ThermaSteel's patented composite technology bonds light-gauge structural steel to EPS foam — a stronger, lighter wall that installs in half the time. We're an independent ThermaSteel distributor, and we erect what we sell.
Panels arrive on site ready to install — no additional structure, no separate insulation, no sheathing, no vapor barrier. Four steps accomplished every time a panel goes up.
Light-gauge structural steel members — 2-hour fire-rated load-bearing assembly, tested to Richter-9 seismic and the Miami-Dade hurricane protocol.
Effective whole-wall R-51 to R-61 with the studs broken from the exterior face — no thermal bridging anywhere in the assembly.
Steel and EPS: no rot, no delamination if it gets wet, no food for termites or carpenter ants, non-combustible core.
Resists mold and mildew, low smoke and flame spread, 100% recyclable at end of life.
Exterior, interior and below-grade walls, floors and roofs — including curved walls, round windows, cathedral ceilings and A-frames.
Panels ship pre-cut, numbered to the drawings, bundled in wall-line order with track, screws and hardware. Your own framer, ~2 hours of training, a screw gun.
Typical whole-assembly values for cold-climate construction. ThermaSteel figures are from the Intertek thermal report and sealed load tables.
| ThermaSteel | 2×6 stick | OSB-faced SIP | ICF | |
|---|---|---|---|---|
| Effective whole-wall R | R-51 to R-61 | R-15 to R-17 | R-21 to R-27 | R-22 to R-26 |
| Thermal bridging | None | Every stud & plate | At splines & joints | At ties & openings |
| Framing time, avg house | ~3 days | 2–4 weeks | 4–7 days | 1–2 weeks + pour |
| Trades to close the shell | One | 4–5 | 2–3 | 2–3 |
| If it gets wet | Steel & EPS — fine | Rot & mold risk | Skins can delaminate | Interior finishes at risk |
| Termites | Not a food source | Yes | Yes — the skins | No |
Architect's drawings, a plan-service set, or a hand sketch with rough dimensions. We'll tell you what's missing.
We panelize the building on paper and come back with a package and a delivered price — no cost, no obligation, with a like-for-like comparison against framing + insulation + sheathing.
Our drafters work with your architect and engineer. Every panel numbered, every opening located, beams and headers integrated. Drawings arrive weeks before the panels.
Panels arrive bundled in wall-line order with all hardware. One framer and two helpers close an average house in about three days.
New Hampshire allows an ADU on most single-family lots. A panelized shell shortens the weather-exposed part of the build to a few days, and the R-61 envelope means the heating bill on a small unit is negligible.
IAPMO load tables for construction types II–V, two-hour fire-rated load-bearing assemblies, Florida and Miami-Dade hurricane approval, HUD compliance, seismic testing and ASTM air-and-water penetration reports.
The panel package costs more than a lumber package. The finished wall usually costs less, because the panel replaces framing, insulation, sheathing and vapor barrier plus the labor for all of it. The free estimate comes with a like-for-like comparison.
Your own framer, in almost every case. Training is under two hours for a crew that has framed before, and the only power tool required is a screw gun. The assembly manual runs to 36 illustrated pages.
Two to four weeks for shop drawings after we have your plans, then manufacturing, then delivery. On site, an average house shell goes up in about three days.
Curved walls, round windows, cathedral ceilings and A-frames have all been built. We panelize your architect's drawings.
Records are kept for 25 years. If you need to add or replace a panel, it can be matched to the original spec and shipped quickly. A 10-year material warranty covers the panels.
Tell us the room, a rough budget range and when you'd like to start. We'll come back with next steps and a realistic timeline — no pressure, no mystery pricing.
