Product Overview - VLX 500 Sliding Window
The VLX 500 is the window you spec when you want the opening itself to disappear. The frame measures just under two inches wide, which leaves more glass and less metal in the opening. That slim profile reads as modern and architectural, but we’ve installed this series in enough Los Angeles neighborhoods to know it works equally well in a mid-century ranch in Sherman Oaks, a stucco Spanish in Westchester, or a contemporary box in Silver Lake.
What sets this window apart is the engineering underneath the minimal frame. The wall thickness is 0.079 inches, which is a serious amount of aluminum for a residential window. That heavier extrusion resists racking and bending during transport and installation, and it keeps the frame stable over decades of thermal expansion and contraction. Los Angeles sees daily temperature swings of 30-plus degrees in the valleys, and thinner extrusions can work loose over time. The VLX 500 is built to hold its shape.
The glide mechanism is where the product earns its name. Buyers who have lived with vinyl sliders that stick and chatter are consistently surprised by how smoothly a well-built aluminum system moves. It’s a combination of machined rollers, precise track alignment, and the rigidity of the frame. The VLX 500 is available in 2-track and 3-track configurations, so you can run two or three operable panels depending on the width of the opening.
Westlight Windows & Doors has installed this series in single-family homes, condos, and light commercial storefronts throughout Los Angeles. We recommend it most often for wide openings where the window is a focal point rather than a background element: a wall of glass facing the backyard, a dining room opening onto a canyon view, a living room wall in a hillside home. If you’re replacing old aluminum sliders from the 1970s or 80s, this window is a direct upgrade in every measurable way.
Technical Specifications
Here are the specs that matter for the VLX 500. These are the numbers we walk through with every Los Angeles client during a site visit.
| Specification | Detail |
|---|---|
| Frame wall thickness | 0.079 inches |
| Profile width | 1.97 inches |
| Track configurations | 2-track, 3-track |
| Glass options | Clear, Frosted, Low-E, Tempered, Laminated |
| Finish options | Premium Black, Pure White, Anodized Silver, Bronze, Champagne, Teak Wood |
| Screen options | Retractable screen, Sliding screen |
| Performance compliance | AAMA 2400/2410 installation standard; AAMA 812 perimeter sealant |
| Energy rating | NFRC-rated with thermal break technology |
| Wind load | Rated for local Los Angeles climate requirements |
The 3-track configuration is particularly useful in Los Angeles because it allows a wider opening with more ventilation area without increasing the frame depth. We’ll talk through which glass and finish combination fits your specific elevation and exposure when we do the on-site measurement.
Performance Features
Thermal Efficiency
Thermal break technology. The VLX 500 uses a thermal break within the aluminum frame, which separates the interior and exterior metal surfaces and reduces heat transfer through the extrusion. Aluminum conducts heat extremely well, which is why older LA aluminum windows turned into radiators by 3 pm. The thermal break plus NFRC-rated glazing packages cut that heat bridge dramatically and bring the window into compliance with California Title 24 energy codes.
Acoustic Performance
Sound control for urban Los Angeles. If your home sits near the 405, the 101, or a busy surface street like Wilshire or Sunset, acoustic performance isn’t a luxury, it’s a quality-of-life issue. Laminated glass combinations on the VLX 500 measurably reduce mid- and high-frequency noise. We’ve had clients in Westwood and Studio City tell us the difference after replacement was the first thing they noticed.
Airtightness & Weather Seal
Sealed against drafts and dust. The VLX 500’s interlocking meeting rails and compression weatherstripping create a positive seal when the sash closes. That matters in Los Angeles for two reasons: Santa Ana wind events that push air through weak seals, and the fine dust that blows in from the hills and canyons. A properly sealed aluminum system keeps both out.
Waterproofing
Perimeter water management. On installation, Westlight Windows & Doors applies AAMA 812 low-expansion foam sealant to every perimeter joint. We also flash the rough opening correctly before the unit goes in. Los Angeles doesn’t get much rain, but when a winter storm hits, a poorly flashed window will leak inside the wall cavity long before you see water on the interior sill. This is where proper installation matters as much as the product itself.
Wind Resistance
Rated for the local climate. The VLX 500 is wind-load rated for the requirements that apply across Los Angeles, including hillside exposure zones in the Hollywood Hills, Mount Washington, and the Palisades. The 0.079-inch extrusion thickness and multi-point locking hardware keep large panels from deflecting or rattling during heavy gusts. ViewLux builds this series to perform in wind conditions well beyond what a standard vinyl slider will handle.
Security & Hardware
Serious locks on a serious frame. The locking hardware on the VLX 500 engages into reinforced keepers in the frame, not flimsy plastic catches. Combined with the structural aluminum profile, this creates a window that resists forced entry far better than typical residential sliders. Impact-resistant laminated glass is available as a security upgrade, and it also provides a measure of protection against flying debris during wind events.
