Fixed and Picture Impact Windows: Maximum Glass, Minimum Hardware

A fixed impact window has no operator, no track, no lock, and no seal that can wear out. It is the highest performing and lowest maintenance unit in any impact product line, and it is routinely under-specified. The same principle plays out differently depending on where in South Florida a home sits, from Boynton Beach’s exposure category down to which product approval a permit reviewer expects to see.

Why fixed units test highest

Every operable window is a compromise between performance and function. A sash that moves needs clearance, and clearance is where air and water get in. A fixed lite is glazed directly into the frame with no moving joint at all.

The result is that fixed units typically carry the highest design pressure ratings and the lowest air infiltration numbers in a given product family.

Cost per square foot

Fixed units also cost less per square foot than any operable configuration, because there is no hardware, no screen, and no operator to buy.

On a large water-facing elevation, specifying fixed glass where ventilation is not needed frees budget to upgrade the units that do need to open.

Homeowners comparing configurations can review the full range of fixed and picture impact windows before specifying.

Designing the ventilation plan around them

• Fixed center picture unit flanked by operable casements
• Fixed lower lite with an awning transom above
• Full height fixed glass with ventilation handled by an adjacent slider
• Mulled assemblies where fixed and operable share a single frame

The ventilation math

Florida requires natural ventilation or mechanical ventilation for habitable rooms, and sleeping rooms require egress. A wall of fixed glass has to be balanced by operable openings elsewhere in the room.

This is a permit question, not a preference question. It gets resolved at the design stage rather than at inspection.

Fixed glass on Boynton’s 1970s and 1980s retrofit stock

A large share of Boynton Beach’s housing dates to the 1970s through 1990s, a period when large single-pane fixed windows were common on great room and Florida room elevations facing the backyard. These openings are frequently oversized relative to what a stock fixed impact unit’s approval chart covers, which is where a mulled assembly, rather than a single oversized lite, keeps the retrofit inside a valid approval.

Because this era of construction sits before modern anchoring standards, the substrate around these openings often needs evaluation once the original frame comes out, similar to what turns up in comparable vintage homes throughout Palm Beach County.

Balancing fixed glass against egress near the Loxahatchee refuge side of town

Homes on the western side of Boynton Beach, closer to the Arthur R. Marshall Loxahatchee National Wildlife Refuge, tend to sit on larger lots with more expansive rear glass facing the preserve view. That view-driven design pushes toward more fixed glass area, which has to be balanced against the egress requirement in any adjacent sleeping room.

Working the egress calculation before finalizing the glazing plan, rather than after the order is placed, avoids a permit rejection on an otherwise straightforward preserve-view retrofit.

Where this shows up across our service area

Boynton Beach sits between Delray Beach to the south and the Lantana and Lake Worth area to the north, with the Arthur R. Marshall Loxahatchee National Wildlife Refuge marking the western edge of the developed city and the Green Cay Nature Center and Wetlands offering a closer inland green space. Oceanfront Park and the Boynton Inlet mark the coastal side, where marinas and waterfront dining sit just off the Intracoastal. A large share of the city’s housing dates to the 1970s through 1990s, putting much of it squarely in the retrofit window rather than the new-construction window.

Federal Highway and I-95 both run through Boynton Beach on a north-south axis, connecting its coastal neighborhoods to the newer development further west near the Turnpike. As in the rest of Palm Beach County, every opening here sits in the Wind-Borne Debris Region rather than the High-Velocity Hurricane Zone, which changes which product approval documentation actually applies at permitting.

For this specific project type in Boynton Beach, that means the geo-entity detail above is not background context, it is the difference between a specification that clears permitting on the first submission and one that gets kicked back for an approval mismatch.

The regulatory layer: HVHZ versus the Wind-Borne Debris Region

Palm Beach County sits in Florida’s Wind-Borne Debris Region rather than the High-Velocity Hurricane Zone, which is limited by code to Miami-Dade and Broward counties. That distinction matters at permitting: openings here are approved under a statewide Florida Product Approval number rather than a Miami-Dade Notice of Acceptance, tested to large missile impact and cyclic pressure standards under ASTM E1996 and E1886 rather than the Miami-Dade TAS protocol. The practical performance target is similar, and in practice many manufacturers carry both approvals on the same product line, but a permit reviewer checking documentation is looking for the Florida Product Approval number, not an NOA.

For fixed impact window florida specifically, that means the paperwork a Boynton Beach permit reviewer expects to see on a fixed impact window florida submission is a Florida Product Approval number matched to the exact configuration installed, not a generic manufacturer brochure or a product approval for a different size or panel count.

