The VLX 80 Casement Window is a side-hinged aluminum window built around two ideas: ultra-narrow sightlines and maximum ventilation. For San Francisco homeowners, that combination matters. Victorian bay windows want glass, not frame. Fog-season homes want as much airflow as possible when the marine layer burns off. Lightwell Windows San Francisco is an authorized ViewLux installation partner, which means we sell, measure, and install this product directly, and we stand behind the install with the same care ViewLux puts into manufacturing.

Product Overview – VLX 80 Casement Window
Casement windows have one job they do better than any other style: they open fully. A double-hung gives you half the opening. A slider gives you half. The VLX 80 opens the entire sash outward on side hinges, catching San Francisco’s afternoon breeze and pulling it through the room. That’s the ventilation story.
The sightline story is just as important. The VLX 80 uses a slim aluminum profile measuring 1.97 inches wide. On a Victorian in Noe Valley or a mid-century in Diamond Heights, that thin frame disappears into the wall, leaving more visible glass and less metal. The wall thickness of the aluminum extrusion is 0.079 inches, which gives the frame real structural weight without looking bulky. Homeowners choose this series when they want a modern look that won’t fight the house it’s going into.
Aluminum is the right material for San Francisco for another reason: salt air. Homes in the Sunset, the Richmond, and anywhere west of Twin Peaks live in a marine environment that corrodes lesser materials. Aluminum with a quality finish resists that. We’ve installed VLX 80 windows within sight of Ocean Beach, and the frames hold up the way wood and vinyl don’t. ViewLux designs the VLX 80 for exactly these conditions, and as an authorized partner, we’re the ones who make sure it’s installed to spec.

Technical Specifications
Here are the hard numbers on the VLX 80 Casement Window, reworded from the spec sheet so they’re easy to act on:
- Frame material: Extruded aluminum with a wall thickness of 0.079 inches, built for coastal exposure.
- Profile width: 1.97 inches, one of the narrowest frames in the ViewLux aluminum line.
- Operation: Side-hinged casement, single sash, opens outward.
- Glass options: Clear, Frosted, Low-E, Tempered, Laminated. Laminated is the impact-resistant option for higher wind-load zones and added security.
- Finish options: Premium Black, Pure White, Anodized Silver, Bronze, Champagne, Teak Wood.
- Screen options: Fixed Screen or Retractable Screen.
- Sill options: Standard Sill or Low-Profile Sill. Low-profile is popular in modern remodels where a flush transition matters.
- Energy performance: Thermally broken frames tested to NFRC standards. The thermal break separates interior and exterior aluminum so heat stays where you want it.
- Installation standard: Installed to AAMA 2400/2410 guidelines by Lightwell Windows San Francisco.
Performance Features
Thermal Efficiency. The VLX 80 uses a thermal break inside the aluminum frame. Aluminum conducts heat easily, but the break interrupts that path, which is why this window carries NFRC-rated energy performance. In San Francisco, that means less heat loss on cold Richmond District nights and less heat gain during September heat waves in the Mission.
Acoustic Performance. Aluminum frames plus quality glazing equals real sound reduction. The VLX 80 is designed for sound control, which matters if you live near Muni lines, the 19th Avenue corridor, or any of San Francisco’s busier streets. Laminated glass adds even more acoustic damping and qualifies as impact-resistant glazing.
Airtightness & Weather Seal. Casement windows seal better than sliders by design. When the sash closes, it compresses against the frame gasket along all four sides. The VLX 80 is engineered for airtightness, which is one reason it performs well in windy exposures where sliders leak air.
Waterproofing. We install every VLX 80 with AAMA 812 low-expansion foam sealant on all perimeter joints. Combined with proper sill flashing, this is the layer that stops water intrusion during San Francisco’s sideways winter rain. The window itself is designed for water resistance, but the install seals the deal.
Wind Resistance. The VLX 80 is wind-load rated for local climate requirements. Co-ops and condos in high-rise buildings often require documentation of wind-load performance, and this product delivers it. The 0.079-inch wall thickness gives the frame the rigidity it needs under sustained coastal wind pressure.
Security & Hardware. Casement hardware locks at multiple points along the frame, not just one latch in the middle. The VLX 80’s multi-point locking system makes the sash much harder to pry open than a sliding window. Impact-resistant laminated glass is available for ground-floor units and areas where added security makes sense.

