FAQ

Company and Product Origin

  • A: We are a global company with offices in the USA, Australia, South Korea, Hong Kong, and France. Our team is positioned worldwide to provide 24/7 customer support. We also have global operations, sending US products around the world.

  • A: For our US operation, all products are assembled in the USA using premium components from the USA, Germany, Australia, and South Korea.

     

    Key component manufacturing locations include:

    • AZON thermal break (frames) – Michigan, USA

    • Arkema Kynar finishes – Kentucky, USA

    • Vitro Glass – Pennsylvania, USA

    • Aluminum extrusions – South Korea

    • Hardware – Australia and Germany
       

    All parts are consolidated and shipped directly to our customers.

Certifications and Compliance

  • A: Yes, our systems are Florida Product Approved, including certifications for Miami-Dade County and the HVHZ (High Velocity Hurricane Zone) — meeting the most stringent standards required for hurricane-prone areas. Please consult with one of our design specialists to ensure you select the right system for your project.

  • A: Yes, we offer systems that comply with California Title 24 energy efficiency standards, with over 360 NFRC-certified configurations available.

  • A: Yes, our systems are NFRC certified, with more than 360 tested configurations for verified energy efficiency and thermal performance.

System Support and Track Details

  • A: We offer bottom-supported, top-hung, and dual supported (top & bottom) systems.

    • Most of our systems are bottom-supported, meaning the panels rest on a bottom track and place no additional load on your header — only your frame or roof load needs to be considered.

    • Freeway systems are top-hung, allowing for a clean threshold design. 

    The HD option offers adjustable weight distribution between top and bottom tracks, providing extra support for larger or heavier systems. 

  • A: Our HD (Heavy Duty) system is a dual-supported (top and bottom) roller configuration that offers smoother operation by distributing the panel weight — typically 70% on the bottom and 30% on the top, with adjustable ratios depending on installation needs. This option provides extra support for larger or heavier panels.

     

    We recommend the HD system in the following cases:

     

    • When panel width exceeds 38” and/or height exceeds 98”

    • When an egress door is attached to the last folding panel (not to a fixed jamb) and the panel exceeds 38” wide and/or 82” high

    • When using triple-pane laminated glass panels

    • When our team identifies structural need based on your CAD drawing review

  • A: We offer 7 bottom track types to suit different systems and site conditions:

     

    1. Standard Combo Bottom Track – For weather-exposed areas; can be surface-mounted or recessed

    2. Standard UPVC Bottom Track – Designed specifically for our UPVC systems

    3. Surface Mount Bottom Track – For protected areas where recessing isn’t feasible

    4. Minimal Recess Bottom Track – For protected areas with hardwood or tile flooring

    5. Freeway Bottom Track – Used with freeway swing door systems

    6. Automotive Bottom Track – Built to withstand vehicle traffic (drive-over rated)

    7. ClearView Bottom Track–  Specifically designed for our ClearView (frameless) systems

  • A: You can view detailed schematics here:

    Bottom Track Drawings (Google Drive)

    Our most popular track is the combo surface/recess mount model, offering weather resistance and flexible installation.

Panel Configuration and Stacking

  • A: The extension depends on your panel size. For example, if your door is 96" wide and you choose a 3-panel configuration, each panel would be approximately 32" wide. So when opened and stacked, they would extend out around 32 inches from the wall.

  • A: Each panel is approximately 2 inches thick when closed. When stacked, the total thickness depends on the number of panels in your configuration. For example, in a 98" wide system with 3 panels, the panels will stack to approximately 6 inches at the side, allowing you to fully open and utilize the entire opening with minimal obstruction.

  • A: In folding systems, a “panel” refers to one section of a folding door — not a door. So a “3-panel folding door” means one system made up of 3 folding panels, not 3 individual doors.
     

    Typically, the price does not change based on the number of panels. A 3-panel or 4-panel system with the same overall size (width × height) will cost the same.

