Product Overview – VLX 100 Bifold / Folding Door

The VLX 100 is built around a simple idea: a wall should be able to get out of the way. Where a traditional sliding door leaves two-thirds of the opening blocked by glass, a bifold folds the panels flat against the jamb and clears nearly the entire span. In San Antonio, where fall evenings and spring mornings are the best weather of the year, that difference changes how a home lives.

This series is aluminum through and through. The extrusion walls measure 0.098 inches thick, and the profile face is 2.56 inches wide. That is a heavier frame than what you’ll find on entry-level patio doors, and the weight shows up in the way the panels track: straighter, quieter, less deflection over time. The hardware is engineered to carry glass-loaded panels without sagging at the hinges, which is the failure point on cheaper bifold systems.

Visually, the VLX 100 reads clean. Narrow sightlines, flat faces, no decorative clutter. In a modern Hill Country house, it looks like a design feature. In a traditional San Antonio ranch, it reads as a purposeful upgrade rather than a style clash. Buyers choose this series because it spans wide openings, handles the Texas sun without warping, and stays square year after year. It delivers the wall-to-wall opening and seamless indoor-outdoor living that the product is known for, without the maintenance profile of wood.

We specify this door most often for covered patios, pool-facing great rooms, and remodeled kitchens that open to an outdoor cooking area. It is also a natural fit for restaurants, tasting rooms, and boutique retail spaces around the San Antonio area that want a storefront that opens to the street.

Technical Specifications

The VLX 100 is a configurable system. Here is what the engineering actually allows:

• Wall thickness: 0.098-inch aluminum extrusion walls, which is heavier than typical residential patio door framing.
• Profile width: 2.56-inch face width on panels and jambs for a slim, modern sightline.
• Maximum span: Up to 20 feet of total opening width, depending on panel count and glass weight.
• Track configurations: Available in 2-panel, 3-panel, 4-panel, 5-panel, and 6-panel layouts. Most San Antonio homes land at 3 or 4 panels.
• Glass options: Clear, Low-E, Tempered, Laminated, Gray Tint, and Black Tint.
• Finish options: Premium Black, Pure White, Anodized Silver, Bronze, Champagne, and Teak Wood.
• Screen options: Retractable screen available, or none for a fully open look.
• Performance: Thermal break technology, NFRC-rated energy performance, AAMA 2400/2410 installation standard compliance, and AAMA 812 low-expansion foam sealant specified at every perimeter joint.
• Impact resistance: Laminated glass option available for storm-rated and security applications.
• Wind load: Rated to meet San Antonio and Bexar County wind-load requirements for the specific site.

Performance Features

Thermal Efficiency – The VLX 100 uses a thermal break between the interior and exterior aluminum faces. That separation cuts conductive heat transfer, which is the difference between a frame that bakes in a San Antonio August and one that stays touchable. NFRC-rated performance means you can compare real numbers, not marketing language.

Acoustic Performance – Laminated glass and tight perimeter sealing reduce what gets through the closed door. If you live near Loop 410, I-10, or a school zone in San Antonio, the sound control difference is noticeable. The frame seals are engineered to stay compressed rather than flattening out after a year of use.

Airtightness & Weather Seal – Every perimeter joint gets AAMA 812 low-expansion foam sealant, and the gaskets are compression-fit rather than surface-contact. That means less dust from Texas winds, fewer drafts in January, and a door that does not whistle when the pressure changes. Airtightness ratings for this series hold up over repeated cycling.

Waterproofing – The sill, the panel joints, and the head condition are built to shed water rather than trap it. Proper installation per AAMA 2400/2410 matters as much as the sill design itself. When installed correctly by Hale Windows San Antonio, the door handles San Antonio’s monsoon-season downpours without weeping into the room.

Wind Resistance – Aluminum frames carry glass under wind load without flexing the way vinyl does. The VLX 100 is wind-load rated for the specific site conditions, which matters in San Antonio when spring fronts roll through with 50 mph gusts. The laminated glass option adds further resistance and stays in the frame if impacted.

Security & Hardware – Multi-point locking hardware engages at the top and bottom of each panel, not just the center. Laminated glass is the standard security upgrade we recommend: it resists forced entry far longer than tempered alone and holds together if broken. The hardware on this series is commercial-grade, built to cycle thousands of times without slop developing in the hinges.

