Understand the difference

How Polar Maxima outperforms conventional construction

R-value (insulation rating) measures how well a wall and building component keep heat in —
the higher the number, the warmer and more efficient your home.

Code minimum (NBC — National Building Code)

Typical stick-built wall in a cold region

National Building Code 2×6 wall cross-section showing drywall, furring, poly vapour barrier, 2×6 studs with R-20 batt insulation, OSB, EPS, wind barrier, strapping, and exterior siding.

Total wall insulation: R-24

  • 2×6 wood or light gauge steel (LGS) studs + batt insulation
  • 1″ EPS (Expanded Polystyrene) in colder climate zones
  • Interior strapping + polyethylene vapour barrier (optional)
  • Attic ~R-50

Insulation types explained

R per inch tells you how much heat resistance you get for each inch of material. $–$$$$$$ compares typical installed material cost — not labour or whole-wall price.

Fibreglass batt R-3.5 / in · $
Spun glass in pre-cut batts — the most common cavity fill in stud walls. Low cost, but performance drops if batts are compressed or leave gaps.
Cellulose (blown) R-3.7 / in · $
Recycled paper fibre, blown into attics or enclosed cavities. Fills irregular spaces well; needs vapour control to manage moisture.
EPS (Expanded Polystyrene) R-4 / in · $$
White rigid foam board — often used as exterior sheathing in cold climates (as in code-minimum walls). Economical board insulation; protect from water.
Mineral wool batt R-4.2 / in · $$
Rock or slag fibre batts. Fire-resistant and good for sound; denser than fibreglass with slightly higher R per inch.
XPS (Extruded Polystyrene) R-5 / in · $$$
Closed-cell rigid foam (often blue or pink). Moisture-resistant — common below grade and on exterior foundations.
Polyiso board R-6 / in · $$$$$
Foil-faced rigid board with high R per inch among sheet goods. Note: R-value can fall in extreme cold unless specified for your climate.
Closed-cell spray foam (polyurethane) R-6.5 / in · $$$$$$ Polar system
Sprayed in place; expands to air-seal gaps while insulating. Highest material cost; requires professional installation. Polar exterior wrap uses this technology for continuous outside insulation.

Exterior envelope

Polar Wall insulation

Advanced exterior panel system for a continuous thermal envelope — passive house, net-zero, and energy-efficient construction in extreme climates.

Polar Wall cross-section showing exterior XPS insulation and structure
Exterior insulation wraps the structure — bridges moved outside the heated line
  • Structural strength + moisture control in one panelized system
  • Streamlined install for new builds and deep retrofits
  • Factory-ready modules pair with Polar Maxima kit homes

Below grade

Polar Guard Foundation

Insulated formwork integrating footing and foundation walls — strength during pour, later-season placement, and eliminated thermal bridging at the footing joint.

Single pour sequence

Footing and walls formed as one interconnected system — faster, stronger placement even in later seasons.

XPS stays in place

HD panels hold concrete during pour and remain as continuous insulation — no thermal bridge at the footing joint.

Drainage ready

Designed cavity preserves room for waterproofing and perimeter drainage without breaking the envelope.

Polar Roof

Continuous thermal envelope above the structure — comfort and efficiency for passive, net-zero, and sustainable roofs from tiny homes to multi-storey.

Polar Cub

Closed-cell spray foam exterior wrap on a 2×6 cavity — attic ~R-60. ~15% heating & cooling vs baseline (stick/LGS).

R-50 wall · +R-30 wrap · 5″

Polar Bear

Near Passive House wall performance — attic ~R-80. ~10% heating & cooling vs baseline (stick/LGS).

Polar Extreme

Maximum stick-built assembly — attic ~R-100. ~5% heating & cooling vs baseline (stick/LGS).

CLT and post & beam use different wall assemblies (see comparison above). Polar Foundation and Polar Roof use variable R-values tailored to site and code.

Why Polar Max 360
