Product Overview – VLX 500 Single & Double Hung Window

The VLX 500 is a classic hung window, the kind you’ll find on homes across Dallas from Oak Cliff to Richardson. It operates on a vertical track: the bottom sash slides up, the top sash slides down, or both move for balanced airflow. The single hung version has a fixed top sash and an operable bottom sash. The double hung lets you open either sash, which is genuinely useful on a mild spring evening when you want air moving at both the floor and ceiling level.

What separates this window from older aluminum frames is how it’s put together. The profile width measures 2.36 inches, which gives the frame enough structural depth to resist racking and warping, while staying slim enough to preserve glass area. The wall thickness runs 0.079 inches, which is a meaningful number in aluminum extrusions. It translates to a frame that feels solid when you close it, doesn’t flex under wind load, and keeps its square over time.

The tilt-in sash mechanism is what most buyers comment on first. Both sashes release inward with a simple latch at the top, letting you clean both surfaces of the glass from inside the house. For a two-story home in Dallas, that eliminates one genuinely annoying chore: hauling an extension ladder around the exterior to reach second-floor windows. We hear this constantly from homeowners in Preston Hollow and North Dallas who’ve lived with older windows that tilt, jam, or don’t tilt at all.

Aluminum as a frame material makes sense in North Texas. It doesn’t rot, it doesn’t attract termites, and it doesn’t swell or shrink with humidity swings. The VLX 500 uses a thermal break within the frame profile, which interrupts the direct metal-to-metal path that makes old aluminum windows sweat and feel hot to the touch in August. That detail matters in Dallas, where a west-facing window can sit in direct sun for six hours a day.

Technical Specifications

Here are the numbers and options that define the VLX 500. These specs come from the product line, and Westlight Windows Dallas can walk you through what each one means for a specific opening in your home.

• Wall thickness: 0.079 inches, which gives the frame its rigidity and resistance to bending under load.
• Profile width: 2.36 inches, balancing a slim look with the structural depth required for thermal-break performance.
• Available glass: Clear, Frosted, Low-E, Tempered, Laminated. Each glass type changes the window’s energy performance, privacy level, or impact resistance.
• Frame finishes: Premium Black, Pure White, Anodized Silver, Bronze, Champagne, and Teak Wood. All six are available on the VLX 500 for both single and double hung configurations.
• Screen options: Half-screen covers the lower sash opening; full-screen covers the entire window opening.
• Sash operation: Single hung (bottom sash operable) or double hung (both sashes operable), both with tilt-in cleaning.
• Performance standard compliance: NFRC-rated energy performance, AAMA 2400/2410 installation compliance, AAMA 812 low-expansion foam perimeter sealant.

Performance Features

Thermal Efficiency – The VLX 500 uses thermal break technology in the frame, which separates the interior and exterior aluminum surfaces. This breaks the conductivity path that makes traditional aluminum frames radiate heat. When paired with Low-E glass, the window earns an NFRC energy performance rating that reflects real savings during Dallas summers and the occasional hard freeze.

Acoustic Performance – Aluminum frames are dense, and density helps with sound control. The VLX 500 reduces exterior noise noticeably when compared to older, single-pane windows. For homeowners near major corridors like Central Expressway, Turtle Creek Boulevard, or rail lines, pairing this frame with laminated glass delivers a measurable drop in road and train noise inside the house.

Airtightness & Weather Seal – Drafty windows are usually a seal problem, not a glass problem. The VLX 500 uses a continuous perimeter weather seal that compresses when the sash closes. That reduces air infiltration, which means your HVAC system isn’t fighting outside air. It also cuts down on dust intrusion, which we hear about from Dallas homeowners during high-pollen months and West Texas dust events.

Waterproofing – The frame’s internal weep system is designed to channel water that enters the sill track back to the exterior, not into the wall cavity. That internal drainage geometry is part of the aluminum extrusion itself, not a secondary afterthought. It works with the perimeter installation seal to keep bulk water out during heavy Dallas thunderstorms.

Wind Resistance – North Texas sits on the edge of Tornado Alley, and spring storm seasons bring straight-line winds that punish weak window frames. The VLX 500 is wind-load rated for local climate requirements, and the 0.079-inch wall thickness means the frame doesn’t twist or bow when a line of thunderstorms pushes through. That structural integrity keeps the sashes sealing correctly under pressure.

Security & Hardware – The locking hardware on the VLX 500 engages at multiple points along the meeting rail where the sashes overlap. That’s a step up from a single thumbscrew latch. For homeowners focused on security, the optional laminated glass layer adds meaningful resistance to forced entry, holding the pane together even when struck.

Color & Glass Options

The VLX 500 comes in six finishes that cover most architectural styles in Dallas. Premium Black reads as contemporary and pairs well with dark-painted brick or stucco on newer builds in East Dallas or West Plano. Pure White is the safe, classic choice for traditional two-story brick homes throughout the metro. Anodized Silver has a raw-metal, mid-century quality that suits the original windows on 1950s and 1960s homes, while Bronze gives a warm, stately look that works on French eclectic or Tudor-style houses in places like Highland Park. Champagne is lighter than Bronze with a subtle metallic warmth. Teak Wood offers a wood-grain look on an aluminum substrate, giving you the appearance of wood without the maintenance schedule.

On glass, Clear is the baseline. Frosted works in bathrooms, side yards, or anywhere you want privacy without blinds. Low-E is the energy-performing workhorse, reflecting heat while letting light through, and it’s what we recommend most often in Dallas. Tempered glass breaks into small, rounded fragments and is required by code in certain locations like doors and adjacent sidelights. Laminated glass adds impact resistance and noise reduction, a strong pick for homes near highways or in areas with tighter storm-resistance expectations.

Installation by Westlight Windows Dallas in Dallas

Windows fail at the installation seam more often than the frame itself. That’s the honest truth, and it’s why we don’t shortcut the process. Westlight Windows Dallas installs the VLX 500 per the AAMA 2400/2410 installation standard, which governs how windows should be set, flashed, and sealed in residential construction. We also use AAMA 812 low-expansion foam sealant around every perimeter joint, which prevents air leaks without bowing the frame.

Our process starts with a pre-install inspection of the rough opening. We check the framing for rot, squareness, and moisture before anything goes in. Then we set the window level, plumb, and square. That step gets skipped by a lot of installers, and it’s the difference between a sash that glides smoothly and one that binds in the track after two years. The perimeter gets sealed with the AAMA 812 foam, followed by a waterproofing check, a final water test on the sill, and a full cleanup. We don’t leave old windows, packaging, or sealant smears behind.

Improper installation voids the manufacturer’s warranty. That’s not a scare tactic; it’s how warranty terms are written across the window industry. ViewLux covers the product, but the installation has to meet their standards. As an authorized partner, we’re trained on those standards, and our work keeps your warranty intact.

Dallas-specific conditions matter here. Our freeze-thaw cycles, hail exposure, and intense UV put real stress on exterior penetrations. The AAMA 812 foam performs in those conditions without cracking or shrinking the way old butyl tape does. We’ve salvaged projects where a previous window was installed with caulk-only perimeter sealing and failed within a season. The sealant spec is not a place to save twenty dollars.
