AfterVLX 500 Single & Double Hung Window in Los Angeles, CA | Sightline Windows & Doors
The VLX 500 Single & Double Hung Window is a vertical-glide aluminum window built for homeowners who want classic styling without the maintenance headaches of wood. The sashes tilt inward, which means you can clean both sides of the glass from inside your house. No ladders, no squeegees on a pole, no hiring someone twice a year. Sightline Windows & Doors is an authorized ViewLux installation partner serving Los Angeles, CA, which means you get the product warranty backed by a local team that stands behind the install. If you’re pricing out a window replacement project in Los Angeles, call us at (509) 265-6387 for a free estimate.
Product Overview - VLX 500 Single & Double Hung Window
The VLX 500 is ViewLux’s take on the classic American hung window, re-engineered in aluminum. Both the top and bottom sashes slide vertically, and each one tilts inward for easy access to the exterior glass. For single-story Los Angeles homes, ranch-style builds, or any project where you want ventilation from top and bottom, this series fits the bill.
What sets the VLX 500 apart from vinyl hung windows is the frame material. Aluminum holds its shape through decades of sun exposure, won’t warp in the dry heat of the San Fernando Valley, and doesn’t expand and contract the way vinyl does during the cool coastal mornings and hot afternoons common across Los Angeles. The extrusion profile measures 2.36 inches wide with a 0.079-inch wall thickness, which gives the window real structural rigidity without looking bulky. Sightline has installed these in neighborhoods from Silver Lake to Mar Vista, and the feedback we hear most is about how smoothly the sashes glide even years after installation.
This window makes the most sense for homeowners replacing older aluminum sliders or failing wood double-hungs, especially in homes where window cleaning has been a chore. The tilt-in feature is the practical selling point. Buyers also choose the VLX 500 when they want a slim frame that maximizes glass area, because aluminum lets you get more visible glass in the same rough opening compared to vinyl.
Technical Specifications
Numbers matter when you’re comparing windows side by side. Here’s what the VLX 500 brings to the table, in plain terms:
- Frame construction: Aluminum extrusion with a 0.079″ wall thickness and a 2.36″ profile width.
- Glass options: Clear, Frosted, Low-E, Tempered, and Laminated. Any glass option can be combined with Low-E coatings for energy performance.
- Finish options: Premium Black, Pure White, Anodized Silver, Bronze, Champagne, and Teak Wood (a powder-coated wood-grain look).
- Screen options: Half-screen and full-screen configurations, depending on how much of the opening you want ventilated.
- Hardware: Locking mechanisms rated for daily use, designed to resist the salt air corrosion we see in coastal Los Angeles neighborhoods like Playa del Rey and San Pedro.
- Thermal performance: Built with a thermal break to separate the interior and exterior aluminum, which is what makes the NFRC-rated energy numbers possible.
BeforeAfterPerformance Features
Thermal Efficiency - The VLX 500 uses thermal break technology, which inserts a non-conductive barrier between the interior and exterior aluminum frames. That break is what stops heat from conducting through the metal. In Los Angeles, where summer temperatures regularly push past 90°F in the Valley, a thermally broken frame keeps your cooling costs from leaking out the window frame itself. NFRC-rated performance means the numbers are independently verified, not just marketing claims.
Acoustic Performance - If you live near the 405, the 110, or under a flight path into LAX, sound control isn’t optional. The VLX 500’s aluminum construction, combined with laminated glass options, significantly cuts exterior noise. Laminated glass uses an interlayer that dampens sound transmission. We’ve had customers in Westchester and Inglewood tell us the difference after installation was immediate and dramatic.
Airtightness & Weather Seal - Drafty windows are the enemy of comfort and energy bills. The VLX 500 is designed with a continuous weather seal around the sash perimeter that compresses when the window locks, cutting air infiltration. That seal is what keeps conditioned air inside and the dry, dusty Santa Ana winds outside.
Waterproofing - Proper installation is what makes a window waterproof, not just the window itself. Sightline applies AAMA 812-certified low-expansion foam sealant on all perimeter joints, then integrates the window with the building’s weather barrier system. The VLX 500 is built to shed water through its drainage channels, but the perimeter sealing is what keeps water from ever reaching the interior of your Los Angeles home.
Wind Resistance - Wind-load ratings matter in Los Angeles, especially for hillside homes in areas like Mount Washington or properties facing the Santa Monica foothills where gusts channel through canyons. The VLX 500 is wind-load rated for local climate requirements, meaning the frame, hardware, and glass system are engineered to hold together under pressure.
