Product Overview – VLX 100 Bifold / Folding Door

The VLX 100 exists for one reason: to remove the barrier between inside and outside. Unlike a slider that leaves half the opening blocked, this door folds flat against the jamb or into a pocket, giving you a wall-to-wall opening. In Pasadena, where evening temperatures drop after warm afternoons, that flexibility matters. You can open the entire span for a dinner party, then close just two panels when the breeze picks up off the San Gabriel foothills.

The extrusion wall measures 0.098 inches, which gives each panel real rigidity without the bulky look of older aluminum systems. The profile width is 2.56 inches, so even with six panels stacked, the sightlines stay lean. Buyers choose the VLX 100 over wood bifolds in Pasadena because aluminum doesn’t swell in the rainy season or warp under direct heat. It also resists the fine dust that blows through Altadena and the foothill neighborhoods during Santa Ana events. The panels ride on a low-friction track that stays smooth through years of daily use, and the locking hardware seats firmly without needing a hard slam.

The configurable layout, from two panels to six, means the VLX 100 works on a breakfast nook opening in a Madison Heights bungalow or a full-width great-room wall in a new Pasadena build. For a true seamless indoor-outdoor transition, we often pair the VLX 100 with a flush sill or recessed track, which nearly eliminates the step from flooring to patio.

Performance Features

Thermal Efficiency

The VLX 100 uses thermal break technology inside the extrusion, so the aluminum frame doesn’t conduct heat from outside to inside. With Low-E or laminated glass, the door holds NFRC-rated energy performance that keeps Pasadena homes cooler during July and August without running the AC nonstop.

Acoustic Performance

Laminated glass is available for the VLX 100, and it meaningfully reduces sound transmission. If your Pasadena home sits near Orange Grove Boulevard, the 210, or a busy school zone, this option cuts road and ambient noise while the door is closed. Ask us about pairing laminated glass with a retractable screen during your estimate.

Airtightness & Weather Seal

The VLX 100 is engineered for a tight perimeter seal. On installation, we apply AAMA 812 low-expansion foam sealant to every joint. Combined with factory gaskets at each panel seam, this controls air infiltration and prevents the fine dust and smog particulates common in Pasadena from working through the openings.

Waterproofing

Rain in Pasadena arrives fast and hard between January and March. The door’s drain path, sill design, and our perimeter foam sealing work together to channel water away from the interior. Every installation we perform gets a final water test before we call the job done.

Wind Resistance

The VLX 100 is wind-load rated and built for Southern California’s gust conditions, including the Santa Ana events that whip through the Arroyo Seco and foothill communities in Pasadena. The 0.098-inch wall thickness and reinforced track keep the panel line stable even in a strong crosswind.

Security & Hardware

Each panel locks flush into the track, and the multi-point handle secures the door at top and bottom. Laminated glass is the impact-resistant option, adding real barrier strength against forced entry. Our hardware pre-inspection before install confirms everything seats correctly, so the lock throws smooth every time.

Color & Glass Options

The VLX 100 comes in six finishes. Pure White and Anodized Silver suit the clean-lined Spanish and modern homes across Pasadena. Premium Black is the most requested finish for contemporary remodels in neighborhoods like South Arroyo and Linda Vista, giving the opening a sharp frame. Bronze and Champagne sit warmly against stucco and terra cotta, which makes them a natural fit for Craftsman and Mediterranean homes. Teak Wood is a textured woodgrain finish that matches timber trim on traditional homes without the upkeep of real wood.

On the glass side, Clear maximizes daylight and is ideal for north-facing openings. Low-E is the energy-conscious pick for walls that catch afternoon sun. Tempered is safety glass and is standard for doors. Laminated adds sound dampening and impact resistance, which we recommend for busy streets or homes with young kids. Gray Tint and Black Tint cut glare and are popular on west-facing Pasadena patios where the afternoon sun is intense.

Installation by Lightwell Windows Pasadena in Pasadena

Installation is half the product. A bifold door that’s out of square by even an eighth of an inch will bind, drag, or leak, and most manufacturer warranties are voided by improper installation. We install the VLX 100 to the standard that keeps the warranty valid and the door functioning like new for years.

We start every project with a pre-install inspection of the rough opening. We verify the header, jack studs, and floor condition before ordering the door. Pasadena’s older housing stock, especially Craftsman and Spanish Revival homes, often has settled framing or slightly out-of-level floors. We account for that before the door arrives, not after.

During install, we set the frame level, plumb, and square. The sill goes in level, the side jambs get shimmed and anchored, and the head is checked for straightness. Every perimeter joint receives AAMA 812 low-expansion foam sealant, and we install per AAMA 2400/2410 standards. The panels are hung, aligned, and adjusted so the door folds and glides without resistance. We finish with a water test across the sill and bottom track, then walk you through operating, locking, and maintaining the system. We clean up the job site and haul away all packaging. You call one local Pasadena company for the product, the install, and any future service.
