Commercial Garage Door Wind Load Requirements: What the Code Asks For and What Proves It

A commercial garage door’s wind requirement is a project-specific positive and negative design pressure in pounds per square foot (psf), not a universal miles-per-hour (mph) rating. The locally adopted code and the project design criteria establish those pressures. The exact door assembly then needs matching test, label, drawing, attachment, and—where required—impact or regional approval evidence.

We are not a manufacturer, a laboratory, a standards body, a building department, an engineering firm, or a repair contractor. See our About page and editorial policy.

What we found

Ten findings, most useful first. ★ Source-reported means we checked the statement in the cited primary document. ● Calculated means we computed it from cited inputs and show the method.

1. ★ There is no single nationwide commercial-door mph or psf requirement. The International Building Code (IBC) is a model code that jurisdictions adopt and may amend. The project’s adopted code, the applicable edition of the American Society of Civil Engineers’ ASCE 7 structural-load standard, site and building inputs, opening, and pressure basis establish the requirement. (ICC, International Building Code overview; ASCE Hazard Tool)
2. ★ Both pressure directions matter. The 2024 IBC model-code provision for garage and rolling doors calls for a permanent label that includes the positive and negative design wind pressure rating. One unsigned psf number is not a complete match. (2024 IBC §1709.5.2.1)
3. ★ The widely repeated 9.6 psf number is not a universal floor for every project. The Door & Access Systems Manufacturers Association (DASMA) Technical Data Sheet (TDS) 155y calls 9.6 psf the minimum value charted inside that guide’s stated assumptions. DASMA separately notes that non-rated doors are available where wind-load requirements are not in force. (DASMA TDS 155y; DASMA TDS 1502)
4. ★ Exposure category can move the guide value sharply. In DASMA’s ASCE 7-22 guide, Exposure C multipliers are 1.49 at a 15 ft mean roof height and 1.44 at 25 ft; Exposure D multipliers are 1.81 and 1.73. These are guide-specific multipliers, not a substitute for the project calculation. (DASMA TDS 155y)
5. ● The paired DASMA guide values changed little between the two editions we compared. Across 428 matched scenario-direction rows in TDS 155v and TDS 155y, the largest absolute change was 0.5 psf and the largest percentage change outside rows pinned at the shared 9.6 psf chart floor was 1.90%. That does not mean the wind speed at a real address stayed the same. (Method and downloads)
6. ★ The five model-code label fields are explicit. The 2024 IBC names the manufacturer, model or series, positive and negative design pressure, installation-drawing reference, and applicable test standard. (2024 IBC §1709.5.2.1)
7. ★ The 1.5× test load is code, not a second door rating. The 2024 IBC says each covered assembly is tested for 10 seconds at 1.5 times design pressure. A door’s usable design-pressure rating is not automatically that higher test pressure. (2024 IBC §1709.5.2)
8. ★ The label alone is not proof of the installed assembly. DASMA’s inspection guidance tells the reader to compare the label with the exact wind-load drawing and then check the configured components and attachment path. (DASMA TDS 181)
9. ★ The door rating does not prove the wall can carry the reactions. The tracks or guides, brackets, anchors, jambs, framing, and building structure complete the load path and need their own project evidence. (DASMA TDS 168; DASMA TDS 181)
10. ★ A static wind rating does not tell you whether the door can operate in wind. DASMA described operational wind load as a separate question and reported work toward a test method; its current standards index does not list a separately titled operational-wind test standard. (DASMA standards; Door + Access Systems, Summer 2025 Tech Corner)

Does my building actually need a wind-rated door?

The answer depends on the code and amendments adopted for the project, the scope of the work, the opening, and the authority having jurisdiction (AHJ)—usually the building department or other enforcing authority. Many exterior commercial-door projects need documented wind resistance. It is not accurate to say that every commercial door in every U.S. building must carry the same minimum rating—or that a door with no wind label is automatically unlawful everywhere.

