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 Oshawa properties facing high wind loads or older heritage homes needing structural stabilization.
Oshawa’s Spray Foam Modernization: From Classic Bungalows to Modern Estates
Modernizing Oshawa’s Post-War Bungalows
Many homes in Oshawa’s established neighborhoods were built with minimal insulation. We specialize in 'gut-to-the-studs' retrofits, applying closed-cell foam directly to exterior walls and rim joists. This provides the highest R-value per inch, allowing you to hit modern energy standards without losing interior living space.North Oshawa Custom Build Experts
The rapid growth in North Oshawa and Taunton features large, complex homes that require advanced air-sealing. We partner with local builders to provide unvented attic solutions and high-performance wall systems, ensuring these new builds pass their Spray Foam inspections on the first attempt.Basement Moisture & Cinder-Block Sealing
Older Oshawa foundations, especially those built with cinder-blocks, are prone to moisture seepage. Our 2lb Closed Cell Spray Foam Insulation acts as an impermeable vapor retarder, sealing the blocks from the inside to stop dampness, mold, and rot while providing a warm, livable basement space.

* Wall R-value varies R-22 to R-24 depending on architectural drawings

“Passed our building inspection with flying colors. The DC315 application met the 15-minute thermal barrier requirements under the Ontario building code. Highly professional service and documentation.”
“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.”
