Attic Spray Foam Insulation
In southern Ontario homes, the attic floor and roof assembly are responsible for over 40% of overall heating and cooling loss. Rising warm air drives continuous exfiltration through framing gaps, pot lights, and plumbing stacks. SprayCOR stops this stack effect at the core with seamless closed-cell barrier seals.
Eliminates air convection paths into cold roof cavities during Hamilton winters.
Maintains uniform deck temperatures so snow does not melt and refreeze at gutters.
Engineered attic assemblies
We evaluate your roof line, mechanical ducts, and storage requirements to recommend the exact building-science assembly suited to your floor plan.
Hot-roof / unvented deck
Creates a conditioned attic space, bringing ductwork and mechanicals inside the home's thermal boundary. Ideal for cathedral ceilings and finished attic conversions.
Traditional vented attic floor
Permanently seals ceiling penetrations, wiring holes, and top plates from escaping interior air, leaving passive soffit-to-ridge venting fully functional.
All SprayCOR attic installs utilize CAN/ULC S705.1 compliant polyurethane formulations applied by Canadian-certified applicators.
Our preparation protocol
A permanent thermal barrier is only as reliable as the preparation behind it. We follow strict containment protocols before any foam expands.
Floor & pathway protection
We lay heavy poly sheeting and drop cloths from entry doors straight to the attic hatch, keeping living areas spotless.
Electrical & can light isolation
Pot lights, junction boxes, and chimneys are boxed or shielded with non-combustible covers prior to spraying.
Soffit ventilation baffling
Rigid ventilation baffles are fastened along the eaves to guarantee continuous airflow when insulating attic flat floors.
Substrate & moisture validation
Technicians measure wood moisture levels across the roof deck before applying certified medium-density foam.

Thermal Performance & Durability
Why insulate your attic
Up to 35% of household heat loss escapes straight through an unsealed roof. Spraying your attic deck and floor locks conditioned air where you live and protects your roof structure for decades.
Stop conditioned air from migrating upwards through recessed lights, chases, and top plates. Your HVAC system maintains stable comfort on every floor without running constantly.
Creates an airtight, impermeable thermal boundary that keeps humid indoor air from hitting cold roof plywood, eliminating the primary cause of winter condensation and attic mold.
Prevents indoor heat from melting snow on roof sheathing, stopping the freeze-thaw cycle that causes severe ice damming, soaked soffits, and winter gutter damage.
