Florida Window and Door

Why Florida Windows and Doors Are Different From the Rest of the Country

Florida is not like any other state in America when it comes to windows and doors. The combination of intense hurricane seasons, scorching heat, high humidity, and strict building codes means that every Florida homeowner must think carefully about the windows and doors they choose.

At Assured Contracting, LLC, we have helped hundreds of Central Florida homeowners navigate the complicated world of Florida window and door products. This guide will walk you through everything you need to know — in plain, simple English.

Whether you are building a new home, replacing old windows, or trying to prepare for the next hurricane season, this guide is for you.

Understanding Florida's Unique Window and Door Requirements

Florida sits in the most hurricane-prone region of the United States. The Florida Building Code (FBC) is one of the strictest in the country, and for good reason. Every year, storms test the limits of homes across the state.

Here is what makes Florida window and door requirements so different:

Florida Building Code (FBC) — What It Means for You

The Florida Building Code requires all new windows and doors to meet specific wind resistance standards. These vary based on where you live in Florida.

• High-Velocity Hurricane Zones (HVHZ): Miami-Dade and Broward counties have the strictest requirements
• Non-HVHZ regions (including Central Florida): Must meet FBC Chapter 14 requirements
• Impact resistance: Products must be tested and approved for wind-borne debris

If your home was built before 2002, there is a good chance your windows and doors do not meet today's codes. This matters for safety, insurance, and resale value.

Wind Speed Zones in Central Florida

Central Florida falls into wind speed zones typically ranging from 100 to 140 mph. This means your windows and doors must be engineered to handle these forces — not just rain and wind, but flying debris moving at highway speeds.

Impact Windows vs. Regular Windows — The Big Decision

This is the question we hear most often from Florida homeowners. Should you get impact windows or stick with regular windows and use storm shutters?

Let's break it down honestly.

What Are Impact-Resistant Windows?

Impact windows (also called hurricane windows or impact glass) have two layers of glass bonded to a strong PVB (polyvinyl butyral) or SGP (SentryGlas) interlayer. Think of it like car windshield glass — when it breaks, it holds together instead of shattering into dangerous shards.

They are designed to:

• Withstand wind speeds up to 200 mph
• Stop flying debris from penetrating your home
• Stay in the frame even after impact
• Protect against pressure changes that can cause roof failure

Impact Windows vs. Storm Shutters — Comparison

The bottom line: impact windows cost more upfront but deliver more value over time. For most Central Florida homeowners who plan to stay in their home for 5+ years, impact windows are the smarter choice.

Energy Efficiency: How the Right Florida Window and Door Saves You Money

Florida homeowners run their air conditioning for 9–10 months out of the year. That is a massive energy expense. The right Florida window and door choices can cut your cooling costs by 25–30% or more.

Here is what to look for on the energy label:

Key Energy Ratings Explained Simply

• U-Factor: Measures how well a window keeps heat out. Lower is better. Look for 0.30 or lower in Florida.
• Solar Heat Gain Coefficient (SHGC): Measures how much solar heat comes through. For Florida, look for 0.25 or lower.
• Visible Transmittance (VT): How much light comes through. Higher means brighter rooms.
• Air Leakage (AL): How much air sneaks through gaps. Lower is better.
• ENERGY STAR Certification: Look for the ENERGY STAR label — it means the product meets federal energy efficiency guidelines for your climate zone.

Low-E Glass — The Game Changer for Florida Homes

Low-E (Low Emissivity) glass has an invisible metallic coating that reflects heat. In Florida, this means solar heat stays outside while natural light still comes in. Most quality Florida window and door products now include Low-E glass as standard.

On a typical Central Florida home, upgrading from single-pane windows to Low-E impact windows can save $300–$600 per year on energy bills. Over 20 years, that adds up to $6,000–$12,000 in savings.

Storm Protection: What Actually Works in a Florida Hurricane

Not all storm protection products are created equal. Here is what you actually need to know to protect your Central Florida home.

The Weak Link: Your Windows and Doors

Structural engineers call windows and doors the "envelope" of your home. When a hurricane or severe storm breaks through this envelope, the pressure change can literally lift your roof off. This is why Florida window and door upgrades are so critical — not just for the glass itself, but for your whole home's survival.

What to Look For in Storm-Rated Products

1. Florida Product Approval Number: Every compliant product has one. Verify at floridabuilding.org.
2. Design Pressure (DP) Rating: The higher, the stronger. For Central Florida, look for DP+50 or higher.
3. Impact Rating: Must pass the large missile impact test (a 9 lb. 2x4 fired at 50 ft/sec) for full compliance.
4. Frame Material: PVC/vinyl and aluminum frames with reinforced corners handle Florida's humidity and heat best.
5. Proper Installation: Even the best window fails if not installed correctly. Always use a licensed Florida contractor.

