Building geometry
Roof shape, slope, mean roof height and building dimensions provide the building context.
Project-specific wind pressures
Window and Door Pressure Calculations in Florida
Determination of door and window design pressures can help you select the right product for your building.

Service overview
The right inputs for each opening.
Florida Engineering accepts window pressure requests through a dedicated order form. Clear building information and a coordinated window schedule help establish the calculation scope and reduce missing information at the start.
Site conditions
Project location, exposure and enclosure information inform the wind-pressure analysis.
Opening schedule
Window sizes, locations and elevations connect the results to the openings being reviewed.
A required design pressure is only part of selecting a window. Product approval, impact requirements, permitted sizes and installation details must also be checked for the project.
Before you start
What to send our team
- Job address, county, parcel and project contact information
- Building dimensions, roof type, roof slope and mean roof height
- Available wind-speed, exposure and enclosure information for engineering review
- CAD drawing or completed window schedule with widths, heights, zones and elevations
How it works
From request to review
- 1
Complete the request form
Provide the building information and window schedule.
- 2
Review the project inputs
The team checks the scope and identifies missing details.
- 3
Use the project calculations
Coordinate the pressure requirements with the selected products and permit documents.
Common questions
A few details before you begin.
Can I send drawings instead of typing every opening?
The FE request form asks for a CAD drawing or a manually completed window schedule. Include enough information to locate and size each opening.
Is wind pressure the same as impact resistance?
No. Design pressure concerns wind loading. Impact resistance addresses debris impact performance and is a separate product requirement where applicable.
Will every window have the same pressure?
Not necessarily. Opening size and location, building geometry and site conditions can affect the required pressures.
Start with your window schedule.
Share the project location and available documents so we can confirm the scope and next steps.
