Product Overview – VLX 500 Sliding Window

The VLX 500 is an aluminum sliding window that prioritizes two things: how little frame you see and how easily the sash moves. The engineering story starts with aluminum. It’s the material spec home builders on the coasts have used for decades, but in Texas it’s having a serious moment because homeowners are tired of vinyl frames that flex, fade, and lose their seal after a few brutal summers. Aluminum holds its shape. The VLX 500’s profile width is just under two inches, so the glass-to-frame ratio leans heavily toward glass. That’s the architectural appeal: broad, uninterrupted views with a frame that reads as a thin line, not a bulky border.

The sliding mechanism uses precision rollers that carry the sash weight evenly across the track. You’ll notice it the first time you open it. No dead spots where the sash catches, no wobble mid-glide. It’s the kind of detail that separates a window you tolerate from one you actually enjoy using. In a Dallas living room or a second-floor bedroom that catches the evening breeze, that matters more than most people expect.

What makes this system genuinely versatile is the track count. The 2-track design gives you one fixed pane and one sliding pane, which is the classic layout for bedrooms, kitchens, and single openings. The 3-track version lets two panes slide while one stays fixed, which means you can open up to two-thirds of the width for airflow. That’s a real advantage in North Texas, where spring and fall evenings call for open windows and the summer demands them sealed tight.

Functionally, the VLX 500 covers all the bases buyers bring up: it will accommodate insect screens, it’s available with impact-resistant laminated glass, and it meets the thermal and structural performance standards we describe below. This is not an economy product. It’s a window for people who plan to stay in their Dallas home and don’t want to replace the windows twice.

Technical Specifications

Here’s what the VLX 500 brings on paper, in plain language:

• Wall thickness: 0.079 inches of aluminum extrusion. That’s heavier wall stock than you’ll find on most mid-tier aluminum windows, which contributes to frame rigidity over wide spans.
• Profile width: 1.97 inches. Slim enough to disappear architecturally, wide enough to house a thermal break and solid hardware.
• Track configurations: 2-Track (one fixed, one sliding) and 3-Track (two sliding, one fixed).
• Glass options: Clear, Frosted, Low-E, Tempered, Laminated. Mix and match per pane where code or privacy needs dictate.
• Finish options: Premium Black, Pure White, Anodized Silver, Bronze, Champagne, Teak Wood.
• Screen options: Retractable Screen (rolls away when not in use) and Sliding Screen (traditional screen track).
• Performance standards: NFRC-rated thermal performance, AAMA 2400/2410 installation standard compliance, AAMA 812 foam sealant at all perimeter joints, wind-load rated for Dallas-area requirements.

Performance Features

Thermal Efficiency
The VLX 500 frame uses thermal break technology, which separates the interior and exterior aluminum faces with a non-conductive material. This keeps the outside heat from conducting straight through the metal into your living room. Combined with Low-E glass, it earns NFRC energy performance ratings that matter for Dallas cooling bills, not just marketing brochures.

Acoustic Performance
Aluminum frames with properly bedded insulated glass perform well on sound control, and the VLX 500’s rigid frame holds the glass edge steady so the seal stays intact over time. If you live near a tollway, a freight rail line, or a busy arterial in Dallas, ask about laminated glass, which adds a noticeable layer of sound dampening.

Airtightness & Weather Seal
The weatherstripping on the VLX 500 is designed for compression sealing along the full sash perimeter. In practical terms, that means you won’t feel drafts at the meeting rail on a windy February day, and the window won’t whistle when the pressure changes. At Westlight Windows Dallas, we seal every perimeter joint during installation with AAMA 812 compliant low-expansion foam, which locks what the gaskets start.

Waterproofing
Sliding windows live or die by their track drainage. The VLX 500’s track design channels water out through weep holes rather than letting it pool against the sash. During installation, our crew in Dallas slopes the sill per manufacturer spec, tapes and foams the perimeter, and runs a water test before the trim goes back on. It’s the step that separates a 30-year window from a 5-year leak patch.

Wind Resistance
Dallas sees straight-line wind events and the occasional severe thunderstorm with gusts that will test a flimsy window. The VLX 500 is wind-load rated for local requirements, and the 0.079-inch wall thickness gives the frame the stiffness to resist deflection under load. For homes in exposed positions, the impact-resistant laminated glass option adds another layer of storm protection.

Security & Hardware
The sliding sash rides on a steel-reinforced track with locking hardware that engages at the meeting rail. Laminated glass, when selected, holds together on impact rather than shattering into large shards. It’s a security upgrade that also satisfies building code in some Dallas storm-zone designations without adding exterior bars or film that changes the view.

