VLX 80 Casement Window

VLX 80 Casement Window in San Francisco, CA | Meridian Windows and Doors San Francisco

The VLX 80 Casement Window is a side-hinged aluminum window built around two things San Francisco homeowners ask about most: maximum glass and maximum airflow. The 1.97-inch frame profile disappears into the opening, so you get noticeably more daylight than a traditional casement, and because the sash swings fully outward on side hinges, it catches the bay breeze better than any sliding or fixed window ever will. Meridian Windows and Doors San Francisco is an authorized ViewLux installation partner, which means you’re getting the product direct from a factory-trained local team that measures, installs, and stands behind it.

Product Overview – VLX 80 Casement Window

The VLX 80 was engineered for the kind of architecture you see all over San Francisco, from Marina District stucco flats to mid-century homes in the Sunset and new builds in Noe Valley. What sets it apart is the balance between structural rigidity and visual lightness. The frame is aluminum, which means it won’t warp, swell, or sag the way wood and vinyl do in our fog-and-salt-air climate. But the profile width is only 1.97 inches, so the window reads as glass with a thin metal border rather than a heavy frame breaking up the view.

Casement windows in general outperform sliders and double-hungs on ventilation because the entire sash opens outward like a door, channeling wind directly into the room. The VLX 80 maximizes that effect with a wide opening angle and no center rail blocking the opening. For San Francisco buyers replacing drafty single-pane windows from the 1960s or 1970s, the difference in both comfort and energy cost is immediate. And since Meridian Windows and Doors San Francisco installs this product throughout the Bay Area, we’ve seen how it handles everything from Twin Peaks wind exposure to the salty air off Ocean Beach.

This is a window for homeowners who want a modern, minimal aesthetic without giving up performance. The engineering priorities are tight seals, thermal isolation, and hardware that stays smooth after thousands of open-and-close cycles. The frame wall thickness is 0.079 inches, which is substantial for residential aluminum and gives the sash the stiffness it needs to maintain a consistent seal against the weatherstripping. When we install one in a San Francisco home, we set it dead level and plumb so that seal stays uniform across all four sides.

Technical Specifications

Here’s the full spec breakdown for the VLX 80 Casement Window, with everything in plain terms so you know exactly what you’re getting when you order through Meridian Windows and Doors San Francisco:

• Frame material: Extruded aluminum, wall thickness 0.079 inches
• Profile width: 1.97 inches (ultra-narrow sightline design)
• Operation: Side-hinged casement, opens outward
• Glass options: Clear, Frosted, Low-E, Tempered, Laminated
• Finish options: Premium Black, Pure White, Anodized Silver, Bronze, Champagne, Teak Wood
• Screen options: Fixed Screen, Retractable Screen
• Sill options: Standard Sill, Low-Profile Sill
• Thermal performance: Thermal break technology, NFRC-rated
• Installation standard: AAMA 2400/2410 compliant, AAMA 812 sealant on all perimeter joints
• Additional ratings: Airtightness, waterproofing, mist prevention, sound control, wind-load rated

The Low-Profile Sill is worth calling out for San Francisco remodels. If you’re replacing an older window and want to preserve sightlines or meet accessibility requirements, the low-profile sill keeps the interior transition minimal without sacrificing drainage. The retractable screen is another popular pick here because it disappears entirely when you’re not using it, keeping that clean casement look intact.

Performance Features

Thermal Efficiency. The VLX 80 uses a thermal break built into the aluminum frame, which separates the interior and exterior metal so heat doesn’t conduct straight through. The result is an NFRC-rated window that holds indoor temperatures far better than non-thermal aluminum, a real consideration in San Francisco where foggy mornings turn into warm afternoons. Pair it with Low-E glass and you’ll feel the difference in both comfort and your PG&E bill.

Acoustic Performance. Aluminum is dense, and density blocks sound. The VLX 80’s multi-point locking system pulls the sash tightly against the frame gaskets, which reduces air leaks that carry noise. For homes near busy corridors like Geary Boulevard, Van Ness, or the 101, upgrading the glass to laminated adds another layer of sound reduction that makes a noticeable difference at night.

Airtightness & Weather Seal. San Francisco wind doesn’t announce itself; it just shows up. The VLX 80 is engineered with continuous perimeter gaskets and a compression locking mechanism that seats the sash firmly against the weatherstripping every time you close it. That’s what stops the drafts, the dust, and the fog-damp air from working their way in around the edges.

Waterproofing. A casement window’s weakest point in our climate is the bottom corner where wind-driven rain hits. The VLX 80’s sill is designed with internal drainage channels that direct water out and away from the interior, and when Meridian Windows and Doors San Francisco installs it, we seal every perimeter joint with AAMA 812 low-expansion foam. That’s the step most installation crews skip and the step that prevents leaks five years down the road.

