Product Overview - VLX 500 Sliding Window
ViewLux designed the VLX 500 around a simple idea: a sliding window should disappear into the architecture, not compete with it. The result is an aluminum frame system with a remarkably slim profile that maximizes glass area while maintaining the structural integrity South Florida building codes demand.
The 0.079″ wall thickness gives the extrusion real substance. You feel it when you grip the frame. The 1.97″ profile width keeps sightlines narrow, so your view of Three Lakes’ palms, pines, and water features stays uninterrupted. Operation is genuinely smooth. The roller and track engineering eliminates the grittiness and sticking that cheaper systems develop after a few humid summers.
We install the VLX 500 in two configurations. The 2-track setup suits most standard replacement scenarios, one fixed panel and one operable. The 3-track option adds a middle panel that slides either direction, giving you more ventilation flexibility for great rooms, covered lanais, and master bedrooms where cross-breezes matter. Both versions use the same hardware and sealing systems, so performance stays consistent regardless of layout.
Aluminum was the right material choice for this region. It won’t swell, warp, or rot in Three Lakes’ subtropical humidity. The thermal break technology addresses the conductivity issue that plagued older aluminum windows, so you get the durability without the energy penalty.

AfterPerformance Features
Thermal Efficiency
The thermal break separates interior and exterior aluminum surfaces, cutting conductive heat transfer significantly. NFRC-rated performance means the numbers are verified by independent testing, not marketing claims. In Three Lakes, where summer cooling loads run high for eight months of the year, this translates to real utility savings and more consistent indoor temperatures near west-facing glass.
Acoustic Performance
Laminated glass options add mass and damping that single-pane systems cannot match. The same interlayer that holds the glass together on impact also disrupts sound waves. For homes near US-27 traffic or areas with frequent afternoon thunderstorms rolling across the lake, the acoustic benefit is noticeable. We specify laminated glass for master suites and home offices where quiet matters.
Airtightness & Weather Seal
Multiple compression seals and engineered interlocks close tightly when the sash meets the frame. The AAMA 812 low-expansion foam sealant we apply at all perimeter joints fills irregularities in the rough opening that caulk alone cannot address. This matters in Three Lakes during pollen season and when Saharan dust events push fine particulates through every gap.
Waterproofing
Sloped sills, internal drainage channels, and pressure-equalized design manage water that reaches the frame. The system is tested to AAMA standards for water penetration resistance. In a region where afternoon convection storms dump inches in minutes, this engineered drainage path protects your walls and finishes from the damage that improper flashing invites.
Wind Resistance
The 0.079″ wall thickness and reinforced corners handle the wind loads that Florida building codes anticipate. With laminated impact glass, the VLX 500 meets the requirements for High Velocity Hurricane Zones. We’ve installed these in Three Lakes homes where the open lake exposure creates sustained pressure that lighter systems simply cannot tolerate.
Security & Hardware
Multi-point locking engages at several locations along the sash, not just one catch. The hardware is corrosion-resistant, tested for coastal and humid environments. For ground-floor installations and rear-facing windows in Three Lakes, we recommend the laminated glass option for its forced-entry resistance as well as its storm protection.
Color & Glass Options

