Choosing an Insulated Garage Door in Alberta: R-12 vs. R-16 Polyurethane Explained

In Greater Edmonton, we strongly recommend polyurethane-injected sandwich doors (R-16 to R-18) over pan doors with glued-in polystyrene styrofoam panels (R-6 to R-9).

Polyurethane foam expands to bond tightly to both interior and exterior steel skins, turning each section into a rigid structural beam that resists driveway basketball dents and howling prairie winds.

Even better: Steel-Craft Door Products manufactures their Elite and Thermocraft series right here in Edmonton, meaning replacement panels and hardware are always available locally without 8-week cross-border shipping delays.
