Design Pressure Ratings Explained for Clearwater Windows and Doors

Why Design Pressure Matters In Clearwater

Design pressure, often shortened to DP, is the amount of wind force a window or door assembly is built to handle before it starts to flex too much, leak, or fail.

The right rating depends on where the home sits, how tall the structure is, and whether the opening is exposed to open water, an unobstructed corner, or a more sheltered side of the house.

That is also why one product can be perfectly acceptable on one opening and underbuilt for another.

In Clearwater, the rating conversation usually starts with code, not preference.

A common mistake is to assume a window labeled "hurricane" automatically works anywhere on the coast.
