Product Overview – VLX 100 Double Swing / French Door

The VLX 100 Double Swing is what happens when aluminum engineering meets the classic French door format. Paired aluminum French doors with symmetrical sightlines, flush threshold, and multi-point lock hardware. The two panels swing from opposite jambs and meet in the middle, giving you the full-width opening that sliders and single doors simply can’t match. When both leaves are open, you get roughly 8 feet of clear passage, which changes how a room connects to a deck, patio, or garden.

Why aluminum over wood or vinyl? Because San Francisco is hard on materials. Fog, salt air near the Outer Sunset and Richmond, seasonal rain, and temperature swings that cause wood to swell and vinyl to flex. Aluminum stays dimensionally stable through all of it. The VLX 100 uses a thermal break, a non-conductive barrier between the interior and exterior aluminum profiles, which prevents condensation and heat transfer through the frame. That’s the feature that separates modern aluminum doors from the cold, drafty aluminum of the 1970s.

The design fits homes where the door is meant to be seen, not hidden. Homeowners choose this series for dining rooms that open to a backyard, living rooms stepping out to a roof deck in Potrero Hill, or a primary suite with a Juliet balcony in Russian Hill. The profile is substantial enough to feel solid when it closes, but narrow enough to keep sightlines open. This is a door you buy once.

Technical Specifications

Here’s what the VLX 100 Double Swing actually brings to the table. These are manufacturer engineering specs, not marketing numbers:

• Wall thickness: 0.098 inches, the aluminum extrusion gauge. Thicker than typical residential-grade profiles, which is why these doors don’t flex or rattle in wind.
• Profile width: 2.56 inches. Slim enough for modern sightlines, wide enough to house the thermal break and multi-point lock mechanism without compromise.
• Maximum span: Up to 96 inches wide when configured as a double swing. That’s the total rough opening width for paired panels.
• Glass options: Clear, Frosted, Obscure, Low-E, Tempered, Laminated.
• Finish options: Premium Black, Pure White, Anodized Silver, Bronze, Champagne, Teak Wood.
• Screen options: Retractable Screen, or none for a clean, unobstructed opening.

These specs put the VLX 100 in a category with doors costing significantly more. We’re happy to show you the physical door sample in person at your home so you can see the profile depth and finish quality before committing.

Performance Features

Thermal Efficiency – The thermal break inside the frame interrupts the conductive path between exterior and interior aluminum. Combined with Low-E glass, the VLX 100 gets the NFRC energy ratings that matter when you’re heating a Pacific Heights flat or cooling a Mission loft with afternoon sun exposure.

Acoustic Performance – If you live near the N-Judah tracks, a Muni bus route, or just a loud street in the Richmond, you’ll feel the difference a well-sealed aluminum door makes. The VLX 100’s sound control ratings are materially better than an old wood or vinyl door with perimeter gaps.

Airtightness & Weather Seal – When we install the VLX 100 in San Francisco, we seal every perimeter joint with AAMA 812 low-expansion foam. That’s the standard that prevents the micro-gaps that cause drafts most homeowners never find. The result is a door frame that holds air inside and keeps fog moisture outside.

Waterproofing – San Francisco gets an average of 25 inches of rain a year, mostly arriving sideways. The VLX 100 uses a sill design that channels water down and out, never in. After every installation, our crew runs a water test before we clean up and call it done.

Wind Resistance – Wind-load ratings matter when you’re on an elevated deck in Noe Valley or a hillside home in Twin Peaks where gusts funnel through. The 0.098-inch wall thickness gives the VLX 100 the structural weight to hold its shape and its seal in high-wind conditions.

Security & Hardware – The multi-point lock hardware engages at multiple points along the frame when you lift the handle. That’s not a single deadbolt, it’s a full-length lock system, and it’s a reason these doors are popular for ground-floor units in the Marina and North Beach.

