Every June, the same question starts showing up on our phone: do I need hurricane impact sliding glass doors, or is the slider I already have good enough? The honest answer depends on where your house sits, when it was built, and what you are trying to protect — your family, your insurance premium, or both.
Most of what homeowners read on this comes from companies that only sell whole new doors. So here is the version from a repair company: what an impact-rated slider actually is, how to check whether you already own one, when Florida code genuinely requires hurricane protection, and the maintenance problem that catches almost every impact door owner by surprise.
What makes a sliding glass door “hurricane impact” rated
An impact sliding glass door is not just thicker glass. Three things have to work together:
- Laminated glass. Two panes bonded to a clear plastic interlayer. When something hits it the glass can crack, but the interlayer holds the pieces in place so the opening is never breached.
- A reinforced frame. Heavier extrusions, deeper glazing pockets and stronger interlocks — glass that will not break is useless if the frame lets go.
- Real anchoring. The frame fastened into the structure to the manufacturer’s pattern. This is the step bad installs skip, and it is invisible once the trim goes on.
Products earn the rating by being tested, not advertised. A genuine impact unit has passed missile impact and cyclic pressure testing and carries either a Florida Product Approval number or a Miami-Dade Notice of Acceptance. If a salesperson cannot produce one of those numbers for the door they are quoting, it is not rated, whatever the brochure says.
Be clear about what the rating buys, though: impact does not mean indestructible. Hurricane impact sliding glass doors are designed to stay in the opening after a strike, not to come through a storm unmarked. A hit hard enough to spiderweb the glass still means a glass replacement afterward.
What you get is that the wind never gets inside and pressurizes the house, which is the failure that takes roofs off.
How to tell if you already have hurricane impact sliding glass doors
A surprising number of Central Florida homeowners already own impact glass and have no idea. Before you price anything, check:
- Look for the etched stamp. Most impact glass carries a small permanent etching in a bottom corner of the pane — manufacturer, standard, sometimes an approval number. Clean the corner and look at it in raking light.
- Look at the edge of the glass. Sight down the exposed edge of the moving panel. Laminated glass shows a faint seam where the interlayer sits between two lites; standard tempered glass has none.
- Try to move it. Impact panels are noticeably heavier. If your slider feels like furniture rather than a door, that is a clue.
- Check the age of the house. Florida’s statewide building code arrived in 2002 and got stricter after the 2004 storm season, so homes built or re-glazed since then are far more likely to have rated openings.
- Pull your permit history. Your county building department keeps records, and a window and door permit on file usually lists the product approval numbers.
If you find a rating, your money is better spent maintaining that door than replacing it.
Does Central Florida code require impact sliding glass doors?
For most inland Orlando-area homes, no — and this is where a lot of homeowners get oversold.
Florida requires opening protection inside mapped windborne debris regions. Those regions track design wind speeds, so they are strictest along the coast and in South Florida and ease inland.
Much of inland Orange, Seminole and Lake County sits outside the windborne debris region entirely, which means an existing home there generally is not required to have impact glass or shutters. New construction, coastal parcels and anything you permit as a replacement can be a different story, and the line does not follow county borders.
So verify rather than assume — one free call to your county or city building department with your address settles it. Not being required is not the same as not being worth it, though. Two reasons homeowners here choose impact anyway:
- Insurance. Florida insurers offer wind mitigation credits for protected openings, verified by a wind mitigation inspection. Whether the credit is meaningful depends entirely on your carrier, so ask your agent for the number in writing before you count on it.
- Not boarding up. Impact glass is always on — no plywood in the garage, no scramble two days before landfall. That matters if you travel or the house is a rental.
Impact doors vs. shutters, panels and film
Impact sliding glass doors are the most expensive way to protect a big opening, and not the only way:
- Accordion and roll-down shutters protect the same opening for less and are permanent. They change how the back of your house looks, and roll-downs have motors and tracks that need service.
