What DP Rating Do I Need in Tampa, FL?

For anyone replacing windows in Tampa, FL, DP rating is one of the first specs worth checking. It is the number that helps show whether a window can stand up to the wind loads a Gulf Coast home is likely to see.

Design pressure is a structural performance rating, not a marketing term, and it measures how well the unit handles wind pushing in and pulling out. The higher the number, the stronger the assembly should be under wind load, though DP is only one part of the picture.
