Quick summary

Missing a storm panel? One got bent or cracked after the last storm? Found a house with tracks but no panels? You're not alone — storm panels are the most commonly lost and damaged form of hurricane protection because they're stored and moved rather than permanently installed. Here's how to get the right replacement.

Step 1 — Identify Your Panel Type

Before you order anything, identify exactly what you have. Storm panels come in three main materials:

Type	Appearance	Weight	Cost to Replace
Aluminum	Silver/grey corrugated metal	Heavy	$8–$15/sq ft
Steel	Heavier, often thicker than aluminum	Heaviest	$10–$18/sq ft
Polycarbonate	Clear/translucent corrugated plastic	Light	$14–$22/sq ft
Fiberglass	Opaque white/cream corrugated	Medium	$12–$20/sq ft

Look for a sticker or stamp on the panel itself — most manufacturers stamp the panel with their name, product approval number, and panel dimensions. This is the most reliable way to find an exact match.

Step 2 — Measure the Opening

Storm panels are cut to fit specific openings. To get the right size replacement:

Measure the track span — measure the distance between the inside edges of the top and bottom tracks (or left and right for vertical-install systems)
Measure panel height — measure the distance from the bottom of the top track slot to the top of the bottom track slot
Count the corrugations on an existing panel — panels are typically sized to fit a specific number of corrugations in the track
Note the overlap — adjacent panels overlap by one corrugation. Account for this in your replacement order

When in doubt, bring an existing panel with you to the supplier — they can match it exactly.

Where to Buy Replacement Panels

In order of preference:

Original installer — if you know who installed your system, call them first. They likely still stock the same product and can cut panels to your exact size
Local shutter suppliers — most coastal markets have wholesale shutter supply companies that sell direct to homeowners. Search "[your city] hurricane panel supplier"
Home Depot / Lowe's — stock standard aluminum panels in some coastal store locations, especially in Florida and Texas. Selection is limited but useful for emergency replacement
Online suppliers — panel suppliers like ShutterSupply.com, CoastalContractorSupply.com ship to most coastal states. Lead time is typically 1–2 weeks
Manufacturer direct — if you have the manufacturer name from the panel stamp, contact them for local dealer referrals

How to Install a Replacement Panel

Installing a single replacement panel is straightforward if the tracks are in good condition:

Clean the tracks — remove any debris, rust, or corrosion from the top and bottom channels
Slide the replacement panel into the top track first — the top track is deeper to allow the panel to clear the bottom track
Lower the panel into the bottom track
Slide the panel to overlap correctly with adjacent panels — one corrugation overlap is standard
Install fasteners per the original product approval — wing nuts, bolts, or clips depending on your system

If the tracks are damaged, bent, or corroded, track replacement requires a licensed contractor — do not try to work around damaged tracks as it can void the product approval and leave protection gaps.

When to Replace the Whole System

Consider replacing the entire storm panel system rather than individual panels if:

More than 30–40% of panels are missing or damaged
Tracks are corroded, bent, or pulling away from the wall
The product approval number on your panels is no longer valid for current wind zone requirements
The panels are steel and you're in a coastal corrosion zone — aluminum is much better suited for salt air environments
You're considering upgrading to a permanent system like accordion shutters

Use our cost calculator to compare replacement panel costs versus upgrading to accordion shutters — the upgrade often makes financial sense when you factor in convenience and insurance savings.

Biloxi, Mississippi — The Missing Panels Before Nate

Hurricane Nate made landfall near Biloxi on October 8, 2017 as a Category 1 storm. Thomas had owned his home in D'Iberville for 12 years and had an aluminum storm panel system on all windows. In the days before Nate, he retrieved the panels from his garage storage shed and began mounting them — only to discover that six panels were missing. Two more were bent and wouldn't slide into the tracks.

Thomas had last deployed the panels before Hurricane Isaac in 2012 — five years earlier. In the intervening years, panels had been lent to a neighbor, lost when the storage shed was reorganized, and bent when yard equipment fell against them. He had no idea. Nate tracked directly over the Coast as a Category 1, producing 90 mph gusts. Three windows on his east exposure, which couldn't be covered, cracked.