    Exception:Freeway/HD configurations with integrated swing doors may be priced differently.

Weather Protection

  • A: Yes, we recommend the FoldA Aluminum 57-High Wind series specifically built for extreme weather, such as freezing climates and hurricane zones.

    It features;

    • AZON thermal barriers, the strongest thermal barrier available - link (AZON)

    • Compliance with Florida and International Building Codes

    • Triple-pane Low-E Argon glass for enhanced energy performance

    Optional foam-filled frames for added insulation

  • A: Our systems are equipped with storm-rated weather seals that protect all outer edges and tightly seal between each panel using a patented interlocking double seal system. Our patented finger-safe seal design is the safest in the industry, great for families!

  • A: Like all folding or sliding systems with bottom tracks, there is a chance that sand or debris can accumulate.
     

    To manage this:
     

    • Weep holes should be installed along the outer edge of the bottom track to allow proper drainage of sand and water.

    • These weep holes are not pre-drilled and should be custom-installed on-site by your contractor based on your site conditions (e.g., recessed concrete, trim, or decking).

    • In cases where the track is recessed into concrete, weep holes may need to be installed higher for proper drainage.

    • Our systems also feature outer edge panel seals that help prevent debris from entering the track in the first place.

Thermal Break

  • A: While both systems appear similar, the FoldA Aluminum 57 features a built-in thermal break in the frame, offering enhanced energy efficiency. This thermal barrier reduces heat and cold transfer and minimizes condensation – making it a better choice for challenging climates or energy-conscious projects.

  • A: AZON is a high-performance thermal barrier used in aluminum frames. It is widely recognized as the strongest thermal break available for commercial systems like curtain walls and storefronts.

  • A:

    • Forms a true non-metal-to-metal barrier, reducing heat transfer and condensation.

    • Offers superior impact resistance, shear strength, and heat distortion resistance

    • Meets the strict standards of the High Velocity Hurricane Zone (HVHZ) under both the International Building Code and Florida Building Code.

    Helps achieve lower U-Factors and SHGC values for better energy efficiency.

    See below:


    1/.  404.2.5 Thresholds.

    Thresholds, if provided at doorways, shall be 1/2 inch (13 mm) high maximum. Raised thresholds and changes in level at doorways shall comply with 302 and 303.


    Thresholds at Doorways. The 1991 Standards, at section 4.13.8, require the height of thresholds at doorways not to exceed 1/2 inch and thresholds at exterior sliding doors not to exceed 3/4 inch. Sections 404.1 and 404.2.5 of the 2010 Standards require the height of thresholds at all doorways that are part of an accessible route not to exceed 1/2 inch. The 1991 Standards and the 2010 Standards require raised thresholds that exceed ¼ inch in height to be beveled on each side with a slope not steeper than 1:2. The 2010 Standards include an exception that exempts existing and altered thresholds that do not exceed 3/4 inch in height and are beveled on each side from the requirement.


    EXCEPTION: Existing or altered thresholds 3/4 inch (19 mm) high maximum that have a beveled edge on each side with a slope not steeper than 1:2 shall not be required to comply with 404.2.5.


    2/. 404.2.3 Clear Width.

    Door openings shall provide a clear width of 32 inches (815 mm) minimum. Clear openings of doorways with swinging doors shall be measured between the face of the door and the stop, with the door open 90 degrees. Openings more than 24 inches (610 mm) deep shall provide a clear opening of 36 inches (915 mm) minimum. There shall be no projections into the required clear opening width lower than 34 inches (865 mm) above the finish floor or ground. Projections into the clear opening width between 34 inches (865 mm) and 80 inches (2030 mm) above the finish floor or ground shall not exceed 4 inches (100 mm).


    EXCEPTIONS:

    1. In alterations, a projection of 5/8 inch (16 mm) maximum into the required clear width shall be permitted for the latch side stop.