Six finishes give the VLX 500 flexibility across architectural styles common in Three Lakes. Premium Black and Anodized Silver suit the contemporary homes going up near newer lakefront developments, clean lines that complement flat roofs and minimal trim. Pure White remains the standard for traditional Florida ranch and Mediterranean-influenced exteriors, bright and reflective under intense sun. Bronze and Champagne offer middle-ground warmth that blends with terra cotta roofs and natural stone without the stark contrast of black. Teak Wood finish carries the warmth of natural grain into the aluminum frame itself, popular for homes with exposed wood ceilings and covered porches where interior and exterior materials converse.
Glass selection should match how you live in each room. Clear glass maximizes visible light transmission for north-facing spaces and views you want unobstructed. Frosted provides privacy for bathrooms and side yards without sacrificing daylight. Low-E coating reflects infrared heat while passing visible light, the standard specification for west and south exposures in Three Lakes where solar gain drives cooling costs. Tempered glass meets safety code for operable panels and areas near doors. Laminated glass delivers impact resistance, sound control, and UV filtration in one package, our recommendation for most Three Lakes installations given the combined threat of storms and sun.
Screen choice affects daily use. Retractable screens store out of sight when windows are closed, preserving the clean view that drew you to the slim profile. Sliding screens stay in the track, always ready, with simpler mechanics and lower cost.
Installation by Sightline Windows & Doors Three Lakes in Three Lakes
Window performance lives or dies at installation. A premium product installed poorly performs worse than a mid-grade unit set right. At Sightline Windows & Doors Three Lakes, we treat the installation as engineering, not carpentry.
Every project starts with a pre-install inspection. We measure each opening individually, check for square, and identify structural issues that could affect drainage or operation. Three Lakes homes span decades of construction, and rough openings from the 1970s rarely match modern tolerances. We note settling, water damage, and framing irregularities before the first unit arrives.
Setting the frame demands precision. Level, plumb, and square are not suggestions. They are requirements for proper sash operation, seal compression, and drainage function. We shim and anchor to maintain these tolerances across the full perimeter, then verify with digital levels before proceeding.
Perimeter sealing follows AAMA 812, low-expansion foam sealant applied to all joints between frame and rough opening. This creates a continuous air and water barrier that flexible caulk alone cannot achieve. The foam expands to fill gaps, then cures to a resilient seal that moves with the structure through seasonal temperature swings. In Three Lakes, where daily temperature swings of twenty degrees stress building materials year-round, this flexibility prevents the cracks that admit water and air.
We install to AAMA 2400/2410 standards, the recognized benchmark for fenestration installation. This compliance matters for warranty protection. ViewLux, like most manufacturers, voids coverage if installation deviates from specified methods. Our authorized partner status requires this adherence, and our documentation protects your investment.
Final water testing confirms every seal and drainage path before we leave. We clean the site completely, remove old materials, and walk you through operation and maintenance. In Three Lakes, we also verify that installations meet any applicable wind-borne debris or impact requirements for your specific zoning.
Improper installation voids manufacturer warranty. We’ve been called to fix other contractors’ work where frames were out of square, drainage holes were blocked, or foam was skipped entirely. The homeowner paid twice. We prevent that outcome by doing it correctly the first time.
Frequently Asked Questions - VLX 500 Sliding Window

Lead time typically runs 4 to 6 weeks from signed approval to delivery, depending on finish and glass selection. Custom sizes and Teak Wood finish occasionally extend toward the longer end. We order as soon as you approve your written quote, and we coordinate delivery to minimize your wait. Call (786) 808-5792 to check current availability and reserve your production slot.
The Low-E glass configuration with NFRC-rated thermal break performance may qualify for federal energy efficiency credits depending on current IRS guidance and your total installation cost. We provide all NFRC labels and product certification documentation needed for your tax preparer. Tax law changes, so we do not guarantee eligibility, but we ensure you have the paperwork to claim any available benefit. Call (786) 808-5792 and we’ll discuss which glass package optimizes both performance and potential credits.
ViewLux provides a limited lifetime warranty on the frame and sash, with 20-year coverage on the insulated glass unit and 10 years on hardware, subject to proper installation by an authorized partner. Our Sightline Windows & Doors Three Lakes installation carries a 5-year workmanship warranty covering seal integrity, operation, and installation-related issues. Warranty claims require documentation of authorized installation, which is why working with a ViewLux partner matters. Call (786) 808-5792 for complete warranty terms.
Yes, the VLX 500 is available in custom dimensions to fit existing openings or new construction plans. We measure on-site to verify rough opening dimensions, then factory-order units sized to your specific requirements. Custom sizing does not affect the warranty or performance ratings when installed to AAMA standards. Call (786) 808-5792 to schedule your free measurement.
Rinse frames quarterly with fresh water to remove salt and pollen accumulation, especially if you’re near the lake or any brackish water. Wash annually with mild soap and a soft brush, then rinse thoroughly. Lubricate the track and rollers yearly with a silicone-based product, never petroleum grease which attracts grit. Inspect weep holes seasonally to ensure drainage paths stay clear. The powder coat finish resists fading and chalking, but avoiding abrasive cleaners preserves its appearance for decades. Call (786) 808-5792 if you notice operation changes or seal concerns between maintenance intervals.
