Attribute comparison
| Attribute | Wood framing | Lok-N-Blok |
|---|---|---|
| Material core | Dimensional lumber + sheathing | Patented Envion composite interlocking block |
| Envelope build approach | Framing crew, hurricane straps, post-assembly detailing | 2-person certified crew stacks pre-cut blocks, tensions top plate |
| Mortar / cure time | N/A (nailed) | None (interlocking geometry, tensioned plate) |
| Engineered wind rating | Low 100s without upgrades; low 140s with high-wind detailing | High-wind assembly target, project-specific |
| Fire rating | Combustible | Class A assembly path where specified |
| Termite vector | Yes | None (non-wood block profile) |
| Mold vector | Yes (cavity moisture) | Resistance profile subject to assembly documentation |
| MEP rough-in | Drill studs post-framing | Factory-cast channels in every block |
| Service life (typical) | 40–50 years | 50–100+ years (targeted durable wall profile) |
| End of life | Demolition to landfill | Disassemble + reuse blocks |
| Code certification | IRC with state amendments | Florida product approval, Miami-Dade NOA, and ICC-ES status under review |
| Insurance treatment | Standard hurricane-zone rating | Carrier-specific resilience review; no premium outcome promised |
What this table doesn't show
A static comparison table can't quote your project. The cost, schedule, and insurance math depend on inputs that are site-specific: your ZIP, your square footage, your carrier, your local labor market, your architectural complexity. The attributes above are materials-science and engineering facts; the dollars are per-project.
When you reserve a build, we scope a real quote for your project inside 24 hours. Insurance and code conversations should use the project-specific engineering package available at the time of review, then compare that result against your wood-frame baseline.
When wood framing is still the right call
- Cat 1–2 exposure zones. If historical peak winds on the site top out in the 90–100 mph range, a well-built wood-frame home is defensible.
- Budget cap is the binding constraint. Wood-frame is the lowest-cost envelope in most markets.
- Historical-district or design-review constraints. Some jurisdictions require wood framing for architectural continuity.
- Temporary structures. Service life and end-of-life aren't part of the ROI calculation.
When Lok-N-Blok wins decisively
- Any Cat 3+ hurricane exposure (Florida coast, Gulf coast, Atlantic coast, Outer Banks).
- Wildfire-corridor builds where Class A assembly path is required or strongly preferred.
- Production builders optimizing for inventory turn.
- Insurance-led customers (retirees, coastal second homes, income-producing coastal properties).
- Projects valuing 50–100+ year service life or reusable end-of-life.
