VLX 100 Double Swing / French Door

VLX 100 Double Swing / French Door in San Antonio, TX | Juniper Windows San Antonio

The VLX 100 Double Swing / French Door is a paired aluminum door system built for wide openings and clean, symmetrical sightlines. San Antonio homeowners choose it for patios, back porches, and interior-to-exterior transitions where a single door feels too narrow. Juniper Windows San Antonio is an authorized ViewLux installation partner, which means we sell the real product, install it to manufacturer spec, and stand behind the work. If you’re pricing out a French door replacement or planning new construction anywhere from Alamo Heights to Stone Oak, call us at (903) 488-7019 for a straight answer and a free estimate.

Product Overview – VLX 100 Double Swing / French Door

The VLX 100 is ViewLux’s paired-door aluminum system. Two door panels meet in the center, both swing open, and the hardware engages across three locking points. In a San Antonio home, that means wide-open airflow in October and a tight seal in August when the AC is working hard.

What pulls people toward this series is the balance of proportions. Each panel matches the other exactly. The vertical stiles and horizontal rails carry the same width across both panels, so the door reads as one architectural piece rather than two separate doors bolted together. That symmetry matters on the back of a house, especially with San Antonio’s mix of Hill Country modern and mid-century ranch styles.

The frame is extruded aluminum with a 0.098-inch wall thickness and a 2.56-inch profile width. That’s a substantial frame. It resists the racking and sagging that cheaper vinyl or hollow-core doors develop after a few Texas summers. The flush threshold sits nearly level with the floor, which keeps the transition smooth for foot traffic, walkers, and wheelchairs. And the multi-point lock hardware is a step up from a single deadbolt: the bolts engage at the top, middle, and bottom of the active panel in one throw of the handle.

Juniper Windows San Antonio stocks and installs this door because it holds up. Aluminum does not swell in humidity, does not bow under direct sun, and does not need repainting every three years. For a city where a west-facing back door can hit 140 degrees in July, that engineering matters more than most buyers realize at first glance.

Performance Features

Thermal Efficiency – The VLX 100 uses thermal break technology, which separates the interior and exterior aluminum faces with a non-conductive material. That break slows heat transfer through the metal. NFRC-rated energy performance means the numbers are independently tested, not marketing claims. In San Antonio, where cooling costs drive utility bills from May through September, that thermal break pays for itself over the life of the door.

Acoustic Performance – Aluminum frames with tight perimeter seals reduce outside noise transmission. If you live near Loop 410, IH-10, or any of San Antonio’s busier surface streets, the sound control rating on this door is worth asking about. Coupled with laminated glass, the acoustic performance improves noticeably.

Airtightness & Weather Seal – The VLX 100 is designed to keep conditioned air in and outside air out. All perimeter joints are sealed with AAMA 812 low-expansion foam, which fills gaps that conventional caulk misses. Airtightness ratings on this door category are measured and tested, and this series performs at the top of its class.

Waterproofing – Blowing rain against a west-facing back door is common in San Antonio spring storms. The VLX 100’s sill design and perimeter sealing direct water away from the interior. Our installers run a final water test after every installation to verify the seal before we call the job done.

Wind Resistance – Wind-load ratings matter in South Texas. The VLX 100 is tested for wind conditions that match local climate data for San Antonio and surrounding counties. For homes in more exposed areas like Helotes or the far northwest near Government Canyon, we can specify laminated glass for added impact resistance.

Security & Hardware – The multi-point lock engages three separate bolts when you lift the handle. That spreads force across the full door height rather than relying on a single deadbolt at the center. Aluminum frames resist kick-in attempts better than wood or vinyl. For San Antonio homeowners, that hardware upgrade is one of the quiet reasons this door outsells single-point options.

Color & Glass Options

Six frame finishes cover most of what San Antonio architecture demands. Premium Black is the default for modern and contemporary homes, especially paired with black window frames. Pure White suits traditional ranches and Spanish colonial exteriors. Anodized Silver gives a clean commercial look that works well on mid-century homes in neighborhoods like Oak Park and Northwood. Bronze adds warmth to brick homes from the 70s and 80s. Champagne is the softer alternative to silver, popular on Hill Country homes with limestone exteriors. Teak Wood is a wood-grain finish that gives the aluminum frame a timber appearance without the maintenance.

Glass selection depends on what the door faces. Clear works for shaded north-facing openings. Low-E is the standard choice for most San Antonio installs because it cuts solar heat gain. Tempered glass is required by code in most door applications and is included by default. Laminated glass adds impact resistance and sound damping, useful for storm-prone areas or homes near rail lines. Frosted and Obscure glass give privacy for bedroom or bathroom-adjacent doorways while still letting light through.

Installation by Juniper Windows San Antonio in San Antonio

A French door is only as good as the opening it’s set into. We have replaced dozens of VLX 100 doors in San Antonio homes where the previous door failed not because the product was bad, but because the installation was sloppy. Water got in. The frame shifted. The panels stopped meeting in the middle.

Juniper Windows San Antonio installs the VLX 100 Double Swing / French Door to AAMA 2400/2410 standards on every job. That means we start with a pre-installation inspection of the rough opening. If the opening is out of square, we correct it before the door goes in. The frame is set level, plumb, and square using shims and measurements, not eyeballing. Then we seal the perimeter with AAMA 812 low-expansion foam on every joint, inside and out. Low-expansion means the foam will not bow the frame as it cures, a common failure point with cheap installs. After the panels are hung and adjusted, we run a water test around the sill and side jambs, check the multi-point lock alignment, and clean up the site before we leave.

San Antonio has its own set of realities: clay soils that shift, summer heat that expands aluminum, and fall storm seasons that test every seal. Our installs account for all three. Improper installation voids the manufacturer warranty on ViewLux products, which is why we recommend professional installation even if you find the door at a discount somewhere else. The warranty is only as good as the crew that puts it in.
