How to Choose the Best Impact Resistant Windows for Your Home
A Complete Buying Guide for Homeowners in Florida's Hurricane Zones
If you live in Florida, you already know that strong storms are part of life. Wind, flying debris, and heavy rain can damage a home in minutes. This is why more homeowners are switching to impact resistant windows. These windows are built to take a hit and keep your family, your furniture, and your walls safe.
But not all impact windows are the same. Frame material, glass thickness, design pressure rating, and installation quality all change how well a window performs. Picking the wrong one can mean paying more and getting less protection. This guide walks you through every factor you need to check before you buy, so you can choose windows that actually protect your home.
Quick answer: The best impact resistant windows for your home are laminated glass windows with a frame material suited to your budget, a Design Pressure (DP) rating matched to your wind zone, Miami-Dade NOA or ASTM E1996 approval, and professional installation from a licensed local contractor.
What Are Impact Resistant Windows?
Impact resistant windows are windows built with laminated glass. Two or more layers of glass are bonded together with a strong plastic interlayer, usually PVB (polyvinyl butyral) or SentryGlas. When the glass is struck by wind-borne debris, it may crack, but the interlayer holds the pieces together. The window stays in one piece instead of shattering, which keeps wind and rain out of your home.
A true impact window is made of three main parts working together:
- Laminated glass – the outer barrier that resists penetration from flying debris
- Reinforced frame – vinyl, aluminum, wood, or fiberglass, built to hold the glass under pressure
- Multi-point locking hardware– keeps the sash sealed tightly against the frame during high winds
Why Every Oakland Park Homeowner Should Consider Impact Resistant Windows
South Florida homes face hurricanes, tropical storms, and year-round humidity. Standard windows were never designed for this kind of pressure. Here is what impact resistant windows give you that regular windows cannot:
- Storm protection – rated to resist large and small wind-borne debris during hurricanes
- Home security – the laminated glass is far harder to break through than standard glass, which discourages break-ins
- Noise reduction – the thick, layered glass blocks traffic and storm noise significantly better than single-pane glass
- Lower energy bills – tighter seals and Low-E coatings reduce heat gain and keep A/C costs down
- Insurance savings – many Florida insurers offer a wind mitigation discount for approved impact windows
- No storm-prep scramble – no shutters to install or plywood to nail up before every storm warning

