Product Overview – VLX 100 Bifold / Folding Door

The VLX 100 is designed around one idea: the wall disappears. Panels fold along a floor track or top-hung system and stack neatly to the side, giving you a clear opening up to 20 feet wide. There’s no center post, no fixed mullion, no visual break between inside and outside. That’s the reason architects in Los Angeles keep specifying this series for hillside remodels, mid-century updates, and new ADU builds. The accordion-style aluminum construction keeps the panels light enough to move easily, yet rigid enough to hold straight and true through years of sun exposure and temperature swings.

Buyers choose the VLX 100 over sliding doors when they want the fullest possible opening. A sliding door gives you about half the span. A bifold gives you the entire span. For a Los Angeles home with a deck, a pool, a canyon view, or a courtyard, that difference changes how the house lives. The frames are extruded aluminum with a wall thickness of 0.098 inches and a profile width of 2.56 inches. That’s a substantial section, which matters when panels are 8 to 10 feet tall and the wind pushes against them. The engineering here favors long-term performance over a lighter, flimsier frame.

Westlight Windows Los Angeles installs the VLX 100 across Los Angeles County as a certified ViewLux partner. The partnership means straightforward access to the product line, direct factory support on technical details, and installation that keeps the manufacturer warranty fully intact. We handle the measuring, the ordering, the delivery, and the install. You handle choosing the finish and picking the day we start. Call us at (213) 810-3461 to begin.

Technical Specifications

The VLX 100 is offered in several configurations to fit different openings and architectural styles. Below are the key specifications, reworded from the ViewLux product sheet for clarity. These are the numbers we quote from every day here in Los Angeles.

• Wall thickness: 0.098 inches of extruded aluminum, giving the frame serious torsional rigidity.
• Profile width: 2.56 inches, a visible but not bulky frame that suits modern openings.
• Maximum span: Up to 20 feet wide, configurable by panel count and height.
• Track configurations: 2-panel, 3-panel, 4-panel, 5-panel, or 6-panel systems.
• Glass options: Clear, Low-E, Tempered, Laminated, Gray Tint, Black Tint.
• Color and finish options: Premium Black, Pure White, Anodized Silver, Bronze, Champagne, Teak Wood.
• Screen options: Retractable Screen, or none.
• Performance standards: Thermal break technology, NFRC-rated energy data, AAMA 2400/2410 installation compliance.

Panel count determines the stacking space. A 4-panel unit on a 16-foot opening stacks into roughly four feet of wall space, depending on panel width. A 6-panel unit on a 20-foot opening stacks similarly. We calculate this during our free measurement visit anywhere in Los Angeles.

Performance Features

Thermal Efficiency. The VLX 100 carries a true thermal break inside the aluminum frame, which stops heat from conducting between the exterior and interior faces. That break, combined with Low-E glass, holds conditioned air inside your Los Angeles home during August heat and keeps the chill out on those 45-degree January mornings in the Valley. The system is NFRC-rated, so we can provide actual performance data for your specific glass package.

Acoustic Performance. Laminated glass changes the noise picture entirely. For homes near the 405, the 101, or LAX flight paths, laminated glass in the VLX 100 drops outside noise noticeably. The airtight perimeter seal also helps, because sound travels through gaps as much as glass. We recommend laminated glass for any Los Angeles home within earshot of a freeway or flight corridor.

Airtightness & Weather Seal. Every perimeter joint gets AAMA 812 low-expansion foam sealant, the standard that prevents air movement and the dust that comes with it. The panel-to-panel joints use interlocking weatherstripping that compresses when the door closes. In Los Angeles, where wildfire smoke and Santa Ana dust are seasonal realities, an airtight bifold door is more than a comfort feature. It’s a health feature.

Waterproofing. The VLX 100 is designed to shed water, not trap it. The sill system, threshold, and weep drainage work together so that rain hitting the door face exits the system at the bottom. Our installation includes a water test after the door is set, before we call the job done. Los Angeles gets most of its rain in a handful of winter storms, and a door that leaks will show it fast.

Wind Resistance. Aluminum sections this thick handle wind loading well, which matters on Los Angeles hillsides and canyon exposures where gusts come hard. The VLX 100 is wind-load rated, and we specify the correct panel configuration and hardware for your elevation and exposure. A door on a protected Atwater Village bungalow has different requirements than a door on a ridge in Mount Washington.

Security & Hardware. Multi-point locking hardware, not just a single latch, secures the panels when the door is closed. For Los Angeles homeowners, that’s a meaningful difference. A properly locked bifold is a poor point of entry for anyone who shouldn’t be there. We also handle the hardware adjustment at installation and show you how it should feel when it’s right.

