VLX 100 Bifold / Folding Door in Riverside, CA | Westlight Windows Riverside
The VLX 100 bifold door is an accordion-style aluminum system that folds panel-by-panel to one side, opening an entire wall to the outdoors. Riverside homeowners choose it for patios, backyard kitchens, pool access, and great-room transitions where a standard slider feels too cramped. We’re Westlight Windows Riverside, an authorized ViewLux installation partner serving Riverside since day one with factory-backed workmanship. Every VLX 100 we install follows AAMA 2400 standards, so the warranty stays intact and the door operates the way the engineers intended. Call (760) 624-3669 for a free on-site measurement and written quote.
Product Overview – VLX 100 Bifold / Folding Door
The VLX 100 is built for one purpose: taking a wall out of the equation. Unlike multi-slide doors that stack behind each other, a bifold folds like an accordion and parks neatly against the jamb, leaving a nearly uninterrupted opening. That’s the wall-to-wall opening Riverside buyers tell us they want when they describe moving between a living room and a covered patio without stepping through a narrow doorway.
Architecturally, this door fits modern ranch homes in Canyon Crest, mid-century builds in the Wood Streets, and newer Spanish-style construction throughout Riverside’s hillside communities. It reads as a design statement more than a door, especially in the darker finishes like Premium Black or Bronze, which frame the opening the way a gallery frames artwork.
The engineering underneath is straightforward and honest. Extruded aluminum profiles with a 0.098-inch wall thickness handle years of sun exposure without sagging. At 2.56 inches wide, the profile is slim enough to keep sightlines clean but deep enough to hold laminated glass when impact resistance matters. Each panel rides on a precision track system, and we configure the door in two, three, four, five, or six panel layouts depending on your opening width. The result is a door that opens smoothly with one hand and locks with confidence when closed.
Because Westlight Windows Riverside installs the VLX 100 as an authorized partner, you get the product as designed, not as approximated by a general contractor who touches one bifold a year. That matters more than most people realize.
Technical Specifications
The VLX 100’s numbers tell the story. Here’s what you’re getting when you order this system through us in Riverside:
- Wall thickness: 0.098-inch extruded aluminum
- Profile width: 2.56 inches per panel stile
- Maximum span: Up to 20 feet wide per opening
- Track configurations: 2-panel, 3-panel, 4-panel, 5-panel, and 6-panel systems
- Glass options: Clear, Low-E, Tempered, Laminated, Gray Tint, Black Tint
- Finishes: Premium Black, Pure White, Anodized Silver, Bronze, Champagne, Teak Wood
- Screen options: Retractable screen or none
- Performance compliance: NFRC thermal ratings, AAMA 2400/2410 installation standard, AAMA 812 low-expansion foam sealant at all perimeter joints
Track configurations are worth a closer look. A 2-panel setup suits a smaller opening, around six to eight feet, where you want the simplest possible operation. By the time you reach a 20-foot span, you’re typically looking at a 5 or 6-panel configuration, and panel count affects both price and how the door stacks when fully open. We’ll walk through that at the estimate.
How Much Does the VLX 100 Bifold Door Cost in Riverside?
In Riverside, a VLX 100 bifold door typically runs $1,100 to $1,800 per linear foot installed, depending on panel count, glass package, and finish. A standard 12-foot, 4-panel system with Low-E glass and a powder-coat finish usually lands between $13,000 and $19,000. A 20-foot, 6-panel configuration with laminated glass and a retractable screen pushes toward the top of that range and sometimes beyond.
| Component | Typical Range (Riverside, CA) |
|---|---|
| Base VLX 100 door (per linear foot) | $950 – $1,350 |
| Low-E glass upgrade (per panel) | $180 – $320 |
| Laminated impact glass (per panel) | $380 – $650 |
| Retractable screen | $1,200 – $2,800 |
| Premium finish upgrade | $400 – $1,100 |
| Installation (AAMA 2400 compliant) | $2,500 – $5,500 |
These are Riverside market numbers we quote regularly. Your exact price depends on the rough opening condition, structural header work, stucco or drywall returns, and whether we’re replacing an existing slider or cutting new framing. Call (760) 624-3669 and we’ll give you a line-item quote, not a ballpark.