The International Building Code is a model code. A governmental jurisdiction adopts an edition, may amend it, and decides how it applies to new construction, replacement, repair, and alteration. The newest IBC or ASCE 7 edition does not automatically govern a project. (ICC, International Building Code overview)

The current ASCE Hazard Tool lets a user select ASCE 7-10, ASCE 7-16, or ASCE 7-22 and retrieve site-specific hazard data. That tool helps establish inputs. It does not select or approve a door. (ASCE Hazard Tool)

What the 9.6 psf number really means

DASMA’s TDS 155y shows selected garage- and commercial-door pressure scenarios under ASCE 7-22 and the 2024 IBC. Its notes call 9.6 psf the minimum value charted. That is a boundary inside that guide, not a national declaration that every commercial door must be rated to at least 9.6 psf.

The distinction matters because:

• The guide has stated building, height, opening, topography, enclosure, roof-slope, and wall-zone assumptions.
• Openings outside those assumptions need a project-specific determination.
• A jurisdiction may use another adopted edition or amendment.
• A replacement or repair may follow an existing-building or local permitting path.
• DASMA’s label guidance acknowledges that non-rated doors exist where a wind-load requirement is not in force.

Sources: DASMA TDS 155y, general notes; DASMA TDS 1502.

What changes from one project to another

The project requirement can change with all of these:

Sources: DASMA TDS 155y; DASMA TDS 168; ASCE Hazard Tool.

What about replacing a door in an existing building?

The building department decides which adopted-code and existing-building provisions apply to the work. An insurer or customer may also impose a separate evidence requirement.

Do not assume that “same size” means “same requirement,” and do not assume that every replacement triggers a full new-construction path. Before ordering, identify:

1. The project jurisdiction and permit path.
2. The pressure requirement that will be used.
3. Whether the existing jambs, header, wall, and anchors are being reused.
4. Whether impact or a special product-approval program applies.
5. Which documents the reviewer or insurer expects.

DASMA’s FAQ says retrofit questions belong with the authority having jurisdiction and notes that an insurer may have its own mitigation requirements. (DASMA TDS 168)

Who decides the number, and what is it made of?

The project design process or building official establishes the required design pressure and its inputs. A door manufacturer or supplier can use confirmed project information to select a product, but should not invent the project’s exposure, code edition, pressure basis, or supporting-wall design.

DASMA assigns the exposure-category determination to the design professional or building official because it depends on the actual site. Manufacturer selection tools can be useful for preliminary selection, but DASMA itself says calculated values are preliminary and final responsibility lies with a registered design professional. (DASMA TDS 193; DASMA Technical Data Sheets)

Who owns which decision

Sources: DASMA TDS 168, TDS 181, and TDS 193. The table organizes the source responsibilities into one workflow.

The eleven inputs behind one pressure number

DASMA’s current ASCE 7-22 guide identifies basic wind speed, exposure category, the allowable-stress load factor, mean roof height, door location on the building, wind directionality, topographic effects, ground elevation, roof pitch, enclosure category, and door area as inputs behind the published values. (DASMA TDS 155y)

Two details often surprise buyers:

• Where the opening sits on the wall matters. The published guides have a stated end-zone-overlap limit. A wider opening or different corner condition can put the project outside the chart.
• The compass direction on the plan is not the same as a pressure-zone decision. DASMA’s FAQ says the method accounts for wind toward and away from the door; the project wall location and pressure zone still matter. (DASMA TDS 168)

The one question to ask first

What is the required design pressure for this opening, positive and negative, in psf—and what pressure basis and code edition were used?

Ask for the answer in writing. Every downstream check—the quote, label, drawing, report, installation, and approval—depends on it.

Why is a “150 mph door” not enough?

A wind-speed statement does not establish the pressure rating a commercial door needs. Wind speed is one input. The product evidence and project comparison are expressed in positive and negative pressure, usually in psf, under a stated basis.

A manufacturer may use wind-speed language in marketing or a preliminary selection tool. That language is not a substitute for the project-required +DP and −DP, the exact product rating, or the installation evidence. DASMA’s PSF-versus-MPH guidance makes the same distinction. (DASMA TDS 194)

Terms people swap for each other

Sources: DASMA TDS 168, TDS 178, TDS 194, and the DASMA standards index.

The 0.6 factor—and the trap in it

ASCE 7 wind criteria and product ratings can appear on different load bases. DASMA’s guides state that their published values already include the 0.6 allowable-stress factor. The 2024 IBC model-code provisions also use a 0.6 conversion in stated contexts.

