Product Overview – VLX 500 Single & Double Hung Window

The VLX 500 is the window you choose when you want that classic vertical sash look without the maintenance headaches that come with wood or older aluminum frames. Both the top and bottom sash glide independently on smooth tracks, and each sash tilts inward, so you can clean the exterior glass from inside your home, no ladder or squeegie-from-the-sidewalk routine required. On a second-story San Diego bedroom that faces a canyon or the ocean, that tilt-in feature alone sells the window.

What makes this series stand out is the aluminum engineering. The frame carries a wall thickness of 0.079 inches and a profile width of 2.36 inches, which gives it a slim, architectural face but a rigid backbone. Aluminum doesn’t absorb moisture, so it won’t swell in the marine layer that rolls through Point Loma and La Jolla every morning, and it won’t soften under the inland heat that bakes Santee and El Cajon in August. Buyers choose the VLX 500 over vinyl because it holds its shape for decades, and over wood because it never needs repainting or re-caulking season after season.

Architecturally, it works everywhere. Single hung suits smaller openings, bathrooms, and utility rooms where you only need the bottom sash to move. Double hung fits living rooms, kitchens, and bedrooms where you want airflow from both the top and bottom, pulling hot air out while drawing cooler air in, which matters when you’re trying to keep a Chula Vista craftsman comfortable without running the AC all afternoon.

Technical Specifications

Performance Features

Thermal Efficiency: The VLX 500 uses a thermal break inside the frame, which physically separates the interior and exterior aluminum so heat doesn’t transfer straight through the metal. NFRC-rated energy performance means you can compare this window’s U-factor and SHGC against any other window on the market before you buy. In San Diego’s climate, Low-E glass paired with this frame keeps afternoon sun from cooking west-facing rooms in Mission Hills and University Heights.

Acoustic Performance: Aluminum frames with a thermal break also dampen sound transmission. If you live near the 5, the 8, or the trolley line through Mission Valley, the VLX 500 with laminated glass cuts down traffic noise noticeably. We’ve installed these in homes along Washington Street in Hillcrest where the difference was immediate.

Airtightness & Weather Seal: The sash locks against the frame with designed compression, not just a flimsy felt strip. Every perimeter joint gets AAMA 812 low-expansion foam sealant during installation, which closes the micro-gaps where drafts sneak in. The result is fewer dust lines on the sill and a steadier indoor temperature.

Waterproofing: Aluminum doesn’t rot, and the VLX 500’s weep system channels any incidental moisture out through the bottom of the frame instead of letting it pool. Proper installation adds a second layer of protection: our crew seals the full perimeter per AAMA 812 and follows AAMA 2400/2410 standards so water can’t migrate behind the frame into the wall cavity.

Wind Resistance: The 0.079″ wall thickness gives these frames serious stiffness. The VLX 500 is wind-load rated for local climate requirements, which covers everything from coastal gusts in Ocean Beach to the Santa Ana winds that punch through the canyons east of downtown San Diego each fall.

Security & Hardware: Tilting sashes lock into a positive engagement cam system, and the laminated glass option adds a film layer that holds glass together even if struck. That’s the option we suggest for ground-floor San Diego windows facing alleys or street access.

Color & Glass Options

The VLX 500 comes in six finishes. Premium Black is the dominant choice for modern farmhouse and contemporary builds popping up in North Park and South Park right now: sharp contrast against white stucco. Pure White stays classic for Spanish revival homes, pairing well with terracotta and tile. Anodized Silver gives you that raw, machined metal look and works beautifully on mid-century homes in Clairemont and Del Cerro. Bronze and Champagne are the softer metal tones, excellent for Mediterranean style houses in Point Loma that want warmth without going dark. Teak Wood is a wood-grain finish on an aluminum frame, so you get the look of stained teak with zero maintenance.

Glass selection depends on the room. Clear is standard and economical. Frosted makes sense in bathrooms where privacy matters but natural light still needs to get through. Low-E is our default suggestion for any sun-facing window in San Diego, since it reflects infrared heat while keeping the view clear. Tempered is safety glass that shatters into small pebbles instead of large shards. Laminated is the impact-resistant choice, recommended for ground-level security or windows facing high-wind exposures.

Installation by Westlight Windows San Diego in San Diego

Windows fail for two reasons: bad manufacturing or bad installation. The VLX 500 is a well-engineered window, which means the install is what determines whether you’ll be happy with it in 15 years. We treat installation as the product. Here’s how we handle every VLX 500 install in San Diego.

First, we inspect the existing opening and framing before we quote. Hidden rot, out-of-square openings, or old water damage changes the scope, and you should know that before work starts. Once the old window comes out, we set the new frame level, plumb, and square in the opening using shims, and we check it with a laser. If a frame goes in twisted, the sashes will never glide properly, and no amount of adjustment fixes it later.

We seal every perimeter joint with AAMA 812 low-expansion foam sealant, which not only insulates but prevents air and water from moving behind the frame. The entire installation follows AAMA 2400/2410 standards. Then we run a water test on the exterior seal, install the trim, and clean the site completely. You get a walkthrough when we’re done, not a pile of debris and a “call us if anything looks off.”

Why does this matter in San Diego? Our climate is mild, but we get hard rain when it comes, and coastal homes see constant salt air. A poorly flashed window in Point Loma leaks within a year or two. An unsealed opening in La Mesa lets ants and drafts in. And here’s the part most homeowners miss: if your installer doesn’t follow the manufacturer’s installation guidelines, the warranty is void. You paid for that coverage. Our installation keeps it alive.

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 San Diego facility in about 3 to 4 weeks, depending on the glass and finish you choose. Custom sizes and laminated glass can add a week. Call (619) 793-3829 and we’ll give you a current lead time for your specific configuration.

Does the VLX 500 qualify for energy tax credits? In many cases, yes. The VLX 500 with Low-E glass and thermal break technology meets the ENERGY STAR criteria for the Southern California climate zone, which is the baseline for most efficiency incentives. We can tell you during your quote which glass package you need to qualify.

What warranty comes with the VLX 500 Single & Double Hung Window? The VLX 500 carries a manufacturer warranty that covers the frame, sashes, and hardware, and the glass carries its own separate coverage. The key detail: the warranty only stands if the window was installed per the manufacturer’s spec, which is the standard Westlight Windows San Diego builds every install around.

Can I customize the size? Absolutely. Single and double hung windows are built to the opening, not sold in fixed increment sizes only. We measure every opening in San Diego to the exact dimension and order the VLX 500 to fit. Odd sizes are not a problem.

How do I maintain aluminum frames? Wipe the frames and tracks twice a year with warm water and a mild soap, and clear the weep holes at the bottom with a soft brush. Lubricate the track rollers or sash guides with a silicone-based spray if you feel resistance. The finish never needs painting or sealing. That’s the whole maintenance routine.
