R-17.4 Insulated Garage Doors Winnipeg
Maximum thermal protection against Manitoba's extreme winter conditions. Heavy-duty 2-inch panel thickness with high-density continuous polyurethane insulation, thermal break engineering, double torsion springs, and dual-sided color matching stocked and custom sized in Winnipeg.
Why R-17.4 Insulation is Essential for Winnipeg Homes
In Winnipeg, your garage door represents the largest single opening in your home's building envelope. When outside temperatures drop to -30°C or -40°C, an uninsulated or poorly insulated door acts as a giant heat sink, drawing warmth out of adjacent living spaces, freezing water lines, and dramatically increasing home heating bills.
Maxon Doors utilizes a continuous, high-pressure injected polyurethane core rated at R-17.4 within a rigid 2-inch thick panel. Polyurethane expands into every corner of the steel cavity, eliminating air pockets and bonding the inner and outer steel skins into a rigid, highly durable composite section that resists flexing under high prairie wind loads.

Anatomy of a Maxon Insulated Door
Every element of our insulated garage door is selected to deliver durability and thermal efficiency:
2-Inch Panel Thickness (R-17.4 Core)
Full 2-inch (50.8 mm) structural panel depth filled with continuous high-density polyurethane foam. Delivers roughly double the insulating efficiency of polystyrene (Styrofoam) inserts of the same thickness.
Thermal Break Barrier
Prevents conductive thermal transmission between the exterior steel skin and interior steel face, stopping frost and condensation from forming indoors.
Double Torsion Spring System
Heavy insulated panels require precise counterbalance. We install dual torsion springs calibrated to door weight for smooth, effortless motor operation.
Heavy Gauge Steel Construction
Structural steel panels built to American standard specifications resist dents, impacts, and high prairie gusts.
Sub-Zero Astragal Seal
Heavy-duty bulb weatherstrip at the base conforms to uneven concrete floors to block blowing snow, ice, and drafts.