Color & Glass Options

Premium Black and Pure White are the two most common VLX 100 finishes in Los Angeles right now, and they work on opposite ends of the design spectrum. Black frames on a white stucco house create a clean architectural contrast that suits mid-century, Spanish modern, and contemporary builds. Pure White frames blend into a light interior wall and keep the eye on the view, not the door. If you want something quieter, the Anodized Silver finish reads almost like clear metal and stays understated.

Bronze and Champagne suit warmer palettes and older Los Angeles homes with wood trim or beige interiors. Teak Wood is a powder-coated finish that approximates wood grain, giving you the warmth of timber without the maintenance, and it’s a popular choice in Sherman Oaks, Studio City, and Pasadena-adjacent homes. All six finishes are factory-applied and carry the same warranty.

For glass, Tinted options like Gray and Black reduce solar heat gain and add daytime privacy, which helps with west-facing Los Angeles rooms. Low-E improves insulation year-round, and Tempered glass is required by code in many door applications for impact safety. Laminated glass adds both acoustic damping and impact resistance, and it’s the right choice for homeowners who want security and sound control in one package.

Installation by Westlight Windows Los Angeles in Los Angeles

We install every VLX 100 to the AAMA 2400/2410 standard, which is a set of installation practices for window and door systems, and we don’t cut corners on any of it. The process starts with a site visit, where we measure the rough opening, check the floor and header for level, and look at the surrounding wall construction. That tells us what kind of substrate we’re fastening into, whether it’s wood framing, steel, or concrete, and what flashing detail we need. Los Angeles building stock varies wildly from 1920s Spanish in Echo Park to 2010s hillside contemporary in Beachwood Canyon, and the install details differ accordingly.

We set the frame level, plumb, and square, shimming as needed and anchoring into structure, not drywall. The perimeter joints are sealed with AAMA 812 low-expansion foam, which doesn’t distort the frame as it cures. We flash the sill and head correctly, which is where most bifold leaks originate when they’re installed quickly. Then we hang the panels, adjust the hinges and rollers, and run a water test to confirm drainage works as designed.

The reason this matters is that improper installation voids the manufacturer warranty. If a door is installed out of square, panels bind. If the sill is flashed wrong, water gets behind it. If the frame is under-shimmed, it sags over time. Westlight Windows Los Angeles takes responsibility for the install as the authorized ViewLux partner in Los Angeles, which means no finger-pointing between a supplier and a subcontractor if something needs adjusting. It’s our name on the work.

Los Angeles code requirements also come into play, particularly around tempered glass in doors and seismic fastening. We’re familiar with LADBS requirements and we pull permits where the project calls for them. If your project involves a structural engineer, we coordinate with them directly.

Frequently Asked Questions – VLX 100 Bifold / Folding Door

What is the lead time for the VLX 100 bifold door? Most VLX 100 orders arrive in 4 to 8 weeks from the date the order is placed with ViewLux, depending on panel count, finish, and glass selection. Custom sizes and specialty glass can extend that. We confirm lead times before you commit. Call (213) 810-3461 and we’ll give you the current factory schedule for your configuration.

Does the VLX 100 qualify for energy tax credits? The eligibility depends on the glass package and the door’s NFRC ratings. A Low-E, thermally broken configuration may qualify for federal energy tax credits, and some California programs offer additional rebates for high-performance glazing. We can provide the NFRC performance data for your chosen configuration so you can present it to your accountant or check current IRS eligibility. Call (213) 810-3461 to discuss.

What warranty comes with the VLX 100 bifold door? The VLX 100 carries a ViewLux manufacturer warranty on the frame, glass, and hardware, and the exact terms vary by component. The warranty is only valid if the door is installed to the manufacturer’s specifications by an authorized installer, which is what Westlight Windows Los Angeles is. Our installation workmanship is also backed by our own guarantee. Contact us at (213) 810-3461 for the specific warranty documents.

Can I customize the size of the VLX 100? Yes. The system spans up to 20 feet wide, and panel count, panel width, and panel height are all configurable within that span. That means we can build a 3-panel unit for a 9-foot opening or a 6-panel unit for an 18-foot wall. We’ll measure the actual opening and give you the maximum clear width for your space. Call us at (213) 810-3461 and we’ll walk the numbers with you.

How do I maintain aluminum frames? Wash the frames with mild soap and water, and wipe down the track every few months so debris doesn’t build up under the rollers. Test the weatherstripping seasonally. Aluminum doesn’t rot or warp like wood, which is one reason the VLX 100 performs well in Los Angeles’s dry heat and coastal salt air. We’ll walk you through the full care routine at installation. Questions? Call (213) 810-3461.
