  • DP50 vs Miami-Dade Hurricane Window Rating

    I rec'd an estimate for replacement windows in NW FL and they have the DP (Design Pressure) 50 rating for wind resistance up to 173mph, but are not Miami-Dade Co approved.

    I know the Miami-Dade Co rating includes wind & impact resistance, but does the Design Pressure rating system include both? Do H/O insurers discount premiums for DP50 windows?
