What wind speed can Wrights impact windows withstand?

Wrights impact windows are engineered to withstand wind speeds ranging from 140 mph to over 170 mph, depending on their specific Design Pressure (DP) rating. This level of performance ensures full compliance with the most stringent Florida Building Code requirements for wind-borne debris regions.

Do impact windows reduce homeowner's insurance in Tampa?

Yes, Florida law requires insurance companies to offer premium discounts to homeowners who secure all exterior openings with wind-mitigation features. Installing certified impact windows is one of the most reliable ways to qualify for these substantial annual savings on your home insurance policy.

What is the difference between DP 50 and DP 70 ratings?

A DP 50 window is tested to withstand a structural pressure of 75 pounds per square foot, roughly equivalent to 140 mph winds. A DP 70 window handles up to 105 pounds per square foot, or roughly 200 mph winds, providing superior protection for high-exposure coastal areas.

How to Read Impact Window Ratings for a Tampa Home

Impact-window ratings can be difficult to interpret when a quote shows only a brand and a claim that a unit is “hurricane rated.” For a Tampa home, review the approval for the exact window configuration and ask how it applies to the opening where it will be installed.

Find the product approval

Request the applicable Florida Product Approval or Miami-Dade Notice of Acceptance number for each proposed product. Check the listed manufacturer, model, size range, glass, frame and approved installation methods. A rating for one model or size should not be assumed to apply to a different assembly.

Understand design pressure and exposure

Positive and negative design pressures describe loads a product configuration is approved to resist under specified conditions. The required value depends on the building, opening and applicable code. Ask the installer or project professional to explain how the proposed unit meets the requirement for your opening rather than comparing a single headline number across unrelated products.

Check the whole protection plan

Confirm which windows and doors are impact rated and what protects any remaining openings. Ask how the approved fastening and sealing details will be followed, and who handles permits and inspections. Keep copies of approvals and warranty documents.
