What's the real difference between "impact windows" and "hurricane windows"?

In the trade those terms usually mean the same thing — windows built with laminated glass that stays intact under direct impact, tested and rated under Florida's building code. Some people also use "hurricane windows" more loosely to include a standard window paired with code-approved shutters or panels, which is a different, often lower-cost approach that still meets code. Either path can be compliant; what matters is that the whole opening, glass or shutters, carries the right rating.

What should I ask a contractor before they install new-construction windows on my Coquina Key build?

Ask for their state contractor license number, proof of liability and workers' comp insurance, and examples of recent new-construction — not just replacement — window work in Pinellas County. Ask specifically how they handle rough-opening verification and fastening schedules for impact-rated product, since that's where corners get cut. A contractor who answers those questions specifically, rather than in general terms, usually does this kind of work regularly.

Do I have to use laminated impact glass on every window, or can I use shutters instead?

Florida code gives you both options in the wind-borne debris region: impact-rated glazing on the window itself, or standard glazing protected by code-approved shutters or panels on every opening. Impact glass costs more up front but needs no action before a storm and keeps the view unobstructed; shutters cost less initially but have to be deployed and maintained so they still work years later. We'll walk you through both so you can weigh the trade-off for your build.

What does a window's Design Pressure (DP) rating actually mean?

The DP rating is the tested amount of positive and negative wind pressure a window can withstand without failing, tied to its Florida Product Approval or Miami-Dade NOA. Higher elevations, corner openings, and larger sizes generally need a higher DP rating than a small, sheltered window on the ground floor. Your plans examiner checks that every ordered window's DP rating matches what the engineered plans require for its exact spot on the house.

Does Coquina Key's flood zone affect what windows I can install?

It can affect sill heights and how low a window can sit relative to base flood elevation, which is a separate check from the wind rating but reviewed at the same time during permitting. We coordinate window selection with your architect or GC's elevation certificate so sill heights and product approvals line up on the first submittal instead of getting flagged during plan review.

New-Construction Windows in Coquina Key, St. Petersburg

Building New in Coquina Key Puts Extra Demands on Your Windows

Coquina Key is a canal-front peninsula on the south side of St. Petersburg, and that location changes what a new-construction window package needs to do. Homes here sit close to open water, with wide sightlines and long exposure to wind, salt spray, and sun that a house a few miles inland doesn't deal with in the same way. If you're framing a new home or a major addition on the Key, the windows aren't a finishing touch you pick from a catalog at the last minute — they're part of the structure, part of the building envelope, and part of what keeps water and wind out during the storms that Pinellas County sees every hurricane season.

Three things drive almost every decision on a new-construction window package here: wind, water, and sun. Hurricane-force wind and the wind-driven rain that comes with it test the seal and the anchoring long after the storm passes. Year-round Florida UV breaks down cheap vinyl, gaskets, and low-quality glazing seals faster than in most of the country. And salt air off the bay corrodes hardware and fasteners that aren't rated for a marine-adjacent environment. New-construction windows give you one real chance to get all three right before drywall, stucco, and trim close in around them.

What Florida Building Code Requires Before the Windows Ever Arrive

The Wind-Borne Debris Region

St. Petersburg sits inside Florida's wind-borne debris region, which means new-construction openings generally need either impact-rated glazing or code-approved shutters or panels on every opening, not just a few. This isn't a matter of preference — it's what the plans examiner checks before framing is signed off, and it's what keeps a window from becoming a hole in the wall the moment something hits it during a storm.

Design Pressure and Product Approval

Every window on a new build also has to carry a Florida Product Approval (or Miami-Dade NOA) number and a design pressure (DP) rating that matches its size, location on the house, and exposure. A window on a corner of a two-story elevation facing open water typically needs a higher DP rating than the same size window tucked on a sheltered wall. Getting this wrong doesn't just risk a failed inspection — it can mean re-ordering windows mid-build, which is the single most common schedule delay we see on coastal new construction.

Coordinating With the Plan Set

On new construction, window selection isn't a standalone decision — it has to match the schedule of openings on the engineered plans, opening by opening. We cross-check every size, elevation, and DP requirement against the plan set before anything is ordered, so what shows up on the truck is what the inspector expects to see, not something that has to be explained or substituted at the last minute.

Choosing a Frame and Glass Package That Will Actually Last on the Water

Frame material matters more on Coquina Key than it does a few miles inland, mostly because of salt air corrosion and constant UV exposure. Here's how the common options stack up for a new build in this location:

Frame Material	Salt-Air / Corrosion Behavior	Impact Options	Typical Fit
Vinyl (impact-rated)	Won't corrode; UV-stable formulations hold up well, cheaper vinyl can chalk and warp over years in full sun	Widely available in laminated-glass impact packages	Most new-construction budgets; good value if the vinyl is a quality, UV-stabilized product
Aluminum	Needs a marine-grade finish; untreated or poorly coated aluminum can pit and corrode near the water	Common in larger impact-rated sliders and picture windows	Larger openings and contemporary designs where a narrow sightline matters
Fiberglass	Very stable in heat and salt air, with minimal expansion and contraction	Available impact-rated, fewer size options than vinyl	Owners who want the lowest long-term maintenance and are building for the long haul

Glass matters as much as the frame. On new construction we spec laminated glass — two panes bonded around an interlayer — for impact resistance, paired with a Low-E coating tuned for Florida's heat and glare rather than for a colder climate. The right coating cuts the west-facing afternoon heat load on a water-facing room without turning the glass dark or reflective in a way that doesn't suit the house.

