What is Design Pressure?
The Design Pressure (DP) is the pressure (measured in Pounds per Square Foot [PSF]) that a building or building component should be designed to accommodate without failure. Specifications for glazing systems will generally indicate the DP in one of three manners: 1) Offer a specific DP (flat walls, parapets and building corners will each generally have a different DP), 2) Refer to a governing Building Code for standard methods of determining the DP, or 3) Refer to a Wind Load Study performed on a scale model of the structure, that yields the DP for various locations on the structure.
