Product Overview – VLX 138 Panoramic Sliding Door

The VLX 138 exists for one reason: to erase the line between your living room and the Riverside outdoors. The engineering goal here is maximum glass, minimum frame. With a profile width under two inches, the panels read as thin vertical lines between sheets of glass, so when the door is closed you still get a nearly uninterrupted view of your yard, your pool, or the Santa Ana River hills beyond.

The frame is extruded aluminum with a wall thickness of 0.138 inches, which gives it the structural confidence to span wide openings without bowing or sagging over time. That matters in Riverside, where summer heat can reach triple digits and aluminum expands and contracts daily. The VLX 138’s engineering accounts for that thermal movement, which is one of the reasons it rides so smoothly year after year.

What sets this door apart from standard sliders is the track system. The panels roll on precision stainless bearings, not plastic rollers, which is why a 300-pound glass panel feels like it weighs ten when you push it. There’s no grinding, no stutter, no “two hands and a hip” moment. You open it with one finger. That’s the detail people notice when they visit a friend’s house and can’t stop talking about the door.

Buyers choose the VLX 138 when they’re doing serious architectural work: a full rear wall replacement in Canyon Crest, a great room addition in Orangecrest, or a pool-to-patio connection in Victoria. It’s not a builder-grade sliding door. It’s a statement piece that also happens to function beautifully. Westlight Windows Riverside has installed VLX 138 doors across Riverside County, and we’ve seen what they do to a room. The room gets bigger. The house feels more expensive. And the view becomes the whole point of the house.

Technical Specifications

Here’s what you’re working with on the VLX 138 Panoramic Sliding Door. These are the numbers we quote from when a Riverside client asks us for a door that can handle a 36-foot opening or a specific glass package.

• Frame wall thickness: 0.138 inches, extruded aluminum construction
• Profile width: 1.535 inches, slim sightlines for maximum glass area
• Maximum span: Up to 36 feet wide across the full opening
• Track configurations: 2-track, 3-track, and 4-track layouts depending on how many panels you want and which way they should stack
• Glass options: Clear, Low-E, Frosted, Obscure, Black Tint, and Gray Tint
• Finish options: Premium Black, Pure White, Anodized Silver, Bronze, Champagne, and Teak Wood finish
• Screen options: Retractable screen that disappears into the frame, or a traditional sliding screen panel
• Sill options: Flush sill for zero-threshold transitions, low-profile sill for weather resistance with a minimal step, or recessed sill that drops into the floor for true indoor-outdoor continuity
• Performance standards: Thermal break technology, NFRC-rated energy performance, AAMA 2400/2410 compliant installation, AAMA 812 low-expansion foam on all perimeter joints

Every VLX 138 we order for Riverside homes is configured to the opening, the exposure, and the design intent. There is no one-size-fits-all version of this door.

Performance Features

Thermal Efficiency. The VLX 138 frame uses thermal break technology that separates the interior and exterior aluminum, stopping heat transfer through the metal. In Riverside’s summer, that’s the difference between a door that radiates heat into your living room and one that keeps your A/C bill under control. NFRC-rated performance means you can compare actual numbers, not marketing claims.

Acoustic Performance. Riverside isn’t quiet everywhere. If you live near the 91, the 215, or a busy surface street, sound control matters. The VLX 138’s sealed glass units and perimeter weatherstripping knock down exterior noise measurably. Laminated glass takes it further, which is worth considering for master bedrooms and home offices.

Airtightness & Weather Seal. Santa Ana winds find every gap in a house. The VLX 138’s full-perimeter gaskets and interlocking panel seals keep conditioned air inside and dust outside. When Westlight Windows Riverside installs the door, every joint gets AAMA 812 low-expansion foam sealant, which fills voids without warping the frame.

Waterproofing. A wide sliding door is a big hole in your wall, and Riverside does get real rain in the winter months. The VLX 138’s sill design channels water away from the interior, and the drainage paths are integral to the frame, not an afterthought. We install per AAMA 2400/2410 standards so the flashing and sill pan hold up through years of storms.

Wind Resistance. Riverside’s wind loads are a factor on exposed hillsides and canyon-adjacent lots. The VLX 138 is wind-load rated for the local climate requirements, and impact-resistant laminated glass is an option for extra structural integrity and safety. That’s a real consideration for anyone up in Mockingbird Canyon or along the Box Springs foothills.

Security & Hardware. The stainless bearing system isn’t just smooth, it’s durable. The multi-point locking hardware engages at multiple points along the panel height, not just a single latch at the handle. Combined with the aluminum frame’s rigidity, that makes forced entry genuinely difficult. Obscure or frosted glass adds privacy for ground-floor installations facing a street or neighbor.