That does not mean every pressure number should be multiplied by 0.6. First establish:

1. What the supplied number represents.
2. Which ASCE 7 and code edition applies.
3. Whether the governing method permits the conversion.
4. Whether the number was already converted.
5. Whether the product rating is on the same basis.

Illustrative arithmetic only: if a project document expressly identifies a required strength-basis pressure of +30/−34 psf and the governing method permits conversion, 0.6 × 30 = +18 psf and 0.6 × 34 = −20.4 psf on the allowable-stress basis. If the project document already supplies ASD pressure, applying 0.6 again would be wrong.

Sources: DASMA TDS 155y, note 1; DASMA TDS 168, load-basis discussion; 2024 IBC Chapter 17.

Test pressure is not a second rating

The 2024 IBC model provision says each covered assembly is tested for 10 seconds at a load equal to 1.5 times design pressure. That is a test requirement, not permission to relabel the door at the higher value.

For an ASD design pressure of 25 psf, the stated model-code test load is:

25 psf × 1.5 = 37.5 psf

The assembly is still documented by its design-pressure rating, test standard, model/configuration, and drawing. (2024 IBC §1709.5.2)

Effective wind area changed in the 2016 ASCE cycle

DASMA explains that older wording could be read as using each structural component of a garage door as the effective wind area. The ASCE 7-16 wording treats a typical single-unit door assembly as one unit, so its overall area is used. (DASMA TDS 178)

That does not create a do-it-yourself pressure calculation. It does mean an older specification based on one section’s area may deserve review by the project design professional. Complex, mulled, or unusual assemblies still need the applicable manufacturer and engineering treatment.

How much can exposure category move the number?

Exposure category is one of the largest variables in the DASMA guide scenarios. It describes the terrain and obstructions around the project, and it belongs to the project design process—not to a door supplier’s guess.

DASMA publishes these ASCE 7-22 multipliers relative to its Exposure B chart values:

Source: DASMA TDS 155y, Exposure C and D chart notes. These multipliers apply to the guide’s stated equations, heights, and assumptions; they are not universal project factors.

What that looks like in one published guide scenario

For a 14 ft × 14 ft commercial door, 25 ft mean roof height, and 140 mph basic wind speed, TDS 155y publishes an Exposure B value of +14.7/−16.4 psf.

● Uptime calculation using DASMA’s published value and multiplier:

Source inputs: DASMA TDS 155y, commercial-door charts and Exposure C/D notes. Rounded to one decimal place. This is a guide example, not a project design pressure.

The arithmetic shows why exposure deserves attention. It does not prove that the example building is Exposure B, C, or D, and it does not show that a particular project fits the guide limits.

How the three categories are described

DASMA’s TDS 193 summarizes the ASCE exposure categories:

• Exposure B covers urban, suburban, wooded, or similarly obstructed terrain where the qualifying roughness extends far enough upwind under the standard’s rules.
• Exposure C covers open terrain with scattered obstructions generally less than 30 ft high, including open country and grasslands.
• Exposure D covers the most severe open-water and unobstructed shoreline conditions within the standard’s stated distance and direction rules.

The exact determination is not a neighborhood label. It depends on the project location, upwind direction, distance, building height, and governing ASCE edition. (DASMA TDS 193)

The assumption worth checking

TDS 193 says ASCE 7 commentary indicates that roughly 60% to 80% of buildings may correspond to Exposure B and warns that the IBC can lead to a tendency to assume Exposure C in cases where B may apply. That is an attributed commentary statement, not a Uptime estimate and not a reason to change a project classification without the responsible design or AHJ decision. (DASMA TDS 193)

A fair question is:

Which exposure category did the project use, and where is that decision recorded?

Exposure can also change as surrounding buildings or terrain conditions change, so an old calculation is not automatically transferable to a new project.

What changed in DASMA’s ASCE 7-22 guide?

Within the matched scenarios DASMA publishes in both its ASCE 7-16 and ASCE 7-22 guides, the pressure values changed little. That result is specific to the paired guide cells. It does not prove that the site wind speed, adopted code, risk category, tornado check, or final pressure at a real address stayed the same.

How we compared the guides

DASMA TDS 155v charts selected scenarios under ASCE 7-16. DASMA TDS 155y charts corresponding scenarios under ASCE 7-22 and the 2024 IBC.

