One building.
Start to finish.

Follow a complete wall-pressure calculation from the property to the report, then start your own Florida project when you’re ready.

Start your project

Demonstration building with fixed illustrative inputs. No property lookup was performed.

01 / Property

Every calculation starts with the location.

For your own project, you enter a Florida address and confirm the matched property. This example uses a fictional building with the assumptions shown here.

See where each pressure applies.

Zone 4 covers the wall field. Zone 5 follows the exterior corners. Select a zone to see it on the plan and elevation.

Building plan with automatic wall zonesIllustrative 70 by 50 foot rectangular building. Blue Zone 4 covers exterior wall runs between corners. Magenta Zone 5 extends 5 feet from each corner. The least horizontal dimension B is 50 feet. The same building is shown in the adjacent gable elevation.

Sample building elevation and wall zonesA 50-foot-wide building with a sloped roof, 24-foot eaves and a 34-foot ridge. Its mean roof height is 29 feet. Magenta Zone 5 covers the 5-foot corner strips; blue Zone 4 covers the wall between them. The outer windows cross the zone boundaries. This is an illustrative building, not a project calculation.

See how the wall zones relate to the building and its windows.

03 / Pressure results

Compare wall and corner pressures.

Positive values act inward. Negative values act outward. Both directions matter when reviewing a window or wall component.

For this example

The corner zone has the higher outward suction. These values apply only to the listed example inputs and the 10 ft² effective wind area.

Preliminary demonstration only. Not for construction, permitting or selection of a product for an actual property.