- Corrugated metal or polycarbonate panels are the budget option. They work, but somebody has to install them before every storm and store them the rest of the year.
- Security film is the one to be careful with. Film on existing glass is not an approved substitute for opening protection under Florida code and will not earn a wind mitigation credit on its own. It deters burglars. It is not hurricane protection.
If your slider is otherwise in good shape, shutters over a healthy standard door often protect you for far less than an impact replacement.
The part nobody warns you about: impact doors are hard on rollers
This is the failure we get called out to most often on impact sliders, and nobody is told about it at the point of sale.
Laminated impact glass is heavy, and all of that extra weight rides on the same small tandem rollers at the bottom of the panel — in Central Florida, working in humidity, wind-blown grit and, near the coast, salt air. Builder-grade rollers under a standard panel fail in a handful of years.
Put an impact panel on them and they fail faster: the bearings flatten, the panel drags, and people assume their expensive new door is defective when it just needs proper rollers.
The good news is that this is a repair, not a replacement. Heavy-duty rollers sized for the panel weight are routine work, and you can see exactly what roller replacement costs before anyone comes out: $275 for most standard doors, $395 for oversized and high-end doors such as Andersen and PGT. Every part we install carries a two-year warranty.
The same logic applies to glass. If the sealed unit has fogged or cracked, replacing the glass rather than the whole door is very often the right call, and a much smaller job than a full impact retrofit.
Repair or replace before hurricane season? An honest take
Replace with impact if the frame is corroded through, the door has been broken into, you are already remodeling that wall, or your insurer has quoted a credit that makes the math work. Impact doors are a good product — just a big project, worth doing for the right reason rather than out of storm-season anxiety.
Repair what you have if the frame is sound and the complaint is that the door drags, sticks, leaks, rattles or will not lock.
Those are roller, track, weatherstripping and lock problems — and they are also the problems that make a door fail in a storm, because a slider that will not close and latch properly is a weak opening no matter what the glass is rated for.
Do this yourself: vacuum out the bottom track, check that the latch fully engages the keeper, and look for daylight around the perimeter. Call somebody for: lifting panels out, roller replacement, anything involving glass. An impact panel is heavy enough to hurt you, and a dropped one is an expensive mistake in a doorway you cannot leave open overnight.
Sort this out now, in the quiet weeks, rather than the day a cone shows up on the news. Most of what we do is finished in a single visit; if your door needs a special-order part, we tell you up front rather than after we have taken it apart.
Frequently asked questions
Are hurricane impact sliding glass doors worth it in Orlando?
For inland Orlando homes they are usually optional rather than required, so it comes down to insurance credits and convenience. Get your carrier to quote the credit in writing and check with your building department first — if the credit is small and your current door is healthy, shutters or a good repair often make more sense.
Can you tell if glass is impact rated just by looking at it?
Usually yes. Look for a permanent etched stamp in a bottom corner of the pane, and sight down the exposed edge of the moving panel for the thin seam that shows a laminated interlayer. Weight is the other giveaway — impact panels are much heavier than standard ones.
Does impact glass stop a door from leaking or sticking?
No. Impact rating is about the glass and frame surviving a strike. Leaks come from clogged weep holes and failed weatherstripping, and sticking comes from worn rollers and dirty tracks. An impact door needs the same maintenance as any other slider, and its extra weight makes roller wear worse.
Can the glass in an impact door be replaced on its own?
Sometimes. It depends on how the panel is built and whether the unit has to be matched to the door’s product approval. It is worth asking before you accept a quote for a whole new door — call us with the door in front of you and we will tell you honestly which way it goes.
Should I replace my sliding door before hurricane season or just repair it?
If the frame is sound, repair. A door that closes, latches and seals correctly is a far stronger opening than a neglected one, and roller, track and lock work is finished quickly. Save replacement for a corroded frame or a genuine remodel.