We joined every row that shared the same:

• Door group.
• Exposure category.
• Mean roof height.
• Door size.
• Basic wind speed.
• Pressure direction.

We then calculated:

magnitude_change_psf = |ASCE 7-22 source value| − |ASCE 7-16 source value|

percent_change =
(|ASCE 7-22 source value| − |ASCE 7-16 source value|)
÷ |ASCE 7-16 source value| × 100

Rows at 9.6 psf in both guides were flagged because a shared chart floor can hide what an unconstrained equation would have done. The public CSV contains each matched scenario, the derived change, the direction, the floor flag, and both source-page locators. It does not republish both source tables wholesale.

What the comparison shows

● Calculated from DASMA TDS 155v and TDS 155y:

Source and method: Uptime calculation from DASMA TDS 155v and TDS 155y. There are 428 matched scenario-direction rows in total. Forty-five equal 9.6 psf in both guides and are excluded from the percentage summary. Maximum absolute magnitude change across all 428 rows: 0.5 psf. Values verified 19 September 2026. Download the 428-row derived comparison.

Three things stand out.

Exposure B never rose in the non-floor matched rows. It fell in 179 and was unchanged in 36.

Exposure D more often rose than fell. It rose in 51 of 84 non-floor rows, fell in 13, and was unchanged in 20.

Edition-to-edition cell changes were small beside the guide’s exposure multipliers. That comparison is descriptive, not a universal measure of which design variable matters most. A real project can still change materially because the applicable map, risk category, site conditions, adopted edition, or other inputs changed.

The ASCE 7-22 tornado note

TDS 155y includes a note for Risk Category III and IV buildings directing the user to ASCE 7-22 Chapter 32 to determine whether tornado pressure exceeds the wind pressure. That note is absent from TDS 155v. (DASMA TDS 155y, general note 4)

That is not a statement that every hospital, fire station, assembly building, or essential facility has a higher door pressure. It is a required comparison under the applicable ASCE 7-22 path.

What this comparison does not tell you

It does not show:

• Whether the mapped wind speed at a project address changed.
• Whether the jurisdiction adopted either edition.
• Whether local amendments apply.
• Whether the project fits the DASMA chart assumptions.
• Whether the building is Risk Category III or IV.
• Whether tornado pressure governs.
• Whether the door assembly, support, or installation is acceptable.

Use the comparison to understand the published guide delta—not to bypass the project design criteria.

What does the model code say about testing and labels?

The 2024 IBC model-code text gives a clear baseline for exterior door testing and for garage and rolling door labels. The locally adopted edition still controls.

The 2024 IBC baseline in plain English

Source: 2024 IBC Chapter 17, §§1709.5.2–1709.5.3. This table paraphrases the official text rather than reproducing the section wholesale.

ANSI/DASMA 108-2017 is titled Standard Method for Testing Sectional Garage Doors and Rolling Doors: Determination of Structural Performance Under Uniform Static Air Pressure Difference. DASMA’s current standards index still lists that edition. (DASMA standards)

Why the exact test and report still matter

A code section naming a test method does not establish that a particular door passed it at the required pressure, size, and configuration. The submittal still needs the exact product evidence:

• Manufacturer and model or series.
• Door size and configuration.
• Positive and negative design-pressure rating.
• Test or evaluation report.
• Installation drawing and revision.
• Reinforcement, track or guide, bracket, anchor, and substrate details.
• Glazing and impact evidence where applicable.
• Any product-approval or regional-program record.

The 2024 IBC also says test specimens and construction must be representative of the materials, workmanship, and details normally used in practice. (2024 IBC §1709.7)

Why a guide table and a project pressure schedule can differ

DASMA’s FAQ explains that a wide door can overlap more than one wall-pressure zone, so a weighted-average treatment may be used under the stated method. The project pressure schedule may use a more specific calculation, geometry, or zone assignment. (DASMA TDS 168)

Neither source should be stripped of its assumptions. The project’s accepted pressure schedule is what the product submittal needs to meet.

Which current DASMA guide is closest to the project path?

Source: DASMA’s official Technical Data Sheets index and the guide covers. A guide is not an adopted code or project approval.

The guide boundary conditions

TDS 155v and TDS 155y state important assumptions and limits. The published values are not a universal lookup for every opening.

