Product Overview - VLX 100 Bifold / Folding Door

The VLX 100 is designed for one thing: a wide-open opening. When fully folded, the panels stack tightly against one side, leaving almost the entire span clear. No center post, no narrow pass-through. That’s the difference between a patio door and a bifold, and it’s the main reason Los Angeles homeowners choose this series for kitchens that spill out to the backyard, dining rooms that open to a canyon view, and pool-facing great rooms where the indoor-outdoor flow matters every single day.

What makes this door worth a serious look is how ViewLux engineers the frame. The aluminum profile measures 2.56 inches wide and carries a 0.098-inch wall thickness. That’s a sturdier extrusion than what you’ll find on most off-the-shelf folding doors, and it matters when you’re spanning 16 or 20 feet of glass. The panels move on a smooth track system that’s available in 2-panel through 6-panel configurations, so the door works as well on a modest Venice Beach walkout as it does on a broad Brentwood rear elevation. We install it in Los Angeles homes where the opening gets used daily, and it holds up.

What we hear most from our Los Angeles customers is that they want the indoor-outdoor lifestyle without the door fighting them every time they reach for the handle. The VLX 100 folds with one hand. It closes with a solid feel. And because it’s aluminum, it won’t warp or swell the way old wood patio doors do after a few seasons of coastal humidity and sun. If you’ve ever struggled with a sticking door in a Los Angeles summer, you understand.

Technical Specifications

Here’s what the VLX 100 brings out of the box, in plain terms. These are the numbers our team works with when we plan an installation in Los Angeles.

• Frame profile: 2.56 inches wide, extruded aluminum
• Wall thickness: 0.098 inches, built for wide spans and heavy glass
• Panel configurations: 2, 3, 4, 5, or 6 panel tracks
• Maximum span: Up to 20 feet wide, depending on panel count and glass package
• Glass options: Clear, Low-E, Tempered, Laminated, Gray Tint, Black Tint
• Finish options: Premium Black, Pure White, Anodized Silver, Bronze, Champagne, Teak Wood
• Screen options: Retractable screen, or no screen
• Performance: NFRC-rated thermal break, AAMA 2400/2410 installation standard compliance, AAMA 812 foam sealant on all perimeter joints

Each configuration changes the panel widths and stack depth, so we always confirm the rough opening before finalizing a Los Angeles project. What fits as a 4-panel in an Eagle Rock mid-century may need to be a 5-panel in a newer Playa Vista build with a wider opening.

Performance Features

Thermal Efficiency - The VLX 100 uses a thermal break inside the aluminum frame. That break interrupts the heat path that bare aluminum is known for, which is why aluminum doors in Los Angeles used to bake in the afternoon sun. Pair the thermal break with a Low-E glass package and you get NFRC-rated performance that keeps the west-facing rooms in Los Feliz cooler from about 2 p.m. onward.

Acoustic Performance - Living near the 405 or under the flight path into Burbank will make you care about sound control. Laminated glass is the upgrade to choose for the VLX 100 when outside noise is part of daily life. It doesn’t eliminate traffic or airplane noise, but it cuts the constant hum. We’ve installed these in Westchester, near LAX, and the difference is immediately noticeable.

Airtightness & Weather Seal - The door’s weatherstripping runs continuously along the panel edges and threshold. That’s what keeps conditioned air inside and the June gloom out. When we install the VLX 100 in Los Angeles, we set the panels so the gaskets compress evenly along the full run. Even gasket pressure is the difference between a door that seals quietly and one that lets a whisper of air through the bottom corner.

Waterproofing - Los Angeles may not get much rain, but when it does, it comes sideways off the Pacific. The VLX 100 is built with sills and drainage channels that shed water away from the threshold rather than collecting it against the interior floor. Proper installation makes or breaks this. We seal every perimeter joint with AAMA 812 low-expansion foam, then add a continuous bead of sealant at the sill. No shortcuts there.

Wind Resistance - A door spanning 15 or 20 feet catches a lot of wind. The VLX 100 is wind-load rated for the requirements we see in Los Angeles building departments. For hillside homes in Sherman Oaks or Studio City where wind gusts come up the canyon at night, a laminated glass upgrade adds impact resistance on top of the wind rating.

