Doral Architectural Impact Glazing, Pivot Doors & Hurricane Envelopes

Doral occupies an inland position in West-Central Miami-Dade County directly bordering the open Everglades buffer to the west. Under ASCE 7-22, Doral requires an engineered basic wind speed of 185 MPH. Because Doral features wide logistics avenues, extensive business parks, and low-roughness commercial corridors along NW 87th Avenue and NW 107th Avenue, wind currents operate primarily under Exposure C conditions. The absence of coastal high-rise friction allows cyclonic storm fronts and convective microbursts to travel inland with minimal deceleration. This produces high ground-level velocity pressures, severe turbulent buffeting, and rapid pressure reversals on residential facades in Modern Doral, Mansions at Doral, and Islands at Doral, where negative design pressures reach -135 PSF on upper building corners.

Impact fenestration systems for Doral luxury estates and commercial facilities are engineered to comply with Miami-Dade TAS 201, TAS 202, and TAS 203 testing standards. Units feature heavy-gauge extruded 6063-T6 aluminum frames with internal structural polyamide thermal breaks to optimize solar heat gain coefficients (SHGC) under Doral's intense inland heat. Glass build-ups incorporate 1-5/16 inch insulated laminated impact units with a 0.090-inch Kuraray SentryGlas ionoplast interlayer bonded between two lites of heat-strengthened glass. This configuration provides a design pressure capacity of +105 PSF positive and -135 PSF negative. The SentryGlas interlayer maintains rigidity under high-temperature solar loading, preventing interlayer creep or glass de-lamination while eliminating airborne projectile penetration from warehouse-area debris.

To meet the grand architectural scales of Modern Doral and custom estates, we construct 12ft monumental pivot entryways. The door frame is built around an internal aerospace-grade steel rectangular tube chassis, fully welded and stress-relieved to prevent panel warping across wide thermal differentials. The door operates on a concealed FritsJurgens System M+ hydraulic floor pivot, capable of supporting leaf weights up to 1,100 pounds with precision 90-degree hold-open, auto-closing, and adjustable hydraulic backcheck dampening. The threshold utilizes a low-profile anodized aluminum sub-sill with magnetic perimeter weatherstripping, engineered to resist 15 PSF water penetration test pressures. Anchor bolts consisting of 3/8-inch diameter 316 stainless steel wedge anchors are set into the structural concrete floor slab and header beam.

For Doral patio and lanai enclosures, we engineer multi-panel motorized sliding glass systems that open spans up to 40 feet wide. The door panels are fabricated with narrow 1-1/8 inch structural interlocking vertical stiles to maximize daylight while maintaining TAS 202 structural deflection compliance. The floor track is completely submerged into the finished floor level, utilizing an integrated 12 GPM extruded aluminum and stainless steel linear slot drain. During intense inland downpours common along the Everglades fringe, water draining from the exterior glass surface enters the slot drain and is directed into dual 2-inch PVC discharge pipes. Concealed digital motor operators feature obstacle detection, battery back-up systems, and smart home automation integration.

Doral's luxury multi-car garages and commercial delivery portals require reinforced Category 5 overhead doors. Our installations feature Miami-Dade NOA-certified 24-gauge exterior steel / 27-gauge interior steel sandwich panels with continuous 20-gauge galvanized steel U-bar horizontal reinforcement struts attached across each panel hinge line. Vertical tracks are constructed from 12-gauge commercial galvanized steel fastened to reinforced concrete jambs with Hilti HUS3-H concrete screw anchors at 10-inch intervals. The system includes 11-gauge heavy-duty steel hinge hardware, 2-inch solid steel precision ball-bearing rollers with nylon tires, and high-tension oil-tempered torsion springs calibrated for wind speeds up to 185 MPH.

Residential and commercial roofs in Doral face extreme UV degradation and severe convective storm turbulence. We install mechanically seamed standing seam roofing systems using 24-gauge Galvalume steel coated with high-performance Kynar 500 / PVDF resin finish. Panels are fabricated with 2-inch vertical ribs double-locked at 360 degrees along all seams, eliminating exposed fasteners. The panel hold-down system uses two-piece stainless steel expansion clips that accommodate thermal expansion over long panel runs while achieving -130 PSF uplift resistance. Substrate preparation includes high-temperature self-adhered polyolefin-surfaced bitumen underlayment direct to 5/8-inch APA-rated CDX plywood secured with ring-shank nails at 6-inch perimeter spacing.
