Key Features
- Aerospace-grade 6063-T5 aluminum construction for strength and durability.
- EPDM sealing system along sill, sides, and between panels for full watertight protection.
- Modular 3-panel design — expand height by adding panels as needed.
- Permanent side channels allow quick, secure deployment when flooding is imminent.
- Clamp or bolt compression system ensures tight sealing under pressure.
- Stainless steel hardware resists corrosion and coastal conditions.
- Reusable and low-maintenance — rinse, dry, and store after each use.
- Designed, tested, and engineered for residential, multifamily and commercial buildings.
The WDS Door Flood Barrier Kit protects the openings where floodwater strikes first: building lobbies, egress doors, elevator vestibules, and waterfront home entrances. It is built for property managers, condo boards, and coastal homeowners who cannot afford water inside — FEMA estimates just 5 inches of water can cause over $25,000 in damage.
Permanent side channels mount discreetly to your existing frame. When heavy rain, a King Tide, or storm surge threatens, your staff stacks the numbered aluminum panels and compresses the EPDM gaskets in minutes — no tools, no sandbags. In stock now — we ship across the continental USA from North Miami, FL.
Marine-grade 6063-T5 aluminum with stainless-steel hardware, engineered for Florida's coastal humidity and repeated seasonal use. After each event, rinse, dry, and store — ready to protect for decades.
