VLX 100 Double Swing / French Door

VLX 100 Double Swing / French Door in San Jose, CA | Westlight Windows San Jose

The VLX 100 Double Swing door is a paired aluminum French door system built around one idea: both panels should open wide when you want them to, and disappear into the wall when you don’t. San Jose homeowners choose it for kitchens that spill onto patios, living rooms that open to backyard decks, and dining rooms that need to breathe during the long warm season. Westlight Windows San Jose is an authorized ViewLux installation partner, which means we handle the product, the install, and the warranty as one accountable team.

Product Overview – VLX 100 Double Swing / French Door

The VLX 100 is engineered for paired openings where symmetry matters. Two door panels meet at the center with matching sightlines: the top rail, bottom rail, and stiles are the same width on both sides, so the closed door reads as one clean grid instead of two mismatched halves. That matters more than most people expect. A French door with uneven sightlines draws the eye to the seam. This one doesn’t.

Aluminum is the load-bearing material here, and it’s the right call for San Jose. Our dry summers and cool, occasionally wet winters punish wood doors with swelling, sticking, and rot at the threshold. Aluminum doesn’t move the same way. The VLX 100 uses a thermal break between the interior and exterior aluminum faces, so the frame stays rigid without turning your doorway into a heat sink. The flush threshold is another practical detail worth noticing: there’s no raised sill to trip over, which makes the door easier for a rolling cart, a stroller, or a grandparent who doesn’t lift their feet like they used to. Multi-point lock hardware ties the active panel into the frame at three points instead of one deadbolt, and the hardware is concealed in the profile rather than bolted onto the face.

Westlight Windows San Jose has installed this door system across Santa Clara County, from Willow Glen bungalows to Almaden Valley rebuilds. It fits equally well in a mid-century ranch that wants more glass and a newer Craftsman-style home that wants the look of traditional French doors with none of the wood maintenance.

Technical Specifications

Here are the numbers that define this door, written out plainly. The wall thickness of the aluminum extrusion is 0.098 inches, which is on the heavier end of what’s offered in residential aluminum door systems and contributes directly to the door’s stiffness and resistance to racking over time. Profile width is 2.56 inches, slim enough to keep the glass area dominant but wide enough to house the thermal break and multi-point hardware. Maximum span per opening is up to 96 inches wide, which covers most double-door rough openings in San Jose homes without requiring a custom structural header rework.

Performance Features

Thermal Efficiency – The VLX 100 uses a structural thermal break that separates the exterior aluminum from the interior aluminum, cutting conductive heat transfer through the frame. With Low-E glass specified, the assembled unit carries NFRC-rated energy performance numbers you can compare against any other door system on the market. In San Jose’s climate zone, this is the difference between a door that’s comfortable to stand next to in August and one that radiates heat into the room.

Acoustic Performance – Laminated glass is the option that changes the acoustic equation. The interlayer between the two glass panes dampens sound transmission, which matters if your French door faces a busy street in the Rose Garden neighborhood or an elementary school drop-off lane. We’ve had customers report a noticeable drop in road noise after swapping a hollow-core or single-pane door for a VLX 100 with laminated glazing.

Airtightness & Weather Seal – Every perimeter joint on the VLX 100 installation gets AAMA 812-rated low-expansion foam sealant. That’s not a nice-to-have; it’s the standard Westlight Windows San Jose follows on every install we do in San Jose. The door’s compression gaskets are designed to seal tighter as wind pressure increases, so the system doesn’t leak air on gusty winter days.

Waterproofing – The flush threshold is engineered with internal drainage channels that direct any water that gets past the weather gasket back outside rather than into your floor. Combined with a properly sloped sill pan and the AAMA 812 perimeter seal, this door is built to keep water out of a San Jose living room even during an atmospheric river event.

Wind Resistance – San Jose sits in a wind zone that demands real engineering from exterior doors. The VLX 100 is wind-load rated for the requirements in our local climate, and the wall thickness of the extrusion means the frame won’t deflect or bow under sustained pressure the way thinner aluminum profiles can. If you’re on an exposed hillside in the East Foothills, specify laminated glass and this door will earn its keep.

Security & Hardware – Multi-point lock hardware engages the active panel at top, bottom, and center with a single handle turn. The locks are concealed inside the profile, not surface-mounted, so there’s nothing for a pry bar to grab. The passive panel secures with flush bolts into the header and threshold. It’s a more secure configuration than a standard deadbolt French door, and it looks cleaner in the process.

