The baseline
A 2,000 sq ft code-built house in St. Albans typically wants somewhere between 850 and 1000 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 St. Albans, VT.
St. Albans carries the housing stock of an older industrial economy: buildings worth saving, buildings past saving, and a constant question of whether to rehabilitate or replace.

What St. Albans projects ask of a wall.
Mill and canal parcels, dense village fabric, older foundations of uncertain dimension, and utilities that were laid out for a different century. Access is usually workable but rarely generous.
Panels answer both halves of the question. On a replacement build, the shell goes up in days on the existing footprint. Inside an existing structure, interior and thermal-separation panels are used for party walls and inserted floors, with documented STC-rated assemblies where units share a wall.
What we typically supply in St. Albans: replacement housing, mill and upper-floor conversions, small multi-family, and light commercial.
The arithmetic in zone 6A
What the wall is worth here, in fuel.
Zone 6A runs roughly 7,000 to 8,000 heating degree days. A code-minimum wall spends a large share of that season conducting heat straight through its own framing.
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 230 to 300 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 St. Albans 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 St. Albans 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 Vermont
Your plan reviewer has seen this before.
Vermont’s Residential Building Energy Standards and its stretch code are among the most demanding in the country. A thermally broken panel at effective R-51 to R-61 clears them without adding a layer of exterior 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 St. Albans
Straight answers before you commit.
Can I build on an existing foundation?
Usually yes. We take the as-built dimensions off what is actually in the ground rather than off the original drawings, and panelize to them, so the package arrives square to reality.
Do panels work inside an existing shell?
Regularly. Interior panels are used for party walls, thermal separations and inserted floors within existing buildings, and the 3.5 inch panel is thin enough not to eat the floor plan.
Is rehabilitation or replacement cheaper?
It depends on what is left of the original structure. What we can tell you precisely is what a new panel shell costs delivered, so you have a real number on one side of the comparison instead of two estimates.
Do you really deliver to St. Albans?
Yes. We supply the whole of New England from our base in Keene, New Hampshire, with panels manufactured in Radford, Virginia. Freight to St. Albans 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 St. Albans 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.

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.
