What We Use & Why
Our material selection is driven by performance, code compliance, and lifetime durability.
← Tap a tab above to switch specs →
High-density polyurethane foam from manufacturers like Huntsman and BASF.
Custom depth applied on-site to ensure a seamless monolithic seal with zero gaps.
Certified R-value of 6.0-7.0 per inch, far exceeding standard fiberglass performance.
Fully certified for use in Canadian construction and 100% code-compliant.
Exterior walls are the primary defense against Ontario's wind and cold. 3.5 inches of 2lb closed-cell foam fills the stud cavity completely, eliminating the 'air gaps' found in standard batt insulation. This prevents convection loops and stops heat from leaching through your framing via thermal bridging.
Technical Depth: Insane Benefits of Sprayfoam
Understanding the physics of high-performance insulation helps you make the right choice.
Standard fiberglass batts provide zero structural benefit. In contrast, 2lb closed-cell spray foam is a rigid, dense material that actually bonds building components together.
Tests have shown that walls filled with 2lb spray foam can have up to 300% to 400% more racking strength than uninsulated walls. It acts as a structural glue for your framing.
This is critical for Ajax properties facing high wind loads or older heritage homes needing structural stabilization.
Ajax’s Spray Foam Modernization: From Post-War Homes to Modern Audley
Modernizing South Ajax Bungalows
Many homes in Ajax’s established neighborhoods were built with minimal insulation. We specialize in 'gut-to-the-studs' retrofits, applying closed-cell foam directly to exterior walls. This provides the highest R-value per inch, allowing you to hit modern energy standards without losing interior space.Audley Subdivision Air Sealing
The rapid expansion of Audley and North Ajax features large homes that require advanced air-sealing. We provide precision sealing for rim joists, headers, and cantilevered floors, ensuring these new builds are as energy-efficient as they were designed to be.Basement Moisture & Foundation Sealing
Ajax foundations, particularly near the lake, are prone to moisture seepage. Our 2lb Closed Cell Spray Foam Insulation acts as an impermeable vapor retarder, sealing the concrete from the inside to stop dampness, mold, and rot while providing a warm, livable basement space.

“Wonderful service. They helped us qualify for the Enbridge energy rebate by upgrading our old attic floor to R-60. The installers were very clean, laying plastic over everything. Highly recommend.”
“Had our entire basement insulated with closed-cell spray foam before finishing. The crew showed up on time, protected everything with plastic sheeting, and were done in one day. Basement stays warm now even in January. Highly recommend.”
“We hired SPF Solutions for our century home renovation. They sprayed the attic to hit R-60 compliance—the difference in heating costs is night and day. Professional team, fair pricing, and they cleaned up after themselves.”
“Used them to spray the garage ceiling below our master bedroom. No more freezing floors in winter. The 2lb closed-cell foam stopped all cold drafts. Fast scheduling and very clean execution.”
“As a custom home builder, I need sub-trades that show up on time and respect the schedule. Their in-house crew sprayed the entire building envelope. Passed framing inspection first try with zero trimming delays.”
“They sealed our crawl space with closed-cell spray foam. The damp, musty smell in our home is completely gone. They did an excellent job with prep work, covering everything in plastic and tarps.”

Most Ajax homeowners see a 30% to 50% reduction in heating and cooling costs after upgrading to a full spray foam air seal, as it stops the physical movement of air through your walls and attic.
Yes. Once fully cured (24 hours), spray foam is inert and non-toxic. It actually improves indoor air quality by blocking outdoor allergens and pollutants from entering your home through gaps in the building envelope.
Absolutely. We are experts in OBC requirements for secondary suites, providing the Spray Foam and fire separation solutions (like DC315 coating) required to pass Durham Region inspections.