Who we install

As authorized dealers, our installs draw from CGI, PGT, ES Windows, Eco Windows, WinDoor, Tecnoglass, PlastPro, and Therma Tru, each carrying its own line of Florida Product Approvals and, where applicable, Miami-Dade Notices of Acceptance across different design pressure ranges and price points. Product selection is matched to the exposure category and approval requirement of the specific address, not sold off a single default line.

Each of those manufacturers maintains its own catalog of Florida Product Approvals and, where applicable, Miami-Dade or Broward Notices of Acceptance, organized by product series, frame material, and glazing configuration. Verifying the specific approval number against the manufacturer’s published database, rather than accepting a verbal assurance that a product is rated, is a five-minute step available to any homeowner before a contract is signed, and it is the single most reliable way to confirm that what is quoted for fixed impact window florida is actually what a permit reviewer will approve.

What to verify before signing a contract for fixed impact window florida

Every quote for fixed impact window florida should answer the same short list of questions before a deposit changes hands. What is the exact product line and model number, and does the written proposal name that model rather than a generic description like impact windows or hurricane doors. What is the design pressure rating for the specific opening sizes on this house, not a single number applied to the whole project. Which product approval covers that configuration, a Florida Product Approval number for Palm Beach County work or a Miami-Dade or Broward Notice of Acceptance for Broward County work, and is that number current.

Beyond the product itself, the contract should specify who pulls the permit, what the installation warranty covers separately from the manufacturer’s glass and hardware warranty, and whether stucco or drywall repair around the opening is included or billed separately. A proposal silent on any of these points is a proposal likely to generate a change order once work starts, and asking the questions before signing costs nothing.

Why South Florida homeowners choose STS for fixed impact window florida

STS Impact Windows & Doors was built around a specific combination: military discipline from a veteran founder and two and a half decades of hands-on South Florida construction experience from a general contracting partner. That combination shows up in the details competitors often skip, an industry-leading 3-year installation warranty that sits on top of the manufacturer’s product warranty, a 100 percent satisfaction guarantee, and after-installation repairs included rather than billed as a separate service call.

The company holds authorized dealer status across eight major manufacturers, which means product recommendations are not limited to whichever single brand a crew happens to install. Every project runs through the same four core values regardless of size: transparency in what the homeowner is told at every stage, excellence in material selection, efficiency in scheduling, and timeliness in completion, values that matter as much on a single-window repair as on a whole home retrofit.

That structure also shows up in what the company does not do. There is no upsell to a different product line mid-project once a deposit is collected, no subcontracted labor brought in without the homeowner’s knowledge, and no installation scheduled without the permit already filed. For a South Florida homeowner comparing quotes, that consistency is frequently the difference between a project that finishes on the quoted timeline and one that does not.

Common mistakes homeowners make with fixed impact window florida

The most frequent and most expensive mistake is comparing two quotes on price alone when the underlying design pressure ratings are not actually the same. A lower bid on a lower-rated product is not a discount, it is a different, less protective purchase, and it often fails inspection outright in a county with strict wind-borne debris provisions.

The second most common mistake is protecting the windows while deferring the doors or the garage, then discovering the insurance wind mitigation credit does not apply to a partially protected home. The third is skipping the HOA or historic review step where one applies, which can mean removing and reordering correctly installed, correctly rated product simply because the frame color or grid pattern was never submitted for approval.

A fourth, quieter mistake shows up months after installation rather than at signing: treating the product as maintenance-free because it is impact rated. Weep holes still need clearing, hardware still needs periodic lubrication, and gaskets still age, particularly in the coastal stretches of the service area. None of that voids the rating, but neglecting it shortens the years before the first service call is needed.

Timeline: fitting fixed impact window florida into a hurricane season deadline

Hurricane season in Florida begins June 1st, and impact product for fixed impact window florida is fabricated to order rather than pulled off a shelf, which makes lead time, not installation time, the constraint homeowners underestimate most. A realistic sequence starts with a measure and specification visit, moves through HOA or historic review where one applies, then into fabrication, which is typically the single longest phase of the project, before permitting and a two to five day installation window for most single-family scopes.

Homeowners who begin that sequence in late spring, once the prior year’s season has closed and before demand compresses lead times heading into summer, are the ones who reliably finish before the next season opens. Starting the conversation in August, once a storm is already being named, means competing for fabrication slots against every other homeowner in South Florida making the same call at the same time.
