Product Overview – VLX 500 Sliding Window

The VLX 500 is what happens when engineers strip an aluminum sliding window down to its essentials and then obsess over the details. The frame extrusion measures just 1.97 inches across the face, which means more daylight and a cleaner architectural line than you’ll get from standard residential aluminum. The track system is machined to glide smoothly, even on a 6-foot panel, so the sash moves with one hand and stays exactly where you stop it. Buyers in Pasadena tend to fall into two camps: those replacing old single-pane sliders in mid-century ranch homes, and those building or renovating modern homes where the window is as much design element as function. The VLX 500 answers both.

ViewLux manufactures the VLX 500 as part of its architectural aluminum line, and Juniper Windows Pasadena is authorized to sell and install the full series. That authorization matters. It means our installers have gone through the manufacturer’s technical training, we order glass packs directly from ViewLux’s production system, and every installation we perform in Pasadena carries the full manufacturer warranty without exception. We stock sample units at our Pasadena showroom so you can feel the glide and see the finish quality before committing.

Technical Specifications

The numbers below tell the story of a window engineered for both thermal performance and long service life in Southern California climates. We’ve pulled the key specs so you can compare against other aluminum and vinyl sliders you may be considering.

• Wall thickness: 0.079 inches on the frame extrusion. That’s heavier than most residential aluminum and resists flexing or bowing over a long sill span.
• Profile width: 1.97 inches across the visible frame face. Slim enough to disappear into a wall, deep enough to house the thermal break and hardware channel.
• Track configurations: Available in 2-track (two sashes, one fixed panel) and 3-track (three sashes, multi-panel operation, wider openings).
• Glass options: Clear, frosted, Low-E, tempered, and laminated. Mix and match across the unit if you want clear in one panel and frosted in another.
• Finish options: Premium Black, Pure White, Anodized Silver, Bronze, Champagne, and Teak Wood. Powder-coated on aluminum for even coverage and scratch resistance.
• Screen options: Retractable screen and traditional sliding screen, both fitted to the specific track configuration.
• Performance ratings: NFRC-rated with thermal break technology; tested for airtightness, water intrusion, and structural load per AAMA standards.

Performance Features

Thermal Efficiency. The VLX 500 uses a polyamide thermal break between the interior and exterior aluminum faces. That break interrupts the conductive path that makes standard aluminum frames feel hot in Pasadena summer and cold on winter nights. Combined with Low-E glass, the assembly earns NFRC energy ratings that qualify for utility rebate programs in Southern California.

Acoustic Performance. The 0.079-inch wall thickness and tight corner joinery reduce frame vibration, which is where most aluminum windows leak sound. Adding laminated glass takes noise reduction further, cutting traffic frequencies from the 210, Colorado Boulevard, and the Gold Line corridor. For bedrooms facing the street or a neighbor’s HVAC unit, this is the upgrade that matters most.

Airtightness & Weather Seal. The VLX 500 uses a dual-seal stack: a brush-pile interlock at the meeting stile and compression gaskets at the frame perimeter. Together they keep conditioned air inside the home and Pasadena dust outside. Our installers verify seal compression at every point before final trim goes on.

Waterproofing. The track sill includes a weephole system that routes water out of the frame rather than trapping it. On a Pasadena winter with heavy overnight rain, that drainage design is the difference between dry interior sills and warped laminate flooring. We also apply low-expansion foam sealant on every perimeter joint per AAMA 812, so water never travels behind the frame.

Wind Resistance. The heavier extrusion wall and reinforced corners let the VLX 500 meet wind-load requirements for Southern California exposure zones. That includes the sudden pressure shifts you get on hillside lots in Altadena-adjacent Pasadena neighborhoods where Santa Ana gusts get channeled between homes. If your lot sits high on the San Rafael Hills, this rating becomes non-negotiable.

Security & Hardware. The sliding panels ride on stainless steel rollers with a lock that engages multi-point along the meeting rail. The track itself resists lifting from the outside. Laminated glass adds impact resistance, making forced entry measurably slower. For ground-level windows or any slider near a side yard gate, the laminated option is worth the line-item cost.

Color & Glass Options

The finish and glass you choose changes how the VLX 500 performs and how it reads from the street and the inside.

Premium Black anchors a window visually on stucco and pairs naturally with black-framed doors and fascia on newer Pasadena builds. Pure White disappears into white trim on traditional Spanish and Craftsman homes. Anodized Silver has a machined, metal-forward look that works on true mid-century moderns, where aluminum was the original spec. Bronze and Champagne both sit warmer than silver: Bronze suits earthy exterior palettes on hillside homes, Champagne works where you want a subtle metallic presence without contrast. Teak Wood is a powder-coated wood-tone finish over aluminum, made for homes that want the warmth of wood without the maintenance of a wood frame.

On glass: clear is the default and the most affordable. Frosted delivers privacy for bathrooms and side yards without losing daylight. Low-E is the energy upgrade we recommend for any Pasadena window receiving direct afternoon sun, especially west-facing walls. Tempered glass meets residential safety code for large sliding panels and low sill heights. Laminated glass does double duty: it reduces sound transmission and holds together if struck. You can combine Low-E with tempered or laminated in a single panel.

Installation by Juniper Windows Pasadena in Pasadena

We’re not a referral service handing your project to a sub. Every VLX 500 we install in Pasadena is installed by our own crew, on our schedule, to our standard.

The process starts with a pre-install inspection. We check the rough opening for square, level, and plumb, verify the existing waterproofing condition, and measure in three places so the ordered unit fits without shimming gymnastics. A window ordered wrong by even a half-inch becomes a problem you live with for years. We don’t order until the opening is confirmed.

On install day, we set the frame level, plumb, and square, shimming as needed so the sashes travel true. Every perimeter joint gets AAMA 812-compliant low-expansion foam sealant, inside and out. We flash and seal the exterior per AAMA 2400/2410 installation practice, which is the standard ViewLux requires for warranty coverage and the standard that performs in Pasadena’s dry-to-downpour seasonal swings. Then we water-test the installation, run each sash through its full travel, and adjust the rollers so the glide is exactly what you felt on the showroom sample.

Pasadena’s climate is mild, but the sun is not. We see failed installations from other contractors where the sealant was skipped behind the bottom sill and the first winter rain came straight into the wall cavity. AAMA-compliant installation isn’t optional if you want the window to perform for 20 years. It’s also the only path to a warranty that actually pays out if something does fail.