Doors: The Overlooked Weak Point

Most homeowners upgrade their windows and forget about doors. But a standard residential door is not designed to handle hurricane-force winds. Here is what Central Florida homes need:

• Impact-rated entry doors — steel or fiberglass with reinforced cores
• Multi-point locking systems — spread the load across the entire door frame
• Impact-rated sliding glass doors — the most vulnerable opening in most Florida homes
• Garage doors — the largest single opening; must be wind-rated or braced

Florida Window and Door Products: Types and What They're Best For

Window Types for Florida Homes

• Single-Hung and Double-Hung Windows: Classic look, easy to clean, good for bedrooms and living rooms. Most common in Central Florida residential homes.
• Casement Windows: Crank open outward. Excellent seal when closed — great for energy efficiency. Good for kitchens and hard-to-reach areas.
• Sliding Windows: Wide and low-profile. Great for wide openings. Popular in Florida ranch-style homes.
• Picture/Fixed Windows: No moving parts — maximum energy efficiency. Best for views and areas where ventilation is not needed.
• Bay and Bow Windows: Adds square footage and light. Requires careful structural and impact detailing.
• Awning Windows: Hinged at top, open outward. Can stay open during light rain — good for Florida afternoon showers.

Door Types for Florida Homes

• Fiberglass Entry Doors: Best overall for Florida. Does not warp, rust, or rot. Excellent impact ratings. Energy efficient.
• Steel Entry Doors: Very strong and affordable. Can rust if the finish is damaged — needs regular maintenance in Florida humidity.
• Impact Sliding Glass Doors: Must be specifically impact-rated. Look for multi-point locks and reinforced frames.
• French Doors: Elegant but require both panels to be impact-rated. More complex installation.
• Folding/Bi-fold Glass Doors: Luxury option for indoor-outdoor living. Requires premium impact hardware.

How Florida Windows and Doors Affect Your Home Insurance

This section could save you thousands of dollars. Florida homeowners insurance is expensive — and the type of windows and doors you have directly affects your premium.

Insurance Discounts Available to Florida Homeowners

• Wind Mitigation Inspection: A licensed inspector evaluates your home's wind resistance, including your windows and doors. A good report can reduce your premium by 10–45%.
• Opening Protection Credit: This is the specific credit for having compliant impact-rated windows and doors. It is one of the largest single discounts available.
• Roof-to-Wall Connection Credit: Often tied to window/door upgrades as part of a full wind mitigation package.

How to Get the Most from Your Insurance

1. Upgrade to impact-rated windows and doors.
2. Get a wind mitigation inspection (cost: $75–$150, saves you hundreds per year).
3. Submit the report to your insurance company.
4. Shop your policy with the new report — rates vary widely between insurers.

Assured Contracting, LLC can help coordinate wind mitigation inspections for Central Florida homeowners after installation.

The Connection Between Your Windows, Doors, and Your Roof

Most homeowners do not realize how closely connected their windows, doors, and roof actually are. When hurricane winds find an opening — a broken window, a failed door — the pressure buildup inside your home can literally blow off your roof.

This is why at Assured Contracting, LLC, we take a whole-home approach to storm protection. Windows and doors are your first line of defense, but they work together with your roof system.

If you are looking at Florida window and door upgrades, you should also evaluate the condition of your roof. Learn more about Roof Repair in Central Florida and how a comprehensive approach to storm protection can save you money and stress.

Common roof issues that compound window and door problems:

• Aging or damaged roofing allows water infiltration alongside window leaks
• Improperly sealed roof-to-wall connections reduce the effectiveness of even the best windows
• Storm damage to fascia and soffits can compromise window frame integrity

When Assured Contracting, LLC evaluates your home, we look at the full picture — not just the windows in isolation.

Common Mistakes Florida Homeowners Make With Windows and Doors

After working with hundreds of Florida homeowners, we have seen the same mistakes over and over. Here is how to avoid them.

Mistake 1: Buying Based on Price Alone

The cheapest window is rarely the best choice in Florida. A window that saves you $50 upfront but fails to meet current codes, leaks air, or needs replacement in 10 years costs you far more. Focus on total value — energy savings, insurance discounts, and longevity.

Mistake 2: Not Verifying Florida Product Approval

Not every window sold in Florida is actually code-compliant. Always ask for the Florida Product Approval number and verify it at floridabuilding.org. An uncertified window can result in a failed inspection, requiring costly removal and replacement.

Mistake 3: Hiring an Unlicensed Contractor

Florida requires window and door installers to be licensed. An unlicensed installation voids the product warranty, can fail inspection, and — most importantly — may not actually protect your home in a storm. Always verify your contractor's license at myfloridalicense.com.

Mistake 4: Ignoring the Frame and Installation

The glass in an impact window is only as strong as the frame holding it and the installation anchoring it to your home. Poor frame selection or improper anchoring is a common failure point. This is why professional installation matters as much as product selection.

Mistake 5: Forgetting About Doors

Many homeowners upgrade all their windows and leave a 30-year-old entry door or non-impact sliding glass door in place. A single weak opening can defeat the purpose of all your other upgrades.

Mistake 6: Not Getting Permits

Every window and door replacement in Florida requires a permit. This protects you legally, ensures the work is inspected, and is required for insurance purposes. Any contractor who suggests skipping the permit should raise an immediate red flag.

How to Choose the Right Florida Window and Door Contractor

Your contractor choice is as important as your product choice. Here is what to look for:

Credentials to Verify

• Florida State Contractor License (verify at myfloridalicense.com)
• General Liability Insurance — minimum $1 million
• Workers' Compensation Insurance
• References from Central Florida projects
• Experience with Florida Building Code inspections

Questions to Ask Any Contractor

1. Do you pull permits for every installation?
2. Can you provide the Florida Product Approval number for the products you recommend?
3. Do you provide a written, itemized estimate?
4. What is your warranty — both product and labor?
5. Have you worked with my HOA or local building department before?
6. Will you coordinate the wind mitigation inspection after installation?
