Design Pressure

Wind-Borne Debris Region

The Florida building code has wind zone specific performance requirements. A Design Pressure (DP) standard is defined for all projects located in the state. Other states are also adopting DP requirements.

Design pressure requirements can vary as they are based on product location on the building, height of the building, density of buildings, and wind zone designation. The positive DP number is the standard for wind blowing at the building (windward) and the negative DP number represents the vacuum pressure on the opposite side of the building (leeward).

All ODL doorglass products (decorative glass, clear glass, Integral blinds) with HP and HP Pro frames are certified to meet the DP requirements of the code in 1 and 2 story buildings. Transoms and bath windows have a +/- 130 DP rating and meet code requirements for fixed windows. These doorglass, transom and bath window products are not impact resistant and will require shutters in the wind-borne debris region.

Click on the desired report below. The doorglass certification must be accompanied by a current Florida state product approval or Miami-Dade County NOA for the glazed single door assembly it is being used with. Some product approvals already list ODL Doorglass. ODL doorglass assemblies are on file with NAMI.

When installing roundtop transoms, framing is critical. See installation instructions on the Florida Certification (FL 4554).

NOTE: The design pressure rating for a glazed entrance system is the lowest certified rating of the system or any component within the system. ODL doorglass meets the DP requirements of most job sites. See the certification for specific details.