Color & Glass Options

The VLX 500 ships in six finishes: Premium Black, Pure White, Anodized Silver, Bronze, Champagne, and Teak Wood. The anodized finishes are not paint. They’re an electrochemical treatment that becomes part of the aluminum itself, so they won’t peel or chalk in the Dallas sun. The painted finishes, Premium Black and Pure White, use a baked-on process that holds its color far better than typical spray-applied coatings.

For design context: Premium Black and Anodized Silver read as modern and work well on contemporary homes in East Dallas or the Design District. Bronze and Champagne lean warmer and suit transitional or Mediterranean-influenced homes in Preston Hollow and Bluffview. Teak Wood gives you a warm organic tone that pairs nicely with more traditional exteriors or interiors where you want the window frame to carry a wood-like character without the maintenance of actual wood.

On glass: Clear is your baseline. Low-E is the Texas smart choice because it cuts solar heat gain through the glass, which is where most of your cooling load comes from. Tempered glass is safety glass, required by code in certain locations like near doors and low to the floor. Frosted gives you privacy without window film and works well for bathrooms or a front-facing bedroom in a dense Dallas neighborhood. Laminated handles impact resistance and sound control. Most of our clients pair Low-E with tempered or laminated depending on the opening.

Installation by Westlight Windows Dallas in Dallas

The strongest window on the market will still leak and fail if it’s installed wrong. That’s not a manufacturer’s excuse; it’s the reality of building physics. A window that isn’t set square will bind when you slide it. A perimeter that’s sealed with the wrong foam will let water find the rough opening. A sill flashing that’s taped wrong will rot a Dallas home’s framing in a decade. Improper installation voids the manufacturer warranty, which means all that product quality means nothing if the crew cuts corners.

Our process at Westlight Windows Dallas starts before we order anything. We measure the opening, check the wall condition, and verify the rough opening dimensions against what the VLX 500 requires. We look for existing water damage, rot, or out-of-square framing that needs to be addressed before the new window goes in. You don’t want a new window set into a bad opening.

During installation, we set every unit level, plumb, and square. That’s not a slogan; it’s the AAMA 2400/2410 standard we follow as our baseline for every job in Dallas. We shim and fasten per the manufacturer’s engineering, then seal the full perimeter with AAMA 812 compliant low-expansion foam. That foam does two jobs: it insulates the gap and it blocks air and water migration. Then we tape the exterior, set the sill to drain, reinstall the interior trim, and run a water test before we call it done.

Dallas-specific concerns show up in our pre-install checks. Homes here see big temperature swings, which means your rough opening has been moving for years. We check for that movement and account for it. If your home is in an older Dallas neighborhood like Lake Highlands or Casa View, the original framing may have settled into odd geometry. The VLX 500’s rigid aluminum frame does not flex to accommodate a sloppy rough opening, so prep work matters. We handle it. That’s the point of hiring a crew that installs this exact product line week after week.

Frequently Asked Questions – VLX 500 Sliding Window

What is the lead time for the VLX 500 Sliding Window?
Lead time runs roughly four to seven weeks from order confirmation to delivery at our Dallas shop, depending on glass type, finish availability, and the size of your order. Custom sizes and laminated glass can push toward the longer end of that range. Call (361) 441-0865 and we’ll give you a current lead time for your specific configuration before you commit.

Does the VLX 500 qualify for energy tax credits?
The VLX 500 with Low-E glass is designed to meet the energy performance requirements for federal window tax credits, but eligibility depends on your specific configuration and your home’s location. Your tax professional can confirm the credit applies, and we can provide the NFRC performance data for your exact window spec. Call (361) 441-0865 to discuss glass options that maximize both efficiency and potential credits.

What warranty comes with the VLX 500 Sliding Window?
The VLX 500 carries a manufacturer warranty from ViewLux, and the installation work by Westlight Windows Dallas is covered by our own written workmanship warranty. A properly installed window with a factory warranty means you’re covered on both the product and the labor that put it in. Get the full warranty details at your estimate. Call (361) 441-0865 to set that up.

Can I customize the VLX 500 to fit an unusual opening?
Yes. The VLX 500 is built to order, so we size each unit to your actual rough opening rather than forcing a stock size into your wall. We’ve fitted this series into standard Dallas builder openings, wide custom spans, and everything in between. The 2-track and 3-track options also let you decide how much of the opening you want to actually open. Call (361) 441-0865 and we’ll measure your opening before we recommend a configuration.

How do I maintain an aluminum window frame in Dallas?
Aluminum frames need very little maintenance. Clean the track with a dry cloth or a vacuum brush attachment a few times a year, especially after windy stretches when Dallas dust and pollen collect in the track. Wipe the frame with soapy water and a soft cloth; avoid abrasive pads on painted or anodized finishes. Check the weep holes on the exterior track are clear after heavy rain. That’s the whole routine. If anything ever feels rough or stiff when you slide the sash, call (361) 441-0865 and we’ll inspect it.