    2. Door closers and door stops shall be permitted to be 78 inches (1980 mm) minimum above the finish floor or ground.


    3/.  404.2.7 Door and Gate Hardware.

    Handles, pulls, latches, locks, and other operable parts on doors and gates shall comply with 309.4. Operable parts of such hardware shall be 34 inches (865 mm) minimum and 48 inches (1220 mm) maximum above the finish floor or ground. Where sliding doors are in the fully open position, operating hardware shall be exposed and usable from both sides.


    EXCEPTIONS:

    1. Existing locks shall be permitted in any location at existing glazed doors without stiles, existing overhead rolling doors or grilles, and similar existing doors or grilles that are designed with locks that are activated only at the top or bottom rail.

    2. Access gates in barrier walls and fences protecting pools, spas, and hot tubs shall be permitted to have operable parts of the release of latch on self-latching devices at 54 inches (1370 mm) maximum above the finish floor or ground provided the self-latching devices are not also self-locking devices and operated by means of a key, electronic opener, or integral combination lock.


    Advisory 404.2.7 Door and Gate Hardware. Door hardware that can be operated with a closed fist or a loose grip accommodates the greatest range of users. Hardware that requires simultaneous hand and finger movements require greater dexterity and coordination, and is not recommended.


    4/.  404.2.9 Door and Gate Opening Force.

    Fire doors shall have a minimum opening force allowable by the appropriate administrative authority. The force for pushing or pulling open a door or gate other than fire doors shall be as follows:

    1. Interior hinged doors and gates: 5 pounds (22.2 N) maximum.

    2. Sliding or folding doors: 5 pounds (22.2 N) maximum.


    These forces do not apply to the force required to retract latch bolts or disengage other devices that hold the door or gate in a closed position.

    Advisory 404.2.9 Door and Gate Opening Force. The maximum force pertains to the continuous application of force necessary to fully open a door, not the initial force needed to overcome the inertia of the door. It does not apply to the force required to retract bolts or to disengage other devices used to keep the door in a closed position.


    5/.  404.2.10 Door and Gate Surfaces.

    Swinging door and gate surfaces within 10 inches (255 mm) of the finish floor or ground measured vertically shall have a smooth surface on the push side extending the full width of the door or gate.

Installation and Setup

  • A: Please fill out our quick Installer Request Form here : Find an Installer

    We’ll connect you with a qualified local installer in your area.

  • A:

    • Height: Measure from the bottom of your header beam to the top of the finished floor. Take this measurement in 3 places; left side, right side, and center. Use the shortest measurement as your starting point for the next step. Then subtract 1" for leveling and add 1.5" if you plan to recess the bottom track.

    • Width: Measure from left to right trimmer stud. Take this measurement from the top of the trimmer stud and the bottom. Use the shortest measurement as your starting point for the next step. Subtract 1" to allow for adjustment during installation.

  • A: Your rough opening should be 1 inch larger in both height and width than the door system ordered.

    Example:

    • Ordered system: 143" W × 79" H

    • Rough opening: 144" W × 80" H

  • A: Our systems are designed for simple and efficient installation, making them among the easiest in the industry. A typical 16' × 8' multi-fold system can be installed in under 4 hours by a crew of 3 — assuming the rough opening is correctly prepared, with no additional concrete, framing, or finish work required.

  • A: Always consult a licensed structural engineer, architect, or licensed or contractor to ensure compliance with local codes. Here are some general guidelines:
     

    • Maximum header deflection should not exceed L/720 of the span or ¼", whichever is less.

    • Most of our systems are bottom-supported, so no significant load is transferred to the top header.

    • The top track functions as a guide rail and allows for vertical movement in case of deflection.

    • Panel weight is approximately 5.5 lbs/ft² (2.5 kg) of door surface area for an aluminum unit with dual-pane glass.

Warranty Support

  • A: We’re here to help. All warranty or service issues are handled through our authorized support center.

    If a component needs replacement, our team may travel to the installation site to ensure proper support and customer satisfaction.