Security & Hardware - Multi-point locks engage at the top and bottom of the operating panel, not just the center. The hardware on the VLX 100 is substantial, and the panels ride on rollers sized to carry the glass weight without sagging. If you live in Los Angeles and leave your folding door open for hours at a time, the hardware will see daily use. This one is built for it.

Color & Glass Options

Los Angeles architecture bounces between crisp white stucco, warm mid-century wood, and black-framed modern boxes. The VLX 100 offers finishes to match each. Premium Black is the most requested finish we order for Los Angeles projects, especially for white-washed exteriors where the dark frames create contrast. Pure White disappears into light walls and suits beach-adjacent homes in Manhattan Beach or Santa Monica. Anodized Silver has a machined look that pairs well with industrial lofts downtown.

Bronze and Champagne lean warmer. Bronze works with Spanish-style homes, especially in the San Gabriel Valley. Champagne is subtle, a step up from silver with a slight gold undertone. Teak Wood is a wood-grain finish applied to aluminum, so it gives you the visual warmth of wood without the maintenance. On any of these finishes, the glass gets specified separately. Clear glass is the baseline. Low-E handles the sun in south-facing rooms. Tempered is code-required for doors and gets you safety compliance. Laminated adds the noise reduction and impact resistance we mentioned earlier. Gray Tint and Black Tint shade the room and give the exterior a sleek, reflective look from the street.

Installation by Westlight Windows & Doors in Los Angeles

A folding door is only as good as its installation. We say this to every Los Angeles homeowner who calls us after seeing a VLX 100 installed poorly somewhere else. Folding doors carry more glass, more weight, and more moving parts than a standard sliding door, and a frame set out of square by a fraction of an inch shows up as sticking panels, uneven gaps, and a door that never feels right.

Our installation process starts with a pre-install inspection of the rough opening. We check the header, the side jambs, and the subfloor for levelness before the door ever comes out of the crate. Then we set the frame level, plumb, and square using shims and anchoring points that suit the structure of the home. Every perimeter joint gets sealed with AAMA 812 low-expansion foam. That foam fills the gaps without pushing the frame out of alignment, and it creates a continuous air and water barrier around the entire opening.

We install to AAMA 2400/2410 standards, which is the installation benchmark that matters for doors and windows in Los Angeles. After the door is anchored and sealed, we test it: panels get opened and closed through the full run, gaskets are checked for even compression, and the sill gets a water test to confirm drainage. Then we clean up, haul the packaging, and leave you with a door that works the way the manufacturer intended. If a folding door is installed incorrectly, the manufacturer warranty won’t cover the repair. That’s the practical reason you want a partner like Westlight Windows & Doors on a Los Angeles VLX 100 project, not a crew that’s never touched one before.

Frequently Asked Questions - VLX 100 Bifold / Folding Door

What is the lead time for the VLX 100 Bifold / Folding Door? Most VLX 100 doors ordered for Los Angeles projects arrive in 4 to 8 weeks, depending on the panel configuration, glass package, and finish selected. Call (903) 354-7134 and we’ll confirm the current production schedule for the exact door you need.

Does the VLX 100 qualify for energy tax credits? It may, if you select a Low-E glass package that meets the current federal efficiency criteria for doors. The eligibility depends on the specific glass and the project year. We can help you confirm whether your Los Angeles project qualifies when we put the quote together.

What warranty comes with the Bifold / Folding Door? The VLX 100 carries a manufacturer’s warranty through ViewLux, and the coverage stays intact as long as the door is installed by an authorized partner like Westlight Windows & Doors. Our Los Angeles installation workmanship is also backed by our own warranty.

Can I customize the size? Yes, within reason. The VLX 100 is built to your rough opening in Los Angeles, not pulled off a shelf. Panel widths adjust across the 2-panel through 6-panel configurations, and the door can span up to 20 feet wide. Call (903) 354-7134 with your rough dimensions and we’ll tell you what’s possible.

How do I maintain aluminum frames? Wash the frames and glass with mild soap and water a few times a year, especially if you live near the beach in Los Angeles where salt air sits on the finish. The rollers and track stay cleaner longer if you sweep the track regularly. No painting, no sealing, no rot treatment, and no warping. It’s one of the reasons aluminum folding doors are popular in Los Angeles.
