Product Overview – VLX 500 Sliding Window

The VLX 500 is a high-performance aluminum sliding system in the truest sense: minimal frame, maximum glass, and a track system that lets a 100-pound sash move with one hand. It’s the series that architects specify when they want clean sightlines and nothing fussy. The profile width comes in at just 1.97 inches, which is noticeably slimmer than older thermally-broken aluminum sliders from the 90s and early 2000s. That slimness shows up where it matters: more daylight, less metal blocking your view of the backyard, the pool, the foothills.

Buyers in Fresno choose this series for two reasons. First, it looks current without being trendy. The lines are quiet and horizontal, which suits the low-slung ranch homes in Fig Garden and the newer builds in Clovis and Northwest Fresno equally well. Second, it solves the two problems Fresno homeowners complain about most with sliders: frames that stick when it’s hot, and tracks that collect dirt and grit. The VLX 500 is designed so the sash rides on precision rollers that stay true over years of daily use. Aluminum doesn’t rot, doesn’t absorb moisture, and doesn’t require the maintenance wood or vinyl inevitably demands in this climate.

It’s available in two track configurations. The 2-track is the classic slider: one fixed panel, one gliding panel. The 3-track lets you open up a wider span with two gliding sashes and lets more air move through. That matters in Fresno, where evening delta breezes are the most natural cooling system we have.

Technical Specifications

Here’s the VLX 500 broken down into the numbers and options that show up on an order form.

• Frame material: Architectural-grade aluminum with thermal break technology
• Wall thickness: 0.079 inches, which gives the frame structural rigidity without adding visual bulk
• Profile width: 1.97 inches, one of the slimmest thermally-broken profiles in its class
• Track configurations: 2-track (one fixed, one sliding) or 3-track (two sliding, one fixed)
• Glass options: Clear, Frosted, Low-E, Tempered, Laminated
• Finish options: Premium Black, Pure White, Anodized Silver, Bronze, Champagne, Teak Wood
• Screen options: Retractable screen or standard sliding screen
• Performance ratings: NFRC-certified thermal performance, AAMA 2400/2410 installation compliance, impact-resistant laminated glass available, wind-load rated for Central Valley requirements

Every measurement on this list matters. The 1.97-inch profile width, for instance, is what allows a larger glass area in the same rough opening as an older bulkier frame. That’s square inches of natural light you’re getting back. Call (559) 272-9650 with your rough opening dimensions and we’ll confirm pricing and lead time on the spot.

Performance Features

Thermal Efficiency – The VLX 500 frame uses a true thermal break, not a cosmetic one. That’s the polyamide strip separating the interior and exterior aluminum, and it’s what stops Fresno summer heat from conducting straight through the metal and into your living room. Combined with Low-E glass, the system earns NFRC ratings that hold up in our climate zone. Expect a measurable difference on the August power bill.

Acoustic Performance – If you live near the 41, the 180, McKinley Avenue, or any of Fresno’s city arteries, you already know that road noise is a quality-of-life issue. The VLX 500’s multi-chamber frame and tight sash-to-frame seal cut a meaningful amount of mid-range noise. Laminated glass pushes that damping further, and it’s an option we routinely recommend for homeowners close to traffic or train crossings.

Airtightness & Weather Seal – Air leakage is what makes a room drafty in winter and is the quiet reason your HVAC runs more than it should. The VLX 500 is engineered with stacked weatherstripping at the interlock and sill. In practical terms, you don’t feel air moving around a closed sash. That’s the test we do on every job before we leave the site.

Waterproofing – Every VLX 500 we install in Fresno gets perimeter sealing per AAMA 812, using low-expansion foam sealant at all joints, plus carefully tooled sealant at the transitions where frame meets stucco, siding, or brick. Water is the enemy of every rough opening. The window itself sheds water well; the installation is what keeps it out of the wall cavity for decades.

Wind Resistance – Fresno’s worst wind events blow in off the Sierra in spring and out of the north in winter. The VLX 500 is wind-load rated for local requirements, which matters when a slider is two panels wide and eight feet tall. The frame’s 0.079-inch wall thickness and the interlocking meeting rails are what keep the sash from chattering or flexing when gusts slam the building envelope.

Security & Hardware – Sliding windows sit low, and anyone weighing home security looks at them first. The VLX 500’s sliding sash locks at the jamb with a cast hardware point, and the optional laminated glass adds a security layer that also meets impact-resistance standards. We can also add a secondary locking pin for extra peace of mind, especially on ground-floor bedrooms and back-of-house installations.

