Product Overview – VLX 500 Sliding Window

The VLX 500 is a high-performance aluminum sliding system with a slim profile and an effortless glide, available in 2-track and 3-track configurations. That’s the short version. The longer version is this: it’s designed for wide openings where you want maximum glass and minimum frame. Think living rooms that open to a backyard in Willow Glen, bedroom windows facing the foothills in Almaden Valley, or kitchen windows in Campbell that get opened and closed twenty times a day.

Aluminum gets a bad reputation in some circles because old aluminum windows were thermal sieves. This product is different. It uses thermal break technology to separate the interior and exterior metal, so you get aluminum’s strength and stiffness without the heat transfer problem. The frame won’t bow under heavy glass, the track won’t wear out from daily use, and the slim 1.97-inch profile width keeps sightlines unobstructed. Buyers choose this series when they want a modern look that performs like a serious piece of engineering, not a decorative afterthought.

For San Jose homeowners, the VLX 500 fits the architectural mix well. Our crews have installed it in mid-century ranchers in Willow Glen, new contemporary builds in North San Jose, and Spanish-style homes in the Rose Garden district. The 2-track configuration works for standard openings. The 3-track gives you more ventilation control with two operable sashes, which matters on summer days when the temperature swings thirty degrees between morning and afternoon.

Technical Specifications

The 0.079-inch wall thickness gives the frame structural rigidity without adding visual bulk. You get a straight, true frame line that holds its shape through San Jose’s seasonal temperature shifts. The 1.97-inch profile width is what keeps the glass area large relative to the frame, which is the point of choosing aluminum over vinyl or wood in the first place.

Performance Features

Thermal Efficiency. The VLX 500 uses a thermal break that separates interior and exterior aluminum, cutting conductive heat transfer. Pair it with Low-E glass and you have an NFRC-rated window that actually helps with San Jose summer cooling and winter heat retention, not one that fights your HVAC system.

Acoustic Performance. Laminated glass takes the edge off road noise, which matters if you live near Interstate 280, Highway 87, or a busy corridor like Stevens Creek Boulevard. The aluminum frame’s rigidity helps the seal stay tight, which keeps sound from sneaking around the edges.

Airtightness & Weather Seal. The track system is engineered so the sash seats firmly against the weatherstripping when closed. No rattles, no drafts, no dust infiltration during the dry, windy stretches that hit San Jose in the fall.

Waterproofing. Every install by Westlight Windows San Jose uses AAMA 812 low-expansion foam sealant on all perimeter joints. We don’t rely on caulk alone. Water that gets past the exterior cladding hits a properly sealed, properly flashed opening, which is what keeps stucco and drywall dry in a wet El Niño winter.

Wind Resistance. The VLX 500 is wind-load rated for local climate requirements. San Jose doesn’t get hurricane-force winds, but the exposed hillside homes in the East Foothills and the open stretches of South San Jose do see sustained gusts that flex flimsy frames. This one holds.

Security & Hardware. Impact-resistant laminated glass is available as an option, which matters for ground-floor windows and sliding doors. The track hardware is built for repeat cycles, so the sash doesn’t get sloppy over time. A window that closes tightly every time is a window that locks properly every time.

Color & Glass Options

The VLX 500 comes in six finishes: Premium Black and Pure White for contemporary and traditional homes respectively, Anodized Silver for the industrial-modern aesthetic that’s popular in downtown San Jose lofts and new builds, Bronze for a warmer metal tone that pairs well with Spanish and Mediterranean exteriors, Champagne for a soft, muted metallic that blends without disappearing, and Teak Wood for aluminum that reads as wood at a glance, which solves the HOA problem in neighborhoods that require wood-looking windows on street-facing elevations.

Glass starts with Clear for unobstructed views and maximum daylight. Frosted works for bathrooms, side yards, and anywhere a neighbor is too close. Low-E glass is the energy upgrade we recommend for any window that gets afternoon sun, which is most of San Jose from May through October. Tempered glass is available where code requires it, and Laminated glass adds both impact resistance and sound reduction. Screens are available as a retractable unit that hides when not in use or a standard sliding screen.

Installation by Westlight Windows San Jose in San Jose

Installation is where most window failures happen, and it’s the part we control completely. Here’s how we install VLX 500 windows across San Jose:

• Pre-install inspection. We check the rough opening, the framing condition, and the existing waterproofing before the window ever comes off the truck.
• Level, plumb, and square. Every unit is set with shims and checked with a laser. A window that’s even slightly out of square will bind the track and wear the rollers prematurely.
• AAMA 812 perimeter seal. Low-expansion foam sealant on all perimeter joints, taped and flashed on the exterior where the existing construction allows it.
• AAMA 2400/2410 standard compliance. This is the installation standard the industry points to. We follow it on every job in San Jose, from single-unit window replacements in Cambrian to full-house jobs in Evergreen.
• Final water test. We spray the exterior, watch the weep system, and verify drain paths before we clean up.
• Warranty protection. A manufacturer warranty on a great window is worthless if the window was installed wrong. Proper installation keeps your ViewLux warranty intact.

San Jose has its own wrinkle: a lot of homes here were built in the 1950s through 1980s with framing that’s moved, stucco that’s cracking, and openings that are anything but square. We deal with that. We also deal with the building codes in San Jose and surrounding cities, which matter when you’re changing window sizes or opening types, not just swapping like for like.

Frequently Asked Questions – VLX 500 Sliding Window

What is the lead time for the VLX 500 Sliding Window? Lead times for VLX 500 windows typically run 4 to 8 weeks depending on glass type, finish, and order size. Custom sizes don’t add much time because ViewLux manufactures to your dimensions anyway. Call us at (669) 333-7786 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? Low-E glass as configured in the VLX 500 may qualify for federal and California energy incentive programs, but qualification depends on the specific glass package, orientation, and your tax situation. We can point you toward the current program requirements for San Jose homeowners and help you choose a package that meets them if that’s a priority for you.

What warranty comes with the Sliding Window? ViewLux provides a manufacturer warranty on frame and glass, and Westlight Windows San Jose stands behind our installation work. The details of the warranty depend on the product line and glass package, but our installation warranty covers workmanship separate from the manufacturer warranty. We’ll put everything in writing in your contract, not in a handshake.

Can I customize the size? Yes, each VLX 500 window is fabricated to your opening dimensions. That’s how aluminum works: the frame is extruded and cut, not pulled from a stock size chart. Very wide openings may require a 3-track configuration or reinforced lintel support, but those are details we’ll address in your free on-site measurement.

How do I maintain aluminum frames? Wash the frame and track with mild soap and water, and vacuum the track monthly. Keep the weep holes clear so water drains. Lubricate the rollers with a silicone spray once a year. Aluminum frames don’t rot, warp, or require painting. Maintenance takes minutes a year, and the track design makes it easy to access. Need a replacement part down the road? Call us; we service what we sell in San Jose.