AfterColor & Glass Options
The VLX 80 comes in six finishes. Premium Black is the most common choice for modern and contemporary homes in San Francisco, especially in new construction and high-end remodels in Potrero Hill and the Design District. Pure White reads clean and bright, and it’s the safest match for traditional Victorians and Edwardians. Anodized Silver gives you a true metallic aluminum look that works beautifully on mid-century buildings and commercial storefronts. Bronze is warm and understated, a strong choice for Mediterranean-style homes in the Marina or St. Francis Wood. Champagne offers a softer metallic tone that complements warm plaster and wood interiors. Teak Wood is a wood-grain finish, the option to consider when you want the warmth of wood without the maintenance and rot risk that comes with real wood frames in a marine climate.
On the glass side, Clear is standard. Low-E is the energy-performance glass that most San Francisco buyers choose, since it reduces heat transfer without changing the view much. Frosted works well for bathrooms, entry sidelights, and any window facing a close neighbor. Tempered is safety glass required by code in certain locations. Laminated is the impact-resistant option, and it also provides the best acoustic performance of the group.
Installation by Lightwell Windows San Francisco in San Francisco
The window is only as good as the install. That’s not sales talk. A poorly installed casement window will bind when you crank it, leak at the first winter rain, and void the manufacturer warranty. We install every VLX 80 to AAMA 2400/2410 standards, which is the accepted North American installation guideline for residential windows. The warranty stays intact because the install is done right.
Our process starts with a pre-install inspection. We measure the existing rough opening, check for water damage in the surrounding framing, and evaluate the condition of the exterior weather barrier. Then we remove the old window, prep the opening, and set the new sash level, plumb, and square. A casement window that’s installed even slightly racked will not seal properly. We check with a level on every axis before securing the frame.
After setting, we seal the entire perimeter with AAMA 812 low-expansion foam sealant. This is a key step that cheap installers skip. The foam expands just enough to fill gaps without bowing the frame, then we trim and flash the exterior. We finish with a water test at every window we install, hose-testing the exterior to confirm there is no water intrusion before we call the job done. Cleanup is part of the scope, not an afterthought: we haul off the old windows, sweep the job site, and leave your home cleaner than we found it.
San Francisco building codes and HOA requirements can add complexity. Many buildings in San Francisco require matching window styles, specific glazing for energy codes, or even historical review. We’ve installed through enough of those processes to help you navigate them. Call (831) 480-4124 and we’ll walk you through what your specific building requires.
Frequently Asked Questions – VLX 80 Casement Window
Lead time for the VLX 80 Casement Window varies by size, finish, and glass selection, but most orders arrive within a few weeks from ViewLux. The best way to get an accurate date is to call (831) 480-4124 with your rough dimensions. We’ll give you a written quote and a realistic delivery window before you commit.
The VLX 80’s thermal break and NFRC-rated energy performance mean it can qualify for federal energy tax credits, but your eligibility depends on the specific glass package and your household’s tax situation. We install the right Low-E configuration for San Francisco’s climate zone. Talk to your tax professional about credit eligibility, and call us for the spec documentation you’ll need to file. Call (831) 480-4124 for exact specs on your build.
ViewLux provides a manufacturer warranty on the VLX 80 covering the frame and hardware, and the glass carries its own coverage. The key detail is that the warranty only applies when the window is installed to AAMA standards by an authorized partner. We are that partner. Call (831) 480-4124 and we’ll send you the full warranty document for your specific order.
Yes. The VLX 80 is not a stock-size product. Each window is fabricated to your measurements, which means you’re not forced to either shrink or enlarge a rough opening. Custom sizes matter in San Francisco, where many older homes have non-standard openings that big-box replacement windows can’t fit. We measure every opening precisely before ordering, and that measurement is part of our free on-site estimate. Call (831) 480-4124 to schedule yours.
Aluminum frames need very little maintenance. Wipe the aluminum down with mild soap and water a few times a year, keep the drain channels clear of debris, and lubricate the hinge and crank mechanism annually with a silicone-based lubricant. Compared to wood, which needs repainting and can rot in San Francisco’s damp climate, the VLX 80 is nearly zero-maintenance. Call (831) 480-4124 if you ever need service on hardware, and we’ll take care of it.
