We’re the Impact Windows & Doors team at Sightline, and our crews serve Lantana from our South Florida coordination office - close enough that we know the difference between a home off Hypoluxo Road and one near the Ocean Avenue corridor, and what that means for your opening specs.

Why Salt Air Near the Intracoastal Dictates Your Materials
Every home in Lantana sits within a few blocks of salt water. The town’s roughly two-square-mile footprint straddles the Intracoastal Waterway, which means the entire housing stock breathes salt-laden air year-round. This isn’t a waterfront-fringe problem like you’d find in parts of Boynton Beach. It’s the baseline condition.
We’ve pulled original jalousie frames from 1960s CBS stucco homes off Hypoluxo Road and found the aluminum sash corroded into the block itself. The crew saw-cut the masonry openings, rebuilt the jambs, and set new PGT impact-rated units with stainless hardware and a large-missile-rated laminated glass interlayer. The homeowner got a wind mitigation report showing all openings now meet HVHZ-level criteria. That job wasn’t an outlier. In Lantana, it’s the standard.
Here’s what this means for your budget. The cheap inland spec - standard aluminum frames, zinc-plated fasteners, basic vinyl seals - fails faster here than it would twenty miles west. Salt accelerates seal degradation, hardware corrosion, and IGU fogging. We specify marine-grade finishes, stainless or hot-dip galvanized fasteners, and sealed joints rated for coastal exposure. The upfront cost gap between coastal-spec and inland-spec hardware runs roughly 15-25% per opening. The replacement cost if you go cheap? Full removal and reinstall within eight to twelve years, plus whatever water intrusion damage the failed seals caused in the meantime.

Hurricane Impact Windows
Lantana sits in Palm Beach County’s High Velocity Hurricane Zone, which makes Florida Product Approval a code requirement for any permitted replacement - not an upgrade. We specify large-missile-rated laminated interlayers from PGT, CGI, or CWS, depending on your opening size and exposure. Every unit we install meets or exceeds the HVHZ criteria the county inspector will check.
Impact-Resistant Windows
Impact resistance isn’t only about the glass. In Lantana’s salt environment, the frame material, fastener specification, and seal chemistry matter as much as the laminated pane. We stock marine-grade hardware and specify finishes that survive within a mile of the Intracoastal. The wrong frame here corrodes before the glass ever sees a named storm.
Single Hung Impact Windows
The fixed upper sash and operable lower sash of a single hung unit suit Lantana’s smaller original openings, many of which were sized for jalousie units in the 1960s and 1970s. We measure the existing masonry opening, account for any block cutting required, and specify the unit that fits without compressing the frame into a corroded rough opening.
Double Hung Impact Windows
Both sashes operable, better ventilation control, and easier cleaning from inside - useful in Lantana’s year-round humidity where exterior maintenance accelerates wear. We install double hung units from ES Windows and ECO Window Systems with tilt-in sashes and coastal-grade balances that resist salt corrosion.
Horizontal Roller & Sliding Impact Windows
Common for patios and wide openings facing the Intracoastal. The roller hardware takes the load, and cheap rollers seize in salt air. We specify stainless or polymer-impregnated track systems with sealed bearings, rated for coastal cycling.
Wind Mitigation & HVHZ Code Compliance
Every permitted impact window installation in Lantana requires HVHZ compliance documentation. We provide the wind mitigation report your insurer needs, showing opening protection that satisfies the 160+ mph design standard. This isn’t paperwork we add on. It’s part of the scope, included in the written price.

Trusted Brands We Service in Lantana
We draw from eight manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - and we specify by what your opening requires, not by what sits in a warehouse. For Lantana’s salt-air conditions, we frequently reach for CWS and ES Windows frames with marine-grade anodizing, or ECO Window Systems vinyl formulations rated for coastal UV and salt exposure. Mr-Glass laminated interlayers show up in our large-missile specifications where the exposure is direct. We don’t stock “local parts” because every job starts with a measured survey; we order to the spec, and the turnaround matches our South Florida supply chain.
Common Impact Windows & Doors Problems We See in Lantana Homes
- Original jalousie frames corroded into CBS masonry. The aluminum sash in 1950s-1970s Lantana homes often bonds to the block through decades of salt intrusion. Removal requires saw-cutting, not prying. Full-frame replacement is the norm here, not insert retrofit.
- IGU fogging from failed seals in salt-laden humidity. Cheap vinyl seals degrade faster within a mile of the Intracoastal. We specify seal systems rated for coastal cycling and back them with the manufacturer’s coastal warranty.
- Hardware corrosion on zinc-plated fasteners. Standard fasteners rust through in four to six years here. We use stainless or hot-dip galvanized hardware, period. No exceptions for Lantana jobs.
- Non-compliant jalousie units blocking permit approval. When Lantana homeowners sell or renovate, the original louvered glass windows fail inspection. We replace with code-compliant impact units and provide the documentation for closing or permitting.

FAQs - Impact Windows & Doors in Lantana
Yes. Palm Beach County requires Florida Product Approval for all impact-rated window and door installations in its jurisdiction, and Lantana’s 160+ mph design wind-speed zone places it in the High Velocity Hurricane Zone. Every unit we install carries the NOA or FL Product Approval number your permit application and inspector will require. Call (561) 354-3861 and we’ll show you the documentation before you commit.
The aluminum frames in Lantana’s 1960s CBS homes are often corroded into the original masonry, so removal requires saw-cutting the block and rebuilding the jambs. An insert retrofit - sliding a new unit into the existing frame - isn’t possible when the frame is mechanically bonded to the block. The labor and materials for full-frame replacement, plus the masonry repair, add $180-$340 per opening over a clean insert job. We flag this in your measured survey so the written quote includes it upfront.
They will, though the salt-air climate affects how you measure the savings. Impact windows with low-SHGC coatings reduce solar heat gain, which is the largest cooling load in South Florida. The tighter seal of a new frame also cuts the humidity infiltration that makes air conditioners work harder. In Lantana’s year-round humidity, the comfort gain often matters as much as the kilowatt-hour reduction. We specify U-factor and SHGC values on every quote so you can compare performance, not just price.
Stainless steel or hot-dip galvanized fasteners, marine-grade anodized aluminum frames, and coastal-rated vinyl formulations with UV stabilizers. Zinc-plated hardware shows rust in four to six years here. We specify the coastal grade on every Lantana job, and we document the hardware type in your photo record. If a competitor’s quote doesn’t name the fastener spec, ask why.
Florida statute requires insurers to offer discounts for wind mitigation improvements that reduce windstorm losses, and impact-rated windows with HVHZ documentation qualify. The exact discount depends on your carrier and the overall wind mitigation score. We provide the uniform mitigation verification form and the product approval documentation your agent needs. Call (561) 354-3861 and we’ll walk you through what to submit.
