Product Overview – VLX 500 Single & Double Hung Window

The VLX 500 belongs to a category many Pasadena homeowners already know: the classic hung window. It slides up and down on a vertical track. A single hung means the bottom sash moves. A double hung means both sashes move, top and bottom, which gives you ventilation control from either opening. What makes the VLX 500 worth a closer look is the way ViewLux engineered the aluminum frame to feel solid without looking heavy. The profile width comes in at a trim 2.36 inches, which keeps sightlines slim and lets more daylight into the room, a real advantage in Pasadena’s bright, high-sun climate where window walls and garden-facing openings matter.

The wall thickness on the aluminum extrusion is 0.079 inches. That’s a meaningful number. It’s thick enough to resist racking and bowing during installation and over decades of thermal cycling, but not so bulky that the frame overpowers the glass. Pasadena’s older homes, Craftsman bungalows, Spanish Colonials, mid-century ranches, all benefit from a hung window that respects the original proportions of the opening. We’ve installed the VLX 500 in homes from Bungalow Heaven to the San Rafael Hills, and the feedback is consistent: it feels like a window that belongs on the house.

The tilt-in sash mechanism is the feature people mention most after living with the window for a year. A simple release lets each sash swing inward so the exterior glass surface is reachable from inside. For Pasadena homes with second-story windows or windows set above porches and retaining walls, that’s the difference between clean glass and streaked glass. It also means you’re not paying a window cleaning service twice a year.

Performance Features

Thermal Efficiency. The VLX 500 frame carries a thermal break, which separates the interior and exterior aluminum surfaces to slow heat transfer. Paired with Low-E glass, the window earns NFRC-rated energy performance numbers that matter in Pasadena, where summer afternoons regularly push into the 90s and air conditioning runs for months. Your cooling load drops when the window isn’t acting as a radiator.

Acoustic Performance. Aluminum hung windows have a reputation for being noisy, but the VLX 500’s tighter perimeter seals and laminated glass option change that math. Homes along the 210, Colorado Boulevard, or near the Rose Bowl see real sound reduction when we upgrade from older single-pane aluminum. Laminated glass is the single biggest acoustic upgrade you can spec on this window.

Airtightness & Weather Seal. Every VLX 500 we install in Pasadena gets AAMA 812 low-expansion foam sealant on all perimeter joints. That’s not a bonus step. It’s how the window achieves its airtightness rating and how we prevent the slow air leakage that shows up as dust on the sill and higher energy bills. The weatherstripping at the meeting rail and jamb is designed to compress evenly, which keeps the sashes sliding smoothly without gaps.

Waterproofing. Pasadena gets real rain, and when it comes, it comes fast. The VLX 500’s sill design directs water outward and away from the interior, and the AAMA 812 perimeter seal prevents moisture from wicking behind the frame. Drainage channels in the sill track let water escape even during wind-driven rain. Properly installed, this window does not leak, and we stand behind that.

Wind Resistance. Pasadena sits where it sits: below the San Gabriels, catching canyon winds in certain neighborhoods and Santa Ana gusts in the fall. The VLX 500’s wind-load rating is engineered for exactly this geography. The 0.079-inch wall thickness and reinforced corner construction keep the frame square under pressure, so the sash doesn’t rattle or bind when the wind picks up.

Security & Hardware. The VLX 500’s locking mechanism is a positive-engagement lock, not a friction catch. It seats the sash firmly against the frame and resists prying. For homeowners who want an extra layer, impact-resistant laminated glass holds together if struck, which slows forced entry and protects the interior. That’s a popular spec on Pasadena homes with large ground-floor windows facing the street.

