💬 FAQs:

Do I need a wind letter if the door is impact-rated?
Yes — most Florida jurisdictions require site-specific documentation showing the door meets or exceeds calculated wind pressures at your location.

What if I don’t know my product approval number?
No problem — we can help you look it up or work with your contractor to obtain it.

Is this stamped by a licensed Florida PE?
Yes — all wind letters are signed and sealed by a registered Florida Professional Engineer.

What if my opening is larger than 24 ft²?
We’ll automatically adjust our pressure calcs for the correct area and confirm the product is still compliant.