Security & Hardware - The VLX 500 comes standard with a robust locking system. Tempered and laminated glass options add another layer of security. Laminated glass, in particular, resists impact and holds together even when struck, which is why it’s also the glass option we recommend for impact resistance in Los Angeles homes concerned about break-ins or earthquake-related glass shatter.
Color & Glass Options
The VLX 500 comes in six finish options. Premium Black is our most popular choice for modern and contemporary homes, especially the updated mid-century builds popping up in neighborhoods like Eagle Rock and Highland Park. Pure White works beautifully on traditional and Spanish-style homes, matching the stucco and trim aesthetics common throughout Los Angeles. Anodized Silver is a classic aluminum look that fits commercial spaces and industrial-style remodels. Bronze and Champagne are mid-tone options that hide dust well and pair nicely with warm exterior palettes. Teak Wood is a powder-coated finish that mimics the look of wood grain, giving you the appearance of a wood window with none of the rot, termite, or repainting concerns that wood brings in the Los Angeles climate.
On the glass side, Clear is the budget-conscious option. Frosted works for bathrooms, street-facing windows, or anywhere privacy matters. Low-E glass is what we recommend for most Los Angeles homes because it reflects heat back outside during the summer while still letting natural light in. Tempered glass meets safety code requirements for windows near doors and low to the floor. Laminated glass is the top choice for sound control, impact resistance, and UV protection.
Installation by Sightline Windows & Doors in Los Angeles
The best window underperforms when it’s installed incorrectly, and the worst-case scenario is a voided manufacturer warranty. That’s the part most homeowners don’t think about until something goes wrong. ViewLux warranties cover manufacturing defects, not installation errors. A window that leaks because it wasn’t flashed correctly, or a sash that binds because the frame was set out of square, is not a product defect, it’s an installation problem, and no manufacturer covers that.
That’s exactly why Sightline Windows & Doors handles every VLX 500 installation according to AAMA 2400/2410 standards. Our process starts with a pre-installation inspection of the rough opening. We check the framing condition, look for existing water damage or rot, and verify the opening dimensions before the new window ever arrives on site. When the window goes in, we set it level, plumb, and square, then shim it properly so the frame doesn’t flex when the sashes operate.
Perimeter sealing is done with AAMA 812-certified low-expansion foam, which fills gaps completely without expanding enough to bow the frame. After the window is secured and sealed, we run a water test to confirm the installation is watertight, then clean up the job site before we leave. For Los Angeles homeowners, proper installation also means accounting for the city’s building codes and permit requirements where applicable. We handle permits and inspections when the job requires them, and we’re familiar with the variations in code enforcement across different LA neighborhoods.
Frequently Asked Questions - VLX 500 Single & Double Hung Window
Lead time for the VLX 500 typically runs 3 to 6 weeks from order confirmation to delivery in the Los Angeles area, depending on glass configuration and finish availability. Custom sizes and laminated glass options can add a week or two. Call (509) 265-6387 and we’ll give you a current estimate based on your specific order.
The VLX 500 can qualify for energy tax credits when configured with Low-E glass that meets the current Energy Star requirements for the Southern California climate zone. Eligibility depends on the specific glass package and your tax situation, so we recommend confirming with a tax professional. We’ll help you understand which glass options meet the efficiency thresholds.
ViewLux provides a manufacturer’s warranty on the VLX 500 covering defects in the frame, hardware, and sealed glass units. The exact terms depend on the glass package and finish selected. Installation warranty is provided separately by Sightline Windows & Doors. We recommend reviewing both warranty documents before your project starts, and we’re happy to walk you through them when we quote your job.
Yes, the VLX 500 is built to order in custom sizes to match your existing rough openings or your architect’s specifications. That’s one of the advantages of aluminum over stock vinyl windows, which force you to adapt your opening to standard sizes. We measure every opening on site during the free estimate so your windows fit precisely. Call (509) 265-6387 to schedule a measurement.
Aluminum frames need almost no maintenance beyond occasional cleaning with mild soap and water. Unlike wood, there’s no repainting, sealing, or caulking on your end. Keep the tracks free of debris and wipe them down a couple times a year. The tilt-in sashes make the glass easy to clean, and the powder-coated finishes won’t fade or chalk the way painted wood does in the Los Angeles sun. If you have questions about caring for a specific finish or hardware component, call us and we’ll talk you through it.