Performance Features
Thermal Efficiency. The VLX 100 uses a thermal break within the aluminum profile, separating interior and exterior metal to stop heat transfer. NFRC-rated performance means the door qualifies for energy programs and keeps Riverside’s triple-digit August heat from bleeding through the frame.
Acoustic Performance. Laminated glass paired with compression gaskets at every panel joint meaningfully drops outside noise. If you live near the 91 or under a flight path into March Air Reserve Base, this is the glass spec you want.
Airtightness & Weather Seal. Each panel edge carries a continuous bulb seal, and the perimeter gets AAMA 812 low-expansion foam at installation. No drafts at the threshold, no dust intrusion during Santa Ana winds in Riverside.
Waterproofing. The sill design channels water outward through weep ports, while the interlocking panel profiles create a shingled barrier against driven rain. This is tested, not assumed, and we verify it during our final water test on every installation.
Wind Resistance. The VLX 100 is wind-load rated for Inland Empire requirements. Riverside sees consistent afternoon winds through the passes, and a wide bifold is a big sail. The multi-point locking system and reinforced stiles keep panels rigid under load.
Security & Hardware. Multi-point locks engage at the top, bottom, and center of the active panel. Hinges are stainless steel with load-rated bearings. The door locks like a serious entry point, not a partition. Tempered or laminated glass adds another layer of deterrence.
Color & Glass Options
Six finishes cover most architectural palettes in Riverside. Premium Black and Anodized Silver are the modern defaults, pairing cleanly with white stucco and minimalist railings. Bronze warms up ranch-style homes and works with brick or wood siding. Champagne and Teak Wood suit traditional or Tuscan-style exteriors, while Pure White disappears into light interiors and Spanish Revival facades.
On glass, start with function. Low-E is the Riverside baseline, reflecting solar heat while keeping views clear. Tempered is required on doors by code and comes standard in most configurations. Laminated adds impact resistance and noise reduction; we recommend it for second-story balconies or openings facing busy streets. Gray Tint and Black Tint cut glare for west-facing patios that get brutal afternoon sun. Clear is the no-frills choice for shaded courtyards where light matters more than heat control.
Installation by Westlight Windows Riverside in Riverside
Most bifold door failures trace back to installation, not manufacturing. A panel that drags, a lock that won’t engage, a corner that leaks; these are almost always the result of an out-of-square rough opening or skipped sealing. That’s the gap we close.
Our process starts with a pre-install inspection of the rough opening. We check the header, the king and jack studs, and the floor for deflection. Then we set the frame level, plumb, and square, shimming and anchoring to the structural framing, not the trim. Panel alignment follows the track, and we adjust each hinge and roller until the door folds and glides without resistance.
Sealing gets the same discipline. Every perimeter joint receives AAMA 812 low-expansion foam, with an exterior-grade sealant cap at the sill, jambs, and head. We install per AAMA 2400/2410, the industry standard for window and door installation, and we run a final water test on the sill under simulated rainfall before we pack up. Cleanup is part of the job, not an afterthought.
Riverside’s climate makes this process non-negotiable. Summer heat cycles expand aluminum, winter dampness settles framing, and Santa Ana winds test every seal. A door set properly handles all of it. One set even half a degree out of square will bind within a season or two. If the door wasn’t installed by an authorized partner like Westlight Windows Riverside, the manufacturer warranty may not cover the repair. We protect the warranty because we follow the book.

What is the lead time for the VLX 100 Bifold / Folding Door? The VLX 100 typically takes 6 to 10 weeks from order to delivery at our Riverside warehouse, depending on your glass package and finish. Custom sizes and six-panel configurations add about two weeks. We confirm a delivery window when you place the order. Call (760) 624-3669 to start the process and lock in a timeline.
Does the VLX 100 qualify for energy tax credits? The VLX 100 qualifies for federal energy credits when ordered with Low-E glass and installed in a primary residence, because the door meets NFRC-rated thermal performance standards. We provide the manufacturer certification statement you’ll need for tax filing. Call (760) 624-3669 and we’ll walk you through which configs qualify.
What warranty comes with the VLX 100 Bifold / Folding Door? The VLX 100 carries a manufacturer’s warranty on the frame, glass, and hardware when installed by an authorized partner.

How do I maintain aluminum bifold door frames?
