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 Kingston properties facing high wind loads or older heritage homes needing structural stabilization.
Kingston’s Spray Foam Strategy: Protecting Limestone Heritage & Waterfront Assets
Historic Limestone Retrofitting
Kingston’s limestone core requires specialized Spray Foam solutions. We apply closed-cell foam directly to the interior masonry, providing an airtight vapor barrier and R-7 per inch of thickness. This protects the historic structure from moisture damage while making it significantly warmer.Lakefront Moisture Defense
Properties near the water face aggressive moisture drive and wind shears. Our 2lb Closed Cell Spray Foam Insulation acts as a certified Class II vapor retarder, sealing walls against humidity and blocking wind wash that renders traditional insulation ineffective.Basement Moisture & Foundation Defense
Many Kingston properties suffer from cold floors caused by unsealed foundations. Our 2lb Closed Cell Spray Foam Insulation acts as an impermeable moisture barrier, sealing out ground vapor and stabilizing internal temperatures while reinforcing the foundation.
Ontario Building Code — R-Value Requirements
* Wall R-value varies R-22 to R-24 depending on architectural drawings

“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.”
“Upgraded our drafty attic with closed-cell spray foam. The crew was very polite, laying drop cloths throughout the house. Energy bills dropped by almost $110/month. The foam has already paid for itself.”
“We hire them regularly for our home addition projects. They execute site protection flawlessly—taping all windows, doors, and flooring before spraying. Their cleanup is thorough, leaving the job site spotless.”
“Our cold room was constantly sweating and growing mold. They sprayed closed-cell insulation over the walls and ceiling. Completely fixed the condensation issue. Prompt, clean, and reasonably priced.”

Yes. Closed-cell spray foam is the best solution for historic limestone homes because it provides a vapor barrier and high R-value in a compact profile, protecting your structure from moisture while making the home significantly warmer.
Lake-effect humidity and high winds can bypass traditional insulation. Closed-cell spray foam is ideal because it acts as a vapor barrier and air seal that doesn't absorb moisture.
