VLX 80 Casement Window

VLX 80 Casement Window in Port St. Lucie, FL | TruePane Windows & Doors

The VLX 80 Casement Window is a side-hinged aluminum window built for homeowners in Port St. Lucie who want wide-open ventilation without bulky frames eating into the view. Manufactured by ViewLux and installed by TruePane Windows & Doors as an authorized partner, this window pairs a 1.97-inch profile with glass that stretches nearly edge to edge. It’s a popular choice for lakefront homes along the St. Lucie River, newer builds in Tradition, and mid-century ranches across eastern St. Lucie County.

Product Overview - VLX 80 Casement Window

The VLX 80 is built around a simple idea: the frame should disappear. At just 1.97 inches wide on the visible face, the profile is one of the slimmest aluminum casement designs ViewLux produces. When closed, the sash sits nearly flush with the fixed frame, which reads clean and architectural from both inside and out. When open, the entire sash cranks outward on side hinges, catching coastal breezes from the Atlantic and channeling them through the house. That’s real ventilation, not the partial airflow you get from a sliding or double-hung window.

Aluminum was chosen here for good reason. It doesn’t warp in the humidity that defines a Port St. Lucie summer, and it won’t rot or swell the way wood frames eventually do in salt-adjacent air. The wall thickness measures 0.079 inches, which gives the extrusion enough rigidity to hold large glass panels without bowing. That stiffness matters when a late-afternoon thunderstorm pushes wind against a wide casement sash.

Architecturally, the VLX 80 fits modern and contemporary homes especially well. We’ve installed them in concrete-block ranch renovations off Prima Vista Boulevard, new construction in St. Lucie West, and elevated coastal builds near the North Fork of the St. Lucie River. The narrow frame complements clean stucco lines and flat roofs. For traditional Florida homes, the champagne and teak wood finishes soften the modern profile enough to blend with existing trim. The casement mechanism itself gives you a full clear opening, which also makes it a smart choice wherever egress matters, like a bedroom or home office.

Technical Specifications

Here’s how the VLX 80 Casement Window is configured, in plain terms:

• Frame material: Extruded aluminum with a 0.079-inch wall thickness for structural rigidity.
• Visible frame width: 1.97 inches, ultra-narrow for maximum glass area.
• Operation: Side-hinged casement with crank-out operation, full clear opening when open.
• Glass package options: Clear, frosted (privacy), Low-E (solar control), tempered (safety glazing), and laminated (impact-rated).
• Finish options: Premium Black, Pure White, Anodized Silver, Bronze, Champagne, and Teak Wood.
• Screen options: Fixed screen or retractable screen, depending on ventilation preference.
• Sill options: Standard sill or low-profile sill for minimal step-over height at the opening.
• Energy standard: Thermal break technology, NFRC-rated for energy performance.
• Installation standard: AAMA 2400/2410 compliant installation with AAMA 812 low-expansion foam on all perimeter joints.
• Ratings: Airtightness, waterproofing, mist prevention, and sound control performance built into the system’s design.

Performance Features

Thermal Efficiency
The VLX 80 uses a thermal break built into the aluminum frame. That barrier interrupts the metal-to-metal conduction path that would otherwise transfer outdoor heat through the frame. In Port St. Lucie, where air conditioning runs ten months a year, an NFRC-rated thermal break cuts the load on your HVAC and keeps the interior frame surface from sweating during humid stretches.

Acoustic Performance
Aluminum casement windows close tight against a compression seal on all four sides. That continuous seal, combined with the frame design’s sound control rating, reduces road noise from US-1, Turnpike traffic, and neighborhood activity. If you live near a canal where boat traffic runs on weekends, the VLX 80 with laminated glass makes a measurable difference in how quiet the room feels.

Airtightness & Weather Seal
Casement hardware pulls the sash firmly into the weatherstripping as you crank it closed. Unlike sliding windows that rely on brush seals, a casement compresses its gasket, creating a true airtight seal. For Port St. Lucie homes, that means less humid outdoor air leaking in around the sash, which directly affects indoor comfort and the electric bill.

Waterproofing
The VLX 80’s drainage design channels water away from the interior without relying on silicone to do the job. Weep paths at the sill let rainwater drain outward, and the compressed perimeter seal keeps driven rain out of the frame channel. Proper installation per AAMA 2400/2410 ensures the drainage path stays open and functional for the life of the window.

Wind Resistance
A casement window braces closed against wind, the way a door held shut by a deadbolt outperforms a door held by a latch. The multi-point locking hardware on the VLX 80 ties the sash into the frame at several points, and the 0.079-inch wall thickness gives the extrusion the stiffness to carry wind-load ratings appropriate for coastal Florida. Impact-rated laminated glass is available for homes that need storm protection without shutters.

Security & Hardware
The crank mechanism on the VLX 80 works on a multi-point closure system, not a single latch. Once cranked shut, the sash locks into the frame at multiple points along its height. The hardware is concealed within the profile, keeping the narrow sightlines clean, and the locking points make the window far more resistant to forced entry than a typical sliding window.

Color & Glass Options

The VLX 80 is available in six finishes, and the right choice depends on the look of your Port St. Lucie home. Premium Black is the standout choice for modern and contemporary builds, giving the window an architectural presence against white stucco. Pure White disappears into traditional trim and suits most Florida ranch homes. Anodized Silver reads technical and clean, popular in coastal modern designs. Bronze bridges the gap, adding warmth without going dark and pairs well with terracotta roof tones. Champagne is softer than silver and suits homes with warm beige or cream exteriors. Teak Wood gives the aluminum frame a warm, wood-look finish without the maintenance of real wood, ideal for homes where the interior design leans traditional.

Glass selection depends on what each room needs. Clear glass gives an unobstructed view. Frosted glass provides privacy for bathrooms or rooms facing a neighbor. Low-E glass is the practical standard for east and west exposures in Florida, reflecting solar heat while keeping the view. Tempered glass meets safety glazing codes for large sashes and doors. Laminated glass, including impact-rated options, provides storm protection and added sound reduction. We help Port St. Lucie homeowners match glass per opening based on exposure, code, and budget.

Installation by TruePane Windows & Doors in Port St. Lucie

Installing a precision aluminum casement window incorrectly will ruin a great product. A window installed out of square will bind the crank mechanism. A perimeter sealed with the wrong material will leak within a year. And any installation that doesn’t follow the manufacturer’s written instructions voids the ViewLux warranty. That’s the practical case for using TruePane Windows & Doors in Port St. Lucie.

We start with a pre-install inspection of the rough opening. We check for rot, termite damage, and dimensional issues in the existing frame before removing anything. If we find a problem behind an old window in an older Port St. Lucie neighborhood, we address it before setting the new unit, so you’re not paying for a window that fails in three years.

When we set the VLX 80, the sash is shimmed and adjusted until the frame is perfectly level, plumb, and square, then the operating sash is tuned so the crank moves smoothly without resistance. The perimeter is sealed with AAMA 812 low-expansion foam per AAMA 2400/2410 installation standards. That foam fills the gap between the window frame and the rough opening, and because it’s low-expansion, it won’t bow the frame out of square as it cures. Every install ends with a hose test on the exterior and a final wipe-down of the frames and glass.

For Port St. Lucie specifically, our installation approach accounts for concrete-block construction common in homes from the 1970s onward, hurricane-season wind-driven rain from the southeast, and code requirements tied to our location in a high-velocity hurricane zone. We don’t ship in a template from another market. We install these windows the way a local company that will still be here in twenty years should.
