According to Florida Building Code, hurrican resistant widnows and doors should be strictly to following strictly requirements:
- Exterior side-hinged doors are be labeled as conforming to AAMAJWDMAJCSA l 0 II l.S.2/A440 or comply with Section R612.5.
2. Exterior windows and doors shall be labeled with a permanent label, marking, or etching providing traceability to the manufacturer and product.
3. The following shall also be required either on a permanent label or on a temporary supplemental label applied by the manufacturer: information identifying the manufacturer, the product model/series number, positive and negative design pressure rating, product maximum size, glazing thickness, impact-resistance rating if applicable.
4. Florida Product Approval number or Miami-Dade Product Approval number, applicable test standard(s), and approved product certification agency, testing laboratory, evaluation entity or Miami-Dade Product Approval.
5. The labels are limited to one design pressure rating per reference standard.
6. The temporary supplemental label shall remain on the window or door until final approval by the building official.
Exceptions:
- Door assemblies installed in nonhabitable areas where the door assembly and area are designed to accept water infiltration need not be tested for water infiltration.
- Door assemblies installed where the overhang (OH) ratio is equal to or more than I need not be tested for water infiltration. The overhang ratio shall be calculated by the following equation: OH ratio = OH Length/OH Height Where: OH length = The horizontal measure of how far an overhang over a door projects out from the door surface.
- OH height = The vertical measure of the distance from the door sill to the bottom of the overhang over a door.
- Pass-through windows for serving from a singlefamily kitchen, where protected by a roof overhang of 5 feet (1.5 m) or more shall be exempted from the requirements of the water infiltration test.
