Product Overview - VLX 100 Double Swing / French Door
French doors carry a specific architectural promise: equal panels, balanced proportions, and a sense of openness that sliding doors rarely match. The VLX 100 delivers on that promise through a modern aluminum platform that sheds the weight and rot susceptibility of traditional wood construction.
The design centers on paired active panels, each hung on concealed hinges that preserve clean vertical lines. Sightlines stay symmetrical whether the doors are closed or swung open to 90 degrees. The flush threshold eliminates the trip hazard common to older French door systems, a detail that matters for families with young children or anyone aging in place in their Margate home. Multi-point lock hardware engages at three locations along the jamb, not just at the handle, which distributes closing pressure evenly and prevents the panel warp that single-point locks eventually cause.
Architecturally, the VLX 100 fits transitional and contemporary homes most naturally, though we’ve installed it in renovated Florida ranch homes where homeowners wanted to brighten dark central living spaces. The 2.56″ profile width reads as substantial without appearing industrial. Aluminum construction resists the salt air and humidity that degrades wood and steel in coastal Broward County. For Margate properties within reach of storm surge zones, the impact-resistant laminated glass option brings the system up to current wind-load requirements without adding visible storm bars or shutters.

AfterPerformance Features
Thermal Efficiency
The VLX 100 uses a thermal break that separates interior and exterior aluminum surfaces, cutting conductive heat transfer. NFRC-rated performance numbers let you compare annual energy costs directly against other door systems. In Margate’s cooling-dominated climate, this matters more than heating performance. Pair the thermal break with Low-E glass and you reduce solar heat gain through the opening without darkening the view.
Acoustic Performance
Multi-chamber frame construction and dual weatherstrip compression zones dampen exterior noise. The laminated glass option adds mass and a viscous interlayer that absorbs sound energy, particularly effective against low-frequency traffic rumble from nearby Atlantic Boulevard or Sample Road corridors.
Airtightness & Weather Seal
Continuous bulb-and-blade weatherstripping runs the full perimeter of each active panel. When the multi-point lock draws the panel home, compression is uniform top to bottom. AAMA 2400 testing verifies that the assembly holds its seal through repeated cycling and temperature swings.
Waterproofing
The sill profile includes a dam and weep system that redirects wind-driven rain to the exterior. During installation, our crews apply AAMA 812 low-expansion foam to all perimeter joints, creating a secondary moisture barrier between frame and rough opening. We test every installation with a calibrated water spray before we leave the job site.
Wind Resistance
Standard aluminum construction with reinforced corner keys meets local wind-load requirements for inland Broward County. The laminated glass upgrade brings the assembly into compliance for higher-velocity hurricane zones without visible reinforcement. Every installation we complete in Margate is documented for permit and inspection records.
Security & Hardware
Multi-point locking engages at the handle, midpoint, and floor-level shoot bolt. The hardware is factory-matched to the frame finish. Hinges are concealed and tamper-resistant. For ground-floor installations or rear patio doors in Margate’s single-family neighborhoods, this three-point system exceeds the security of most standard entry door setups.
Color & Glass Options

Six finishes cover most architectural directions we see in Margate. Premium Black and Anodized Silver suit contemporary homes with clean trim packages and large overhangs. Pure White remains the default for traditional Florida homes with lighter exterior palettes. Bronze and Champagne warm up stucco and stone facades without the high contrast of black. Teak Wood finish gives you the grain appearance of wood without the maintenance cycle of staining and sealing that actual teak demands in South Florida humidity.
Glass selection depends on the room function and exposure. Clear glass maximizes views for lake-facing or garden-oriented openings. Frosted and Obscure options provide privacy for bathrooms or bedroom exits that open onto shared outdoor space. Low-E coating is standard recommendation for west-facing walls that take afternoon sun. Tempered glass meets safety code for doors and sidelights. Laminated glass serves double duty: impact resistance for hurricane protection plus the acoustic benefits of the inner layer.
The retractable screen option stores in a housing at the jamb when not in use, preserving the clean sightlines that make French doors appealing. For openings where insects aren’t a persistent issue, skipping the screen saves cost and eliminates one moving part.
Installation by Sightline Windows & Doors Margate in Margate
Factory warranty coverage on the VLX 100 requires installation by an authorized partner. Sightline Windows & Doors Margate holds that authorization, and our process is built to protect your investment from day one.
We start with a pre-install inspection of the rough opening: squareness, level, and structural integrity. In Margate’s active market, we see everything from original 1960s block construction to recent additions with engineered lumber. Each substrate demands different fastening patterns and flashing details. We adjust our approach rather than force a uniform method.
Setting the frame demands constant checking for level, plumb, and square. A French door pair that is even 1/8″ out of square will bind, leak, or stress the hinges within two seasons of Florida’s expansion and contraction cycles. We shim at structural points, never relying on foam to correct framing errors.
Perimeter sealing follows AAMA 812 standards with low-expansion foam that fills gaps without distorting the frame. Backer rod and sealant complete the exterior face. Our crews pull permits where required by Margate building codes and coordinate inspections for impact-rated installations.
Final steps include operational testing of both panels, lock engagement verification, and a water spray test that simulates wind-driven rain. We clean the work area and walk you through the hardware operation before we leave. Improper installation voids the manufacturer warranty, which is why we document every step with photos for your records and ours.
Margate’s position inland from the coast still exposes homes to significant wind events and near-constant humidity. Our installation accounts for both: positive drainage at the sill, corrosion-resistant fasteners, and sealant compatibility with local temperature ranges.
