How It's Built
A Smarter Way to Build
Zona Verde homes are built from Engineered Structural Insulated Panels (ESIPs) instead of traditional wood framing. Each panel is both structure and infrastructure, with electrical, plumbing, and insulation integrated at the factory. The result: construction time cut by 50–70% versus stick-built (and 30–50% versus modular), with a stronger, better-insulated home that requires far less maintenance.
R-48 insulation
More than double the typical home
50-year lifespan
No rot, no termites, fire resistant
4–6 month delivery
Full occupancy, not just superstructure
F2 tornado rated
Third-party certified
By the Numbers
Zona Verde vs. Conventional Stick-Built
| Feature | Zona Verde | Stick-Built |
|---|---|---|
| Primary structure | Engineered insulated panels (ESIP) | Wood framing |
| Insulation | 2x better than typical (R-48) | Standard (R-15 to R-22) |
| Pest resistance | Sealed galvanized skins (no termites or rodents) | Requires ongoing treatment |
| Snow load | Heavy snow certified | Varies by region |
| Structural engineering | Independently certified | Varies |
| Superstructure time | Weeks | 3–4 months |
| Total project time | 4–6 months | 12–18 months |
| Electrical | Factory pre-routed; electrician connects on-site | Installed on-site by electrician |
| Plumbing | Factory pre-routed; plumber connects on-site | Installed on-site by plumber |
| Interior walls | Factory powder-coated panels (no drywall) | Drywall, tape, mud, paint |
| Exterior finish | Factory powder-coat finish (outlasts traditional paint) | Siding + paint (repaint every 5–10 years) |
| On-site trades required | Small trained crew + electrician + plumber | 8–12 specialized trades |
| Insect/rodent resistance | ||
| Fire resistance | ||
| Durability | No rot, warp, or cracking | Wood (ongoing maintenance) |
| Maintenance | Minimal (no re-siding needed) | Ongoing (paint, siding, pest treatment) |
| Solar ready | Yes (roof engineered for solar arrays; installation not included) | Requires roof assessment |
R-value comparisons are based on the U.S. Department of Energy's insulation guidelines, which recommend R-13 to R-21 for exterior walls in most U.S. climate zones. Zona Verde's structural panels are independently certified to ASCE 7 minimum design load standards by Parth Shah Consulting Engineers.
Inside the Panel
Everything Built Into One Wall
Panels arrive numbered and color-coded, slide onto a track system, and lock together. A small crew assembles the full structure without specialized trades.

FAQ
Common Questions
Zona Verde homes use a Polyisocyanurate (PIR) foam core with an R-value of 48, more than double the R-15 to R-22.5 typically found in stick-built or prefab homes. The 150mm (6-inch) core has a thermal conductivity of 0.03 W/m·K, delivering superior year-round comfort and significantly lower energy bills.
Yes. Zona Verde homes are engineered to withstand wind speeds of 109 mph and are rated F2 tornado resistant. The panels' structural skins use FY310 galvanized steel certified to ASCE 7-10 structural standards.
Yes. Zona Verde panels pair galvanized steel structural skins with a PIR foam insulation core, which provides superior fire resistance compared to wood-framed homes. The materials are non-combustible and won't contribute to fire spread. The powder-coated exterior finish also resists fire.
Electrical conduit and plumbing runs are pre-routed through each panel at the factory before shipping. On-site, licensed electricians and plumbers only need to make final connections with no cutting into walls required. This eliminates the most time-consuming rough-in trades that slow down traditional construction.
A typical stick-built home has wall insulation rated between R-15 and R-22.5. Zona Verde's PIR foam core delivers R-48, more than double the industry standard. SIP homes typically achieve R-22.6. The higher R-value means lower heating and cooling costs for the life of the home.
Minimal. The factory powder-coated exterior doesn't require repainting or re-siding. The panels don't rot, warp, crack, or attract termites or rodents. Solid panel walls eliminate drywall cracks and nail pops. The result is significantly lower lifetime maintenance costs compared to wood-framed construction.
