Product Overview – VLX 80 Awning Window

The VLX 80 solves a problem almost every San Francisco homeowner knows: you want ventilation, but fog, drizzle, and marine-layer mornings make horizontal sliders and double-hungs a gamble. Because this window hinges at the top and opens outward at the bottom, the sash acts like a small awning over the opening. Rain hits the glass and runs off, not into your house. That one design decision changes how you use the room. You can leave the window cracked open overnight in the Richmond District, the Sunset, or Noe Valley without waking up to a wet sill.

ViewLux builds the VLX 80 around an aluminum frame with a thermal break, which is the engineering detail that separates modern aluminum windows from the cold, condensation-prone frames people remember from older San Francisco apartment buildings. The break interrupts the metal’s natural tendency to transfer heat and cold, so the inside face of the frame stays closer to room temperature. That matters in a city where summer days swing from 55 degrees at 7 a.m. to 75 by 2 p.m., and where winter nights hover in the 40s for months at a time.

Architecturally, the VLX 80 fits both the flat-front Edwardian and Victorian homes that define so many San Francisco neighborhoods and the newer steel-and-glass infill projects going up in the Mission and Dogpatch. The frame profile is slim enough to read as contemporary, but the awning operation feels classic and unpretentious. Buyers choose this series when they want a window that performs first and styles second, without paying custom-millwork prices for the privilege.

Meridian Windows and Doors San Francisco stocks and installs the VLX 80 across the city, from Bernal Heights up to the Presidio. Our crews have set these windows in softwood framing from the 1920s, in post-war stucco boxes, and in brand-new shear-wall construction. The window itself is consistent. The installation is where the outcome gets decided, and that’s the part we control.

Technical Specifications

Here’s the VLX 80 Awning Window by the numbers, reframed the way we explain it to homeowners during a site visit in San Francisco:

• Frame wall thickness: 0.079 inches of extruded aluminum, which gives the sash rigidity without adding visual bulk.
• Profile width: 1.97 inches overall frame depth, a middle-ground dimension that works in both new construction and retrofit openings.
• Glass options: Clear, Frosted, Low-E, Tempered, and Laminated, each available in a range of thicknesses depending on the rough opening size and wind-load requirements for your specific San Francisco elevation.
• Finishes: Premium Black, Pure White, Anodized Silver, Bronze, Champagne, and Teak Wood.
• Screen options: Fixed Screen or Retractable Screen, both mounted on the interior side of the opening so the awning operation stays unobstructed.
• Operation: Top-hinged, outward-opening sash driven by a smooth crank mechanism, with multi-point locking hardware at the sill.
• Installation standard: Set, shimmed, and sealed per AAMA 2400/2410, with AAMA 812 low-expansion foam at every perimeter joint.

Performance Features

Thermal Efficiency. The built-in thermal break separates the exterior and interior aluminum faces, which cuts heat transfer through the frame by a meaningful margin compared to non-thermal aluminum. When paired with Low-E glass, the VLX 80 carries NFRC-rated performance that holds up in San Francisco’s coastal Zones 3 and 4, where the concern is usually heat loss, not heat gain.

Acoustic Performance. San Francisco is a loud city. Buses on Geary, Muni lines on Judah, garbage trucks at 6 a.m. in the avenues. The VLX 80’s multi-point locking hardware compresses the sash into the weather seal, reducing air gaps, and the acoustics improve further with Laminated glass. For homes near commercial corridors or school zones, Laminated is the spec we recommend most often.

Airtightness & Weather Seal. The sash closes against a continuous compression gasket that runs the full perimeter of the frame. No gaps, no whistling on windy afternoons, no fog-line smell seeping into a Pacific Heights living room in August. The AAMA 2400/2410 installation discipline we follow ensures the frame-to-wall connection is just as tight as the frame-to-sash connection.

Waterproofing. The awning geometry does the first layer of water-shedding work. The perimeter seal does the second. We finish every installation with AAMA 812 low-expansion foam around the entire frame, followed by an exterior-grade sealant joint that moves with the building. In a city where fog and drizzle are a feature eight months of the year, this is the detail that keeps paint from bubbling and sills from staining.

Wind Resistance. San Francisco hills create wind corridors that catch flat-front windows hard, especially on west-facing exposures in the Outer Sunset and along Twin Peaks. The VLX 80’s aluminum extrusion, at 0.079 inches wall thickness, holds its shape under wind load better than vinyl or thin-gauge aluminum competitors. The window is wind-load rated for local climate requirements, and we verify the right glass package and frame size for your specific exposure during the free site visit.

Security & Hardware. Awning windows are already harder to force open than sliders because the locking point is at the sill, away from casual reach. The VLX 80 adds multi-point hardware that engages at two or more positions along the bottom rail. Add Tempered or Laminated glass and you have a window that resists both intrusion and accidental impact, which matters for ground-floor units in the Mission and Bayview.

Color & Glass Options

The VLX 80 comes in six finishes, and they break down roughly along architectural lines in San Francisco. Pure White and Premium Black dominate the modern and contemporary projects going up in Mission Bay, the Dogpatch, and along the Embarcadero. Anodized Silver and Bronze suit the mid-century apartment buildings and commercial-to-residential conversions scattered through SoMa and Russian Hill. Champagne is a warmer metallic that reads well in traditional condos where the hardware is brass or oil-rubbed bronze. Teak Wood is the choice for homeowners in the Marina, Pacific Heights, and Noe Valley who want the warmth of a wood window without the maintenance calendar that real wood demands in a fog-and-salt-air environment.

On the glass side: Clear is the budget baseline. Frosted works for bathrooms and any window facing a neighboring wall or a busy street, where you want light without the view. Low-E is the energy upgrade we almost always recommend in San Francisco, because it pays for itself faster here than anywhere else in California. Tempered meets code for windows near doors and those set low in walls, and Laminated handles both security and the acoustic needs of loud neighborhoods. Most San Francisco projects mix glass types by room rather than using one spec throughout, and we’ll help you decide which combination makes sense for your own window schedule.

Installation by Meridian Windows and Doors San Francisco in San Francisco

Installing an awning window in San Francisco is not the same job as installing one in a new subdivision in the East Bay. Our city is full of old growth redwood frames that have shifted over a century, stucco walls that hide water damage until the old window comes out, and lot lines so tight that the window you’re replacing may be 14 inches from your neighbor’s wall. Good installation starts with the site inspection, where we check the rough opening for size, square, and hidden rot before any material gets ordered or any work gets scheduled.

On install day, our crew sets the frame level, plumb, and square, and we shim it in place rather than relying on the rough opening to hold it true. A window that’s racked even three-sixteenths of an inch will bind at the crank, wear its hardware early, and never seal the way the NFRC rating assumes. We then insulate the perimeter with AAMA 812 low-expansion foam, which fills the micro-gaps between frame and wall without bowing the frame. The exterior joint gets a sealant that meets AAMA 2400/2410 standards for joint design and material selection. We finish with a water test and a walkthrough so you can see how the crank, the lock, and the window itself perform before we pack up.

One thing we’re blunt about: an improperly installed window voids the manufacturer warranty. Not partially. Fully. The frame may be perfectly square, the glass perfect, the hardware perfectly machined. If water gets behind the frame because the perimeter wasn’t sealed or the sill wasn’t flashed, the warranty claim dies on the table. Hiring Meridian Windows and Doors San Francisco means the installation carries the same standard as the product. We are an authorized ViewLux partner, and we’re accountable to both the manufacturer and to you.