Color & Glass Options

Six finishes cover most of what we see requested in Fresno. Premium Black reads as modern and works on new-construction homes with dark window trim, black fascia, and contemporary hardscaping. Pure White is the classic Fresno choice for traditional stucco ranches. Anodized Silver has a slightly raw, aluminum-honest look that fits mid-century and commercial-to-residential conversions. Bronze sits between black and silver, warmer than black and less reflective than silver. Champagne is a lighter warm metallic that softens the frame visually. Teak Wood is a wood-grain textured powder coat that reads as stained wood from ten feet and as metal up close, which makes it the option we suggest to customers who like wood’s warmth but don’t want wood’s maintenance or cost in the Central Valley’s dry heat.

On glass: Clear is the budget baseline. Frosted works where you want privacy without a window treatment, like bathrooms and side yards. Low-E is the energy-performance upgrade, something we consider standard advice for west-facing and south-facing sliders in Fresno. Tempered glass meets safety-glazing code for doors and adjacent panels. Laminated adds impact resistance, sound damping, and a defensive layer at the home’s accessible points. You can pair most glass types with any finish.

Installation by Lightwell Windows Fresno in Fresno

Here’s the part of the page that matters as much as the product: a window’s performance in the real world is about half product and half installation. The VLX 500 is engineered to hit its ratings when it’s installed square, level, plumb, and sealed the right way. Improper installation does more than void the manufacturer’s warranty. It creates air gaps, water intrusion, and operational problems that don’t show up until the first heavy rain or the first 105-degree week.

Our process on every Fresno job starts with a pre-install inspection of the rough opening. We check the framing, the condition of the existing flashing, and the substrate for dry rot or termite damage, which is common in older Fresno neighborhoods like Tower District and Sunnyside. Then we set the frame plumb and square in both directions, shimming at the anchor points exactly where the manufacturer specifies. The frame is fastened through the jambs and head, never through the sill, which keeps the track from bowing and the sash from binding. That’s the detail that separates a window that glides for fifteen years from one that fights you after two.

All perimeter joints follow AAMA 812, filled with low-expansion foam that seals the gap between the frame and rough opening without distorting the frame. We then install per the AAMA 2400/2410 installation standard, which covers the full rough-opening retrofit and new-construction sequence. The interior is sealed for airtightness, the exterior is sealed and flashed for waterproofing, and then we run a water test on the sill and head before trim goes back on. After that, we clean the site. The window works, the wall drains, and the only thing left for you to do is open the slider and let the evening air through.

We know the city. We know Fresno’s permitting path for window replacement, and when a job triggers a local building code requirement, we pull the permit and schedule the inspection. That’s part of working with a contractor who has years of local installs under our belt. Call (559) 272-9650 to talk through your opening sizes and project plan.

Frequently Asked Questions – VLX 500 Sliding Window

What is the lead time for the VLX 500 Sliding Window? Lead times typically run 3 to 5 weeks from order placement to delivery at our Fresno shop, depending on the glass pack, finish, and track configuration you choose. Custom sizes and laminated glass can push toward the longer end. Call (559) 272-9650 with your rough opening dimensions and we’ll confirm a date range before you commit.

Does the VLX 500 qualify for energy tax credits? Yes, in many cases. The VLX 500 with Low-E glass and the correct NFRC ratings can qualify for federal energy efficiency tax credits, depending on the configured U-factor and SHGC values and your tax situation. Your tax professional makes the final call, but the NFRC label on the unit is what they’ll want to see, and ours is printed on every window we install in Fresno.

What warranty comes with the Sliding Window? The VLX 500 carries a ViewLux manufacturer’s warranty on the frame, glass, and hardware, and our installation workmanship is covered by Lightwell Windows Fresno’s own guarantee. One thing to understand clearly: if the window is installed by someone who doesn’t follow ViewLux’s approved installation methods, that factory warranty is void. That’s a strong argument for hiring an authorized partner like us.

Can I customize the size? Yes. The VLX 500 is made to order, which means every window is cut to the exact rough opening of your home, not mass-produced in a few stock sizes. We handle the measuring and ordering so the size is right the first time, which is essential when you’re dealing with older Fresno homes where openings are rarely perfectly square or standard. Call (559) 272-9650 and we’ll measure it precisely.

How do I maintain aluminum frames? Aluminum is the lowest-maintenance frame material you can buy in the Central Valley. Wipe the frame and track with a damp cloth every few months, clean the track of dust and debris so the rollers stay smooth, and don’t use abrasive cleaners. If the track picks up grit or pet hair, use a vacuum with a brush attachment. The roller assemblies can be accessed for occasional lubrication. But you don’t paint, stain, or seal anything. That’s the point.