Color & Glass Options

Six finishes cover most design directions. Premium Black is the most requested finish in San Antonio right now, especially in Alamo Heights and Terrell Hills where black-framed modernism has taken hold. Pure White suits traditional homes and bright rooms where the door should blend into the trim. Anodized Silver reads industrial and clean, a good match for mid-century homes. Bronze is the quiet choice: darker than silver, warmer than black, forgiving of dust and fingerprints. Champagne pairs well with warm stucco and limestone. Teak Wood is a wood-look finished aluminum, so you get the appearance without the rot, warp, or paint cycle that real wood demands in San Antonio humidity.

Glass is equally situational. Clear maximizes light, but expect more heat gain. Low-E is what we recommend for west-facing openings in San Antonio; it reflects infrared while staying visually transparent. Tempered is required by code for door panels and is included standard. Laminated adds impact resistance and sound dampening. Gray Tint and Black Tint cut glare and heat dramatically, which matters on unshaded south-facing patio openings. We help you pick the combination that fits the exposure, the view, and the energy goal; call (361) 348-8929 to walk through samples.

Installation by Hale Windows San Antonio in San Antonio

A bifold door lives or dies on installation. We have seen manufacturer warranties voided because a door was set out of level, shimmed wrong, or sealed with the wrong product. The panels do not fold. The lock does not align. The sill leaks. The manufacturer refuses the claim because the installation was not performed to AAMA 2400/2410. That is a five-figure mistake.

Our install process for the VLX 100 in San Antonio starts before the door is even ordered. We measure the rough opening in three places, check the floor for level across the full span, and confirm the header is straight and structurally adequate for a 20-foot opening if that is the direction you are headed. If the opening needs structural work, we flag it before the panels arrive, not after.

On install day, we set the frame level, plumb, and square, then shim at load points, not just where convenient. Every perimeter joint gets AAMA 812 low-expansion foam, which seals without bowing the frame. We flash the head, the jambs, and especially the sill. In San Antonio, the sill detail matters most; our rain events are short and violent, and a poorly flashed sill is the first place a leak shows up. We water-test the sill before we call the job done, run the panels through their full range of motion, and adjust the hinges until every panel seats square. Then we haul off everything and leave the opening clean.

Because we are the authorized installation partner for ViewLux in San Antonio, our installs are warranty-safe by default. You get one company to call if anything needs attention, not a manufacturer and an installer pointing at each other across state lines.

Frequently Asked Questions – VLX 100 Bifold / Folding Door

What is the lead time for the VLX 100 Bifold / Folding Door?

Lead time on the VLX 100 typically runs 4 to 8 weeks from the time we finalize your order, depending on panel count, glass, and finish. Custom finishes and laminated glass can add time. We confirm the current lead time before you commit. Call (361) 348-8929 and we’ll get you a real delivery window based on your exact configuration.

Does the VLX 100 qualify for energy tax credits?

It can, depending on the glass package and the NFRC ratings for your specific configuration. Low-E glass in an NFRC-certified thermal-break frame is the combination that typically qualifies. We’ll provide the documentation you need for your tax preparer when we quote your door.

What warranty comes with the VLX 100 Bifold / Folding Door?

ViewLux provides a written manufacturer warranty on the door system, covering the frame, glass, and hardware. Our installation is covered by Hale Windows San Antonio’s workmanship warranty. The critical detail: the manufacturer warranty applies when the door is installed to AAMA standards, which is exactly how we install every VLX 100.

Can I customize the size of the VLX 100?

The panel system is configurable from 2 panels up to 6, spanning up to 20 feet wide. Panel widths adjust within the system’s engineering limits, so your door is sized to your opening rather than forcing your opening to fit a stock size. We measure first and order second.

How do I maintain aluminum frames in San Antonio’s climate?

Aluminum needs about ten minutes a year: wipe the tracks clear of debris, lubricate the rollers and hinges with a dry silicone, and inspect the perimeter sealant. San Antonio dust and oak pollen collect in the bottom track, and a clogged track is the fastest way to make a bifold bind. We include a maintenance walkthrough at installation and will service the hardware for you if you’d rather not do it yourself.