Wind Resistance. The 0.079-inch frame wall and the multi-point locking hardware give the VLX 80 serious wind-load capacity. For San Francisco properties on exposed hillsides or upper floors in the Richmond and Sunset districts, where wind gusts off the Pacific hit hard, this window holds its seal and stays rigid. It’s wind-load rated for local climate requirements, not just a generic national standard.

Security & Hardware. Casement windows are inherently hard to force open because the sash presses flush against the frame and locks at multiple points around the perimeter. The VLX 80 uses stainless steel hardware that won’t corrode in our salt air, and if you want an extra layer of protection, the impact-resistant laminated glass option gives you shatter resistance that also helps with sound.

Color & Glass Options

The VLX 80 comes in six finish options, and we see distinct preferences depending on the San Francisco neighborhood. Premium Black and Anodized Silver dominate in modern builds and industrial loft conversions in SoMa and Mission Bay. Pure White remains the go-to for classic Victorians in Noe Valley and Cole Valley, where it blends with existing trim. Bronze and Champagne land somewhere in between, warm enough for traditional exteriors but refined enough for contemporary remodels in Pacific Heights. Teak Wood is a powder-coated wood-look finish that gives the look of timber without the maintenance, and it’s grown popular among homeowners in the Marina and Cow Hollow who want warmth at the frame without giving up aluminum’s durability.

On the glass side, Clear is the baseline. Frosted works well for bathrooms, side yards, or anywhere privacy matters without blocking light. Low-E is our default recommendation for San Francisco; it cuts heat gain on sunny afternoons and reduces heat loss on foggy nights. Tempered is safety glass that shatters into small pieces instead of large shards, required by code in certain locations like doors and windows near the floor. Laminated adds impact resistance and sound dampening, and it’s the option we suggest for street-facing windows on busy San Francisco blocks.

Installation by Meridian Windows and Doors San Francisco in San Francisco

Here’s the uncomfortable truth about window performance: a great window installed badly will leak, bind, and fail. The manufacturer’s warranty on the VLX 80 assumes the unit was installed correctly. If it wasn’t, the warranty doesn’t cover the resulting damage, and the problems usually show up years after the installer is gone. That’s why installation quality matters as much as the product itself, and why we don’t cut corners on ours.

Every VLX 80 installation by Meridian Windows and Doors San Francisco starts with a pre-install inspection of the rough opening. We check the framing for rot, especially in older San Francisco homes where decades of fog exposure have taken a toll on the wood around window openings. Any damaged framing gets addressed before the window goes in, because sealing a new window into bad framing just moves the problem inside the wall.

During the install, we set the window level, plumb, and square, and we shim it precisely so the sash operates smoothly and seals evenly. Every perimeter joint gets AAMA 812 low-expansion foam sealant, which creates an airtight, waterproof barrier without distorting the frame. The entire installation follows AAMA 2400/2410 standards, the industry benchmark for window installation quality. After the window is secured and sealed, we run a final water test to confirm the sill drains properly, then clean up the site completely. When we leave, the only evidence we were there is a window that opens like it should and closes like it should, every time.

Frequently Asked Questions – VLX 80 Casement Window

What is the lead time for the VLX 80 Casement Window? Most VLX 80 orders arrive in 3 to 5 weeks from the time we confirm measurements and finishes, though custom sizes or specific glass types can extend that. Call (831) 273-7126 and we’ll give you a current lead time for your exact configuration.

Does the VLX 80 qualify for energy tax credits? Yes, the VLX 80 with Low-E glass generally meets the requirements for the federal energy-efficient home improvement credit because of its NFRC-rated thermal performance. The credit amount and eligibility criteria change periodically, so we recommend confirming with your tax professional, and we can provide the NFRC ratings for your specific glass selection.

What warranty comes with the Casement Window? The VLX 80 carries a manufacturer’s warranty through ViewLux, and the coverage is only valid when the unit is installed by an authorized partner like Meridian Windows and Doors San Francisco. We’ll walk you through the specific terms at your quote appointment so you know exactly what’s covered and for how long.

Can I customize the size? Yes. The VLX 80 is built to order, so we measure your existing openings and spec the window to your exact dimensions. Standard and custom sizes are both available, and during your free on-site measurement we’ll confirm what works for your rough openings and San Francisco building code requirements.

How do I maintain aluminum frames? Wipe the frames down twice a year with mild soap and water, and keep the drainage channels at the bottom of the sill clear of debris. San Francisco’s salt air makes regular cleaning more important here than inland. The powder-coated finishes don’t need painting or sealing, and the stainless steel hardware holds up well in coastal conditions with just light lubricant on the hinges once a year. Call (831) 273-7126 if you ever have a maintenance question, and we’ll point you in the right direction.
