BEAUTIFULLY CRAFTED FOR THE UNIQUE ARCHITECTURE AND EXTREME CONDITIONS OF THE SOUTHEASTERN COASTAL US AND BEYOND, INVINCIA® DOORS ARE PRECISION ENGINEERED TO MEET AND EXCEED LOCAL CODE REQUIREMENTS.
Manufactured in our state-of-the-art facility using innovative technology, Invincia® doors are built to exacting tolerances. Every component is carefully engineered and assembled with precision, resulting in a product that is as impressive structurally as it is visually. The difference is evident not only in the finished aesthetic, but also in the rigorous testing process—where inferior products are literally torn apart under extreme conditions. Invincia® stands apart as a benchmark in performance-driven design for luxury custom wood doors.
Engineered for Extreme Performance
Tested to a design pressure (DP) of +/- 65, Invincia® doors meet and exceed the standards required for wood entry door systems along Florida’s Emerald Coast. These specifications are critical in regions exposed to high winds and severe weather events. Each door system is evaluated through a comprehensive testing protocol that simulates the forces of a hurricane, ensuring long-term reliability and protection.
The testing process includes evaluation for air and water infiltration, followed by a series of high-impact missile tests. Each door is subjected to three large missile impacts using 9-pound 2x4s traveling at 34 MPH. After impact testing, the system must endure 9,000 positive and negative pressure cycles, simulating repeated stress conditions over time. Failure at any stage results in a failed test, underscoring the strict standards each door must meet.
For homeowners, this means confidence. Invincia® impact-rated doors are built and tested to ensure your investment is not only visually striking but also structurally secure against the elements.
Custom Craftsmanship Without Limits
Unlike mass-produced alternatives, Invincia® doors are not limited to a fixed catalog of styles. Each door is fully custom built to your specifications, allowing for complete creative freedom in design, proportions, wood selection, and detailing. This approach ensures that every door is a unique reflection of the home it belongs to.
As a result, no two Invincia® doors are exactly alike. Whether your vision leans toward classic elegance, modern simplicity, or something entirely bespoke, our team works closely with you to bring that vision to life. Every door becomes a personal statement piece—an architectural focal point that enhances curb appeal while delivering uncompromising performance.
These custom wood doors are designed to integrate seamlessly with a wide range of architectural styles, from coastal residences inspired by coastal architecture to contemporary and transitional homes. The flexibility in design ensures that your door not only meets structural requirements but also complements the overall aesthetic of your property.
Where Beauty Meets Protection
Invincia® doors embody the balance between craftsmanship and engineering. Each door is meticulously constructed to withstand harsh environmental conditions while maintaining the warmth and character of natural wood. The result is a product that delivers both durability and timeless beauty.
From the selection of premium materials to the final finishing details, every step of the process is guided by a commitment to excellence. Advanced manufacturing techniques ensure consistency and precision, while traditional woodworking expertise preserves the authenticity and richness that define high-end custom doors.
These impact-rated doors are ideal for homeowners seeking both security and sophistication. Whether used as grand entry doors or integrated into a larger architectural system, Invincia® products elevate the overall design while providing reliable protection.
A Personal Work of Art
With Invincia® doors, your entryway becomes more than just an access point—it becomes a defining feature of your home. Each door is crafted to welcome family and guests with distinction while standing strong against the forces of nature. It is both a functional barrier and a carefully designed expression of personal style.
Because every project is custom, the possibilities are nearly limitless. From unique panel configurations and glass inserts to custom finishes and proportions, each detail is tailored to your exact preferences. The result is a door that is not only built to perform, but also designed to inspire.

Frequently Asked Questions
See below to learn more about our ceilings, paneling, and decking products.
E.F. San Juan combines in-house custom woodworking with tested, performance-driven door engineering and five decades of experience in Florida and Southeastern coastal environments. That combination is especially valuable when the entry must serve as both a defining architectural feature and a carefully coordinated protective assembly. The team can also align the door with adjacent mouldings, paneling, cabinetry, and other millwork for a more cohesive result.
Useful information includes architectural drawings, rough-opening dimensions, elevations, project location, required design pressures, door operation, panel and glass design, wood species, finish, hardware, access-control needs, installation scope, and requested delivery date. Pricing and lead time vary with engineering, approvals, materials, custom detailing, glazing, hardware availability, finish sampling, production workload, freight, and site conditions; an early budget should therefore be treated as preliminary until the system is defined.
Depending on the project and contracted scope, E.F. San Juan can assist with design development, technical coordination, shop drawings, material and finish selection, fabrication, glazing and hardware coordination, finishing, delivery, installation, and service. Responsibilities for structural design, field dimensions, rough-opening preparation, waterproofing, electrical access control, approvals, and inspections should be assigned clearly among the architect, engineer, builder, specialty trades, and E.F. San Juan.
Successful coastal performance depends on the complete design and care of the opening: wood species, construction, moisture preparation, finish system, glazing and panel details, overhang and exposure, drainage, hardware, installation, and maintenance. No exterior wood door should be treated as maintenance-free. E.F. San Juan can recommend project-appropriate materials and finishing approaches, while the final maintenance plan and warranty obligations should be confirmed for the selected assembly and site conditions.
Invincia is intended for projects where architectural customization and impact performance must be developed together. E.F. San Juan can shape the door’s proportions, species, panels, details, glazing, finish, and relationship to surrounding millwork rather than selecting only from standard styles. When comparing alternatives, clients should also examine the frame, hardware, testing, approval, finish, installation, service, and included scope—not simply the door’s appearance or initial price.
Potentially, depending on the exact assembly and available approval. Entry pairs, sidelights, transoms, arched heads, and other special configurations introduce additional requirements for frames, mullions, glass, hardware, anchorage, and structural support. E.F. San Juan should review the complete opening early and confirm which tested configuration can achieve the desired composition before the surrounding structure and waterproofing are finalized.
Invincia doors can be tailored in architectural style, proportions, panel layout, wood species, moulded details, glazing, finish, and hardware to complement traditional, transitional, coastal, or contemporary architecture. The available choices depend on the tested system and project requirements, so E.F. San Juan evaluates custom details against approved dimensions, construction, glass, frame, hardware, and anchorage rather than assuming every visual concept can be substituted freely.
No. A published design-pressure test does not establish universal suitability for every site or door configuration. Required pressures depend on location, building height, exposure, opening position, building geometry, and applicable code; approvals can also differ inside and outside Florida’s High-Velocity Hurricane Zone. The project’s licensed design professional and local authority having jurisdiction must verify that the proposed Invincia configuration meets the requirements for the specific opening.
E.F. San Juan’s Invincia® door systems have been tested to a design pressure of +/- 65. The testing sequence includes air and water infiltration, three large-missile impacts using nine-pound 2x4s traveling at 34 miles per hour, and 9,000 positive and negative pressure cycles after impact. The exact approved size, configuration, components, and limits of use should still be confirmed for each specified door system.
Invincia® is E.F. San Juan’s custom impact-rated wood door system, developed to combine the warmth and design flexibility of a finely crafted entry door with tested performance for demanding coastal conditions. Unlike a fixed catalog door, an Invincia system is designed around the architecture of the project while remaining subject to the dimensions, components, and installation requirements covered by its applicable testing and approval documentation.
