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 St. Catharines properties facing high wind loads or older heritage homes needing structural stabilization.
St. Catharines’ Spray Foam Strategy: Protecting Heritage & Waterfront Properties
Historic Brick & Masonry Retrofitting
St. Catharines’ core features unique double-brick masonry that requires modern 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.Port Dalhousie Waterfront Defense
Properties near the water face aggressive moisture drive and high winds. Our 2lb Closed Cell Spray Foam Insulation acts as a certified Class II vapor retarder, sealing your walls against humidity and blocking wind wash that renders traditional insulation ineffective.Basement Moisture & Foundation Defense
Many St. Catharines 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