What a Correct New-Construction Installation Involves

New-construction installs happen before stucco and trim go on, which is both the advantage and the risk. Done right, the window becomes a sealed, flashed, structurally anchored part of the wall assembly. Done wrong, the mistake gets buried and doesn't show up until the first wind-driven rain event, sometimes years later.

A correct install, in order, looks like this:

Rough opening checked against the window's actual approved dimensions before it's framed tight, with tolerance left for shimming.
Sill pan flashing installed so any water that gets past the glazing drains back out, not into the wall cavity.
Window set plumb, level, and square, then anchored using the fastener type, spacing, and embedment called out on that specific product's Florida Product Approval — not a generic fastening schedule.
Flashing tape and sealant compatible with both the window's frame material and the wall's water-resistive barrier, lapped correctly so water always sheds outward and down.
Stucco or siding trades briefed on where the window's nailing flange sits so their finish doesn't bridge or trap moisture against it.

That fastening step is where we see the most corner-cutting from crews who don't work impact-rated products regularly. The product approval documentation specifies an exact screw type, length, and spacing for a reason — it's what the design pressure rating was tested with. Swap in whatever fastener happens to be on the truck that day and the window may look identical but no longer perform to the rating it's certified for.

How We Work With Builders and Owner-Builders on Coquina Key

Most of our new-construction work here comes in one of two ways: as part of a general contractor's crew on a full build or major renovation, or directly with an owner-builder managing their own trades. Either way, the process is the same:

Plan review: we take off every opening from the architectural plans, checking sizes, elevations, and any that face open water or sit on a corner condition needing a higher DP rating.
Product selection: we walk through frame material, glass package, and grid or design options against your budget and the house's exposure, not a one-size-fits-all recommendation.
Ordering and lead times: impact-rated product runs longer lead times than stock windows, especially in larger sizes — we build that into the schedule with your GC up front so it doesn't hold up framing.
Pre-install verification: we check rough openings against the actual windows before they're set, catching framing errors while they're still cheap to fix.
Install and inspection: windows go in following the fastening and flashing sequence above, ready for the building department's inspection without rework.

What New-Construction Windows Cost in a Coastal Build

Costs vary by opening size, frame material, and how many openings are large-format or corner units, but here's what typically moves the number on a Coquina Key build:

Cost Factor	Why It Matters
Design pressure rating	Higher-DP windows for exposed or upper-floor openings cost more than the same size at a lower rating
Frame material	Vinyl is generally the entry point; aluminum and fiberglass run higher depending on size and finish
Glass package	Laminated impact glass with a tuned Low-E coating costs more than clear glass but is required in the wind-borne debris region
Opening size and shape	Large sliders, picture windows, and custom shapes cost more per square foot than standard operable sizes
Number of openings	A whole-house new-construction order has better per-unit pricing than ordering piecemeal later

We give a written, itemized quote before anything is ordered, broken down by opening, so you can see exactly what's driving the number rather than a single lump-sum figure.

Impact Windows and Your Homeowners Insurance

On new construction, impact-rated windows aren't just a code requirement — they typically factor into your wind mitigation inspection, which Florida insurers use to help set homeowners insurance premiums. Opening protection (impact glass or approved shutters covering every exterior opening) is one of the categories a wind mitigation inspector checks, and covering every opening consistently, rather than upgrading only some, is usually what qualifies a home for the full credit. Ask your insurance agent what documentation they'll want once the build closes out. Keeping copies of the product approval labels and the final inspection paperwork from your window install makes that conversation easier, whether it's for your first policy or a future re-inspection.

Mistakes We See on Coastal New Builds — And How to Avoid Them

Most window problems on new construction trace back to a short list of avoidable mistakes. Before your rough openings are framed, it's worth confirming with your GC or window contractor that:

Windows are ordered only after rough openings are field-verified, not straight off the architectural plans, to avoid gaps that get over-shimmed or openings that need re-framing.
The fastening pattern used is the one specified in that product's Florida Product Approval, not a generic pattern used across every job.
Sealant and flashing tape are compatible with the specific frame material — the wrong combination can fail to bond or degrade faster in direct sun.
The design pressure rating matches what the elevation actually calls for, rather than a lower rating chosen to save money up front.
The window crew and the stucco or siding trade have coordinated, so the finish sheds water away from the frame instead of trapping it.

Why Local Experience in St. Petersburg and Pinellas County Matters

Coquina Key's low-lying, canal-front lots mean flood zone and elevation requirements come into play alongside the wind code, and a crew that pulls permits in St. Petersburg regularly knows what the local building department expects to see on a plan set before it ever reaches inspection. That familiarity saves real time on a build — fewer resubmittals, fewer surprise corrections mid-project. It also means we already know which frame and glass combinations hold up under Pinellas County's specific mix of hurricane-force wind, sustained UV, and salt air, instead of learning that on your house.

None of that replaces a straightforward, honest quote. If you're framing a new home, an addition, or a full rebuild on Coquina Key, we're glad to walk your plans, talk through the window package that fits your budget and your elevation, and give you a free, no-pressure estimate — no obligation, just a clear look at what the job actually needs.
