What is the IRC for exterior doors?
The IRC contains specific requirements for the wind resistance of doors. Section R609.2 of the IRC requires that exterior doors be designed to resist the wind pressures specified in IRC Table R301.2 (2). Table R301.2 (2) lists positive and negative wind pressures for components and cladding for various locations within the building. Areas near roof and wall edges and areas near corners, where turbulence creates localized high wind pressures, must be designed for higher loads. IRC Table R301.2 (2) is based on Exposure B conditions for buildings with a mean roof height of 30 feet or less. Table R301.2 (2) pressures must be multiplied by factors listed in IRC Table R301.2 (3) for different mean roof heights and exposures.
How can damage to glass doors be prevented?
Damage to glazing systems (windows) in doors can be prevented, or at least minimized, by using glazing or opening protection systems that have been designed to resist wind and windborne debris forces specified in the building code. Impact-resistant (i.e., debris-resistant) systems provide protection using laminated glass or polycarbonate glazing systems. The use of physical opening protection systems such as storm shutters or panels, fabric screens, or structural wood panels is also a common means of achieving protection for glazing. Impact-resistant doors and storm shutters and panels must be third-party tested and rated. Note that storm shutters and panels are typically not rated to reduce wind pressures on the doors they protect, so doors must always be installed to withstand wind pressures. Impact-resistant doors commonly include reinforced frames, tighter weatherstripping, and energy-efficient glass.
How to protect sliding glass doors from wind?
Protect entry doors and sliding glass doors against heat loss and gain, wind pressures and windborne debris during hurricanes, wildfires, or severe storms by installing impact-rated doors or by installing impact-rated storm shutters or panels to protect the doors.

What type of shutters are used for doors?
The primary types of storm shutters for doors are rolldown, accordion, and colonial shutters.
Why are air sealed doors important?
Insulated, air-sealed doors are an important component of an energy-efficient and durable home. Door assemblies must also be strong enough to withstand wind pressures acting on them and be fastened securely enough to transfer those wind pressures to the adjacent wall. Pressure failures of doors can allow glazing to fracture or glazing frames or supports to fail. Anchorage failures can allow the entire door to be ripped from the wall, as shown in Figure 1. Either type of failure results in the failure of the building envelope and allows wind and water to enter the building.
What is the wind pressure for windows?
AAMA/WMDA/CSA 101/I.S.2/A440 ( North American Fenestration Standard (NAFS)/Specification for windows, doors, and skylight) lists design test pressures of 15, 25, 30, and 40 psf. Doors used in areas where wind pressures are greater than 40 psf need to be tested per ASTM E330 ( Standard Test Method for Structural Performance of Exterior Windows, Doors, Skylights and Curtain Walls by Uniform Static Air Pressure Difference ). For residential construction, local officials must ensure that products proposed are adequate to resist the component and cladding loads of Table R301.2 (2). For engineered construction, the designer should specify wind pressures required for doors and should base them on component and cladding loads from either Chapter 6 of ASCE 7-05 or Chapter 16 of the IBC.
