Product Overview - VLX 500 Sliding Window
The VLX 500 was engineered around a simple idea: a sliding window should disappear into the architecture, not compete with it. ViewLux achieved this with a 0.079-inch wall thickness that keeps the frame rigid without bulk, and a 1.97-inch profile width that maximizes glass area. The result is more daylight, cleaner views, and a contemporary look that pairs well with the flat roofs and stucco exteriors common throughout Doral.
This is an aluminum system, which matters in South Florida. Aluminum doesn’t warp in humidity, won’t rot like wood, and stands up to salt air if you live near the western edges of Doral closer to the Everglades. The thermal break construction separates interior and exterior frame surfaces, so you get that structural durability without the heat transfer that plagued older metal windows.
Operation is where the VLX 500 earns its reputation. The roller and track system is designed for minimal resistance, even on larger panels. You can open a 6-foot slider with one finger. That matters for daily use, and it matters for longevity. Less friction means less wear on hardware and seals over a 20-plus-year service life. Choose from 2-track or 3-track configurations depending on how many operable panels you need and the width of your rough opening.

AfterPerformance Features
Thermal Efficiency
The VLX 500 uses a polyamide thermal break that creates a thermal barrier between the aluminum exterior and interior frame surfaces. This is NFRC-rated construction, meaning the entire assembly, not just the glass, is tested for U-factor and Solar Heat Gain Coefficient. In Doral’s climate, that translates to less heat entering your home through the frame itself, which reduces the load on your AC and keeps interior temperatures more consistent room to room.
Acoustic Performance
Aluminum framing with proper thermal break construction, combined with dual-pane glass and quality perimeter seals, provides measurable sound attenuation. For homeowners near NW 36th Street, the Palmetto Expressway, or flight paths into Miami International, the VLX 500 with laminated glass can drop exterior noise significantly. We can discuss STC ratings during your estimate based on your specific glass package.
Airtightness & Weather Seal
Multiple compression seals at the meeting stile and frame joints stop air infiltration at every closure point. The VLX 500 is tested for air leakage under pressure, and the hardware is adjusted during installation to maintain consistent seal compression as the house settles. In Doral’s windy spring months, you’ll notice the difference in both comfort and dust accumulation.
Waterproofing
The sill profile includes a sloped drainage track and weep system that moves water to the exterior even during driving rain. During installation, we apply AAMA 812 low-expansion foam sealant at all perimeter joints, creating a continuous barrier between the window frame and the rough opening. This is where most water intrusion starts, and it’s where amateur installations fail.
Wind Resistance
The VLX 500 frame and glazing system is wind-load rated for South Florida requirements. The 0.079-inch wall thickness provides the structural backbone, and the laminated glass option adds impact resistance for debris protection. For Doral properties in higher exposure zones or those seeking HVHZ certification, we can engineer the installation to meet the specific pressures your building department requires.
Security & Hardware
Multi-point locking engages at the sill and header simultaneously, not just at the handle. The aluminum construction resists forced entry better than vinyl alternatives, and tempered or laminated glass options add another layer of protection. Hardware finishes are matched to your frame color for a clean, intentional look.
Color & Glass Options

