Proper insulation is the foundation of an energy-efficient home, and spray foam insulation is the gold standard. Our professional spray foam insulation services create an airtight seal that prevents heat loss in winter and keeps your home cool in summer. This translates to significant savings on your energy bills while dramatically improving indoor comfort. Spray foam also acts as a moisture barrier, preventing condensation and mold growth in your attic and walls.
According to Natural Resources Canada, homeowners can reduce heating and cooling costs by 20–50% after adding spray foam insulation to an attic or walls. In Edmonton, where winter temperatures regularly drop below –20°C, the savings are especially significant. The investment typically pays for itself within 3 to 7 years through reduced utility bills.
Yes — spray foam insulation is one of the highest-return home upgrades in Edmonton's climate. It creates an airtight seal that standard batt insulation cannot match, prevents ice damming on the roof edge, eliminates condensation in the attic, and significantly reduces furnace and air conditioning run time. Open-cell spray foam achieves R-3.5 per inch; closed-cell achieves R-6 to R-7 per inch.
Yes. Ice dams form when heat escaping through an under-insulated attic melts snow on the roof, which then refreezes at the cold eaves. Spray foam insulation eliminates this heat transfer by creating an airtight thermal barrier, preventing ice dams from forming. This is one of the most common and costly winter roofing problems in Edmonton.
Properly installed spray foam insulation lasts the lifetime of the building — typically 80 years or more. Unlike batt insulation, it does not sag, shift, or lose effectiveness over time. It is also resistant to moisture, mold, and pests.
