Frequently Asked Questions
Do impact windows or accordion shutters save more on Florida homeowners insurance?
Impact windows typically earn larger discounts (up to 45% with full opening protection) compared to accordion shutters (20–35%). The exact savings depend on your insurer and whether you achieve full 'Opening Protection' credit under Florida's wind mitigation inspection.
Are accordion shutters sufficient for a Category 4 hurricane in Florida?
Miami-Dade NOA-approved accordion shutters are rated for Category 4 and 5 wind speeds. The key is proper installation and remembering to close them before the storm — impact windows have an advantage here as no action is required.
What is the ROI on impact windows in Florida?
Most Florida homeowners recover 60–80% of impact window costs through insurance savings, energy savings (10–15% cooling reduction), and increased resale value. In high-risk coastal areas, the insurance savings alone often pay back the cost within 10–15 years.