Color & Glass Options

The VLX 100 Double Swing comes in six finish options. Premium Black is the most popular in San Francisco right now, especially on modern and contemporary homes where dark frame contrast is the point. Pure White suits traditional Victorians and shingled houses. Anodized Silver reads industrial and pairs well with steel or concrete; Bronze gives warmth without heaviness. Champagne is the least expected and sometimes the best choice for a home that doesn’t fit a mold. Teak Wood is a wood-grain finish that gives you the look of timber with aluminum’s weather resistance, which works on Bay Area bungalows and craftsman-era homes.

On glass, Clear is the default for unobstructed views. Frosted and Obscure are for bathrooms, ground-floor bedrooms, or any door facing a busy street in the Castro or Hayes Valley. Low-E is the one you want for energy efficiency, it blocks solar heat while keeping light. Tempered is safety glass and required by code for doors; Laminated adds a layer of impact resistance and sound dampening. If you’re in a noisy corridor or have kids who treat doors as a contact sport, laminated glass is worth the upgrade.

Installation by Lightwell Windows San Francisco in San Francisco

A door is only as good as its installation. The VLX 100 can be perfect out of the factory and fail within two years if the installer cuts corners. That’s the honest truth of this industry. We install every VLX 100 Double Swing door in San Francisco to AAMA 2400/2410 standards, which means the opening is measured precisely, the frame is set level, plumb, and square, and the anchoring is engineered for the specific wall construction.

Our process starts with a pre-install inspection. We look at the existing opening, the wall condition, the waterproofing situation, and the access path for the new door. On older San Francisco homes, we frequently find dry rot or settling that has to be addressed before the new door goes in. We flag it, quote it, and fix it. Then we set the frame. A level frame is what keeps the panels from sagging or binding years later. Every perimeter joint gets sealed with AAMA 812 low-expansion foam, which is the same standard commercial glaziers use because it doesn’t warp the frame and it holds its seal.

After the door is in, we water test, we check the multi-point lock engagement at every point, and we walk the door with you before we leave. We also register your installation with the manufacturer so the warranty documentation is clean if anything ever goes wrong. Improper installation voids the manufacturer warranty. That’s the risk with handyman installs, and it’s the main reason San Francisco homeowners call us instead. Call (831) 480-4124 to schedule an on-site measurement.

Frequently Asked Questions – VLX 100 Double Swing / French Door

What is the lead time for the VLX 100 Double Swing / French Door? The VLX 100 is a custom-built door, not an off-the-shelf product, so lead time typically ranges from 6 to 10 weeks depending on finish, glass, and the current manufacturer production queue. We’ll give you a clear timeline when we quote the project. Call (831) 480-4124 and we can check current lead times for your specific configuration.

Does the VLX 100 qualify for energy tax credits? It depends on the glass package and the federal or California credits in effect for the tax year of installation. Low-E glazing on a thermally broken frame is generally the configuration that meets or exceeds the performance thresholds for efficiency incentive programs. Ask us during the consultation and we’ll point you to the right documentation for your situation.

What warranty comes with the Double Swing / French Door? The manufacturer’s warranty covers the door components and the installation warranty from Lightwell Windows San Francisco covers our workmanship. Exact terms depend on the year and configuration, but you’ll get written warranty documentation at installation. The key is professional installation, because a door installed outside spec won’t be covered no matter what the paperwork says.

Can I customize the size? Yes, within the structural limits of the system. The VLX 100 Double Swing can span up to 96 inches wide in a paired configuration. Door height, panel width split, and swing direction (inward or outward) are all configurable to your opening and how you use the space.

How do I maintain aluminum frames? Wipe the frames down with mild soap and water twice a year, especially if you’re near the ocean where salt deposits build up. Lubricate the hinges and lock mechanism annually with a silicone-based lubricant. The aluminum itself doesn’t rot, warp, or need refinishing, but the hardware performs better with basic attention. If you ever notice a seal wearing, call (831) 480-4124 and we’ll send a tech out before it becomes a bigger issue.
