Do You Know The Local Building Code Requirements?
Know The Code
The latest building code and permitting requirements state most of the Gulf Coast counties in Alabama and Florida, fall under the “Wind Borne Debris Zone.” In Florida, the law states that if more than 25% of the total glazed area of the home is replaced, the openings must have “Large Missile Level D” impact rated protection for each opening involved. “Openings” are defined as doors and window. “Protection” is defined as either impact windows or hurricane rated shutters. There are some local building departments that will permit the use of plywood if it conforms to the accepted state standards (precut panels with labels, designated plywood thickness and preinstalled mounting hardware that includes a certain fastener size, wall structure embedment and spacing.
In Mobile and Baldwin counties in Alabama, all openings must be protected in Mobile, Gulf Shores, Orange Beach, Foley and Fairhope. In other parts of Baldwin and Mobile counties, the code varies for each municipality. Check with a Folkers’ expert on local code requirements.
In addition, the state of Florida has recently implemented new energy efficiency requirements for windows and doors that are much more stringent than previous code editions. All window and/or door replacements must meet a solar heat gain coefficient (SGHC) of 0.25 or less and a U-value of 0.40 or less windows. See below for definitions.
Many aluminum framed replacement windows do not meet the new energy codes whereas Folkers’ vinyl windows do.

Terms You May Want To Understand
Design Pressure Rating is a term used to identify the structural capacity of a window and/or door system. Essentially Design Pressure represents the wind load the window or door system can withstand. Florida building codes are the most stringent in the country and Folkers products are designed to withstand the high Design Pressure requirements. Florida building codes require a minimum design load and that minimum design will vary with your location, proximity to the coast and whether you are located in a high velocity hurricane zone.
In Alabama, Design Pressure requirements vary by municipality. In Dauphin Island, Gulf Shores and Orange Beach design pressure rules mirror Florida’s code requirements. As one moves north away from the coast, Design Pressures requirements change with the distance one moves away from the coast.
