Impact glass or hurricane shutters

The question behind both products is the same, and it is worth stating plainly because the marketing rarely does. The danger to a house in a severe storm is not broken glass. It is what happens after an opening fails: wind gets inside a sealed building, pressurizes it, and starts pushing outward on the roof and walls at the same time the storm is pushing inward. Protecting openings is about keeping the building sealed.

What each one is

Impact glazing is laminated glass in a tested frame. Two sheets of glass are bonded to a tough interlayer, so when the outer sheet breaks the fragments stay stuck to the interlayer and the opening stays closed. The assembly is certified by firing a timber missile at it and then cycling wind pressure thousands of times on the already-damaged unit.

Shutters are a separate barrier fitted over the outside of an existing window. They come as accordion units that fold out from the sides, roll-downs, panels that bolt into permanent tracks, and fabric screens. The window behind them can be anything, including the original aluminum single-hung.

Cost

Shutters are the cheaper route per opening, sometimes dramatically so, and they can be added to windows you already own. Impact glazing costs roughly double a standard replacement window, and the national figures put an installed hurricane-rated unit near $1,250 against about $800 for a comparable standard one.

The comparison is only fair when you are honest about what each buys. Shutters protect openings. Impact windows protect openings and replace the windows, which on a house full of forty-year-old aluminum frames is two purchases in one. If the windows need doing anyway, the marginal cost of impact rating is far smaller than the sticker difference suggests.

Deployment, which is the real difference

Shutters have to be put up. Accordion and roll-down units are quick, a few minutes per opening. Removable panels are not: they have to be stored somewhere, carried out, lined up and bolted on, and then taken down and stored again afterward. In a season with several near-misses that happens more than once.

The problem is not the effort so much as the availability. Shutters protect a house only when somebody is there to deploy them. A house that is empty, a homeowner who is travelling, an owner who cannot safely work outdoors on a ladder, and the protection does not exist. Impact glass works whether or not anyone is home, which for a lot of people is the entire argument.

Daylight and living with it

Shutters put a house in the dark. A closed-up home with panels over every opening is unpleasant for the days a storm takes to pass, and if the power is out it is worse. Impact glass leaves the house looking like a house.

There is also a year-round difference nobody buys for and everybody notices. The laminated interlayer damps sound, so road noise drops measurably, and it blocks the large majority of ultraviolet light, which slows the fading Florida sun inflicts on floors and furniture. Shutters do neither, because they are only there a few days a year.

Insurance

Florida law requires insurers to reflect wind mitigation features in their rates, and opening protection is one of the features on the state's uniform inspection form. Both impact glazing and approved shutters qualify. What matters is that the protection is documented and that it covers all the openings, since partial protection generally does not earn the credit. The wind mitigation guide covers what the inspector looks at and what paperwork to keep.

What the code requires in Deltona

Neither, in all likelihood. The Florida Building Code requires impact-resistant glazing or approved shutters inside the wind-borne debris region, which is defined by the wind speed map: within one mile of the coastal mean high water line where the ultimate design wind speed reaches 130 mph, or anywhere it reaches 140 mph, for ordinary homes. Deltona is more than fifteen miles inland, so the coastal trigger does not apply, and whether the higher-speed contour reaches a given parcel is a question for the wind speed mapping Volusia County publishes and for the city Building Division.

What the code does require, everywhere in the state, is that the window meet the design pressure calculated for its position on the building. That is a structural requirement about wind load and it is not the same thing as impact rating. A Deltona house can be entirely code compliant with no opening protection at all and still need every window rated for pressure.

That is worth knowing before a sales conversation, because "code requires it" is a claim you can check. It also reframes the decision honestly: in Deltona, opening protection is usually an elective purchase made for insurance, peace of mind and the storms that reach this far inland, and both 2022 and 2024 supplied reminders that they do.

A reasonable way to decide

• If the windows are old and being replaced anyway, price impact rating as an upgrade rather than a separate product. The marginal number is what matters.
• If the windows are newer and sound, shutters protect them for less than replacing them.
• If the house is ever empty during the season, weight availability heavily. Protection you have to be present to deploy is protection some of the time.
• If budget forces a partial job, do the biggest opening first. That is almost always the patio slider.
