Product Overview – VLX 500 Single & Double Hung Window

The VLX 500 is what most people picture when they think of a classic double hung window: two sashes stacked vertically, each gliding on its own track. What separates this series from cheaper aluminum windows is the engineering behind the frame. The profile width is 2.36 inches, slim enough to maximize glass area but deep enough to carry a real thermal break. Wall thickness runs 0.079 inches, which gives the frame torsional rigidity without adding visual bulk.

ViewLux designed this series for homes where windows are a working part of the house, not a decorative afterthought. In San Jose’s older neighborhoods like Willow Glen, Naglee Park, and the Rose Garden, we see the VLX 500 specified on remodeled Craftsman and Spanish Revival homes because the clean aluminum lines read as modern without clashing with traditional trim. In newer builds in Berryessa and Evergreen, it shows up in contemporary stucco and panel facades where the slim profile keeps the architecture crisp.

Both sashes tilt inward for cleaning. That matters more than people expect. A second-story window that can’t be cleaned from inside means a ladder, a hose, or years of hard-water spots from San Jose’s mineral-heavy municipal supply. The tilt mechanism on the VLX 500 is balanced, so releasing the sash and pulling it toward you doesn’t require fighting a heavy panel. We walk every client through it at installation, and most tell us it takes one try to get the feel.

Performance Features

Thermal Efficiency – The VLX 500 frame carries a polyamide thermal break that separates the interior and exterior aluminum faces. Aluminum conducts heat fast, which is why cheap aluminum windows sweat in winter and bake in summer. The break interrupts that transfer path. Pair it with Low-E glass and the assembly earns NFRC ratings that matter for San Jose’s Title 24 energy requirements and for keeping PG&E bills predictable through July and August heat waves.

Acoustic Performance – Homes near Highway 87, 280, or the Caltrain corridor deal with real noise. A double hung window is only as quiet as its seals. The VLX 500 runs interlocking meeting rails and compression weatherstripping along both sashes, which cuts the air-leak noise paths that cheaper windows ignore. Laminated glass steps it up further, taking the edge off traffic roar and the light-rail hum through downtown San Jose.

Airtightness & Weather Seal – Air leakage is where most hung windows fail over time. The VLX 500 uses continuous weatherstripping on the frame perimeter and between sashes, not foam tape that flattens after a season. The tested airtightness rating means fewer drafts around the window cavity, less dust infiltration during Santa Clara County’s dusty late-summer months, and less load on your HVAC.

Waterproofing – Windows in San Jose get hit with real rain a few times a year, and when it comes, it’s often wind-driven. The VLX 500’s sill design channels water outward through weep slots rather than pooling it against the frame. Combined with our AAMA 812 foam-sealed perimeter installation, the assembly resists water penetration even in exposed west-facing walls that catch the brunt of winter storms.

Wind Resistance – The 0.079-inch wall thickness isn’t a random number. It gives the frame the stiffness to hold its shape under gust loads with larger openings. We’ve installed VLX 500 units in homes along the Diablo Range foothills where afternoon winds funnel through the passes hard. The wind-load rating, combined with proper anchoring by our installers, means the sash doesn’t rattle or deflect when the pressure spikes.

Security & Hardware – The VLX 500 comes with a cam-action lock at the meeting rail and optional secondary locks for ground-level openings. Tempered or laminated glass is a smart upgrade for first-floor windows and doors in San Jose, where break-ins through windows remain the most common entry point in residential burglaries. Laminated glass holds together when struck, buying time and making forced entry significantly harder.

Color & Glass Options

The VLX 500 comes in six finishes. Premium Black is our best-seller in San Jose right now, especially on remodeled mid-century homes in Cambrian and Campbell-adjacent neighborhoods where black frames against white stucco or wood siding reads as intentional. Pure White works on traditional exteriors, keeping window openings from visually receding. Anodized Silver is the honest-aluminum look, durable and low-maintenance, common on commercial-to-residential loft conversions downtown. Bronze pairs with warm earthy stucco tones common in Almaden Valley. Champagne suits homes with beige or taupe color palettes. Teak Wood is a wood-grain finish for homeowners who want the look of wood without the repainting cycle.

On glass, Clear maximizes light. Frosted gives privacy for bathrooms and street-facing bedrooms without curtains. Low-E is the energy play, reflecting heat while passing visible light, and we recommend it on any San Jose elevation that takes direct afternoon sun. Tempered meets code for windows near doors and low sill heights. Laminated adds impact resistance and serious sound reduction, made from two panes bonded with an interlayer.

Half-Screen and Full Screen options cover insect season without blocking the view the rest of the year. Full screens make sense for bedrooms where you want ventilation all night. Half screens suit living areas where the lower half gets the breeze and the upper half stays visually open.

Installation by Westlight Windows San Jose in San Jose

Buying a quality window is half the equation. A VLX 500 installed wrong leaks, binds, and voids the manufacturer warranty. That’s why we handle every step ourselves, with our own crew, never subcontractors.

Our process starts with a pre-installation inspection. We measure the rough opening, check for rot or water damage in the surrounding framing, and verify the wall’s condition before any window comes off the truck. In San Jose’s older housing stock, especially pre-1980 homes in the Rose Garden and Naglee Park, we regularly find dry rot behind old window flanges that needs addressing before a new unit goes in.

We set every VLX 500 level, plumb, and square. Hung windows are unforgiving: a frame that’s out of square by even 3/16 of an inch will bind the sash or leave a light gap at the meeting rail. We shim until the frame is dead on, then anchor it per the manufacturer’s fastening schedule.

Every perimeter joint gets AAMA 812 low-expansion foam sealant. This matters in San Jose because our temperature swings, from mid-30s winter mornings to triple-digit summer afternoons, cause building materials to expand and contract. Cheap caulk cracks. Low-expansion foam fills the gap and flexes without losing adhesion. We also flash and seal the exterior perimeter, then run a water test on the installation before finishing interior trim.

We install to the AAMA 2400/2410 standard, which covers installation quality for windows in both residential and light commercial applications. The manufacturer warranty stays intact because the installation meets their specifications. You get one point of contact from measurement to final cleanup. We haul old windows and job debris, and we leave the room as if we hadn’t been there.
