Impact Doors vs Regular Doors: Complete Comparison
Compare impact doors to regular doors for your Florida home. Learn about protection levels, energy efficiency, security, and what Miami-Dade code requires.
Your doors are the largest openings in your home — and the most vulnerable during a hurricane. Here's why upgrading to impact doors is essential in South Florida.
Why Doors Matter Most
During a hurricane, if a single large opening fails, the sudden pressure change inside your home can blow off the roof. Entry doors, sliding glass doors, and garage doors are the biggest openings and therefore the highest-risk points.
Impact Doors vs Regular Doors
Entry Doors
| Feature | Regular Door | Impact Door |
|---|---|---|
| Hurricane Protection | None | Category 5 rated |
| Forced Entry Resistance | 1-2 kicks | 20+ minutes |
| Energy Efficiency | Poor (gaps, thin panels) | Excellent (sealed, insulated) |
| Sound Reduction | Minimal | 35-40 STC |
| Code Compliant (HVHZ) | ❌ | ✅ |
| Average Cost | $300-800 | $2,000-5,000 |
Sliding Glass Doors
Sliding glass doors are particularly vulnerable because of their large glass area. Impact sliding doors use the same laminated glass technology as impact windows but in heavy-duty aluminum track systems.
- Regular sliding door: A Category 1 hurricane can shatter it
- Impact sliding door: Withstands Category 5 and large missile impact
French Doors
Impact French doors combine the elegance of traditional French doors with full hurricane protection. They feature reinforced multi-point locking systems and laminated glass panels.
The Garage Door Factor
Many homeowners forget about their garage door — the single largest opening in most homes. An unprotected garage door can fail under wind pressure, causing catastrophic structural damage.
Options:
- Impact-rated garage door: Full hurricane protection
- Garage door bracing kit: Budget-friendly reinforcement
- Wind-rated garage door: Lighter protection for non-HVHZ areas
Code Compliance in Florida
In the HVHZ zone (Miami-Dade and parts of Broward County), ALL doors must be impact-rated or protected by approved shutters. This includes:
- Front entry door
- Back entry door
- Sliding glass doors
- French doors
- Garage doors
