Every opening is impact-rated. Every connection is engineered from foundation to roof ridge. A Lumee home is built as one continuous steel system designed for 150+ mph winds — no single feature does it alone, the whole structure works together.
Every opening in a Lumee home is impact-rated. This is not an upgrade or an option — it is what ships in the kit. It is the feature set that drives the insurance savings and the peace-of-mind story.
The most stringent protocol in the U.S. — a 9-lb 2×4 launched at 34 mph, then 9,000 cycles of positive and negative pressure.
When an opening fails, the building pressurises internally and the pressure pushes the roof off from inside. Sealed openings keep the envelope intact — the single most important factor in surviving a hurricane.
NOA (Notice of Acceptance) is Miami-Dade's product-approval system for hurricane-zone materials. Every Lumee component that requires it carries it.
A Lumee home is not just strong at any one point. It is connected from foundation anchor bolt to roof ridge as one continuous steel structure. Every connection is engineered and hardware-attached, not nailed.
Anchor bolts embedded in the foundation connect to the steel wall-panel base track.
Steel panels are bolted and screwed together at every stud location.
Simpson Strong-Tie hurricane straps at every truss-to-wall connection. Not clips — full wrap straps rated for the highest wind category on the FL mitigation form.
A 5:12 hip roof with 12-inch overhangs on all four sides. The hip shape is aerodynamically superior to a gable in hurricane winds; 12-inch overhangs minimise uplift (overhangs beyond 20 inches significantly increase uplift risk) while still protecting the wall cladding from rain.
The steel frame, hip roof, continuous load path and impact openings work together as one system. Two pieces anchor it: a safe room at the centre of the home, and a whole-structure wind rating.
Every Lumee home includes a FEMA-rated safe room. The kitchen pantry of every model doubles as the safe room — built with heavy-gauge steel panels and a rated door, located at the centre of the plan away from exterior walls. It is designed to protect occupants during a direct tornado or extreme hurricane event.
| Factor | Cold-formed steel (Lumee) | Wood frame (traditional) |
|---|---|---|
| Wind resistance | 150+ mph engineered. Steel does not split, crack or splinter under wind loads. | Varies. Wood connections rely on nails that can pull through under sustained pressure. |
| Fire | Non-combustible. Steel does not burn. | Combustible. The primary structural fuel in a house fire. |
| Termites / pests | Immune. Steel is inedible. | $5B+ annual damage in the U.S.; the Gulf Coast is the highest-risk zone. |
| Mold / rot | Steel does not absorb moisture or support mold growth. | Wood absorbs moisture. Post-hurricane flooding creates rot and mold inside walls. |
| Dimensional stability | Steel does not warp, bow, twist or shrink. Walls stay plumb. | Lumber shrinks, warps and twists as it dries, causing drywall cracks and door misalignment. |
| Insurance | $3K–$7K/year savings via wind mitigation credits + construction-type rating. | Full premium. No construction-type credit. Higher claims history. |
Every Lumee home is designed for full solar and battery operation. This is not an upgrade — the infrastructure is built into every floor plan.
Pre-routed solar and battery conduit inside the walls during factory assembly. No retrofit wiring needed.
Reserved panel space for the solar inverter and battery management system.
A designated equipment area on every floor plan for battery storage — FranklinWH, Tesla, or equivalent.
Bosch high-efficiency heat pump HVAC minimises energy draw, maximising battery runtime during outages.
Rheem Proterra hybrid hot water tank uses heat-pump technology at 3.5× the efficiency of a standard electric tank.
When the grid goes down for weeks after a hurricane, a Lumee home with solar and battery keeps the refrigerator running, the HVAC operating, ceiling fans on, and water pumps active for elevated-foundation homes. The homeowner's life does not stop because the power company's infrastructure failed.
An estimated $3,000–$7,000 a year in insurance savings, structurally — every wind-mitigation credit maxed out.
