How Entry Door Failure Destroys a Home

The sequential chain of destruction when a non-rated door fails during hurricane conditions

T+0 Seconds
Initial Door Breach

Hurricane-force winds find the weakest point. Non-rated door frame separates or glass sidelights shatter. Entry point compromised.

1
T+3 Seconds
Rapid Pressurization

Wind rushes into home at 150+ mph. Interior pressure spikes by 50+ PSF. Windows bow outward, ceiling drywall lifts.

2
T+8 Seconds
Secondary Failures

Rear windows blow out. Interior doors fail. Garage door buckles from internal pressure. Water infiltration begins.

3
T+15 Seconds
Roof Uplift Begins

Internal pressure lifts roof deck. Sheathing separates at weakest connections. Wind and rain enter attic space.

4
T+30 Seconds
Catastrophic Loss

Partial or complete roof failure. Contents exposed to elements. Structure becomes total loss. All from one failed door.

The Data Behind Door Failure

Comparing outcomes between homes with and without impact-rated entry doors

⚠

Non-Rated Door Outcomes

  • 73% of major interior damage linked to entry failure
  • Average repair cost: $67,400 (vs $8,200 with rated)
  • 8x higher likelihood of roof damage cascade
  • Contents loss rate: 45% of home value
  • Displacement time: 4-8 months average
  • Insurance claim disputes: 3x more common
✓

Impact-Rated Door Outcomes

  • Building envelope maintained in 98% of events
  • Average repair cost: $8,200 (exterior only)
  • Interior damage limited to minor water intrusion
  • Contents protected in 95% of cases
  • Displacement time: 0-2 weeks typical
  • Insurance premium discount: 15-25%
Florida Building Code 2024

Broward Entry Door Requirements

Mandatory specifications for HVHZ compliance

📋

Wind Pressure Rating

FBC 2024 Section 1626

Entry doors must withstand design wind pressures based on:

Exposure Category C or D

Risk Category II minimum

Typical requirement: +75/-90 PSF for coastal Broward locations with 180 mph design wind speed.

🎯

Impact Testing Protocol

TAS 201, 202, 203

Large missile impact testing required:

9-lb 2x4 @ 50 fps

Door must remain in frame and operable after impact. Cyclic pressure testing follows with 9,000 cycles at design pressure.

🔒

Hardware Requirements

AAMA/WDMA/CSA 101

Multi-point locking system with:

Minimum 3 engagement points

Hinges rated for 400 lb minimum door weight. Reinforced strike plates with 3" screws into framing.

📜

Product Approval

Miami-Dade NOA Required

Doors must have current Notice of Acceptance:

Miami-Dade County NOA

Or Florida Product Approval with HVHZ designation. Installation per manufacturer specifications with engineer-sealed shop drawings.
