Miami-Dade vs DP-50 rating
I have just started looking @ replacement windows in NW FL. I rec'd a good price on DP-50 hurricane resistant windows, but they are not Miami-Dade Co approved. I know the DP-50 rating is for wind resistance up to 173mph, which is more than the rest of the house can tolerate, but what about impact resistance (flying debris)?
Is the DP (Design Pressure) rating only for wind & not impact, where the Miami-Dade Co rating is both?