Among the stated conditions:

• Enclosed-building assumptions.
• Topographic factor of 1.00.
• Ground-elevation factor of 1.00.
• Mean roof height no greater than 25 ft.
• Door area and wall-zone-overlap limits printed in the guide.
• Chart-specific roof-slope conditions.
• Separate garage-door and commercial-door chart notes.

The commercial-door tables in TDS 155y are limited to roof slopes of 10 degrees or less. The garage-door tables use their own roof-slope treatment and notes. The guide sends openings outside its limits back to an ASCE 7 determination. (DASMA TDS 155y)

Are pressure rating and impact rating the same?

No. Static design-pressure resistance and debris-impact resistance answer different questions and use different evidence.

A door can have a high positive and negative pressure rating without having the required impact qualification. An impact-qualified assembly still needs to meet the project’s static pressure requirement.

What each evidence type proves

Sources: 2024 IBC §1709.5.3, DASMA standards, and the official Florida and Texas program sources in the next section.

Which impact standard applies?

DASMA currently lists ANSI/DASMA 115-2017, titled Standard Method for Testing Sectional Garage Doors: Determination of Structural Performance Under Missile Impact and Cyclic Wind Pressure. The 2024 IBC §1709.5.3 text cited on this page addresses exterior glazed openings and names ASTM E1886 and ASTM E1996 for impact protective systems. Florida, Miami-Dade, Texas, a project specification, or an insurer may use additional or different accepted paths.

Do not choose an impact standard from a generic article. The project needs the exact adopted code, opening type, program, test edition, report, and product configuration.

What glazing changes

Adding glazing does not by itself rewrite the building’s required design pressure for the opening. It can change the product configuration, impact requirement, approval record, and maximum qualified size. The submittal should identify the glazing type, location, and extent and match the exact report or drawing. (DASMA TDS 168; DASMA TDS 181)

A fire rating is another separate program. If the opening also uses a rolling fire door, see fire door drop test requirements.

What proof do Florida, Miami-Dade, and Texas use?

The model-code baseline is only the first layer. Florida’s state product database, Miami-Dade’s Product Control program, and the Texas windstorm program add their own records and project steps.

This section is not a 50-state survey. It shows three current, verifiable examples of why “tested door” and “accepted project” are not the same statement.

The model-code baseline

Under the 2024 IBC example, start with:

1. Project-required positive and negative pressure.
2. Exact manufacturer and model or series.
3. Exact size and configuration.
4. Applicable test or evaluation evidence.
5. Permanent label fields.
6. Referenced installation drawing.
7. Attachment and supporting-structure evidence.
8. Inspection and AHJ acceptance.

Florida statewide

The Florida Building Commission identifies the Florida Building Code, 8th Edition (2023) as effective December 31, 2023. Its Product Approval search identifies the current code version and lets a user filter or review fields including:

• Approved for use in the High-Velocity Hurricane Zone.
• Approved for use outside the HVHZ.
• Impact resistant.
• Positive design pressure.
• Negative design pressure.
• Product model, number, or name.
• Evaluation and installation documents in the exact product record.

Sources: Florida Building Commission and Florida Product Approval Search, verified 19 September 2026.

The database record is not a substitute for reading the exact documents. Match:

• FL number and revision.
• Manufacturer and model.
• Opening size.
• Door construction and options.
• Impact status.
• HVHZ or outside-HVHZ status.
• Positive and negative pressure.
• Installation instructions.
• Limits of use.
• Current code version and approval status.

Florida’s site also shows materials related to a 2026 code update process. This page does not assign a future effective date that the Commission has not verified on the current official page.

Miami-Dade Product Control

Miami-Dade maintains a separate Product Control and Notice of Acceptance (NOA) search. Current search results list exact product descriptions and expiration dates. For example, the official database contains current commercial sectional and rolling-door NOAs with named maximum widths, glazing options, and expiration dates. Those are product-specific examples, not general ratings. (Miami-Dade Product Approval; current Product Control example)

For an HVHZ project, verify:

• Exact current NOA number.
• Applicant/manufacturer.
• Door series and size.
• Impact status and glazing configuration.
• Positive and negative pressure.
• Approved drawings and installation details.
• Substrate and anchor limits.
• Expiration date.
• Any project-specific product-control or building-department requirement.

