use in the design of Risk Category IV buildings and structures shall be obtained from Figure 1609.3(3). The ultimate design wind speed, Vult, for use in the design of Risk Category I buildings and structures shall be obtained from Figure 1609.3(4). The ultimate design wind speed, Vult, for the special wind regions indicated near mountainous terrain and near gorges shall be in accordance with local jurisdiction requirements. The ultimate design wind speeds, Vult, determined by the local jurisdiction shall be in accordance with Chapter 26 of ASCE 7. The exact location of wind speed lines shall be established by local ordinance using recognized physical landmarks such as major roads, canals, rivers and lake shores wherever possible.
3. Exposure
Exposure Categories are based on "surface roughness", defined as follows for buildings less than 30 feet high, as defined by DASMA.
Wind load for a particular structure is determined by its Risk Category. Three wind speed maps are used for Risk Categories I, II and III/IV. Risk Categories are defined as follows:
Exposure B
Urban and suburban areas, wooded areas, or other terrain with numerous closely spaced obstructions having the size of single-family dwellings or larger, prevailing for a distance greater than 1,500 feet in any direction from the installation.
Exposure C
Open terrain with scattered obstructions having heights generally less than 30 feet. (Commonly associated with flat open country and grasslands).
Exposure D
Structure close distance (typically within 600 feet) from an “open waterway” one mile or more across. *not currently available through Invicta Door

Storms generate both positive and negative pressures on a garage door. Positive pressures push the garage door inward, while negative pressures pull the garage door outward.