Color & Glass Options
Aluminum takes a finish differently than vinyl or wood. The powder-coated finishes on the VLX 500 are uniform, deeply saturated, and resistant to fading from the Los Angeles sun. Premium Black is our most requested finish for modern and contemporary homes in Los Angeles neighborhoods like Venice, Culver City, and Highland Park. It reads as sharp and architectural against white stucco or wood cladding. Pure White works beautifully on Spanish and traditional homes where the window should disappear into the wall. Anodized Silver is a classic commercial look that also suits industrial lofts in the Arts District.
Bronze and Champagne both lean warm and pair well with earth-toned exteriors, clay tile roofs, and mid-century wood trim. Teak Wood is a wood-grain powder coat that recreates the look of timber without the maintenance. We’ve installed that finish on several Los Angeles homes where the design intent was to match existing wood windows at a lower long-term cost.
For glass, Clear is the baseline. Low-E adds an invisible coating that reflects infrared heat while letting visible light through, which is worthwhile on any elevation that gets direct sun. Frosted glass is ideal for bathrooms or a hallway window where you want light without a view. Tempered glass satisfies safety-code requirements for windows near doors and low sill heights. Laminated glass is the upgrade we recommend for noise reduction and security, and it’s the best answer for Los Angeles homes near freeways or busy commercial corridors.
Installation by Westlight Windows & Doors in Los Angeles
Installing a high-performance aluminum window incorrectly is like buying a great engine and putting it in a car with no brakes. The product can be world-class, but if the rough opening isn’t prepped correctly, the frame isn’t set level and square, and the perimeter isn’t sealed properly, that window will underperform and the manufacturer warranty won’t cover the failure. ViewLux warranties apply to correctly installed units. That’s the single biggest reason Los Angeles homeowners choose Westlight Windows & Doors as their installation partner for the VLX 500.
Our process starts with a detailed pre-installation inspection. We measure the existing rough opening in three places, check the condition of the framing, and look for signs of water intrusion or dry rot. Los Angeles has a huge inventory of homes built between 1950 and 1980, and we’ve replaced windows in enough of them to know that the opening often isn’t square by the time we get there. That’s fine. We account for it.
During installation, we set every window level, plumb, and square before fastening. Then we seal the complete perimeter with AAMA 812 low-expansion foam sealant. We flash the head, jambs, and sill correctly. We install to AAMA 2400/2410 installation standards on every job, regardless of the project size. After the unit is in, we test the operation of every sash, we check the water barrier at the perimeter, and we clean the work area. When we leave, the window opens and closes like it should, and the site is cleaner than we found it.
Los Angeles building codes require specific attachment methods and water management details for window installation, and our crew is current on those requirements. Whether you’re in a hillside zone subject to increased wind loads or a coastal property with exposure to salt air in Playa del Rey or San Pedro, we’ll talk through material compatibility and hardware choices before the work starts.
Frequently Asked Questions - VLX 500 Sliding Window
Lead time for the VLX 500 is typically 3 to 6 weeks depending on finish, glass specification, and current factory production volume. Custom sizes and laminated glass add to the lead time. We place the order with ViewLux within 48 hours of signing, and we’ll keep you updated on the production schedule. If timing matters to your project, call (903) 354-7134 at the start so we can factor lead time into the plan.
Yes, when specified with qualifying Low-E glazing packages that meet current ENERGY STAR and federal energy tax credit requirements. Not every glass combination qualifies, so we’ll confirm eligibility on your specific build before you order. The credit is claimed on your federal taxes, not at the point of purchase. We’ll help you understand the paperwork and give you what you need to file.
The VLX 500 carries ViewLux’s manufacturer warranty on the frame, finish, and hardware, plus the glazing unit warranty on the glass. The warranty is only valid when the window is installed by an authorized partner like Westlight Windows & Doors. We are authorized ViewLux installers in Los Angeles, so your product warranty stays intact when we do the work.
The VLX 500 is offered in standard and custom sizes, and large openings are possible because the aluminum frame is structurally strong enough to span wide without sagging. We’ll measure the exact rough opening at your Los Angeles property and specify the right size, track configuration, and glass. This isn’t an off-the-shelf product you’re forcing into an opening, it’s built to fit your wall.
Aluminum frames need very little maintenance. Clean the powder-coated surface with mild soap and water, keep the track free of debris with a soft brush or vacuum, and lubricate the rollers once every year or two with a dry silicone spray. In coastal Los Angeles neighborhoods like Marina del Rey or Redondo Beach, wipe the frames down more often to keep salt residue from sitting on the finish. The finish is durable, but salt air is aggressive to any metal over the decades.
