The baseline
A 2,000 sq ft code-built house in Northampton typically wants somewhere between 700 and 850 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.

What Northampton projects ask of a wall.
Valley in-fill, historic fabric, strong design review culture.
Two things matter to this market and the panel answers both. First, performance with documentation: effective R-51 to R-61, tested and sealed, contributing to LEED credits, manufactured in a zero-waste facility from recycled content and fully recyclable at end of life. Second, a summer-shaped schedule — a shell that closes in days is the difference between finishing before term and not.
What we typically supply in Northampton: Net-zero and Passive House homes, mixed-use in-fill, institutional.
The arithmetic in zone 5A
What the wall is worth here, in fuel.
Zone 5A runs roughly 5,500 to 6,500 heating degree days — a long enough heating season that the envelope, not the equipment, sets what the building costs to run.
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 189 to 255 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 Northampton 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 Northampton 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 Massachusetts
Your plan reviewer has seen this before.
Massachusetts building here means the base energy code and, in many municipalities, the stretch code or the specialised opt-in code. The panel clears the envelope requirements of all three 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 Northampton
Straight answers before you commit.
How does it compare to a double-stud wall?
Same or better performance in five and a half or seven and a half inches instead of twelve to sixteen — and no organic material in the assembly to manage for moisture.
Does it help with certification?
It removes the hardest part of the envelope target. Windows, ventilation and orientation remain your work.
Will it contribute to LEED?
It contributes to several credits — energy performance, recycled content, waste reduction and indoor air quality among them. Our LEED page walks through which and how.
Is the material healthy indoors?
The panels do not off-gas and contain no carcinogens, pathogens or allergens. There are no formaldehyde binders and no treated lumber, and nothing in the assembly feeds mold or mildew.
Can the work be done between terms?
That is exactly the schedule panels suit. Framing labour halves, the shell closes in days, and nothing in the assembly needs to dry before interior trades start.
Do you really deliver to Northampton?
Yes. We supply the whole of New England from our base in Keene, New Hampshire, with panels manufactured in Radford, Virginia. Freight to Northampton 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 Northampton 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.