Miami-Dade still posts older application checklists in its forms library. A dated checklist can help explain the evidence program, but it should not replace the current exact NOA, current code, or project instructions.

Texas TDI/TWIA windstorm program

Texas states that Applications for Certificate of Compliance (WPI-1) starting April 1, 2026 must be certified under the 2024 IRC or 2024 IBC. Construction must be certified to be eligible for windstorm coverage through the Texas Windstorm Insurance Association. TDI also says:

• The designated catastrophe areas did not change with the code adoption.
• Required wind speed is determined for each structure based on location.
• The ASCE Hazard Tool is one official resource named for the lookup.
• Most designated catastrophe areas are now in the wind-borne-debris region.
• Debris requirements follow the 2024 codes for the program.

Source: Texas Department of Insurance, Adopted Building Codes, verified 19 September 2026.

TDI’s product-evaluation FAQ was last updated in July 2025, before the April 2026 code transition, and still cites older editions in places. It remains useful for understanding label and evaluation evidence, but where it conflicts with the current adopted-code page, use the current program requirements and obtain project guidance. (TDI Product Evaluations FAQ)

TDI also warns that posting a link to a third-party evaluation report does not itself mean the report proves compliance. (TDI Product Evaluations)

The proof layers side by side

Sources: official ICC, Florida Building Commission, Miami-Dade Product Control, and Texas Department of Insurance pages linked above. “Yes” means the product record is one part of the project evidence, not automatic approval of the installed opening.

How do I check the door in front of me?

Start with the project pressure schedule, then read the permanent label, obtain the exact drawing it references, and compare the installed assembly and load path with the accepted evidence. A label without the project requirement or drawing is incomplete proof.

DASMA’s inspection guidance is direct: do not rely on a wind-load label alone. Garage doors are assembled on site from components that can be configured in different ways and quantities. (DASMA TDS 181)

What the 2024 IBC model-code label identifies

Source: 2024 IBC §1709.5.2.1. The positive and negative pressure values are two fields within the provision’s five named label categories.

The arithmetic for a documented pressure comparison

Only compare values after confirming that they use the same basis and apply to the exact assembly.

Illustrative example:

• Project document expressly gives +30/−34 psf on a strength basis.
• The governing method permits the 0.6 conversion.
• The exact door label gives +20/−22 psf on the ASD basis.

Required positive ASD = 30 × 0.6 = 18.0 psf
Required negative ASD magnitude = 34 × 0.6 = 20.4 psf

Positive margin = 20 − 18.0 = 2.0 psf
Negative margin = 22 − 20.4 = 1.6 psf

That is a basic numerical pressure match in both directions. It does not verify:

• The conversion is permitted for the real project.
• The exact size and configuration.
• Impact status.
• Drawing and anchors.
• Supporting wall and load path.
• Product approval.
• Installation.
• AHJ or program acceptance.

The 2024 IBC’s stated test load for an 18.0 psf design pressure would be 27.0 psf, and for 20.4 psf it would be 30.6 psf, because design pressure × 1.5 = test pressure under the cited provision. That test arithmetic is not a second design rating. (2024 IBC §1709.5.2)

Can I verify a door that is already installed?

You can inventory the evidence and identify gaps. You cannot establish project compliance from a label or visual inspection alone.

Editorial framework built from DASMA TDS 180, TDS 181, the Florida Product Approval database, Miami-Dade Product Control, and TDI program guidance.

Unknown is not zero. A missing label or report is an evidence gap. Do not invent a rating from the number of struts, the apparent panel thickness, a model-family brochure, or a similar door nearby.

A facility representative can safely:

• Photograph a visible label without entering a hazard area.
• Record the opening ID and dimensions.
• Gather permits, orders, drawings, and maintenance records.
• Record visible damage without touching springs, cables, brackets, or loose components.
• Compare document identifiers and revisions.
• Use the checklist to identify missing evidence.

If the problem is operational—binding, crooked travel, damaged track, a broken operator, or a door that will not close—that is a different search job. See commercial overhead door problems.

Does a wind-rated door still open in wind?

Not necessarily. A static wind rating describes the closed assembly under the stated pressure test. Opening and closing while wind acts on the door is a separate performance question.

