The baseline
A 2,000 sq ft code-built house in Milan typically wants somewhere between 1000 and 1200 gallons of oil a year, or the propane, pellet or cord wood equivalent. That is the number a percentage saving has to be measured against.

Steel insulated panels in Milan, NH.
Building in Milan usually means doing more of it yourself, further from the nearest supplier, with fewer trades available and a heating season long enough to punish a mediocre wall.

What Milan projects ask of a wall.
Wooded and open parcels, wells and septic, long power runs, unpaved access in places, and a real chance the owner is doing part of the work.
A panel package collapses four trades into one and arrives in a single delivery, which matters most where trades are scarce. Panels are numbered to match the drawings, all hardware ships with the package, and the illustrated assembly manual runs to 36 pages — owner-builders set these regularly. For off-grid and solar-paired projects, a load 70–75% below code means a smaller array, a smaller battery bank and a generator that rarely starts.
What we typically supply in Milan: owner-built and custom homes, off-grid and low-energy builds, workshops, barns and small rentals.
The arithmetic in zone 7
What the wall is worth here, in fuel.
Zone 7 is the coldest climate in the region, with 8,000 to 9,500 heating degree days. This is where the gap between a code wall and a thermally broken R-61 panel is widest, and where it closes fastest.
The same house in panels
At an effective R-51 to R-61 with the studs thermally broken from the exterior face, heating energy typically falls 70 to 75% — on the order of 270 to 360 gallons. At current delivered prices that is thousands of dollars a year, every year the building stands.
The upfront return
A design load that low lets the mechanical system be sized at roughly half. Smaller equipment, smaller ductwork, less dedicated electrical service, and on solar-paired projects a smaller array and battery bank. That money never leaves the construction budget.
Baselines are typical for the climate zone and floor area, not a promise about your building. Send plans and we will run the numbers on the actual design.
Four products, one panel
Structure, insulation, sheathing and vapour barrier arrive together.
Each panel bonds light gauge galvanised steel structural members to EPS with a patented composite joining technology, and does the work of four separate trades. That is why the framing phase for an average house is about three days rather than three weeks.
Exterior wall panel
5.5″ or 7.5″ thick, up to 4′ × 12′, effective R-51 to R-61, up to 42,000 plf LRFD, ready for direct application of the final cladding.
Roof panel
Load bearing, so trusses open to every 4–6 ft. Two panels connect at the ridge for cathedral ceilings and A-frames with no intermediate support.
Interior and ceiling panels
3.5″ at R-28 for partitions, tiny homes and quiet rooms; ceiling panels pre-chased and ready for direct sheathing.
Floor and below-grade
Concrete floor panels span up to 50 ft with minimal shoring and cut concrete volume by around 40%; below-grade panels are rated for foundation and retaining walls.
How it works
Four steps from a Milan sketch to a finished shell.
01
Send what you have
Architect’s drawings, a plan-service set, or a hand sketch with rough dimensions and a note about storeys and roof. We will tell you what is missing.
02
Free take-off and price
We panelize the building on paper and return a package and a delivered price to your Milan site — no cost, and an honest comparison against building it the usual way.
03
Shop drawings
Two to four weeks. Our drafters work with your architect and engineer: every panel numbered, every rough opening located, beams and headers integrated.
04
Delivery and assembly
Panels arrive bundled in wall-line order with track, screws and hardware. One framer and two helpers close in an average house in about three days.
Code and compliance in New Hampshire
Your plan reviewer has seen this before.
New Hampshire has adopted the state energy code statewide, and a documented effective R-51 to R-61 wall clears its envelope requirements without exterior continuous insulation.
Structural
IAPMO load tables for construction types II–V, signed and sealed by BEI Engineering. Up to 42,000 plf LRFD in bearing and 2,420 plf in shear with a 2.0 safety factor.
Fire and acoustics
Two-hour load-bearing, one-hour load-bearing and two-hour non-load-bearing assemblies. EPS smoke and flame spread, self-ignition and flash ignition data. STC-rated assemblies for party walls.
Envelope and weather
Intertek thermal performance assessment, thermal zone map, ASTM E283, E331 and E330 air and water penetration testing, HUD Bulletin 1072 compliance and documented manufacturing tolerances.
Questions from Milan
Straight answers before you commit.
Can an owner-builder set these?
Many do. Every panel is numbered to match the drawing, bundles arrive in wall-line order with track and screws included, and the 36-page illustrated assembly manual on our resources page is written to be read before the truck arrives.
Does it suit an off-grid house?
It is the best case for it. Cutting the heating and cooling load by up to 75% means a smaller array, a smaller battery bank and a generator you rarely need to start.
Is there a minimum project size?
No. We have supplied everything from a garden shed to a six-storey building, and the drawings, labelling and delivery work the same way at either end.
Do you really deliver to Milan?
Yes. We supply the whole of New England from our base in Keene, New Hampshire, with panels manufactured in Radford, Virginia. Freight to Milan is a quoted line item on the estimate, not a surprise at the end, and it is a small number against what the wall saves over the life of the building.
Is it more expensive than building with lumber?
The panel package costs more than a lumber package. The finished wall usually costs less, because the panel replaces framing, insulation, sheathing and vapour barrier and cuts framing labour by roughly half — then the mechanical system shrinks by about 50%. We will price it both ways so you can see the whole picture rather than one line of it.
How do I get a price for my Milan project?
Send plans, a sketch or a description with rough dimensions to our team. You get a panel take-off and a delivered price at no cost, usually within a few days, plus a note on anything in the design that is fighting the system while it is still cheap to change.
Building in Milan? Let’s price it.
Plans, a sketch or a napkin. We will tell you what the panel package costs delivered to your site — and what it saves against stick framing.
