YellowFIN™ Direct-Mount Flood Barrier System

Clean Aesthetic • Structural Strength • American-Made Protection

YellowFIN™ is an advanced direct-mount flood panel system engineered for openings where appearance, structural performance and rapid deployment are equally important.

Designed to mount directly to doorways, windows, garages and wall openings, YellowFIN™ eliminates the need for permanently installed vertical posts while providing strong resistance against hydrostatic and hydrodynamic pressures, debris and impact loads associated with severe weather.

This patent-pending flood protection system combines a clean architectural appearance with rugged, industrial-level performance, making it suitable for residential, commercial and infrastructure applications.

Direct-Mount Installation System

YellowFIN™ flood panels and their aluminium frame system install directly into masonry, concrete or CMU walls, eliminating the need for surface-mounted posts.

How YellowFIN™ Flood Panels Work

• 316L marine-grade stainless steel precision anchors secure the panel to the wall, sill and ground.
• Multi-layer composite panels are positioned and secured using turn-bolt fasteners, with latch-lock gaskets on the rear of the panels providing a tight seal.
• Tightening the turn bolts compresses the HDPE seals between panels, against the rear surface and along the underside to create a watertight seal.
• The panels are secured to both the wall and floor, creating a continuous seal that helps prevent water ingress around joints and edges.
• The dual-attachment design provides structural stability under hydrostatic pressure and creates a reliable barrier for doors, windows, openings, sills, garages and low walls.
• The result is a secure flood barrier with minimal permanent hardware and no permanent visible vertical posts.

Why Choose YellowFIN™ Flood Panels?

• Modular & Configurable
  Standard and custom panel sizes, filler pieces, corner extrusions and a durable latch-lock system allow protection to be configured for a wide range of areas and layouts.
• Durable & Reusable
  The panels are engineered for repeated use and can be cleaned, stored and redeployed as required.
• 100% USA-Made
  Composite panels, metal extrusions, seals and hardware are manufactured in the United States, with fabrication completed in Pompano Beach, Florida.
• Architectural Appearance
  The flood panels mount directly to the structure for a clean, smooth appearance. No vertical posts are required, while receiver holes can be concealed with optional decorative caps.
• High Structural Rigidity
  Fiberglass-reinforced, multi-layer honeycomb composite panels are framed with durable aluminium extrusions designed to resist flexure under load.
• Impact Resistant
  The panels and industrial-grade 6063-T6 aluminium frames are designed to withstand heavy debris impact without cracking or deformation.

Engineered Panel Construction

YellowFIN™ flood panels feature a fiberglass-reinforced, multi-layer composite construction with a honeycomb core designed to provide an excellent stiffness-to-weight ratio. Each panel uses a sealed aluminium framing method to create a rigid perimeter that distributes hydrostatic pressure and helps minimise panel deflection.

The U-shaped aluminium framing reinforces the complete panel edge, increasing structural strength and long-term durability while helping prevent bowing under pressure.

Important: Confirm that the structure can withstand the hydrostatic pressure associated with flooding and applicable dry floodproofing requirements. Consult a local Professional Engineer where appropriate.

Deployment & Storage

• Panels are lightweight and manageable by 1–2 people.
• YellowFIN™ panels store flat and can be stacked, helping simplify deployment and storage.
• Flood panels can be cleaned using standard cleaning materials.
• The system is designed for repeated installations and use without degradation.
• Panels and aluminium framing are designed not to warp, rot, crack or delaminate, including in tropical conditions.

Flood Panel Mounting

YellowFIN™ panels are typically mounted outside the protected opening and bolted to the perimeter jamb of the door, window or garage using star-shaped turn knobs.

The bottom aluminium footer extrusion extends away from the opening and is secured to the ground or sill below.

The integrated latch-lock mechanism and HDPE gaskets on the sides, rear and underside of the panels create a watertight sealing system.

Where obstructions such as door handles, air-conditioning units or other protrusions are present, U-shaped or box-shaped panel configurations can be used to clear the obstruction. Spacer extrusions can also position the panel further away from the wall where required.

Kicker support legs can be added to longer flood barrier spans to provide additional hydrostatic and hydrodynamic resistance.

Advanced Sealing System

YellowFIN™ uses an integrated sealing strategy designed to provide reliable performance under flood conditions.

• Bottom Seal:
  ½" thick compression seal attached to a dedicated base extrusion that sits firmly against the ground.
• Back Seals:
  ½" thick compression seals engage directly with the wall surface.
• Inter-Panel Connector Seals:
  ½" thick compression seals allow adjacent panels to seal together once the latch-lock connectors are engaged.

This sealing configuration is designed to maintain consistent sealing performance under sustained hydrostatic pressure.

Modular Configuration Offers Layout Flexibility

YellowFIN™ flood panels can extend beyond single-door protection and can be configured for windows, double doors, sliding doors, garage openings, vents, hallways, elevator doors and other vulnerable openings.

• Connection Latches: Join multiple panels into longer runs while sealing adjacent panels together.
• 90-Degree Corner Extrusions: Allow L-shaped, U-shaped and more complex perimeter configurations.
• Spacers: Position panels away from the wall to clear sills, door handles and other obstructions.
• Foot Extrusions: Can be positioned sideways for inside-threshold mounting.

From a single service door to larger infrastructure openings, YellowFIN™ can be configured to suit site requirements and customised for specific applications.

Simple Installation & Set-Up

1. Align Panels and Mark Wall Mount Holes

• Position the YellowFIN panels against the wall in front of the opening so the panel overlaps the sides of the opening and sits firmly against the wall.
• Use the pre-drilled holes in the aluminium frame to mark the mounting-hole locations on the wall.
• Remove the panel.
• Drill the wall mounting holes 1/8" lower than the marked location so the panel is correctly positioned when the bottom bolts are secured.
• Thoroughly clean the drilled holes before inserting the anchor bolts.
• Insert and lock the drop-in anchor bolts. Epoxy may be used to reinforce the drop-in receiver where appropriate.

2. Mark and Drill Ground Mount Holes

• Place the panel firmly against the wall and press downward to compress the footer seal against the ground. Pressing on the aluminium footer lip can help maintain pressure.
• Insert the wall turn bolts through the panel and into the receivers.
• Tighten the bolts until the panel is firmly attached to the wall.
• Mark the ground-mount hole locations.
• Remove the panel and drill the ground mounting holes at the marked locations.
• Thoroughly clean the drilled holes before inserting the ground anchor bolts.
• Insert and lock the drop-in anchor bolts into the ground.

3. Install and Tighten YellowFIN™ Panels

• Alternate between the ground bolts and turn bolts, tightening them in a staggered rotation. Do not fully tighten one bolt to maximum torque immediately.
• Use the included Allen wrench to tighten the M12 bolts through the bottom foot aluminium extrusion and into the ground receiver anchors.
• Manually twist the turn bolts to tighten them into the wall receiver anchors.
• Continue tightening until the panel seals are fully pressurised against both the wall and ground.

Custom Panel Colours and Printed Graphics Available

YellowFIN™ fiberglass composite panels can be customised to complement the colour of a wall, building, door or entryway. Custom images, logos, graphics and signage can also be applied to the FRP panels for advertising, branding or visual integration.