DASMA reported in Summer 2025 that operational wind load was being requested more often, that manufacturers used their own methods, and that its Rolling Door Division Research Committee had begun work toward a standard test method with initial testing at Intertek in York, Pennsylvania. (Door + Access Systems, Summer 2025 Tech Corner)

As of the 19 September 2026 verification date, the DASMA standards index did not list a separately titled operational-wind test standard. That index check does not prove that no broader product standard contains a related provision.

If a specification calls for operational wind performance, require the manufacturer to state:

• The test or calculation method.
• Door model, size, and configuration.
• Wind-pressure direction and magnitude.
• Whether the door was opening, closing, or holding position.
• Cycle count and acceptance criteria.
• Required controls, guides, windlocks, or operating restrictions.
• Whether the result is independently tested, manufacturer-tested, or calculated.

A correctly rated closed door may still be unsafe or unable to move under wind. Windlocks, guide contact, curtain pressure, panel deflection, seals, and the operator all affect operation. Do not improvise operation during a storm or bypass an interlock to make a door move.

Methodology

What we did. We opened the primary sources named on this page at the issuer’s site or official publishing platform and rechecked them on 19 September 2026. For PDFs, we read the relevant pages and chart notes. We recorded the publisher, document title, edition or revision where stated, exact locator, verification date, authority type, and scope limitation.

How we built the cross-edition comparison. We transcribed the matched scenario values from DASMA TDS 155v and TDS 155y, joined the rows by door group, exposure, mean roof height, door size, basic wind speed, and pressure direction, and calculated the change in pressure magnitude. The public 428-row CSV publishes the scenario, derived change, direction, floor flag, and source-page locators. It does not republish both DASMA pressure tables wholesale.

The formulas. For each matched row:

magnitude_change_psf = |7-22 source value| − |7-16 source value|

percent_change =
(|7-22 source value| − |7-16 source value|)
÷ |7-16 source value| × 100

For the exposure worked example:

Exposure C or D example value =
DASMA’s published Exposure B value × DASMA’s published multiplier

All arithmetic was recalculated with a tool. The CSV, JSON, article summary, and worked example were then checked against one another.

What ★ and ● mean.

• ★ Source-reported: checked in the named primary source.
• ● Calculated: computed from verified source inputs with the formula shown.

Neither symbol means “less verified.” A calculated value is publishable only when its inputs, formula, unit, and scope are all clear.

Source hierarchy. We used:

1. Official adopted-program and governmental material.
2. Official model-code text and publisher adoption statements.
3. Official standard-publisher pages.
4. DASMA technical data sheets and standards indexes.
5. Manufacturer material only where an exact named product example would be useful.
6. Uptime’s transparent calculations and editorial organization.

What we did not do. We did not:

• Calculate a project design pressure.
• Inspect, test, install, repair, certify, or approve a door.
• Read the complete paid text of ASCE 7, ASTM E330, ANSI/DASMA 108, or ANSI/DASMA 115 clause by clause.
• Reproduce protected standards tables or both DASMA chart sets wholesale.
• Survey every state or local code adoption.
• Complete a repository-level or XML-sitemap inventory of every Uptime route from this research environment.
• Claim that a manufacturer specification is independent testing.
• Assign a public reuse license to the dataset.

Missing-value rule. Unknown, unavailable, not applicable, and unverified are different states. We do not turn a missing value into zero. A missing label or report is an evidence gap, not proof of zero capacity.

Corrections. Report a moved source, calculation issue, or factual correction through the contact page. A substantive evidence change increments the dataset version and changes the visible verification date only after the sources are actually rechecked.

