Hurricane-Rated Impact Windows

Hurricane-rated impact windows are engineered to withstand the intense wind forces and flying debris associated with tropical storms and hurricanes. In Florida — especially in High Velocity Hurricane Zones (HVHZ) — these windows are more than just an upgrade; they’re a necessity. This guide explains what makes a window impact-rated, how they protect your home, and the benefits of installing them.

What Makes a Window 'Impact-Rated'?

Impact-rated windows are built with multiple layers of laminated glass and an inner polymer layer that holds the glass together if it shatters. The frame systems are reinforced with heavier-duty materials, and the overall unit is tested against both wind pressure and impact from debris.

To be classified as hurricane-rated in Florida, the window must pass two main tests:

  • **Large Missile Impact Test (ASTM E1996/E1886):** Simulates debris striking the glass at hurricane speeds.
  • **Cyclic Pressure Test:** Mimics the push-and-pull effects of hurricane wind cycles to test structural integrity.

Florida Code Requirements

Homes located in HVHZ areas — which include Miami-Dade and Broward counties — must use windows that have approved impact ratings or use shutters. Impact windows must carry Florida Product Approval or Miami-Dade Notice of Acceptance (NOA) certification to meet code. These standards verify that the windows have passed rigorous third-party testing.

How Impact Windows Protect Your Home

  • **Debris Resistance:** Prevents glass from shattering inward during storms.
  • **Structural Pressure Control:** Maintains building envelope integrity to avoid uplift and roof failure caused by internal pressurization.
  • **Water Infiltration Resistance:** Advanced seals and reinforced frames reduce the chance of water penetration.
  • **Break-In Prevention:** Laminated glass resists intrusion, increasing home security even outside storm season.

Benefits Beyond Storm Protection

Impact windows are more than just storm protection — they provide year-round advantages:

  • **Energy Efficiency:** Low-E coatings and insulated frames help keep homes cooler and reduce energy bills.
  • **UV Protection:** Blocks over 99% of harmful UV rays that fade furniture, flooring, and artwork.
  • **Noise Reduction:** Significantly reduces outside noise for a quieter home.
  • **Insurance Discounts:** Many insurers offer policy savings when homes are equipped with certified impact-rated openings.
  • **Increased Home Value:** Adds resale appeal and is often a requirement for new construction in South Florida.

Types of Impact Windows

  • **Single-Hung & Double-Hung:** Traditional appearance with one or both sashes operable.
  • **Casement Windows:** Crank open outward for full ventilation and security.
  • **Horizontal Rollers:** Easy to use, ideal for wide openings.
  • **Picture/Fixed Windows:** Provide uninterrupted views without ventilation.
  • **Custom Architectural Windows:** Radius tops, arches, or unique shapes for specialty installations.

Installation & Compliance

Proper installation is just as important as product selection. We ensure every window is installed according to manufacturer guidelines and Florida Building Code. This includes:

  • Engineering and permitting
  • Structural anchoring and buck reinforcement if required
  • Wet sealing and interior finishing
  • Final inspection and documentation