Color & Glass Options

The VLX 500 comes in six finishes, and each one works differently depending on the architecture. Premium Black is the current go-to for Pasadena’s modern and farmhouse-style remodels; it creates a strong outline against stucco and white interiors. Pure White is the classic choice for traditional homes and rentals, clean and forgiving against any wall color. Anodized Silver has a raw aluminum look that suits mid-century and commercial-style residential work. Bronze sits between black and silver, a warmer dark tone that reads well on Spanish and Mediterranean facades. Champagne is a softer metallic with a warm cast, often specified on higher-end custom homes in the hills. Teak Wood is a wood-grain finish on aluminum, ideal when you want the look of wood windows without the maintenance, common on Pasadena Craftsman restorations where original wood windows are too far gone to save.

On the glass side, Clear is the budget-friendly standard. Frosted works for bathrooms, entries, and sidelights where privacy matters. Low-E is the energy play, reflecting heat while keeping visible light. Tempered is safety glass that shatters into small pieces instead of sharp shards, required by code in certain locations. Laminated adds both acoustic and impact benefits. Most Pasadena homeowners end up combining Low-E with either tempered or laminated depending on the room.

Installation by Lightwell Windows Pasadena in Pasadena

We install the VLX 500 the way a window should be installed: level, plumb, and square, with every perimeter joint sealed to AAMA 812 standard. The process starts with a pre-install inspection of the existing opening. We check the rough opening dimensions, look for water damage or rot in the surrounding framing, and confirm the new window will sit properly. In Pasadena’s older housing stock, rough openings are rarely square, and slapping a new window into an opening that’s out of whack can ruin the operation of even the best-built product from day one.

During install, we shim the frame precisely, shim and secure every anchor point, and verify level and plumb on both axes before the window is fastened. Then the full perimeter gets fresh AAMA 812 low-expansion foam, which seals, insulates, and deadens sound. Flashing and trim follow, and finally we run a water test on the exterior to confirm drainage paths work as designed. The crew leaves the site clean, hauling old windows, debris, and packaging.

Installation matters because ViewLux’s warranty protects the product, not a bad install. If a window is installed out of square, the sash binds. If the perimeter isn’t sealed, you get air and water intrusion. If the flashing is wrong, you get a slow leak that rots the framing over years. Hiring Lightwell Windows Pasadena means the product and the installation are covered by one accountable local company. We serve all of Pasadena, plus Altadena, South Pasadena, San Marino, Arcadia, and Sierra Madre. Call (626) 628-2308 to schedule a free on-site measurement.

Frequently Asked Questions – VLX 500 Single & Double Hung Window

What is the lead time for the VLX 500 Single & Double Hung Window? Most VLX 500 orders arrive at our Pasadena shop within 4 to 6 weeks of final measurements and finish confirmation. Custom colors and laminated glass can push that to 8 weeks. We’ll give you a firm timeline when we quote, not a guess.

Does the VLX 500 qualify for energy tax credits? The VLX 500 with Low-E glass qualifies for available federal and utility energy incentives when it meets the current ENERGY STAR criteria, and many Pasadena homeowners take advantage of these programs. We’ll give you the spec sheet to confirm eligibility with your tax professional before you order.

What warranty comes with the Single & Double Hung Window? ViewLux provides a manufacturer’s warranty on the VLX 500 against defects in materials and workmanship, and Lightwell Windows Pasadena covers our installation labor. We’ll walk you through the exact terms before you sign anything, in plain English, with no buried fine print.

Can I customize the size? Yes, the VLX 500 is made to order to your specific rough opening dimensions, not sold in fixed stock sizes. We measure every opening on site in Pasadena and order each window to fit precisely, which means fewer gaps to seal and cleaner sightlines.

How do I maintain aluminum frames? Wash the frames twice a year with mild soap and water, keep the tracks free of debris, and lubricate the sash mechanism annually with a dry silicone spray. The baked-on finish doesn’t need painting or sealing, which is a major advantage over wood windows in Pasadena’s sun and dry heat.

How much does the VLX 500 cost in Pasadena? Pricing depends on size, glass package, finish, and whether it’s single or double hung, but most standard Pasadena openings land in the $850 to $1,700 range per window installed.