Replacement cost for the cracked windows: $2,800. Fabricating six new matching aluminum panels: $620. 'I had a complete panel system,' Thomas said. 'I just hadn't inventoried it since the Obama administration.'

What this means for your home: Storm panels require an annual inventory before storm season — not the day before a storm. Count every panel, test every track, and replace missing or damaged panels in the off-season when fabricators have lead time. A panel that isn't there when you need it is identical to no panel at all.

Corpus Christi, Texas — The Track Without the Panels

When Karen bought her Corpus Christi home in 2019, the seller disclosed 'hurricane panel tracks on all windows' — which Karen interpreted as a complete storm panel system. The tracks were indeed installed on every window. The panels were not included in the sale, stored somewhere the seller had taken with them, or had been discarded.

Karen discovered this on June 3, 2020 when Tropical Storm Cristobal prompted a tropical storm watch for the Corpus Christi area. She went to the garage looking for the panels that weren't there. She called three local suppliers. Two couldn't cut custom panels in less than 10 days. The third could deliver standard-width panels in 48 hours, but they were the wrong profile for her track system.

Karen boarded with plywood — a process that took most of the available preparation time and left several second-floor windows unprotected. Cristobal passed without significant damage, but Karen had learned the lesson. She spent $1,400 on a correctly-fabricated panel set the following month. 'Tracks without panels is like having a gun without bullets,' she said.

What this means for your home: When purchasing a home with storm panel tracks, verify that panels exist, that they fit the specific tracks, and that there is enough overlap hardware, fasteners, and clips for a complete deployment. Ask for a demonstration before closing. If panels are missing, negotiate a credit equal to the fabrication cost — typically $800–$1,500 for a standard home — before the sale closes.

New Bern, North Carolina — Hurricane Florence Panel Damage

Hurricane Florence made landfall near Wilmington, North Carolina on September 14, 2018 and stalled, producing catastrophic rainfall and prolonged 60–80 mph winds across the entire coast. Richard had polycarbonate storm panels on his New Bern home — a system installed in 2015 that he had deployed successfully before two previous storms.

During Florence's extended duration, two panels on the south exposure buckled under the sustained wind pressure — not cracking, but deforming enough to create gaps at the edges where they met adjacent panels. Wind-driven rain entered through the gaps and saturated the interior of two rooms. Damage totaled $11,200.

Post-storm inspection found that the panels had been stored improperly between deployments — stacked flat on the garage floor with weight on top of them — which had induced a warp that reduced their effective stiffness. The panels were still technically usable but had degraded. Richard hadn't noticed because he had never closely inspected them between storms. He replaced the entire panel set ($2,400) and built a proper vertical storage rack.

What this means for your home: Polycarbonate panels can warp when stored improperly, particularly if stacked flat with weight or in high-heat environments like unshaded garage storage. Store panels vertically or hung from wall brackets. Inspect panels annually for warping, yellowing, and brittleness. A panel that looks intact may have lost significant structural strength from UV exposure or improper storage.

FAQ

Frequently Asked Questions

Can I mix panel brands or materials?

Technically no — mixing brands or materials can create gaps in protection, compromise the product approval, and fail a building inspection. The entire panel system needs to carry a consistent product approval. If you can't find matching panels, a full system replacement is the safer option.

My tracks are there but all the panels are gone. What do I do?

Measure your tracks and openings carefully and take photos. Contact local shutter suppliers with your measurements — most can cut panels to fit existing tracks as long as the track style is standard. Bring a photo of the track profile to the supplier.

How long do aluminum storm panels last?

In a non-coastal environment, aluminum panels can last 20–30 years. In a salt-air coastal environment, 10–15 years is more realistic before corrosion becomes a problem. Polycarbonate panels are more corrosion-resistant but can yellow and become brittle with UV exposure after 10–15 years.
