Insurance Discounts for Impact Windows: What Florida Homeowners Can Expect

Many homeowners start with impact windows for hurricane protection, then quickly ask whether the upgrade will actually lower insurance costs.

The real answer is more nuanced. Impact glass can support wind mitigation credits, but insurers usually care about the whole opening protection package, not just the fact that the glass is stronger.
