A wind-speed headline does not provide all the information needed to specify a garage door. Wind pressure and wind speed describe different things. Compare documented products for the actual opening, rather than selecting by the largest marketing number.

Ask for the rating on the actual configuration
Request the manufacturer’s documentation for the selected size, glazing and reinforcement. The estimate should identify the door being supplied. A claim about another size in the same range may not describe your order.
Have the property requirements reviewed
DASMA explains that pressure and speed cannot be exchanged through one universal comparison without considering other factors. Give the installer the property information needed for the specification review. If two quotations use different rating formats, ask each provider to identify the evidence that its proposed assembly meets the same project requirements.
Frequently Asked Questions
Is a higher advertised MPH number always the better choice?
It is not a complete comparison. Review the tested configuration, required performance, installation scope and supporting documents.
Does a wind rating also establish impact resistance?
Those are separate performance questions. Ask for documentation addressing each requirement that applies to the project.