Color & Glass Options

The finish you choose changes the whole personality of the door. Premium Black is the pick for modern farmhouse and contemporary Riverside builds; it reads sharp against white stucco and light hardscape. Pure White disappears into white walls and trim, which is ideal if you want the glass to be the only thing you notice. Anodized Silver is the classic aluminum look, honest and industrial, and it works beautifully on mid-century homes in the Wood Streets and Palm Heights.

Bronze and Champagne lean warmer. Bronze suits Spanish and Tuscan-inspired homes with tile roofs and wrought iron details, which describes a good portion of Riverside’s housing stock. Champagne is softer, a warm neutral that bridges modern and traditional without shouting. Teak Wood finish brings an organic texture to the metal, and it’s a smart choice for Craftsman and ranch-style homes where wood trim and built-ins are part of the design language.

On the glass side, Clear gives you true color and maximum light. Low-E is the energy play, and we recommend it on any west-facing or south-facing Riverside exposure. Frosted and Obscure glass give you privacy without curtains, useful for bathrooms, bedrooms, and street-facing panels. Black Tint and Gray Tint reduce glare and heat gain while adding a sleek, dark exterior look that pairs especially well with Premium Black frames.

Installation by Westlight Windows Riverside in Riverside

We’ve said it before and we’ll keep saying it: a great door installed badly is a bad door. The VLX 138 Panoramic Sliding Door depends on installation precision. The tolerances are tight. If the opening isn’t level, plumb, and square, the panels won’t glide right, the seals won’t compress evenly, and the manufacturer’s warranty won’t cover the results. That’s the blunt truth.

Westlight Windows Riverside installs every VLX 138 according to AAMA 2400/2410 installation standards. That starts with a pre-install inspection of the rough opening. We check the substrate, the flashing condition, and the structural framing before the door ever comes off the truck. Then we set the frame level, plumb, and square using shims and fasteners spec’d for Riverside’s construction types, which range from 1950s wood framing to modern steel and CMU.

Every perimeter joint gets AAMA 812 low-expansion foam sealant, which is the standard that prevents air and water infiltration without exerting pressure on the frame. After the panels go in, we run a water test on the sill and check the drainage channels. Then we adjust the rollers and locks so the door glides the way ViewLux engineered it to. Cleanup is part of the job, not an add-on. You get your new door and a clean job site.

Riverside’s climate demands this level of care. The heat cycling, the Santa Ana winds, the occasional heavy rain, and the dust all test a sliding door. A properly installed VLX 138 takes that abuse for decades. A sloppy install shows its flaws within the first year. If you’re spending five figures on a panoramic door, the installation is the wrong place to cut corners. Call (760) 624-3669 and we’ll walk you through what a proper install looks like.

Frequently Asked Questions – VLX 138 Panoramic Sliding Door

What is the lead time for the VLX 138 Panoramic Sliding Door? Lead time typically runs 6 to 10 weeks from order confirmation to delivery at our Riverside shop, depending on the glass package and finish configuration. Custom sizes and impact-rated laminated glass can add time. We’ll give you a written timeline when we quote your project, and we coordinate the installation date to match the delivery window.

Does the VLX 138 qualify for energy tax credits? The VLX 138 can qualify for federal energy tax credits when configured with Low-E glass that meets the current NFRC performance thresholds. Qualification depends on the specific glass package and your project details, so we recommend checking with your tax preparer. We’ll provide the NFRC-rated documentation for your specific door configuration. Call (760) 624-3669 for details.

What warranty comes with the Panoramic Sliding Door? The VLX 138 carries a manufacturer warranty from ViewLux, and the warranty is valid only when the door is installed by an authorized partner using AAMA-compliant methods. Westlight Windows Riverside is an authorized installation partner, and our workmanship is backed by our own installation warranty as well. We’ll walk you through the warranty terms before you sign anything.

Can I customize the size? Yes. The VLX 138 is built to order, not pulled from stock. That means every panel width, height, and track configuration is matched to your specific opening, up to the 36-foot maximum span. We field-measure every Riverside project before ordering, so the door arrives sized correctly for your actual rough opening, not a guess from blueprints.

How do I maintain aluminum frames? Wash the aluminum with mild soap and water twice a year, wipe the tracks clean of dust and grit, and check the drainage channels for blockages. Riverside’s dry climate means less grime than coastal areas, but wind-driven dust settles in the track over time. The stainless bearings don’t need lubrication, but the track needs to stay clean so the rollers don’t pick up abrasive debris. We cover maintenance in a walkthrough when we hand over the door.