Six finishes let the VLX 500 adapt to Doral’s architectural variety. Premium Black and Anodized Silver suit the minimalist modern homes going up near Downtown Doral and CityPlace. Pure White blends with traditional Mediterranean and barrel-tile roofs you’ll find in older Doral neighborhoods. Bronze and Champagne warm up stucco exteriors without the maintenance of actual wood. Teak Wood gives you the grain aesthetic for tropical or transitional designs, but in aluminum that won’t swell or require refinishing.
Glass selection should match how you use the room. Clear glass maximizes visible light and views. Frosted works for bathrooms and privacy walls facing neighbors. Low-E coating is the standard choice for east and west exposures in Doral, reflecting infrared heat while letting light through. Tempered is required by code for large panels and areas near doors or wet spaces. Laminated adds the impact resistance and sound control mentioned above, and the interlayer holds glass in place if broken.
Screen choice is functional preference. The Retractable Screen stores out of sight when not needed, preserving your view. The Sliding Screen is the traditional paired panel that moves with the operable sash. In Doral, where insects are a year-round reality, either option beats leaving the window open unscreened.
Installation by Sightline Windows & Doors Doral in Doral
We install the VLX 500 according to AAMA 2400 and 2410 standards, which specify how aluminum windows interface with the wall system, drainage plane, and interior finish. This isn’t optional paperwork. It’s the installation protocol that ViewLux requires for warranty validation, and it’s what separates a window that performs for decades from one that leaks in year three.
Our process starts with a pre-install inspection of your rough opening. We check for square, level, and plumb. In Doral, we often find that block construction or wood framing has settled slightly, especially in homes built during the 1990s and 2000s growth periods. We shim and correct before the frame goes in, because a twisted opening will stress the sash and hardware for the life of the window.
The frame is set, leveled, and anchored. Then we apply AAMA 812 low-expansion foam sealant at all perimeter joints. This creates an airtight, waterproof bond between the aluminum frame and the surrounding structure without distorting the frame, which can happen with standard expanding foam. We flash the head and integrate with your existing or new weather-resistive barrier.
After installation, we operate every sash, check all locks, and run a water test on the sill. We clean the glass and tracks before we leave. The final step is documenting the installation for your ViewLux warranty registration, which we handle.
Improper installation voids the manufacturer warranty. We’ve been called to fix too many Doral jobs where a handyman or unlicensed installer skipped the foam seal, didn’t flash the head, or forced a frame into an out-of-square opening. The window looked fine on day one. Two rainy seasons later, the homeowner had interior drywall damage and no warranty coverage. Professional installation isn’t an upsell. It’s the condition of the warranty.
Doral’s hot, humid climate and occasional tropical storm exposure make proper installation especially critical. Our crews work here exclusively. We know the local building department’s inspection triggers, the wind-borne debris zones, and the specific challenges of Doral’s soil conditions and settlement patterns.
Frequently Asked Questions - VLX 500 Sliding Window

What is the lead time for the VLX 500 Sliding Window?
Lead time typically runs 4 to 6 weeks from signed approval to delivery, depending on your finish and glass selection. Custom sizes and specialty finishes like Teak Wood may extend this slightly. We keep standard colors moving through production to minimize wait times for Doral projects. Call (786) 460-1563 to check current availability for your configuration.
Does the VLX 500 qualify for energy tax credits?
The VLX 500 with Low-E glass and NFRC-rated thermal break construction may qualify for federal energy efficiency tax credits depending on the tax year and your total installation cost. We provide all NFRC performance documentation at the time of purchase so you or your accountant can verify eligibility. Tax law changes, so we don’t promise specific credit amounts. Call (786) 460-1563 and we’ll share the current performance ratings for your planned configuration.
What warranty comes with the VLX 500 Sliding Window?
ViewLux provides a limited lifetime warranty on the aluminum frame and hardware, with glass coverage for seal failure and stress cracking under normal use. The warranty is transferable once if you sell your home. Coverage requires installation by an authorized partner like Sightline Windows & Doors Doral, using AAMA-compliant methods. DIY or non-authorized installation voids protection. We’ll register your warranty and provide documentation before we leave the job site.
Can I customize the size of the VLX 500?
Yes, the VLX 500 is available in custom dimensions to fit your existing rough openings or new construction plans. We measure on-site to 1/8-inch precision and factory-order each unit. Custom sizing does not affect the warranty or performance ratings. Very large openings may require structural reinforcement or divided-lite configurations, which we’ll discuss during your free estimate. Call (786) 460-1563 to schedule measuring.
How do I maintain aluminum frames in Doral’s climate?
Rinse the exterior frames with fresh water every 3 to 4 months to remove salt and dust buildup, especially if you live west of the Turnpike where Everglades breezes carry minerals. Lubricate the track and rollers annually with a silicone-based product, not oil. Clean glass with standard non-abrasive cleaner. The powder coat finish is baked on and won’t require repainting. Avoid pressure-washing directly into weep holes, as this can force water into the drainage system backward.
