The Spray Foam Insulation Standard in London

London Spray Foam Authority
VERIFIED LOCAL AUTHORITY

In London, the Forest City, where the historic charm of Wortley Village meets the modern expansion of the university corridors, the standard for building performance is paramount. For over 15 years, we have served as the definitive choice for London homeowners who demand the absolute best in Spray Foam Insulation performance. From the century-old brick homes in Old North to the high-performance new builds in Byron, our crews deliver the surgical precision required to pass inspection and slash energy bills.

London properties often face significant air leakage and Spray Foam bridging, particularly in older homes with double-brick masonry. Standard fiberglass batting is fundamentally insufficient in these buildings; it allows moisture drive and air movement that leads to drafts and cold spots. Our 2lb Closed Cell Spray Foam Insulation acts as a monolithic air seal and vapor barrier, providing extreme R-values in a thin profile. This allows you to modernize your home’s Spray Foam Insulation performance while protecting its historic character and maximizing interior living space.

We are experts in London Building Division standards, specializing in the high-efficiency demands of the region's rapid growth and sensitive retrofitting of its established core. Whether you are aiming to eliminate 'cold floor' drafts or soundproofing a secondary suite near Western University, our local rigs deliver the surgical accuracy and 5-star verified performance your project deserves. When you choose our team, you are investing in a lifetime of comfort, structural stiffness, and 5-star energy savings.

TECHNICAL SPECS

What We Use & Why

Our material selection is driven by performance, code compliance, and lifetime durability.

← Tap a tab above to switch specs β†’

FOAM TYPE2lb Closed-Cell

High-density polyurethane foam from manufacturers like Huntsman and BASF.

THICKNESS3.5" (Walls)

Custom depth applied on-site to ensure a seamless monolithic seal with zero gaps.

PERFORMANCER-22+

Certified R-value of 6.0-7.0 per inch, far exceeding standard fiberglass performance.

COMPLIANCECCMC #14077-L

Fully certified for use in Canadian construction and 100% code-compliant.

ENGINEERING RATIONALE

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.

EXPERT INSIGHTS

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 London properties facing high wind loads or older heritage homes needing structural stabilization.

London’s Spray Foam Strategy: Protecting Heritage & Institutional Assets

Historic Brick & Masonry Retrofitting

London’s 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.

Byron New Build Air Sealing

The expansion in Byron features modern homes that require advanced air-sealing to hit modern energy targets. We provide precision sealing for rim joists, headers, and attic flats, ensuring these new builds are as energy-efficient as they were engineered to be.

Basement Moisture & Foundation Defense

Many London 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.
