Product Overview – VLX 100 Arched / Custom Door

The VLX 100 series is built around one idea: a curved doorway should be as strong and precise as anything square. Most arched doors are fabricated by cutting and welding straight sections, which leaves small inconsistencies in the arc. The VLX 100 is different. The aluminum is CNC-bent, meaning a machine controls the bend radius continuously along the entire curve. The result is an arc with no flat spots, no weld seams disrupting the profile, and no visual wobble when you sight down the frame.

This matters more than buyers realize. Aluminum is unforgiving. If a bend is off by even a fraction of a degree, the door will bind, the weather seal won’t seat, and the lock won’t engage cleanly. The VLX 100 avoids all of that through controlled fabrication. The profile width measures 2.56 inches, giving the door a slender, architectural look without sacrificing rigidity. Wall thickness on the aluminum extrusion is 0.098 inches, which is substantial for a residential entry door and contributes to both structural stiffness and sound isolation.

Architecturally, this door fits San Antonio homes in specific ways. We see it on Spanish Colonial and Mission-style entries where the arch echoes the original masonry openings. We see it on Tuscan and Mediterranean builds in The Dominion and Cordillera Ranch. And increasingly, we see it on modern farmhouse and contemporary homes where the arch is a deliberate contrast against straight rooflines. The maximum span is custom-fabricated to order, so you’re not limited to catalog sizes. If your opening is unusual, we measure it and the door is built to match.

Performance Features

Performance on an arched door comes down to engineering details most people never see. Here’s what the VLX 100 delivers once it’s installed in your San Antonio home.

Thermal Efficiency

The frame carries a thermal break that separates the interior and exterior aluminum faces. Without it, aluminum conducts heat straight through, baking your entry on August afternoons. The thermal break interrupts that path, and NFRC-rated performance documentation backs up the energy numbers. For a south-facing entry in San Antonio, this is the difference between a front door you can touch at 5 p.m. and one you can’t.

Acoustic Performance

Arched doors often leak sound around the curve because the weather seal doesn’t follow the arc tightly. The CNC-bent VLX 100 holds a consistent profile radius, so the seal compresses evenly at every point. That even compression matters for sound control. If you live near a busy San Antonio corridor like Blanco Road or Loop 1604, you’ll notice the drop in road noise the day the door goes in.

Airtightness & Weather Seal

The perimeter joint between frame and rough opening is sealed with AAMA 812 low-expansion foam on every installation we do. This foam expands enough to fill voids but doesn’t push the frame out of alignment. Combined with the compression gaskets built into the door panel, the VLX 100 achieves the airtightness ratings expected from a premium aluminum system.

Waterproofing

San Antonio gets flash floods and driven rain that work their way into weak entry details. An arched door has a natural vulnerability: the top of the arc. The VLX 100 addresses this with a continuous cap flashing detail over the arch and AAMA 812 foam at the perimeter. Water runs off the curve and away from the threshold rather than pooling on top of the frame. During our final water test after installation, we hose the full arc and check the interior before calling the job done.

Wind Resistance

South Texas wind storms are a reality, especially in open developments on the far west side and toward Helotes. The VLX 100 is wind-load rated for local climate requirements, and the 0.098-inch wall thickness holds the door panel rigid under pressure. For homes that want maximum protection, laminated impact glass is available as an option on this model.

Security & Hardware

The multi-point locking system engages at multiple points along the frame rather than a single deadbolt. On a curved door, that matters because a single-point lock on a large panel can flex. Multi-point hardware pulls the panel tight at the top, center, and bottom of the arc, which also improves the seal. Your door isn’t just locked. It’s cinched.

Color & Glass Options

Finish selection is where the VLX 100 becomes yours. Premium Black is the strongest choice in San Antonio’s newer contemporary builds, particularly in Mahncke Park and King William where black-framed entries against light stucco look sharp. Pure White suits traditional Spanish Revival homes and pairs naturally with Saltillo tile and wrought-iron details. Anodized Silver reads as industrial-minimal and works well on mid-century and modern homes. Bronze and Champagne lean warmer, which fits the Hill Country and Mediterranean styles we see in Shavano Park and The Dominion. Teak Wood is a surprising option: an aluminum door with a convincing wood-grain finish that reads warm and natural without the maintenance of actual wood in San Antonio’s UV and humidity.

On glass, your choice should follow function. Clear glass lets maximum light into the entry hall, which is nice for north-facing doors. Frosted and Obscure give privacy without blocking light, which we recommend on entries that face a neighbor’s front door or a busy sidewalk. Low-E glass is the energy play: it cuts solar heat gain, which matters on any San Antonio west-facing entry. Tempered glass is standard for safety. Laminated glass adds impact resistance and sound damping, and it’s the option we suggest for homes in open, wind-exposed areas.

Installation by Lightwell Windows San Antonio in San Antonio

The VLX 100 is only as good as the installation behind it. An arched door is less forgiving than a square one. The rough opening has to be measured exactly, the frame has to be set level, plumb, and square in all three planes, and the seal has to be continuous around the curve. Here’s how we handle it.

We start with a pre-installation inspection of the rough opening. We check the masonry or framing for squareness, measure the arc at multiple points, and confirm the substrate is sound. If something is off, we flag it before the door arrives. Then we set the frame with shims and verify level on the threshold, plumb on both jambs, and square at the head, including along the arc. The perimeter gets AAMA 812 low-expansion foam at every joint, not just where it’s easy to reach. We install the panel, set the hardware, and adjust the hinges until the arc seals evenly.

After trim and threshold work, we run a water test on the full assembly. Then we walk the door with you and make sure you know how the multi-point lock works and what maintenance looks like. We install to AAMA 2400/2410 standards because the ViewLux warranty depends on it. If an arched door is installed by someone who doesn’t understand arc geometry, the manufacturer warranty is void, and you’re left paying for repairs out of pocket. In San Antonio, where summer heat and spring storms hit entry doors harder than most homeowners expect, this installation standard isn’t optional. It’s the product.