Color & Glass Options

The VLX 100 comes in six finishes, and each one changes the personality of the door. Premium Black is the strongest choice for modern and transitional homes; it creates a crisp frame around the glass and anchors the opening visually. Pure White suits traditional and Farmhouse-style homes around San Jose, especially when the interior trim is already white. Anodized Silver is the classic aluminum look, and it’s the most forgiving finish if the door gets hard use from kids and pets. Bronze reads rich and slightly moody – it pairs well with homes in the Cambrian and Campbell areas that have darker exterior paint palettes. Champagne is a warmer metallic that works beautifully on Spanish Revival and Mission-style homes, which we see a lot of throughout San Jose. Teak Wood is a wood-grain finish on aluminum, which gives you the look of a high-end mahogany door without the rot, warping, or refinishing cycle.

Glass choice depends on where the door lives. Clear is the default for maximum light transfer. Low-E is the energy-performance upgrade we recommend for any door with western or southern exposure in San Jose. Tempered glass is required by code in doors and adjacent sidelites, so we include it by default. Laminated adds the acoustic and impact-resistant benefits. Frosted and Obscure glass give privacy without losing light, which is why people choose them for a door that faces a neighbor’s window or a side-yard walkway.

Installation by Westlight Windows San Jose in San Jose

Here’s the honest truth about aluminum French doors: the product is only as good as the installation. A door that’s set even a quarter-inch out of square will sag, bind, and eventually fail at the hinges. We’ve seen it on doors installed by general contractors who don’t specialize in fenestration. That’s why Westlight Windows San Jose installs every VLX 100 Double Swing door to the letter of AAMA 2400 and AAMA 2410 standards.

Our process starts with a pre-install inspection of the rough opening. We verify the header, the king studs, the trimmers, and the subfloor before any aluminum goes in. If the opening isn’t right, we tell you before we start, not after. Then we set the frame level, plumb, and square, shimming as needed and anchoring according to the manufacturer’s engineering requirements. All perimeter joints get AAMA 812 low-expansion foam sealant, followed by a sill pan flash and back-dam where the door meets the floor. After the panels are hung and adjusted, we run a water test on the threshold and bottom corners, cycle the door repeatedly, and only call the job done when the reveal is even all the way around.

One more thing worth knowing: a manufacturer’s warranty covers defects in the product. It does not cover damage caused by improper installation. If a door is installed out of square or without proper flashing, and it fails, the warranty won’t save you. Hiring Westlight Windows San Jose means the installation is warranty-safe, and we stand behind it with our own workmanship warranty on top of ViewLux’s product coverage. We know San Jose building codes, we know the rough openings in the housing stock from the 1950s through the 1990s, and we know how to make this door work in them.

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 made-to-order product, and typical lead time from order to delivery in the San Jose area runs four to six weeks depending on finish and glass selection. We confirm a firm delivery window when you place your order, and we coordinate installation around your schedule. Call (669) 333-7786 and we can check current production timelines for your specific configuration.

Does the VLX 100 qualify for energy tax credits? The VLX 100 with Low-E glass meets NFRC-rated performance thresholds that often qualify for federal energy efficiency tax credits and local utility rebate programs in California. The exact credit amount depends on the glass package and the specific program year. We can provide the certification documentation for your door, and your tax professional can confirm eligibility. Call (669) 333-7786 to discuss which glass package maximizes your rebate.

What warranty comes with the Double Swing / French Door? ViewLux provides the product warranty on the VLX 100, covering defects in materials and manufacturing on the frame, glass, and hardware. Westlight Windows San Jose provides a separate workmanship warranty on the installation itself. The details of coverage vary by component, and we walk you through the warranty document before you sign anything. Call (669) 333-7786 if you want us to email you a copy.

Can I customize the size? Yes, within the structural limits of the system. The VLX 100 spans up to 96 inches wide in a paired configuration, and height is customized to your rough opening. We don’t force your opening to fit a stock size; we order the door to fit your opening. Standard and custom widths are both available, and we measure everything on site before ordering so there are no surprises on install day. Call (669) 333-7786 to schedule a free measurement.

How do I maintain aluminum frames? Aluminum frames need almost no maintenance beyond occasional cleaning with mild soap and water. The finish is baked on at the factory and won’t peel or require repainting. We recommend checking the weather gaskets once a year and cleaning the threshold track if debris accumulates. The hardware may need minor seasonal adjustment as temperatures shift, which is normal for any French door, and we can handle that during a routine service visit. Call (669) 333-7786 if you notice any binding or sticking.
