Plastic windows in garage door

[jmurray4 (Jay C. Murray)]

Outside the HVHZ. Garage doors with plastic windows in upper panel. Door is rated and bares a wind load sticker. However, Windows/lites are NOT impact or protected by additional shutters.

This would be considered unprotected glazed openings, correct?

[mmeeker (Michael Meeker, CMI)]

Correct in my opinion.

[jshishilla (John Shishilla)]

Yes, at least one

Not an attempt to answer your question, but a link that discusses “plastics” in general, for educational purposes.

Is it plastic or lexan? Is lexan a glazed opening? Is lexan plastic?

From the link in post #4…

Acrylic, Polycarbonate, Plexiglas, Lexan; they are all interchangeable terms in most peoples vocabulary. Getting the terminology correct could save your project from becoming a disaster.

Of all four materials listed above there are really only two plastics involved, polycarbonate and acrylic. Lexan is General Electric’s trade name for Polycarbonate and acrylics trade name is Plexiglas.

Acrylic = Plexiglas
Polycarbonate = Lexan

Just got here so the question really is whether the glazing is impact rated or meets criteria for Miami dade. Most of the time it is not, get info and research it with the manufacturer. If the panels are less than 1/8" thick (and are not made of transparent aluminum) they don’t meet an impact rating.