How Impact Resistant Windows Are Tested and Rated
Before you compare products, it helps to understand how these windows are actually rated. Manufacturers cannot just call a window "hurricane proof" — it has to pass recognized tests.
| Standard / Rating | What It Measures | Why It Matters |
|---|---|---|
| ASTM E1996 / E1886 | Large and small missile impact resistance plus cyclic wind pressure | The core national standard impact windows must pass |
| Miami-Dade NOA (Notice of Acceptance) | Product approval under the toughest building code in the country | A strong sign the window can handle South Florida conditions |
| Design Pressure (DP) Rating | How much wind load and structural pressure a window can resist | Must match or exceed your home's wind zone requirement |
| Florida Building Code (FBC) Approval | State-level compliance for structural and impact performance | Required for permitting on most Florida homes |
Key Factors to Consider When Choosing Impact Resistant Windows
This is the part most buying guides skip. Choosing impact resistant windows is not just about price — it is about matching the product to your home, your budget, and your local wind zone. Here are the eight factors that matter most.
1. Frame Material
The frame holds the glass in place under pressure, so its strength and durability matter as much as the glass itself.
| Frame Material | Durability | Maintenance | Best For |
|---|---|---|---|
| Vinyl | Good, resists corrosion | Low maintenance | Budget-friendly homes, coastal areas |
| Aluminum | Very strong, slim profile | Low, but can pit near salt air | Modern homes wanting large glass panels |
| Fiberglass | Excellent, very stable | Very low | Homeowners wanting long-term value |
| Wood-clad | Strong, classic look | Higher, needs sealing | Traditional or historic-style homes |
2. Glass Type and Thickness
Look for laminated glass with a PVB or SentryGlas interlayer of at least 0.090 inches for standard protection, or thicker for higher wind zones. Thicker interlayers offer better resistance and also improve sound dampening. Ask your contractor for the exact interlayer thickness in writing — this detail is often left out of sales conversations.
3. Impact Rating: Large Missile vs. Small Missile
- Large Missile Impact – rated for ground-floor windows exposed to flying debris like tree branches or roof tiles
- Small Missile Impact – used for upper-floor windows above 30 feet, where only small debris typically reaches
Make sure your contractor specifies the correct rating for each window location on your home, not a single rating for the whole house.
4. Design Pressure (DP) Rating
Every Florida address falls into a wind zone with a minimum required DP rating, based on distance from the coast and local building code. A window with too low a DP rating may fail inspection or, worse, fail during an actual storm. Always ask for the DP rating in writing and confirm it against your county's wind speed map.
5. Energy Efficiency
- Look for a Low-E coating to reduce heat transfer and UV damage to furniture and flooring
- Check the U-Factor — lower numbers mean better insulation
- Check the SHGC (Solar Heat Gain Coefficient) — lower numbers mean less heat entering your home
- Ask if the window is ENERGY STAR certified for potential utility rebates
6. Style and Aesthetic Compatibility
Impact windows now come in almost every style: single-hung, double-hung, casement, sliding, picture, and bay windows. A reputable contractor should be able to match impact-rated glass to your home's existing architecture without changing its curb appeal.
7. Warranty Coverage
- Glass warranty – covers seal failure, fogging, and impact defects
- Frame warranty – covers warping, discoloration, or hardware failure
- Labor/installation warranty – covers workmanship separately from the product itself
A window is only as good as the installation behind it, so always confirm whether labor is covered and for how long.
8. Professional Installation Quality
Even a top-rated window will underperform if it is installed incorrectly. Poor flashing, weak anchoring, or the wrong fasteners can let water and wind pressure in around the frame, no matter how strong the glass is. This is exactly why homeowners are encouraged to work with a licensed, experienced local contractor rather than the lowest bidder.
And windows are only one part of a storm-ready home. Wind can just as easily find a way in through an aging or under-rated roof. If your roof is due for an upgrade, a properly installed, wind-rated system such as Metal Roofing in Oakland Park, FL pairs naturally with impact windows to give your home complete, code-compliant protection from roofline to window frame.

| Daily Use | Full natural light, unobstructed views | Blocks light and view when closed |
| Noise Reduction | Excellent, year-round | None unless shutters are closed |
| Security Benefit | Constant, deters break-ins | None outside of storm season |
| Long-Term Value | Higher upfront cost, adds home value | Lower upfront cost, no added resale value |
How Much Do Impact Resistant Windows Cost?
Pricing depends on frame material, glass thickness, window size, and how many windows you are replacing. Here is a general cost range homeowners can expect per window, installed.
| Frame Type | Typical Cost Range (Per Window, Installed) | Notes |
|---|---|---|
| Vinyl | $650 – $1,100 | Best value for most homes |
| Aluminum | $800 – $1,400 | Strong, slim frames for larger openings |
| Fiberglass | $1,000 – $1,800 | Highest durability, lowest long-term maintenance |
| Wood-clad | $1,200 – $2,200 | Premium look, higher upkeep |
Other factors that affect your final price include:
- Total number of windows and total glass square footage
- Custom shapes or oversized openings
- Removal and disposal of old windows
- Local permitting fees required by Florida building code
- Any structural repairs needed around existing window openings
Common Mistakes Homeowners Make When Choosing Impact Windows
- Choosing the lowest price without checking the DP rating or NOA approval
- Assuming all laminated glass windows meet Florida code — some are only rated for other states
- Skipping a written proposal that lists frame material, glass thickness, and warranty terms
- Hiring a contractor who is not licensed or insured for window installation in your county
- Forgetting to confirm the permit process is included in the project
- Not asking whether the installation itself carries a separate labor warranty

Complete Your Home's Storm Protection: Windows and Roofing Together
Impact windows protect your walls and openings, but a home is only as strong as its weakest point. A wind-rated roof works with your new windows to keep pressure, water, and debris out of every part of your house during a storm.
If your roof is aging or was never rated for Florida wind speeds, it is worth reviewing our Metal Roofing in Oakland Park, FL services alongside your window upgrade. Replacing both at the same time can also simplify permitting and may qualify your home for a stronger wind mitigation insurance discount.