Limitations

• This page cannot tell you the required pressure for a building. It explains the evidence chain and comparison method. The project design and approval process supplies the actual requirement.
• The locally adopted code controls. The 2024 IBC is used as a current model-code example, not as a claim that every jurisdiction has adopted it.
• The DASMA charts have stated limits. Building enclosure, topography, elevation, mean roof height, roof slope, opening area, wall zone, and other conditions can put a project outside them.
• The 9.6 psf value is a chart floor in TDS 155y, not a universal project minimum.
• The 428-row comparison holds wind speed and the other matched scenario labels constant. It does not capture a changed wind map or site-specific project calculation.
• The exposure multipliers are those printed in TDS 155y for its guide method. They are not a universal multiplier for every building.
• The jurisdiction section covers the model-code baseline plus Florida, Miami-Dade, and the Texas windstorm program. It is not a 50-state or every-county survey.
• The Texas product-evaluation FAQ predates the April 2026 code transition. The current adopted-code page and project instructions control where the pages differ.
• Miami-Dade’s older forms and checklists remain useful background but do not replace the current exact NOA or current project requirements.
• Manufacturer and product-program evidence is configuration-specific. A named series or family page does not establish a rating for every size or option.
• No separately titled operational-wind test standard was identified on DASMA’s current standards index. That index check does not establish the contents of every broader product standard. Manufacturer claims may use different methods.
• Source URLs, product approvals, editions, and TDS revisions change. Verify the current record before a submittal.

When citing the cross-edition finding, carry these qualifications with it:

• It compares 428 matched scenario-direction rows in DASMA TDS 155v and TDS 155y.
• The source pressure values belong to DASMA.
• Uptime calculated the row-level magnitude and percentage changes.
• Forty-five rows are at the shared 9.6 psf chart floor.
• The comparison does not capture a changed site wind map or project calculation.

No public reuse license is asserted for the dataset. Third-party source material remains subject to its original rights.

Download the data

Seven CSVs and one combined JSON. The six evidence tables contain 568 rows; the separate data dictionary contains 59 field-definition rows. No sign-up or email gate.

Reading the files honestly:

• Blank, unknown, unavailable, not applicable, and unverified are not zero.
• Source-page locators show where to check the DASMA comparison rows.
• The delta CSV contains Uptime’s derived changes, not both DASMA tables.
• The JSON has "license": null deliberately.
• Dataset version and source verification date change only after a substantive recheck.

Questions people ask

What psf does my commercial garage door need?

No national web page can supply one number for every building. Obtain the project-required positive and negative pressure, the pressure basis, and the adopted code edition from the accepted project design or building official.

Is 150 mph equal to one commercial-door psf rating?

No. Wind speed is one input. Exposure, height, geometry, enclosure, wall location, opening size, effective wind area, pressure basis, and other factors affect the result.

Does the direction my door faces change the requirement?

DASMA’s FAQ says worst-case wind toward and away from the door is considered, so compass direction alone is not the deciding variable. The opening’s wall zone, corner relationship, and project calculation still matter. (DASMA TDS 168)

My door size is not on the DASMA chart. What do I do?

Do not invent an interpolation rule. Obtain a project-specific pressure and exact manufacturer evidence for the proposed size. DASMA TDS 180 explains that ratings may differ by size and that untested sizes need accepted analysis or additional evidence. (DASMA TDS 180)

Is a taller building’s door requirement always higher?

Height is one pressure input, and the DASMA guides publish separate 15 ft and 25 ft mean-roof-height values. The final result still depends on the complete project method and conditions.

What is a “WindCode,” “windstorm,” or numbered manufacturer package?

It is a manufacturer’s product or option language, not a universal code classification. Ask for the exact model/configuration, positive and negative psf rating, test/evaluation evidence, and installation drawing.

Who verifies whether the wall can take the door loads?

The project needs accepted structural evidence for the supporting jambs, header, wall, anchors, and load path. DASMA separates that building-side responsibility from the door manufacturer’s rated assembly. (DASMA TDS 168; TDS 181)

Can I add struts or wind posts to make an existing door wind rated?

Field-added parts do not create a tested or approved rating by themselves. The higher rating must come from accepted manufacturer or project documentation for the exact resulting assembly.

Does a matching label mean the door is compliant?

No. It is one part of the evidence. The project pressure, pressure basis, exact size/configuration, drawing, anchors, support, impact requirement, installation, approval record, and AHJ acceptance still need to match.

Is impact resistance automatically required in every wind-borne-debris region?

Use the exact adopted code and opening type. The 2024 IBC §1709.5.3 text cited here is written for exterior glazed openings, while Florida, Miami-Dade, Texas, project specifications, or insurance programs can impose their own product and impact evidence rules.

Can a wind-rated door be operated during a storm?

A closed-door static rating does not prove operational performance. Obtain the manufacturer’s operational method, pressure, configuration, and restrictions, and do not improvise operation or bypass safety controls.
